The
CWndContainer::AddToElementsArray(m_subwin, _MyEditBox);does not work in this case...

Is the CComboBox a static object. Is it possible to modify the list of elements in the
ComboBox-Listview after the creation of the ComboBox?
Thank you!
HI , if I roll up the Dialog, and change the period.the Dialog is not ok.in MT4.
I am trying to add an input field to a tab but it wont work.
input double whenToTrail=10.3; class CProgram: public CWndEvents { protected: CSpinEdit m_StartTS; //Code protected: bool CreatetrailStop(const int x_gap, const int y_gap, const string text); };
then the function.
bool CProgram::CreatetrailStop(const int x_gap, const int y_gap, string text) { //--- Save the pointer to the main element m_StartTS.WindowPointer(m_window); //--- Coordinates int x = m_window.X() + x_gap; int y = m_window.Y() + y_gap; //--- Reserve for the tab m_tabs.AddToElementsArray(1, m_StartTS); //--- Properties m_StartTS.XSize(95); m_StartTS.YSize(15); m_StartTS.EditXSize(40); m_StartTS.MinValue(0.01); m_StartTS.StepValue(0.01); m_StartTS.SetDigits(1); m_StartTS.SetValue(NormalizeDouble(whenToTrail,1)); m_StartTS.ResetMode(true); //--- Create a control if(!m_StartTS.CreateSpinEdit(m_chart_id, m_subwin, text, x, y)) return(false); //--- Add the object to the common array of object groups CWndContainer::AddToElementsArray(0, m_StartTS); return(true); }
this object isn't attached to the Panel but is on thee chart.
and after deleting the chart the object remains
Hi, this article interests me a lot, I tried to install it but when I compile it it gives me these errors:

How can I add CLabel to tabs, when I create CLabel item and want add to tabs compiler gives me these error:
CLabel m_overview_titlte_label; bool CMainPanel::CreateOverviewTitleLabel(const string text) { //--- Pass the panel object m_overview_title_label.WindowPointer(m_window); //--- Attach to the fourth tab of the first group of tabs m_main_panel_tabs.AddToElementsArray(0,m_overview_title_label); m_main_panel_tabs.AddToElementsArray( //--- Coordinates int x=m_window.X()+OVERVIE_TITLE_LABEL_GAP_X; int y=m_window.Y()+OVERVIE_TITLE_LABEL_GAP_Y; //--- Set properties before creation m_overview_title_label.XSize(140); m_overview_title_label.YSize(18); //m_overview_title_label. //--- Create control if(!m_overview_title_label.Create(m_chart_id,text,m_subwin,x,y)) return(false); //--- Add the object to the common array of object groups //CWndContainer::AddToElementsArray(0,m_overview_title_label); return(true); }

I had same problem, I solve that by create a include file and write my label class and use that. You must create this file in Include\EasyAndFastGUI\Controls\MyLabel.mqh

New article Graphical Interfaces VII: The Tabs Control (Chapter 2) has been published:
The first chapter of seventh part introduced three classes of controls for creating tables: text label table (CLabelsTable), edit box table (CTable) and rendered table (CCanvasTable). In this article (chapter two) we are going to consider the Tabs control.
Tabs are used to control the display of predefined sets of graphical interface controls. Often, multi-functional applications require a large number of controls to be fit into a confined space allocated for the graphical interface. Tabs can be used to group the controls by categories and to display only the currently needed group. This makes the interface much more accessible and more intuitive for the end user. On the surface, the tabs look like a group of buttons with labels (name of the controls group). At the same time, only one of them can be selected (active).
Let us enumerate all components of this control.
Fig. 1. Components of the Tabs control.
Let us create four modes to position the tabs relative to the area, where other controls will be placed: top, bottom, left and right.
