How to set display ratio between widgets in Qt layout?

Question

In a tab page I do have one tree view widget and one tab widget inside the vertical layout, I want to set 60% of screen space to tree view and 40% to tab widget, always. How can I do this in Qt Designer ?

Platform: Qt Creator 2.4.1 / Win 7.

If you click the parent widget and scroll down its properties, you will find the properties of its layout at the very bottom.

You can set the layoutRowStretch and layoutColumnStretch properties there. In case of a vertical layout, you could for example set "60,40" (or "6,4" or "3,2") as value for the layoutRowStretch property.

This will mean the factor of the first row to the second row will be 60:40 = 3:2
