PyQt5 QComboBox – Checking if mouse tracking is activated or not

In this article we will see how we can check if the mouse tracking of the combo box is activated or not, combo box receive signal about the mouse when any button is pressed but after mouse tracking it will receive all the signals about the mouse even if any button is not pressed. By default this property is False although we can activate mouse tracking with the help of setMouseTracking method.

In order to do this we use hasMouseTracking method

Syntax : combo_box.hasMouseTracking()

Argument : It takes no argument

Return : It returns bool



Below is the implementation
