Concept
While developing extended graphical objects, I faced the necessity to get back to form objects — graphical objects on canvas to be implemented into extended graphical objects as control junctions for managing graphical object anchor points. In the previous article, I started the development of mouse events for form objects. Here I will finish my work on handling form object movement. We should be able to move any form on the chart. The form to be selected should be the one dragged by the mouse cursor and all chart tools should be correctly enabled and disabled depending on the object in due time.
Let's arrange tracking mouse events so that we are able to use the newly developed handlers for implementing all remaining interactions of a form object with the mouse. Apart from implementing dragging the forms by the mouse cursor and preparing "stubs" for other interaction events, I will add texts for the trade server return codes and execution error codes. Besides, I will add new properties for deal objects — StopLoss and TakeProfit levels present in the deal properties for some time now.
Improving library classes
In \MQL5\Include\DoEasy\Data.mqh, add the new message index:
MSG_LIB_PROP_BID, // Bid price MSG_LIB_PROP_ASK, // Ask price MSG_LIB_PROP_LAST, // Last deal price MSG_LIB_PROP_PRICE_SL, // StopLoss price MSG_LIB_PROP_PRICE_TP, // TakeProfit price MSG_LIB_PROP_DEAL_FEE, // Deal fee MSG_LIB_PROP_PROFIT, // Profit MSG_LIB_PROP_SYMBOL, // Symbol MSG_LIB_PROP_BALANCE, // Balance operation MSG_LIB_PROP_CREDIT, // Credit operation MSG_LIB_PROP_CLOSE_BY_SL, // Closing by StopLoss MSG_LIB_PROP_CLOSE_BY_TP, // Closing by TakeProfit MSG_LIB_PROP_ACCOUNT, // Account //--- COrder
and the text message corresponding to the newly added index:
{"Цена Bid","Bid price"},
{"Цена Ask","Ask price"},
{"Цена Last","Last price"},
{"Цена StopLoss","StopLoss price"},
{"Цена TakeProfit","TakeProfit price"},
{"Оплата за проведение сделки","Fee for making a deal"},
{"Прибыль","Profit"},
{"Символ","Symbol"},
{"Балансовая операция","Balance operation"},
{"Кредитная операция","Credit operation"},
{"Закрытие по StopLoss","Close by StopLoss"},
{"Закрытие по TakeProfit","Close by TakeProfit"},
{"Счёт","Account"},
//--- COrder
In the same file, complement the error message array:
//+---------------------------------------------------------------------+ //| Array of messages for trade server return codes (10004 - 10045) | //| (1) in user's country language | //| (2) in the international language | //+---------------------------------------------------------------------+ string messages_ts_ret_code[][TOTAL_LANG]= { {"Реквота","Requote"}, // 10004 {"Неизвестный код возврата торгового сервера","Unknown trading server return code"}, // 10005 {"Запрос отклонен","Request rejected"}, // 10006 {"Запрос отменен трейдером","Request canceled by trader"}, // 10007 {"Ордер размещен","Order placed"}, // 10008 {"Заявка выполнена","Request completed"}, // 10009 {"Заявка выполнена частично","Only part of request completed"}, // 10010 {"Ошибка обработки запроса","Request processing error"}, // 10011 {"Запрос отменен по истечению времени","Request canceled by timeout"}, // 10012 {"Неправильный запрос","Invalid request"}, // 10013 {"Неправильный объем в запросе","Invalid volume in request"}, // 10014 {"Неправильная цена в запросе","Invalid price in request"}, // 10015 {"Неправильные стопы в запросе","Invalid stops in request"}, // 10016 {"Торговля запрещена","Trading disabled"}, // 10017 {"Рынок закрыт","Market closed"}, // 10018 {"Нет достаточных денежных средств для выполнения запроса","Not enough money to complete request"}, // 10019 {"Цены изменились","Prices changed"}, // 10020 {"Отсутствуют котировки для обработки запроса","No quotes to process request"}, // 10021 {"Неверная дата истечения ордера в запросе","Invalid order expiration date in request"}, // 10022 {"Состояние ордера изменилось","Order state changed"}, // 10023 {"Слишком частые запросы","Too frequent requests"}, // 10024 {"В запросе нет изменений","No changes in request"}, // 10025 {"Автотрейдинг запрещен сервером","Autotrading disabled by server"}, // 10026 {"Автотрейдинг запрещен клиентским терминалом","Autotrading disabled by client terminal"}, // 10027 {"Запрос заблокирован для обработки","Request locked for processing"}, // 10028 {"Ордер или позиция заморожены","Order or position frozen"}, // 10029 {"Указан неподдерживаемый тип исполнения ордера по остатку","Invalid order filling type"}, // 10030 {"Нет соединения с торговым сервером","No connection with trade server"}, // 10031 {"Операция разрешена только для реальных счетов","Operation allowed only for live accounts"}, // 10032 {"Достигнут лимит на