qt button maximize

I would like to animate a widget (QPushButon) to move across my application screen. For that I create a new button and using the QPropertyAnimation class and the property "geometry" of the button, I move it from top to down. The problem is that the button comes with the close, minimize, maximize buttons, etc. I don't want them to be there, nor the border that comes with the widget. What should I do ?

You want to use the function QWidget::setWindowFlags( Qt::WindowFlags ).

If you want to remove the maximize/minimize/close buttons, this should work for you:

setWindowFlags( Qt::CustomizeWindowHint );

Qt::CustomizeWindowHint turns off all the default window hints, like the maximize, minimize, close buttons, and the title bar.

Here's a list of all Qt::WindowFlags.
