restorGeometry() is not working... or maybe a contained Widget/layout causes resize?

[davethomaspilot]

I'm using saveGeometry/saveState and restorGeometry/restoreState as documented here:

http://doc.qt.io/qt-4.8/restoring-geometry.html

When I start the application, the QMainWindow has the same width as when it was closed, but its height grows so that the bottom part of the widget is not visible. I resize the window and exit, but the new height is not restored on the next application start-up.

If I set a maximum size on the QMainWindow, this can be avoided. But, I don't want to do that since at a different screen resolution, a bigger QMainWindow height wouldn't be an issue.

Can a layout or widgets inside a QMainWindow cause it to grow in size after its geometry is restored?

If not, what else might be causing this?

Depends on when you restore the geometry.

When it is done before the layouts have done their work, then the window might grow if the current size is smaller than the overall preferred size.
