Qt How to change gridlayout column size

Question

Suppose I have a gridlayout of three columns. I want each column to have custom width. Seems to me that the width of the columns are fixed automatically.

How can I do this in the qt designer?

Answer 1

You can do it in the QT Designer (GUI)

1. First, use the Grid Layout widget (say, you want 3 column)
2. Second, in the Property Editor, choose the layoutColumnStretch and enter value (such as 200,100,100)

Result: 1st column 200px, 2nd column 100px, 3rd column 100px,
