Why when I close QDialog my main application gets killed?

[alex chpenst]

Hi,
I have a dialog that is started from a context menu of my application. The problem is that when I close the dialog, my application closes as well. How do I make a dialog such that the main application stays running when the dialog is closed? (I open the dialog with a parent widget=0. MyDialog inherits QDialog. My main application is a tray icon on the panel with a context menu).

Thanks a lot!
Alex.

MainApplication::MainApplication()
 {
     ...
     myDialog = 0;
 }
 
 void MainApplication:: openDialog() {
     if (!myDialog) 
       myDialog = new MyDialog;
 
     myDialog->show();
 }

MainApplication::MainApplication()
 {
     ...
     myDialog = 0;
 }

 void MainApplication:: openDialog() {
     if (!myDialog) 
       myDialog = new MyDialog;
     
     myDialog->show();
 }

To copy to clipboard, switch view to plain text mode

Set QApplication::quitOnLastWindowClosed property to false.
