Adding GraphWin Member Functions

Not every operation of the programming interface of GraphWin is available in the interactive interface. However, there is an easy way of adding operations of type void GraphWin::func();. The operation 
    gw.add_member(void (*GraphWin::func)(), 
                  string label, int menu_id=0);

adds a new button with label label to the menu with id menu_id.

Example:

The following program adds a "redraw" button, that calls gw.redraw(), to the main menu bar, we use 
#include <LEDA/graphics/graphwin.h>

int main()
{
  leda::GraphWin gw;

  gw.add_member_call(&leda::GraphWin::redraw,"redraw");

  gw.display(); gw.edit();
 
  return 0;
}