количество отложенных ордеров","Number of pending orders reached limit"}, // 10033 {"Достигнут лимит на объем ордеров и позиций для данного символа","Volume of orders and positions for symbol reached limit"}, // 10034 {"Неверный или запрещённый тип ордера","Incorrect or prohibited order type"}, // 10035 {"Позиция с указанным идентификатором уже закрыта","Position with specified identifier already closed"}, // 10036 {"Неизвестный код возврата торгового сервера","Unknown trading server return code"}, // 10037 {"Закрываемый объем превышает текущий объем позиции","Close volume exceeds the current position volume"}, // 10038 {"Для указанной позиции уже есть ордер на закрытие","Close order already exists for specified position"}, // 10039 {"Достигнут лимит на количество открытых позиций","Number of positions reached limit"}, // 10040 { "Запрос на активацию отложенного ордера отклонен, а сам ордер отменен", // 10041 "The pending order activation request is rejected, the order is canceled" }, { "Запрос отклонен, так как на символе установлено правило \"Разрешены только длинные позиции\"", // 10042 "The request is rejected, because the \"Only long positions are allowed\" rule is set for the symbol" }, { "Запрос отклонен, так как на символе установлено правило \"Разрешены только короткие позиции\"", // 10043 "The request is rejected, because the \"Only short positions are allowed\" rule is set for the symbol" }, { "Запрос отклонен, так как на символе установлено правило \"Разрешено только закрывать существующие позиции\"", // 10044 "The request is rejected, because the \"Only position closing is allowed\" rule is set for the symbol" }, { "Запрос отклонен, так как для торгового счета установлено правило \"Разрешено закрывать существующие позиции только по правилу FIFO\"", // 10045 "The request is rejected, because \"Position closing is allowed only by FIFO rule\" flag is set for the trading account" }, { "Запрос отклонен, так как для торгового счета установлено правило \"Запрещено открывать встречные позиции по одному символу\"", // 10046 "The request is rejected, because the \"Opposite positions on a single symbol are disabled\" rule is set for the trading account" }, }; //+------------------------------------------------------------------+
and add the new arrays — with the new execution error messages that were previously absent in the library but have already been added to MQL5:

These are new error messages introduced to MQL5 after the library creation started. It was not possible to add them to the library since they were not present in the language. Now that the error codes have been implemented and several terminal versions have already been released, I finally can add these error codes to the library with no risk of version incompatibility.
Now it is time to let the library message class to be able to refer to these classes when handling an error code.
To achieve this, in \MQL5\Include\DoEasy\Services\Message.mqh, add the code verification in terms of compliance with the value ranges and assign the string from the necessary array, corresponding to the error code, to the class error text in the m_text variable:
//+------------------------------------------------------------------+ //| Get messages from the text array by an ID | //+------------------------------------------------------------------+ void CMessage::GetTextByID(const int msg_id) { CMessage::m_text= ( //--- Runtime errors (0, 4001 - 4019) msg_id==0 ? messages_runtime[msg_id][m_lang_num] : #ifdef __MQL5__ msg_id>4000 && msg_id<4020 ? messages_runtime[msg_id-4000][m_lang_num] : //--- Runtime errors (Charts 4101 - 4116) msg_id>4100 && msg_id<4117 ? messages_runtime_charts[msg_id-4101][m_lang_num] : //--- Runtime errors (Graphical objects 4201 - 4205) msg_id>4200 && msg_id<4206 ? messages_runtime_graph_obj[msg_id-4201][m_lang_num] : //--- Runtime errors (MarketInfo 4301 - 4305) msg_id>4300 && msg_id<4306 ? messages_runtime_market[msg_id-4301][m_lang_num] : //--- Runtime errors (Access to history 4401 - 4407) msg_id>4400 && msg_id<4408 ? messages_runtime_history[msg_id-4401][m_lang_num] : //--- Runtime errors (Global Variables 4501 - 4524) msg_id>4500 && msg_id<4525 ? messages_runtime_global[msg_id-4501][m_lang_num] : //--- Runtime errors (Custom indicators 4601 - 4603) msg_id>4600 && msg_id<4604 ? messages_runtime_custom_indicator[msg_id-4601][m_lang_num] : //--- Runtime errors (Account 4701 - 4758) msg_id>4700 && msg_id<4759 ? messages_runtime_account[msg_id-4701][m_lang_num] : //--- Runtime errors (Indicators 4801 - 4812) msg_id>4800 && msg_id<4813 ? messages_runtime_indicator[msg_id-4801][m_lang_num] : //--- Runtime errors (Market depth 4901 - 4904) msg_id>4900 && msg_id<4905 ? messages_runtime_books[msg_id-4901][m_lang_num] : //--- Runtime errors (File operations 5001 - 5027) msg_id>5000 && msg_id<5028 ? messages_runtime_files[msg_id-5001][m_lang_num] : //--- Runtime errors (Converting strings 5030 - 5044) msg_id>5029 && msg_id<5045 ? messages_runtime_string[msg_id-5030][m_lang_num] : //--- Runtime errors (Working with arrays 5050 - 5063) msg_id>5049 && msg_id<5064 ? messages_runtime_array[msg_id-5050][m_lang_num] : //--- Runtime errors (Working with OpenCL 5100 - 5114) msg_id>5099 && msg_id<5115 ? messages_runtime_opencl[msg_id-5100][m_lang_num] : //--- Runtime errors (Working with databases 5120 - 5130) msg_id>5119 && msg_id<5131 ? messages_runtime_database[msg_id-5120][m_lang_num] : //--- Runtime errors (Working with WebRequest() 5200 - 5203) msg_id>5199 && msg_id<5204 ? messages_runtime_webrequest[msg_id-5200][m_lang_num] : //--- Runtime errors (Working with network (sockets) 5270 - 5275) msg_id>5269 && msg_id<5276 ? messages_runtime_netsocket[msg_id-5270][m_lang_num] : //--- Runtime errors (Custom symbols 5300 - 5310) msg_id>5299 && msg_id<5311 ? messages_runtime_custom_symbol[msg_id-5300][m_lang_num] : //--- Runtime errors (Economic calendar 5400 - 5402) msg_id>5399 && msg_id<5403 ? messages_runtime_calendar[msg_id-5400][m_lang_num] : //--- Runtime errors (Working with databases 5601 - 5626) msg_id>5600 && msg_id<5627 ? messages_runtime_sqlite[msg_id-5601][m_lang_num] : //--- Trade server return codes (10004 - 10045) msg_id>10003 && msg_id<10047 ? messages_ts_ret_code[msg_id-10004][m_lang_num] : #else // MQL4 msg_id>0 && msg_id<10 ? messages_ts_ret_code_mql4[msg_id][m_lang_num] : msg_id>63 && msg_id<66 ? messages_ts_ret_code_mql4[msg_id-54][m_lang_num] : msg_id>127 && msg_id<151 ? messages_ts_ret_code_mql4[msg_id-116][m_lang_num] : msg_id<4000 ? messages_ts_ret_code_mql4[26][m_lang_num] : //--- MQL4 runtime errors (4000 - 4030) msg_id<4031 ? messages_runtime_4000_4030[msg_id-4000][m_lang_num] : //--- MQL4 runtime errors (4050 - 4075) msg_id>4049 && msg_id<4076 ? messages_runtime_4050_4075[msg_id-4050][m_lang_num] : //--- MQL4 runtime errors (4099 - 4112) msg_id>4098 && msg_id<4113 ? messages_runtime_4099_4112[msg_id-4099][m_lang_num] : //--- MQL4 runtime errors (4200 - 4220) msg_id>4199 && msg_id<4221 ? messages_runtime_4200_4220[msg_id-4200][m_lang_num] : //--- MQL4 runtime errors (4250 - 4266) msg_id>4249 && msg_id<4267 ? messages_runtime_4250_4266[msg_id-4250][m_lang_num] : //--- MQL4 runtime errors (5001 - 5029) msg_id>5000 && msg_id<5030 ? messages_runtime_5001_5029[msg_id-5001][m_lang_num] : //--- MQL4 runtime errors (5200 - 5203) msg_id>5199 && msg_id<5204 ? messages_runtime_5200_5203[msg_id-5200][m_lang_num] : #endif //--- Library messages (ERR_USER_ERROR_FIRST) msg_id>ERR_USER_ERROR_FIRST-1 ? messages_library[msg_id-ERR_USER_ERROR_FIRST][m_lang_num] : messages_library[MSG_LIB_SYS_ERROR_CODE_OUT_OF_RANGE-ERR_USER_ERROR_FIRST][m_lang_num] ); } //+------------------------------------------------------------------+
When handling trade server return codes, increase the upper border of the code range by 1, since we now have a new message with the code 10046, which should also be included into the range of handled error codes.
Now the library is able to correctly handle new trade server and runtime error codes. Let's add new properties to the deal object. Now we have the new "Deal fee" property, while StopLoss and TakeProfit properties are now inherent in deals as well. Let's add them to the deal properties as well.
In \MQL5\Include\DoEasy\Defines.mqh, add the new property to the enumeration of order real properties (the library contains the abstract order, while all other content, namely deals and positions, is derived from it):
//+------------------------------------------------------------------+ //| Order, deal, position real properties | //+------------------------------------------------------------------+ enum ENUM_ORDER_PROP_DOUBLE { ORDER_PROP_PRICE_OPEN = ORDER_PROP_INTEGER_TOTAL, // Open price (MQL5 deal price) ORDER_PROP_PRICE_CLOSE, // Close price ORDER_PROP_SL, // StopLoss price ORDER_PROP_TP, // TaleProfit price ORDER_PROP_FEE, // Deal fee (DEAL_FEE from ENUM_DEAL_PROPERTY_DOUBLE) ORDER_PROP_PROFIT, // Profit ORDER_PROP_COMMISSION, // Commission ORDER_PROP_SWAP, // Swap ORDER_PROP_VOLUME, // Volume ORDER_PROP_VOLUME_CURRENT, // Unexecuted volume ORDER_PROP_PROFIT_FULL, // Profit+commission+swap ORDER_PROP_PRICE_STOP_LIMIT, // Limit order price when StopLimit order is activated }; #define ORDER_PROP_DOUBLE_TOTAL (12) // Total number of real properties //+------------------------------------------------------------------+
Increase the total number of real properties from 11 to 12.
