How to calculate CAppDialog Minimize or Maximize status?

[Somsri Sarkar]

Greetings Members,

I have a question. How to get the minimized or maximized state status of the CAppDialog? Need to programmatically figure out whether the current window is in minimize state or in maximize state.

Tried following way with global variable:

int minimized_status = 0;

//---Custom function---
class CAppDialogExample : public CAppDialog
  {
public:
   //--- chart event handler
   virtual bool      OnEvent(const int id,const long &lparam,const double &dparam,const string &sparam);
private:
   void              OnClickButtonMinMax(){if(minimized_status == 0) minimized_status = 1; else minimized_status = 0;}
  };
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
EVENT_MAP_BEGIN(CAppDialogExample)
EVENT_MAP_END(CAppDialog)

It does change the minimized_status value on each click. But the problem is CAppDialog is no longer getting minimized after using this code.

Any easy method?
Thank you
Regards

Thank you for your reply. Unfortunately, have tried it, no change. On clicking the minimize button its only changing the icon, main window is not minimizing with the custom function.

void OnClickButtonMinMax(){
if(minimized_status == 0) {minimized_status = 1;main_window.Minimized(true);} 
else {minimized_status = 0;main_window.Minimized(false);}
}

Seems like custom function code has some issue, but unable to detect.

That’s not what you asked. You wanted to determine the status

You will need to post your code to get an answer for your issue

CAppDialog has that property by default (m_minimized):

   void              Minimized(const bool flag) { m_minimized=flag; }

 Also you need to use the Minimize Maximize methods instead of Minimize(true | false)

void OnClickButtonMinMax(){
if(minimized_status == 0) {minimized_status = 1;main_window.Minimize();} 
else {minimized_status = 0;main_window.Maximize();}
}

Thank you so much! That just worked perfectly.  Learned a new thing.
