In this article we will see how we can set window opacity property to the QScrollBar. QScrollBar is a control that enables the user to access parts of a document that is larger than the widget used to display it. Slider is the scroll-able object inside the bar. This property holds the level of opacity for the window. The valid range of opacity is from 1.0 (completely opaque) to 0.0 (completely transparent).
Note : On X11 you need to have a composite manager running, and the X11 specific _NET_WM_WINDOW_OPACITY atom needs to be supported by the window manager you are using.
In order to do this we will use
setWindowOpacitymethod with the scroll bar object.
Syntax : scroll.setWindowOpacity(n)
Argument : It takes float as argument
Return : It returns None
Below is the implementation
