How to block The rest of the GUI like QMessageBox

[oswalidos]

Hello,

I want to take the same functionality of QmessageBox, I have a Qwidget that contain a button, when i click on the button it open another QWidget, the new opened widget must block the main widget.

I think it's common after some hour of googling i still can't find out how to do that,

Thanks in advance.

Make that new widget a QDialog and call QDialog::exec() instead of show().
