closing dialog in hidden main Widget

Hi all,
I noticed a strange beahaviour when closing a modal dialog(but the same is for any kind of widget) child
of a hidden main widget, what happens is that if the main widget is hidden and I close the modal dialog the application quit.
This case occurs to me when my application is iconized in the tray icon, so it's hidden, and I close a custom "About" dialog,
The problem doesn't happen if the main window is visible or shown minimized.

Is there a way to bypass this behaviour?
thanks in advance

bye

You experience that behaviour because by default QApplication quits when the last window is closed. To avoid that you need to call QApplication::setQuitOnLastWindowClosed(false).

thanks a lot, easier than I thought
bye

Just remember you'll have to call QCoreApplication::quit() yourself now.
