Review request for Solid.


Description
-------

It really took me two hours to find this bug but now I have found it: Seems like a bug in Qt or in the Oxygen theme: When there is a QScrollArea inside a QTabBar, and this QScrollArea contains a generated widget applied by setWidget, this widget in the first tab of the tab list (and the default selected one) are not opaque, making the gradient invisible. (Sorry, could not describe better).

After I found out that that ScrollArea is not needed at all but the QTabBar provides scrollbars by itself, I removed all that stuff, and just added a QGridLayout (first thing I could think of that could hold widgets) to hold our EditWidget. Now all the backgrounds are correct. And as far as I can tell this also had the little side-effect that now the config dialog of the battery plasmoid is sized properly initially. (Did not verify if this is really related to this patch though)


This addresses bug 307648.

Testing
-------

Opened the dialog, the "ON AC Power" tab has proper background. When resizing the dialog, scroll bars appear. It also works when the tabbar is hidden (when no batteries present - just saw: the battery detection code could be simplified like in the other KCM (hasBattery rather than batteryCount)).


Thanks,
