increase size of button on StyleSheet?

[Kevin Hoang]

My buttons place in layout, how may increase size of them in stylesheet?

Like this:

QToolButton {
size-inc: 6px;
}

how about using
height : 20px;

I know height and width properties, but I want to calculate the current size and increase. My layout is fluid layout, so the button size is not fixed size.
