In this article we will see how we can get the top-level changed signal 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). This signal is emitted when the floating property changes.

topLevelChangedmethod with the dock widget object.
Syntax : dock.topLevelChanged.connect(method)
Argument : It takes method as argument
Return : It returns None
Below is the implementation
