I'm building out my first GUI which goes deeper than a yes no button. I've been struggling with this problem longer than its worth, since its probably simple.
I have the following layout in designer:
While I have the vertical spacing as desired, I want the QOpenGLWidget to take up most of the horizontal space. I cannot get the left layout to stop expanding when I expand the size of the window. I would assume I could set the layout to a fixed width, but that does not seem possible.
