[Qt-creator] Adjusting styles of QtCreator

[Michael Jackson]

Yes, that does help. It gives me some starting points to experiment.

    From QFusionStyle drawing of e.g.  QStyle::SC_ScrollBarAddLine I’d think that that uses QPalette::Button as the base color.
    
    Qt Creator’s themes (can?) set that, e.g. share/qtcreator/themes/dark.creatortheme sets
    
    PaletteButton=shadowBackground
    
    (where “shadowBackground” is set to “ff232323” near the top of the file).
    
    There are also the flags  DerivePaletteFromTheme and  ApplyThemePaletteGlobally which influence if and how the palette in the theme is actually applied, not sure what does what exactly.
    The default theme, flat.creatortheme doesn’t seem to set the application palette, which probably means that it uses whatever Qt sets as the palette for Qt applications. (Which is why it might make a difference against which Qt you compile Qt Creator in that case, I suppose).
    
    I hope that gives you some useful pointers :)

Or the name of the subclass that scroll handles/widgets are? I just have a hard time believing that I have to completely change linux distributions or window managers just to get a different color scroll handles. We change the colors on our own application and those changes are reflected  in the application. QtCreator does it because when you change themes, you get different scroll handle colors. I just trying to track down which setting in the theme file actually effects those colors. Thank you to anyone that could help my old eyes out.

Clearly the scroll handles are being styled through the .theme file because changing themes will restyle the scroll handles/background. I was hoping for an easier answer such as “.. adjust the following key:value in the theme file”. I guess I have to load up an entirely new desktop environment. Seems a bit over-kill but since Linux is not my full time desktop I guess this is the norm?
