 |
|
I have a SDI application that contains multiple forms. When I
minimize the main form, all secondary forms get automatically
minimized. Is there a way to keep uncouple the secondary forms from
the main form such that they stay open?
Each seconday form is auto created and shown via:
SecondaryFormX->Show();
I've also tried to not autocreate the form and manually create it
via
TSecondaryFormX *form=new TSecondaryFormX(MainForm);
form->Parent=MainForm;
form->Show();
Thanks in advance for your help.

Yes. That is completely normal.

Yes. Choose another mainform. That can be an empty TForm. Place it 'out of sight'
at startup. For instance. Left = Screen->Width; would do.

It is autocreated in WinMain ? They are set Invisible at designtime
and made visible with Show().

Why are you asigning a Parent ? Now even if the Parent is not
the MainForm such children will minimize if the Parentwindow
minimizes.

Yes but it means that each secondary form will have it's own
icon on the task bar. All you have to do is apply the
WS_EX_APPWINDOW flag to the Form's ExStyle and assign the
desktop as the parent. This is accomplished by overriding the
form's CreateParams method:
//--- in the header -------------------------------------------
protected:
virtual void __fastcall CreateParams( TCreateParams &Params );
//--- in the unit ---------------------------------------------
void __fastcall TForm1::CreateParams(TCreateParams &Params)
{
TForm::CreateParams( Params );
Params.ExStyle |= WS_EX_APPWINDOW;
Params.WndParent = GetDesktopWindow();
}

Or just simply set the Application->ShowMainForm property to false before
Application->Run() is called.
