Guys-
Thanks for the response. That's pretty much what I figured, I just wanted to be sure.
To clarify,
I will make:
static void StuffViewDrawName(...); // static method
Then, I will stuff into the TableRowData the 'this' pointer for the current object,
and then in my static callback, I can access things in the class like:
void
StuffViewDrawName(...)
{
StuffClass* myThis = grabTableData(row);
WinDrawChars(myThis->getTextString(), ...);
}
Does that sound like a plan?
BTW - thanks a TON for the quick help!
