Making Qwidget Transparent on VideoWidget

Question

I have a QWidget which should take place over the central widget of my application which is a VideoWidget for playing video. The problem is that I can't set background of the QWidget to be transparent.

Answer 1

Use a StyleSheet (you can do that in code with setStylesheet or in the ui file : RMB on the widget you want "Change stylesheet" or even in the properties tab)

for instance

"background-color: rgba(255, 255, 0, 50);"

gives a yellow transparant look:(example of a button used on top of another button)

With stylesheets you can control the look of a complete program or just the specific widgets you want. More info in the style sheet reference

Answer 2

You could make the full Widget invisible:

QWidget::setHidden(true);
