Subject: Font hell tk4.2=>8.x Solution - DN [1]

 I have this widget which needs a font. In tk4.2 its control structure
 has a field of the form
     XFontStruct *fontPtr;
 which is used exactly once as part of Tk_GetGC in the XGCValues-type
  gcValues parameter via
     gcValues.font = this->fontPtr->fid.

 This fontPtr field is being filled in by Tk_ConfigureWidget by a Tk_Font
 object which also has an fid field (but not in the same location). It
 seems like the simple fix of changing the control structure to
     Tk_Font *fontPtr
 would work, but it does not compile. Or at least it does not compile
 if it only includes tk.h. But after changing the assignment above to
     gcValues.font = Tk_FontId(this->fontPtr);
 life was good again.

 I was kind of surprized both that this wasn't a FAQ and that I did not
 get any pointers from my original post.
