Hi,

Short version: For a higher contrast, you can set  "PreferredStyles=Windows" in 
the "[General]" section of your *.creatortheme file.

Long version:
You can influence palette colors in the *.creatortheme files like this:
...
  [Colors]
  PaletteButton=ffff0000
...
"PaletteButton" sets the QPalette::Button ColorRole for the whole application. 
All other ColorRoles are mapped accordingly. Depending on the used QStyle, 
despite its name PaletteButton also influences the scroll bar color (at least 
this is the case with FusionStyle).

Which QStyle is used depends on the theme and OS. The theme may force the style 
via:
...
  [General]
  PreferredStyles=Fusion
...

If you use HighDpi, FusionStyle is forced unless you are on macOS.

Br,
Alessandro

Betreff: Re: [Qt-creator] Adjusting colors in one of the Themes

Thanks but those are for the little highlight marks that appear in the
scroll bar. I want to change the color of either the scrollbar handle
itself or the scrollbar background. Those two are so close in contrast
that they are very hard to tell apart. It wonder if the scrollbar colors
are baked into the actual source code for QtCreator? Or maybe one of the
"Styles" that Qt supports on Windows?

Could a QtCreator developer maybe point to the place in the source code
where the styles and colors are initialized?
