When using QAbstractButton::setIcon(), the icon on the button is smaller than expected. Even if QAbstractButton::setIconSize() with big sizes is used, the icon may even get smaller. One thing that is very notable is that there is always very much padding between icon and outer border of the button. The icon should have less padding than the text.

See the attached screen shot and test app.
