Area that can be stretched

Hello!

How can I make an area that can be stretched?

I would like to have a line between two parts of the window and resize them by dragging the line.

I have looked in the documentation and in Qt Designer but I find nothing that rings a bell.

Thank you!

Have a look at QSplitter. And in designer there are also tool buttons for laying out objects in a splitter.

Thank you!

This is what I was looking for.