Add sorting by the new property to the enumeration of possible order and deal sorting criteria:
//+------------------------------------------------------------------+ //| Possible criteria of sorting orders and deals | //+------------------------------------------------------------------+ #define FIRST_ORD_DBL_PROP (ORDER_PROP_INTEGER_TOTAL-ORDER_PROP_INTEGER_SKIP) #define FIRST_ORD_STR_PROP (ORDER_PROP_INTEGER_TOTAL+ORDER_PROP_DOUBLE_TOTAL-ORDER_PROP_INTEGER_SKIP) enum ENUM_SORT_ORDERS_MODE { //--- Sort by integer properties SORT_BY_ORDER_TICKET = 0, // Sort by an order ticket SORT_BY_ORDER_MAGIC, // Sort by an order magic number SORT_BY_ORDER_TIME_OPEN, // Sort by an order open time in milliseconds SORT_BY_ORDER_TIME_CLOSE, // Sort by an order close time in milliseconds SORT_BY_ORDER_TIME_EXP, // Sort by an order expiration date SORT_BY_ORDER_TYPE_FILLING, // Sort by execution type by remainder SORT_BY_ORDER_TYPE_TIME, // Sort by order lifetime SORT_BY_ORDER_STATUS, // Sort by an order status (market order/pending order/deal/balance and credit operation) SORT_BY_ORDER_TYPE, // Sort by an order type SORT_BY_ORDER_REASON, // Sort by a deal/order/position reason/source SORT_BY_ORDER_STATE, // Sort by an order status SORT_BY_ORDER_POSITION_ID, // Sort by a position ID SORT_BY_ORDER_POSITION_BY_ID, // Sort by an opposite position ID SORT_BY_ORDER_DEAL_ORDER, // Sort by the order a deal is based on SORT_BY_ORDER_DEAL_ENTRY, // Sort by a deal direction – IN, OUT or IN/OUT SORT_BY_ORDER_TIME_UPDATE, // Sort by position change time in seconds SORT_BY_ORDER_TICKET_FROM, // Sort by a parent order ticket SORT_BY_ORDER_TICKET_TO, // Sort by a derived order ticket SORT_BY_ORDER_PROFIT_PT, // Sort by order profit in points SORT_BY_ORDER_CLOSE_BY_SL, // Sort by the flag of closing an order by StopLoss SORT_BY_ORDER_CLOSE_BY_TP, // Sort by the flag of closing an order by TakeProfit SORT_BY_ORDER_MAGIC_ID, // Sort by an order/position "magic number" ID SORT_BY_ORDER_GROUP_ID1, // Sort by the first order/position group ID SORT_BY_ORDER_GROUP_ID2, // Sort by the second order/position group ID SORT_BY_ORDER_PEND_REQ_ID, // Sort by a pending request ID SORT_BY_ORDER_DIRECTION, // Sort by direction (Buy, Sell) //--- Sort by real properties SORT_BY_ORDER_PRICE_OPEN = FIRST_ORD_DBL_PROP, // Sort by open price SORT_BY_ORDER_PRICE_CLOSE, // Sort by close price SORT_BY_ORDER_SL, // Sort by StopLoss price SORT_BY_ORDER_TP, // Sort by TakeProfit price SORT_BY_ORDER_FEE, // Sort by deal fee SORT_BY_ORDER_PROFIT, // Sort by profit SORT_BY_ORDER_COMMISSION, // Sort by commission SORT_BY_ORDER_SWAP, // Sort by swap SORT_BY_ORDER_VOLUME, // Sort by volume SORT_BY_ORDER_VOLUME_CURRENT, // Sort by unexecuted volume SORT_BY_ORDER_PROFIT_FULL, // Sort by profit+commission+swap SORT_BY_ORDER_PRICE_STOP_LIMIT, // Sort by Limit order when StopLimit order is activated //--- Sort by string properties SORT_BY_ORDER_SYMBOL = FIRST_ORD_STR_PROP, // Sort by symbol SORT_BY_ORDER_COMMENT, // Sort by comment SORT_BY_ORDER_COMMENT_EXT, // Sort by custom comment SORT_BY_ORDER_EXT_ID // Sort by order ID in an external trading system }; //+------------------------------------------------------------------+
Now we are able to sort deals by the new property.
In the list of possible mouse states relative to the form, slightly adjust the constant names of the ENUM_MOUSE_FORM_STATE enumeration so that their names indicate the mouse status relative to the form more accurately:
//+------------------------------------------------------------------+ //| The list of possible mouse states relative to the form | //+------------------------------------------------------------------+ enum ENUM_MOUSE_FORM_STATE { MOUSE_FORM_STATE_NONE = 0, // Undefined state //--- Outside the form MOUSE_FORM_STATE_OUTSIDE_FORM_NOT_PRESSED, // The cursor is outside the form, the mouse buttons are not clicked MOUSE_FORM_STATE_OUTSIDE_FORM_PRESSED, // The cursor is outside the form, the mouse button (any) is clicked MOUSE_FORM_STATE_OUTSIDE_FORM_WHEEL, // The cursor is outside the form, the mouse wheel is being scrolled //--- Within the form MOUSE_FORM_STATE_INSIDE_FORM_NOT_PRESSED, // The cursor is inside the form, no mouse buttons are clicked MOUSE_FORM_STATE_INSIDE_FORM_PRESSED, // The cursor is inside the form, the mouse button (any) is clicked MOUSE_FORM_STATE_INSIDE_FORM_WHEEL, // The cursor is inside the form, the mouse wheel is being scrolled //--- Within the window header area MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_NOT_PRESSED, // The cursor is inside the active area, the mouse buttons are not clicked MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_PRESSED, // The cursor is inside the active area, any mouse button is clicked MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_WHEEL, // The cursor is inside the active area, the mouse wheel is being scrolled //--- Within the window scrolling area MOUSE_FORM_STATE_INSIDE_SCROLL_AREA_NOT_PRESSED, // The cursor is within the window scrolling area, the mouse buttons are not clicked MOUSE_FORM_STATE_INSIDE_SCROLL_AREA_PRESSED, // The cursor is within the window scrolling area, the mouse button (any) is clicked MOUSE_FORM_STATE_INSIDE_SCROLL_AREA_WHEEL, // The cursor is within the window scrolling area, the mouse wheel is being scrolled }; //+------------------------------------------------------------------+

In the method returning the StopLoss price, write the StopLoss value for the deal:

If the order status is deal, read the StopLoss value of the deal by its ticket and return the result.

