How to fix size of a widget?

Hello,

I'm trying to implement a window with frames including labels.

But they are not correctly aligned.

There is set_size_allocate() . Is it a good setting to use? and how to use it?.

If I understand, I can use it only if the widget is realized and I have to create a Gdk::Rectangle.

If i set_text() in the label when the program is running, it redraws.

So how to choose the size of a widget and force it to not redraw ?

Thanks.
