Hi! Any chance for a small change to ComboBoxBase? The button in there is created as final in the constructor (line 50), so I can't currently replace it with my own Button subclass (which uses some GLSL magic for game-specific rendering).

Could you please move the creation of that button instance to an overloadable method like the createColumnHeader method in TableBase? All other buttons (that I encountered so far) could easily be replaced, except for this one.

Not easily - as the button is constructed in the constructor you can't easily call an virtual method as the constructor of the subclass has not yet run. Eg any fields of your subclass would be uninitialized at this point.

But if you only want to adjust the rendering you could just install a custom background/overlay Image which does the GLSL based rendering you want (make sure to set the button theme to "" so that your image is not replaced by one from the theme).