If this is MQL4, the order has no such property — return zero.
In case of MQL5, read the required value from the deal properties by its ticket and return it.
Add handling a new property to the method returning the description of the order real property:
//+------------------------------------------------------------------+ //| Return description of order's real property | //+------------------------------------------------------------------+ string COrder::GetPropertyDescription(ENUM_ORDER_PROP_DOUBLE property) { int dg=(int)::SymbolInfoInteger(this.GetProperty(ORDER_PROP_SYMBOL),SYMBOL_DIGITS); int dgl=(int)DigitsLots(this.GetProperty(ORDER_PROP_SYMBOL)); return ( //--- General properties property==ORDER_PROP_PRICE_CLOSE ?

All other order elements, including balance operations, deals and positions, are derived from the abstract order class. Let's improve the deal object class in \MQL5\Include\DoEasy\Objects\Orders\HistoryDeal.mqh.
Here we need to remove the StopLoss and TakeProfit properties from the list of unsupported properties in the method returning the flag indicating the object support for the real property — now the deal features these two properties and they should be supported by the class object:
//+------------------------------------------------------------------+ //| Return 'true' if an order supports a passed | //| real property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CHistoryDeal::SupportProperty(ENUM_ORDER_PROP_DOUBLE property) { if(property==ORDER_PROP_TP || property==ORDER_PROP_SL || property==ORDER_PROP_PRICE_CLOSE || property==ORDER_PROP_VOLUME_CURRENT || property==ORDER_PROP_PRICE_STOP_LIMIT || ( this.OrderType()==DEAL_TYPE_BALANCE && ( property==ORDER_PROP_PRICE_OPEN || property==ORDER_PROP_COMMISSION || property==ORDER_PROP_SWAP || property==ORDER_PROP_VOLUME ) ) ) return false; return true; } //+------------------------------------------------------------------+
Now the method looks as follows:
//+------------------------------------------------------------------+ //| Return 'true' if an order supports a passed | //| real property, otherwise return 'false' | //+------------------------------------------------------------------+ bool CHistoryDeal::SupportProperty(ENUM_ORDER_PROP_DOUBLE property) { if(property==ORDER_PROP_PRICE_CLOSE || property==ORDER_PROP_VOLUME_CURRENT || property==ORDER_PROP_PRICE_STOP_LIMIT || ( this.OrderType()==DEAL_TYPE_BALANCE && ( property==ORDER_PROP_PRICE_OPEN || property==ORDER_PROP_COMMISSION || property==ORDER_PROP_SWAP || property==ORDER_PROP_VOLUME ) ) ) return false; return true; } //+------------------------------------------------------------------+
Since the method enumerates unsupported properties, the newly added DEAL_FEE property is initially absent from the list meaning we do not need to set it here as it will be supported by default.
All new properties and error codes are added to the library and should be handled correctly.
Now let's move on to dragging form object with the mouse.
Independent handling of form object movement
First of all, we should decide on how to handle the mouse movement event if the button is clicked and held on the form. Considering the previous article experience, we need to develop a slightly different concept of handling mouse events relative to the form. When testing the EA from the previous article I detected multiple shortcomings and incorrect behavior in the mouse interaction with multiple form objects. Therefore, we need another approach.
Multiple experiments proved that the system of flags should be created in the handler of graphical element collection class events. These flags are to indicate a form object the mouse cursor is currently located at, whether the mouse button is pressed at the moment and whether it was pressed outside all forms present on the chart. The form object features the flag of interaction with the environment. Use it to specify the form you want to work with and whose events you want to handle.
In other words, the concept should be as follows:
- If the cursor is outside all forms present on the chart, the context menu is allowed for the chart, as well as dragging it with the mouse and using the Crosshair tool, while there should be no response when the cursor touches the forms (with the mouse button pressed outside the forms) as we drag the chart with the mouse.
- As soon as the mouse cursor hovers over any form object (with the button released), disable all chart tools and wait for the mouse button being pressed on the form or for any other interaction of the mouse with the form (for example, mouse wheel scrolling or visualization of the cursor hovering above the form as several visual form effects).
