I've been trying to learn how to use the ListMgr recently. I started with
a bare bones Think C program (4.05) that just opens a dialog and initializes
a list. It works with the default LDEF (number 0), highlighting the cells
as I click on them. But with I wrote my own LDEF using Think C, and put
it into my resource file, I can't get anything to appear on the screen.
This is my LDEF :

pascal void main(lMessage,lSelect,lRect,lCell,lDataOffset,lDataLen,lHandle)
int lMessage;
Boolean lSelect;
Rect *lRect;
Cell lCell;
int lDataOffset;
int lDataLen;
ListHandle lHandle;
{
	GrafPtr	savePort;
	
	RememberA0();
	SetUpA4();
	
	switch (lMessage) {
		case lInitMsg :
			break;
		case lDrawMsg :
			EraseRect(&lRect);
			break;
		case lHiliteMsg :
			InvertRect(&lRect);
			break;
		case lCloseMsg :
			break;
		}; /* End Switch (lMessage) */
	
	RestoreA4();
}

I build the LDEF as stated in the Think C Manual. Now, after pouring over the
IM IV manual, I still have no idea whats going on. Also, once I build the
LDEF, I use ResEdit to copy it into my applications rsrc. Any help or
sample code would be appreciated.
