how to, get pushbutton text on 2 lines, instead of just 1?GUI

[Nikolaj]

i have a pushbutton in my gui which hass a label on it which is to large to fit on a single line. I dont have the option to make the dimension of the button bigger so the only solution is to either make the text smaller, or to somehow make the text be on 2 lines inside the button.
I've been spending a few hourss trying to make the text to be on 2 lines but no succes. can anyone help?
