                Hackishly turns an empty button into a big button, with a large
415
 
                padding.
416
 
 
417
 
                I tried to set the padding throught style.qss, but it also
418
 
                applies padding between the image and the text, which looks
419
 
                ugly.  This hackish code creates two QLabel inside the button
420
 
                and lay them out vertically. This makes it possible to define
421
 
                proper padding with setContentsMargins().
422
 
 
423
 
                It returns the text label so that its text can be updated when
424
