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 :) Br, Eike > On Jan 22, 2019, at 16:16, Michael Jackson <mike.jack...@bluequartz.net> > wrote: > > It has been a long time since I rummaged through the QtCreator code, code I > get an assist and point be to where the Styles/Themes are either loaded or > applied?
