How to resize pushbutton to fit text in mac os

[tintu]

I am trying to make a QPushbutton that will increase in size to fit the text platform independently.
The text can be very long and I need the button to size itself so that all the text can be visible.

For example: I have a button with text "Restore defaults" , it is visible in win 7 . When i run this in mac os , only a part of the text ("tore defaults") is displayed.
Could anyone tell me how to solve this problem, to make all the text appear on the button.

When you build widget with use of layout this should be done automatically out of the box.
You may have to use size policy - set it for main window / central widget.
