By the way, who knows how to make that when you click on the button, it would be squeezed if the LKM is pressed and released if the LKM is released?
and what would press the button to click and release and what would release the button to click and release, nonsense)
ZS: of course you can change a property right after you release the LKM, but is that how it's done? )

Yes. You'll have to control object's state yourself, if you want to do it your own way. )
all would be fine, but the button is not pressed when the LKM is pressed, and pressed only when the LKM is released, nonsense )
ZS: want to press the button? let it go )
But if you do otherwise, given thatOnChartEvent does not work in the tester, then in general, no way in the tester with the copies of copies can not work.

With the tester, many things don't work yet. Remains to write in servicedesk and then follow updates. )
And outside the tester, you have to write your own handlers for the controls to work the way you want them to.

OnChartEvent() handles typical and user events. As far as custom events are concerned this handler in the Tester works!!! See my article Prescriptions in MQL5 - Handling Custom Chart EventsThere is a CustomEventProcessor robot there. It trades in the Tester.
Tester's trouble - it's graphics... I wrote earlier to Service Desk about graphics, so far only promises...

The trouble with the tester is the graphics... I've written to Service Desk before about graphics, only promisesso far ...
The situation is as follows: I create an OBJ_TEXT object on the chart. Then I manually delete this OBJ_TEXT from the chart. Then I try to find the deleted object on the chart and get an error (this is logical: the object was deleted, so it cannot be found). Then I try to move the anchor point of the deleted OBJ_TEXT object with ObjectMove, but get no error.
Question: should ObjectMove give an error when trying to move the anchor point of a deleted OBJ_TEXT?
Please advise who knows: when trying to display an indicator in the visualiser (tester), a 4014 error appears, although no such error occurs when running the same code in the terminal window.
The code is as follows:
Indic_Handle[Indic_Total-1]=iMA(NULL,0,MA_Period,MA_Shift,MODE_LWMA,PRICE_CLOSE);
if(Indic_Handle[Indic_Total-1]==INVALID_HANDLE)
{Error_Message;return(false);}
if(F_If_Indic_Exist(Indic_Handle[Indic_Total-1])==false) // Проверяем есть ли уже индикатор с таким хендлом. Если нет - добавлем новый индикатор
if(ChartIndicatorAdd(0,0,Indic_Handle[Indic_Total-1])==false)
{Error_Message;return(false);}
The "Error_Message" command is defined by a macro:
#define Error_Message_Exp Alert(__FILE__+": "+__FUNCTION__+": Error at line "+(string)__LINE__+". Last Error code: "+(string)GetLastError())
When executed in the terminal: The code works as it should, without errors. The indicator is plotted on the chart, the"Indic_Handle[Indic_Total-1]" variable is assigned a handle value.
But when executed in the tester and/or in the visualizer. An error is printed to the log:
2014.12.15 21:16:10 Core 1 2014.01.01 00:00:00 Alert: GA_Incl.mqh: F_Offspr_Init: Error at line 149. Last Error code: 4014
(line "149" - is the"{Error_Message;return(false);}" line under line "148":"if(ChartIndicatorAdd(0,0,Indic_Handle[Indic_Total-1])==false)".
The error obviously occurs when executing the "ChartIndicatorAdd" function which is executed differently in the tester environment and the terminal environment.
The decoding of the error code does not make it clear:
ERR_FUNCTION_NOT_ALLOWED
4014
The system function is not allowed to be called
On the forum I found a mention of this error occurring in the same situation by another user, but his question remains unanswered. (https://www.mql5.com/ru/forum/1111/page763#comment_208678)
I have found out that if I continue to run the program in the tester despite the error, the required indicator will be applied to the chart. But the indicator handle does not correspond to the value in theIndic_Handle[Indic_Total-1] variable.(But the indicator itself is created after some ticks, after calling the ChartIndicatorAdd command.
Please help me
Thank you.
Right, it doesn't print. But it works. Try tracking the event with graphics.