- If the mouse button is pressed on the form, the interaction and movement flag is set for the form. The interaction flag is then to be used for defining which of the two forms should be selected provided that these two forms are superimposed, the mouse cursor hovers over them and the mouse button is pressed afterwards. The form with the active interaction flag should be selected.
If we release the button after dragging the form with the mouse, the chart tools are enabled while the form interaction flag remains active. Thus, this form is selected out of the two if they are superimposed again and the mouse button is released. If the cursor selects a currently inactive form (not the one that has just been dragged) and starts dragging it, the interaction flag is removed from the first form and activated for the selected one.
Such flag system will always let us know which form was last active, which form has the cursor hovering above it and whether it can be visually highlighted (these handlers will be implemented later in the form object class rather than in the graphical element collection class). We will always be able to interact with a form featuring the cursor above it and drag a form which was last selected by the mouse.
We need to remove everything that was created in the form object class events handler (except for adjusting form coordinates in case of a chart change event). Open \MQL5\Include\DoEasy\Objects\Graph\Form.mqh and remove the redundant code from the handler leaving the adjustment of the vertical coordinate shift:
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CForm::OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam) { //--- Adjust subwindow Y shift CGCnvElement::OnChartEvent(id,lparam,dparam,sparam); } //+------------------------------------------------------------------+
Besides, I have corrected the enumeration constant names to make them more comprehensible:
//+------------------------------------------------------------------+ //| Return the mouse status relative to the form | //+------------------------------------------------------------------+ ENUM_MOUSE_FORM_STATE CForm::MouseFormState(const int id,const long lparam,const double dparam,const string sparam) { //--- Get the mouse status relative to the form, as well as the states of mouse buttons and Shift/Ctrl keys ENUM_MOUSE_FORM_STATE form_state=MOUSE_FORM_STATE_OUTSIDE_FORM_NOT_PRESSED; ENUM_MOUSE_BUTT_KEY_STATE state=this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam); //--- Get the mouse status flags from the CMouseState class object and save them in the variable this.m_mouse_state_flags=this.m_mouse.GetMouseFlags(); //--- If the cursor is inside the form if(CGCnvElement::CursorInsideElement(m_mouse.CoordX(),m_mouse.CoordY())) { //--- Set bit 8 responsible for the "cursor inside the form" flag this.m_mouse_state_flags |= (0x0001<<8); //--- If the cursor is inside the active area, set bit 9 "cursor inside the active area" if(CGCnvElement::CursorInsideActiveArea(m_mouse.CoordX(),m_mouse.CoordY())) this.m_mouse_state_flags |= (0x0001<<9); //--- otherwise, release the bit "cursor inside the active area" else this.m_mouse_state_flags &=0xFDFF; //--- If one of the mouse buttons is clicked, check the cursor location in the active area and //--- return the appropriate value of the pressed key (in the active area or the form area) if((this.m_mouse_state_flags & 0x0001)!=0 || (this.m_mouse_state_flags & 0x0002)!=0 || (this.m_mouse_state_flags & 0x0010)!=0) form_state=((this.m_mouse_state_flags & 0x0200)!=0 ? MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_PRESSED : MOUSE_FORM_STATE_INSIDE_FORM_PRESSED); //--- otherwise, if not a single mouse button is pressed else { //--- if the mouse wheel is scrolled, return the appropriate wheel scrolling value (in the active area or the form area) if((this.m_mouse_state_flags & 0x0080)!=0) form_state=((this.m_mouse_state_flags & 0x0200)!=0 ? MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_WHEEL : MOUSE_FORM_STATE_INSIDE_FORM_WHEEL); //--- otherwise, return the appropriate value of the unpressed key (in the active area or the form area) else form_state=((this.m_mouse_state_flags & 0x0200)!=0 ? MOUSE_FORM_STATE_INSIDE_ACTIVE_AREA_NOT_PRESSED : MOUSE_FORM_STATE_INSIDE_FORM_NOT_PRESSED); } } //--- If the cursor is outside the form else { //--- return the appropriate button value in an inactive area form_state= ( ((this.m_mouse_state_flags & 0x0001)!=0 || (this.m_mouse_state_flags & 0x0002)!=0 || (this.m_mouse_state_flags & 0x0010)!=0) ? MOUSE_FORM_STATE_OUTSIDE_FORM_PRESSED : MOUSE_FORM_STATE_OUTSIDE_FORM_NOT_PRESSED ); } return form_state; } //+------------------------------------------------------------------+
All is set. Now we need to create the flag system in the graphical element collection class event handler.

