I'm working on trying to support some theme/skin changes to my toolbars in a legacy app. I'm having some difficulty isolating one of the settings.
For reference I'm using the "Win8 metro" theme on Windows 10. When I view it in skinstudio I find that the image that successfully changes my toolbar background color is: "toolbar_back.bmp".
I want to be able to load a full theme, but switch out this particular value manually elsewhere. I thought this setting use to be controlled in the registry, but all of the windowblind themes are using an single color image to overlay this toolbar. Is that the only way this toolbar background color is modifiable? Overlaying an image? Or can this be done with an rgb value?
