MainWindow disappearing when loading a QMessageBox

Yes, probably an access violation.
Do you get any runtime debug warning messages from connect?
Try running the debug version from a console.

No, no... it quits correctly!

Maybe that since I first created the main window through the designer the exit button I'm using has got some particular characteristics?

Yes, it might be connected to some slot that closes the window.

It is! I was missing a line in the .h file generated via Qt Designer/UIC, which was implementing exactly what you said. I removed that line and now everything works smoothly. and as expected.

Thank you very much to all of you!

Cheers,

Don't remove any lines from autogenerated code or the problem will come back. Better fix the .ui file.

Sure, Jacek. I've used the Qt Designer only at the beginning in order to create the skeleton of the main windows. Now I don't generate the .h file automatically, but I simply use a progressively modified version of it.

That's an interesting way to use Designer..

Probably not the most intelligent, I know... but it's so handy...