In the private section of the class, declare the "Mouse status" class object and two methods — the one returning the pointer to the form located under the cursor and the one resetting all interaction flags for all forms except the specified one:

The method returning the pointer to the form located under the cursor:
//+------------------------------------------------------------------+ //| Return the pointer to the form located under the cursor | //+------------------------------------------------------------------+ CForm *CGraphElementsCollection::GetFormUnderCursor(const int id, const long &lparam, const double &dparam, const string &sparam,ENUM_MOUSE_FORM_STATE &mouse_state) { //--- Initialize the mouse status relative to the form mouse_state=MOUSE_FORM_STATE_NONE; //--- Declare the pointers to graphical element collection class objects CGCnvElement *elm=NULL; CForm *form=NULL; //--- Get the list of objects the interaction flag is set for (there should be only one object) CArrayObj *list=CSelect::ByGraphCanvElementProperty(GetListCanvElm(),CANV_ELEMENT_PROP_INTERACTION,true,EQUAL); //--- If managed to obtain the list and it is not empty if(list!=NULL && list.Total()>0) { //--- Get the only graphical element there elm=list.At(0); //--- If it is a form object if(elm.TypeGraphElement()==GRAPH_ELEMENT_TYPE_FORM) { //--- Assign the pointer to the element for the form object pointer form=elm; //--- Get the mouse status relative to the form mouse_state=form.MouseFormState(id,lparam,dparam,sparam); //--- If the cursor is within the form, return the pointer to the form if(mouse_state>MOUSE_FORM_STATE_OUTSIDE_FORM_WHEEL) return form; } } //--- If there is no a single form object with a specified interaction flag, //--- in the loop by all graphical element collection class objects int total=this.m_list_all_canv_elm_obj.Total(); for(int i=0;i<total;i++) { //--- get the next element elm=this.m_list_all_canv_elm_obj.At(i); if(elm==NULL) continue; //--- if the obtained element is a form object if(elm.TypeGraphElement()==GRAPH_ELEMENT_TYPE_FORM) { //--- Assign the pointer to the element for the form object pointer form=elm; //--- Get the mouse status relative to the form mouse_state=form.MouseFormState(id,lparam,dparam,sparam); //--- If the cursor is within the form, return the pointer to the form if(mouse_state>MOUSE_FORM_STATE_OUTSIDE_FORM_WHEEL) return form; } } //--- Nothing is found - return NULL return NULL; } //+------------------------------------------------------------------+
The method is commented in detail in the code. In brief, we need to know which form object the mouse cursor is located at. If we simply have a look at the cursor coordinates and compare them with the form coordinates and size, we will surely find the form, above which the cursor is located. However, here we face an issue: if two forms are superimposed, the form coming first in the list is selected, rather than the one located above all others on the chart, which is wrong. Therefore, clicking the mouse button on the form sets the appropriate interaction flag used to find the active form. Only if such form is absent, we start searching any listed form, above which the mouse cursor is located. Such an approach provides us with the correct behavior when handling the mouse. The form that was last active is always selected. This is the form located above all others on the chart — i.e. on the foreground, since the form is moved to the foreground immediately after its selection.
The method resetting interaction flags for all forms except the specified one:
//+--------------------------------------------------------------------+ //| Reset all interaction flags for all forms except the specified one | //+--------------------------------------------------------------------+ void CGraphElementsCollection::ResetAllInteractionExeptOne(CForm *form_exept) { //--- In the loop by all graphical element collection class objects int total=this.m_list_all_canv_elm_obj.Total(); for(int i=0;i<total;i++) { //--- get the pointer to a form object CForm *form=this.m_list_all_canv_elm_obj.At(i); //--- if failed to receive the pointer, or it is not a form, or it is not a form whose pointer has been passed to the method, move on if(form==NULL || form.TypeGraphElement()!=GRAPH_ELEMENT_TYPE_FORM || (form.Name()==form_exept.Name() && form.ChartID()==form_exept.ChartID())) continue; //--- Reset the interaction flag for the current form in the loop form.SetInteraction(false); } } //+------------------------------------------------------------------+
With this method, we will always have only one form with the active interaction flag at a time. When selecting a form with the mouse, we immediately set the interaction flag for it. For all other forms, the flag should be disabled. This is done when calling the method.
We should call the handlers of events of mouse interaction with the forms in the handler of graphical element collection class events in case of any events except for the chart change event. The code segment immediately following the chart change event check is the most suitable for that as we need to respond to all events except for this one. Let's place the block of handlers of mouse interaction with the forms where it is necessary:
