CTreeCtrl with Symbol font.
-
I need to display labels in a CTreeCtrl using a symbol font. It seems that if I set any symbol font in the CTreeCtrl it stops drawing completely, apart from its border. No lines, no plus/minus gadgets, no icons, no labels. Nothing. :-( Am I doing something stupid? Is there a way to fix this without writing my own tree control? Will I solve this before I go postal? (I've tried doing the same thing with a CEditCtrl and it worked fine.) Any help would be much appreciated. --Leo

Hmm... I tried populating the list BEFORE I changed the font and it worked. Further investigation revealed that the InsertItem calls were failing if the font had been set. Although InsertItem is not documented as indicating the error reason (sigh!), GetLastError consistently returned 1004 (invalid flag). The only flag I could find relating to fonts was TVIS_BOLD, but setting this has no effect. I am a bit worried that I don't understand why it works one way and not the other. Ideas appreciated! For now, I'll hope it continues to work so long as I populate before setting the font.
