PyQt - Transparent Background

Question

I am trying to make the background of my window transparent. But under the widgets that are on it, I see parts of my desktop. Now I have this in the constructor:

    self.setFocusPolicy(Qt.StrongFocus)
    self.setAttribute(Qt.WA_QuitOnClose,True)

    self.setBackgroundRole(QtGui.QPalette.Base)
    self.setAttribute(Qt.WA_NoSystemBackground)

Answer 1

In response to gs, this faq explains why (before Qt 4.5) you cannot achieve this:

There is no direct support for partial transparency, where the window is transparent and the widgets on it are not in Qt.

Answer 3

Try this for your widgets:

widget.setAutoFillBackground(True)

I think you could also install it in Qt Designer.
