PyQt5 QDockWidget – Getting Style Sheet

In this article we will see how we can get style sheet of the QDockWidget. QDockWidget provides the concept of dock widgets, also know as tool palettes or utility windows. Dock windows are secondary windows placed in the dock widget area around the central widget in a QMainWindow(original window). Style sheet represents the style i.e look of the widget it consists of color, spacing, padding, border features. It can be set with the help of setStyleSheet method.

In order to do this we will use styleSheet method with the dock widget object.

Syntax : dock.styleSheet()

Argument : It takes no argument

Return : It returns string
