PyQt5 QCommandLinkButton – Checking if it is Checkable
  • Last Updated : 26 Jun, 2020

In this article we will see how we can check if the QCommandLinkButton is checkable or not, by default it is not checkable although we can make it checkable any time with the help of setCheckable method, checkable command link button when clicked remain in the pressed state and when clicked again it comes back to original state.

In order to do this we use isCheckable method with the command link button object

Syntax : button.isCheckable()

Argument : It takes no argument

Return : It returns bool



Below is the implementation