//+------------------------------------------------------------------+ //| Event handler | //+------------------------------------------------------------------+ void CGraphElementsCollection::OnChartEvent(const int id, const long &lparam, const double &dparam, const string &sparam) { CGStdGraphObj *obj_std=NULL; // Pointer to the standard graphical object CGCnvElement *obj_cnv=NULL; // Pointer to the graphical element object on canvas ushort idx=ushort(id-CHARTEVENT_CUSTOM); if(id==CHARTEVENT_OBJECT_CHANGE || id==CHARTEVENT_OBJECT_DRAG || id==CHARTEVENT_OBJECT_CLICK || idx==CHARTEVENT_OBJECT_CHANGE || idx==CHARTEVENT_OBJECT_DRAG || idx==CHARTEVENT_OBJECT_CLICK) { //--- Calculate the chart ID //--- If the event ID corresponds to an event from the current chart, the chart ID is received from ChartID //--- If the event ID corresponds to a user event, the chart ID is received from lparam //--- Otherwise, the chart ID is assigned to -1 long param=(id==CHARTEVENT_OBJECT_CLICK ? ::ChartID() : idx==CHARTEVENT_OBJECT_CLICK ? lparam : WRONG_VALUE); long chart_id=(param==WRONG_VALUE ? (lparam==0 ? ::ChartID() : lparam) : param); //--- Get the object, whose properties were changed or which was relocated, //--- from the collection list by its name set in sparam obj_std=this.GetStdGraphObject(sparam,chart_id); //--- If failed to get the object by its name, it is not on the list, //--- which means its name has been changed if(obj_std==NULL) { //--- Let's search the list for the object that is not on the chart obj_std=this.FindMissingObj(chart_id); //--- If failed to find the object here as well, exit if(obj_std==NULL) return; //--- Get the name of the renamed graphical object on the chart, which is not in the collection list string name_new=this.FindExtraObj(chart_id); //--- set a new name for the collection list object, which does not correspond to any graphical object on the chart, //--- and send an event with the new name of the object to the control program chart if(obj_std.SetNamePrev(obj_std.Name()) && obj_std.SetName(name_new)) ::EventChartCustom(this.m_chart_id_main,GRAPH_OBJ_EVENT_RENAME,obj_std.ChartID(),obj_std.TimeCreate(),obj_std.Name()); } //--- Update the properties of the obtained object //--- and check their change obj_std.PropertiesRefresh(); obj_std.PropertiesCheckChanged(); } //--- Handle standard graphical object events in the collection list for(int i=0;i<this.m_list_all_graph_obj.Total();i++) { //--- Get the next graphical object and obj_std=this.m_list_all_graph_obj.At(i); if(obj_std==NULL) continue; //--- call its event handler obj_std.OnChartEvent((id<CHARTEVENT_CUSTOM ? id : idx),lparam,dparam,sparam); } //--- Handle chart changes for extended standard objects if(id==CHARTEVENT_CHART_CHANGE || idx==CHARTEVENT_CHART_CHANGE) { CArrayObj *list=this.GetListStdGraphObjectExt(); if(list!=NULL) { for(int i=0;i<list.Total();i++) { obj_std=list.At(i); if(obj_std==NULL) continue; obj_std.OnChartEvent(CHARTEVENT_CHART_CHANGE,lparam,dparam,sparam); } } } //--- Handling mouse events of graphical objects on canvas //--- If the event is not a chart change else { //--- Check whether the mouse button is pressed bool pressed=(this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam)==MOUSE_BUTT_KEY_STATE_LEFT ? true : false); ENUM_MOUSE_FORM_STATE mouse_state=MOUSE_FORM_STATE_NONE; //--- Declare static variables for the active form and status flags static CForm *form=NULL; static bool pressed_chart=false; static bool pressed_form=false; static bool move=false; //--- If the button is not pressed on the chart and the movement flag is not set, get the form, above which the cursor is located if(!pressed_chart && !move) form=this.GetFormUnderCursor(id,lparam,dparam,sparam,mouse_state); //--- If the button is not pressed, reset all flags and enable the chart tools if(!pressed) { pressed_chart=false; pressed_form=false; move=false; SetChartTools(::ChartID(),true); } //--- If this is a mouse movement event and the movement flag is active, move the form, above which the cursor is located (if the pointer to it is valid) if(id==CHARTEVENT_MOUSE_MOVE && move) { if(form!=NULL) { //--- calculate the cursor movement relative to the form coordinate origin int x=this.m_mouse.CoordX()-form.OffsetX(); int y=this.m_mouse.CoordY()-form.OffsetY(); //--- get the width and height of the chart the form is located at int chart_width=(int)::ChartGetInteger(form.ChartID(),CHART_WIDTH_IN_PIXELS,form.SubWindow()); int chart_height=(int)::ChartGetInteger(form.ChartID(),CHART_HEIGHT_IN_PIXELS,form.SubWindow()); //--- Adjust the calculated form coordinates if the form is out of the chart range if(x<0) x=0; if(x>chart_width-form.Width()) x=chart_width-form.Width(); if(y<0) y=0; if(y>chart_height-form.Height()) y=chart_height-form.Height(); //--- Move the form by the obtained coordinates form.Move(x,y,true); } } //--- Display debugging comments on the chart Comment ( (form!=NULL ? form.Name()+":" : ""),"\n", EnumToString((ENUM_CHART_EVENT)id),"\n", EnumToString(this.m_mouse.ButtonKeyState(id,lparam,dparam,sparam)), "\n",EnumToString(mouse_state), "\npressed=",pressed,", move=",move,(form!=NULL ?

The entire code block of the 'mouse interacting with the form' event handler is accompanied by detailed comments. Currently, some events have only "stubs" — these blocks are to contain calling event handlers in a form object.
At the moment, all is ready for testing the new concept.
Test
To perform the test, let's use the EA from the previous article and save it to \MQL5\Experts\TestDoEasy\Part97\ as TestDoEasyPart97.mq5.
There will be almost no changes. I will only adjust the coordinates of created forms. I will use the previously created macro substitution specifying the number of created form objects:

Compile the EA and launch it on the chart:
I have eliminated all drawbacks mentioned after testing the EA from the previous article. Besides, moving forms is limited by the chart borders. When one form is superimposed on another, the necessary form is always selected and the cursor coordinate shifts relative to the moved form coordinates are always calculated correctly.
What's next?
In the next article, I will continue the development of library graphical objects.
All files of the current library version, test EA and chart event control indicator for MQL5 are attached below for you to test and download. Leave your questions, comments and suggestions in the comments.
