QTabBar css styling

[jcbaar]

Hello all,

I have a couple of issues with styling the WinCC OA tab-control. We have a dark and light color theme which has, as the names suggest, light and dark colors defined.

issue #1:
When we load panels using a background color into the tab registers the tab pane uses the background color of the loaded panel as it should (execpt for the padding area unless explicitly set in the stylesheet on QTabWidget::pane). However when we then switch to the other theme only the background color of the loaded panel is properly set. The tab pane itself remains in the color if gets when the panel was first loaded into the register. This is especially noticeable when the panel loaded is smaller than the tab widget pane itself.

issue #2:
When we use anything in the stylesheet using QTabWidget::pane {} we get a thin line above the tab-bar tabs. For whatever reason this cannot be styled away...

Has anybody been able to work around these issues?

P.S. Forgot to mention. WinCC OA 3.18 Patch 13. I did not test on other versions...
