**Member function pointer -** 2005.10.31, 12:10 AM

Excuse my bad memory, but I forgot the syntax.

I have a class that has this definition in it...

Code:

class WorldObject
{
...
void (WorldObject::*draw)();
void drawCube();
};

When I initialize an instance of a WorldObject, I assign drawCube to draw.

Code:

draw = &WorldObject:drawCube;

When I want to draw, I call:

Code:

WorldObject * wo = &(worldObjects[i]);
((WorldObject*)wo->*draw)();

I get a syntax error, saying that it is of unknown type when I try and call the draw function. What gives?
