Description

Hi,

another layout issue I encountered within the WVBoxLayout implementation. I have several rows using a WVBoxLayout. The last vbox row is resizeable. If I hide the containing widget in the last vbox row, the widget is hidden and the additional space is correctly setup to the vbox row with a stretch factor.

But if I change to height of the last vbox row by dragging the appropriate border. A following hide of the containing widget screws up the layout.

Attached you will find the test application which reproduces this problem. Hit apply to hide/show the widget of the last vbox row.

Hey Stefan,

I've made progress on fixing this issue: it works for your test case but I believe the problem isn't yet solved in its most general case (where resize handles become irrelevant when certain widgets are being hidden).

Nevertheless, I'm going to commit this already to git some time later today or tomorrow, since it certainly is no step backwards either.

Regards,

koen

Hi Koen,

Somewhat off topic, but could WHBoxLayout have the same issue? I saw some incorrect horizontal layout behavior that's similar to the problem described here. If it's related, you might kill two bugs with one stone, so to speak!

Thanks,

Peter

Hey Peter,

Yes, this is entirely symmetrical and the same code, so it could be solved too (although as I said, I didn't really solve it yet in its most general case).

I still haven't pushed my changes to the public git but will do so by the end of the week !

Regards,

koen
