Description

Hi,

I have an toolbar like WHBoxLayout which uses a hbox->addStretch(1) between two widgets to seperate between left rendered and right rendered widgets.

Attached you will see the layout of wt-3.2.3 which looks quite good and a wt-3.3.0 layout which looks not so good since the labels for some input control (Tree depth and %-Filter) are not directly rendered besides the appropriate input controls.

Regards,

Stefan

The addStretch(1) added between addWidget("Options") and the second right most icon.

Hi,

it seems to me that this is a Firefox v20/v21 problem. With Google Chrome and Opera it works as expected!

Hey Stefan,

I would like to dig into this issue. Some more questions to put me on the right track. The issue could be specific to the combobox in Firefox20/21? It even looks wrong if you do not add stretch?

regards,

Hi Koen,

removing the addStrech(1) does not fix the problem. See the attached screenshot.

Regards,

Stefan

Hey Stefan,

I'm trying to reproduce this issue. The attached test case works well, can you see if you can modify it so that it starts misbehaving?

Hi Koen,

I could reproduce the layout problem by modifiy our test case. I reduced the width of the spinbox to 50 pixel and then the layout is wrong. The problem seems to me that the layout engine within 3.3.0 uses the maximum width of the spinbox instead of the actual width. See the modified attached test case.
