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 direct way to that, say:

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

Answer 1

resize() might be better to use.

Example usage:

widget->resize(165, widget->height());

If content is larger than the widget, widget won't resize. In that case put all content on top of a QScrollarea. Then It'll resize and you can see the scrolling bars. – Wisner

Answer 2

widget->resize(165, widget->height());

Selector

Answer 3

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(...).

Answer 4

If the width won't change afterwards, you can use setFixedWidth:

widget->setFixedWidth(165);

Similarly, to change the height without changing the width, there is setFixedHeight.

Never use fixed width! For varius reselutions it will not work. – Damiondamita

And you can't change your size in the future. Bad answer. – Expeditious
