I have two simple windows one with a pushbutton and the other with a widget-Label to display a message, what I want is q pressing the pushbutton Window Button a message is displayed in another window called Mnesaje like I can do this ?
Please, take a look at Qt's documentation chapter about "Signals and Slots" it's all explained there. There's also a lot of examples that you can follow as well as posts on this forum with the same question.
