How to change QPushButton icon/text spacing with stylesheets?

Question

I'm fairly new to Qt's method of stylesheets and I am looking to adjust the spacing between the icon and text on a QPushButton.

This is the gap I'm referring to: http://imageshack.us/scaled/thumb/593/4kem.png (stackoverflow won't let me post pics yet)

QPushButton {
   qproperty-icon: theme_url("/button_action/add");
   qproperty-iconSize: 14px; 
}

Is there a parameter I can use to adjust this space? I've tried margin, padding, spacing? Perhaps there is a different selector that I can use to just grab the icon?

Actually with QPushButton you are out of luck. You can find a complete list of working options for styling push buttons in the qt documentation ( I am assuming you use qt5, but it is available for other versions as well).

What is often recommended if you want more control over the icon is to exchange your QPushButtons with QToolButtons wich are exactly the same except that they have extra features to make them compatible with toolbars -and- they have more options for icon placement. But this might not work for you because as you can see they are styled the exact same way as QPushButtons. But do look into the "toolButtonStyle" parameter which allows you to move the icon around.

Next on the list comes changing the artwork. If all you want is more space then just add the extra empty pixels to the artwork. This really hurts the perfectionist's mind but is effective.

Next on the list comes subclassing QPushButton and overriding the paint yourself. Sounds more daunting than it is. Subclassing in Qt has become a habit already and it works great. Here is a tutorial i googled in a jiffie (for 4.8 but should be about the same for 5) on the matter of subclassing. It even covers overriding the paint event.

Hope this was helpful.
