Qt designer - how to change splitter sizes ?

[TorAn]

I will appreciate the helping hand to show how to change the width of a splitter parts in Qt designer. I'd like to be able to drag the left or right size of the splitter to change design area.

Thanks.

up. (Am I the only one who is using splitters in Qt designer and does not know how to change the size of individual panels?)

The QSplitter are not live QWidgets in QtCreator unfortunately.
If your QSplitter contains two widgets, you can set maximumSize and sizePolicy for each widget and the QSplitter will resize accordingly. I didn't find a way to do the same things with its QLayout chidren.

Alternatively, you can break the layout that you made, resize the widgets by hand with a proportion that matches what you want to get ultimately (if want to have a splitter set in a ~1/4, 3/4 ratio, you can resize a widget to ~1cm and the other to ~3cm), and then re-create the layout/splitter and container layout. This will create the splitter and expand it in its container layout keeping the proportion that you defined.
