Question

I m using the "TEXTSTYLE" class with OpenThemeData in Vista/Win 7 to render text elements with the appropriate emphasis (all values found on the Parts and States documentation):

TEXT_MAININSTRUCTION for my header text
TEXT_SECONDARYTEXT for subtitles
TEXT_HYPERLINKTEXT for links
TEXT_INSTRUCTION for standard text

This looks great on a machine that supports the themes, but they re not available on XP. What would be an acceptable alternative for XP that still retains the basic "Header/Subheader/Body" visual distinctions?

Answer 1

Generally, your code still has provide fallback for cases, when user has disabled themes specially for your program, or globally on his Windows machine.

So the solution is to just provide the fallback, using the plain old GDI functions. You may derive the font by making it a bit larger or bold or something like that. On XP, this fallback will be used always for classes not available in Luna (the Microsoft-made styles distributed with XP).
