 ## About
 
-The widget functions exactly like PyQt's regular QPushButton with the only exception being the way methods are connected to the clicked event. Normally you would connect a method to the `clicked` event by using the `connect()` method. On this button you use the `setAction()` method instead, passing a callable object as its parameter the same way you would do with the `connect()` method. The method will then get executed in a `QThread`, allowing the button to display a loading animation.
