Qt- how to set QWidget width

Question

How to set QWidget width? I know setGeometry(QRect& rect) function to do that, but in that case I should use geometry() function to get former parameters of my QWidget, then I should increment the width and use setGeometry(..). Is there any ditect way to say

QWidget aa;
aa.setWidth(165); //something like this?

Answer 1

resize() might be better to use.

Answer 2

QWidget reference.

Try examining all available "yyysize" methods (because there are different sizing policies for Qt widgets and you might need something special).

Basically, yes, it's resize(...).
