[paragui-users] Set/Get UserData from a widget

[Keith Swyer]

hey, just wondering if anyone has used the SetUserData or GetUserData
members of PG_Widget. I keep getting access violations when trying to get
the userdata, being a PG_Rect*.

This may not make much sense, but...

//temp is a PG_Button
temp->SetUserData((void*)temp->GetClipRect(), sizeof(PG_Rect*));

PG_Rect *temp;
if (itr->second->GetUserDataSize())
           itr->second->GetUserData((void*)temp);    //access violation here
