Forcing QDialog to stay open

How should I best go about forcing a QDialog to stay open when the dialog's accept() slot is called? I was thinking of reimplementing that function to get the dialog's exec to return without hiding the dialog, but was wondering if there were any better ways to accomplish this.

You need to make your QDialog modeless, by calling show instead of exec, and using a custom signal instead of accept, because accept closes the window. And you connect that signal to a slot in the main window with the code you had after the exec call.

And in case that wasn't already the case, you should keep a reference/pointer to your QDialog somewhere (as a member in your main window class, or a static variable within the function that opens it) to be able to avoid creating multiple instances of the dialog, and you need to make sure you only connect the signals/slots once.

Rather than use a QDialog, I would accomplish the effect with a QDockWidget.

  • Remove the feature that allows the dock to be moved (QDockWidget::DockWidgetMovable)
  • Set the dock widget to floating (setFloating(true))
  • Connect items on the dock widget to the appropriate signals and slots on the main window
