How to block signals on QMainWindow?
In QMainWindow i opening QDialogBox, after opening it, QMainWindow still procesess signal. What should i do to block it?
Just remember to unblock it later.
Or set the QDialogBox as a model dialog, this will block GUI inputs to the MainWindow if you prefer to keep the mainwindow 'running' in the background e.g. updates of the statusbar etc.
Is your dialog modal ? Are you showing it using exec ?
