[macgayver]

Hello everyone, this is my first post and I am starting at qt,
and when I'm with a doubt in my project, does not appear in a SIGNAL MainWindow class to the event to open the form or close to it. Can anyone help me?

Signals, no.
Events, yes.

Use the functions close() and show() to close and show the main window.
React to the closeEvent and showEvent to do other stuff.
