I am attempting to call an event handling procedure for a
draw_motion_event that is called 'read_pixel'. I need to inculde a
parameter, 'pointer' in my call, but idl does not recognize
'read_pixel, pointer' as an acceptable call:
IDL:> Attempt to call undefined procedure/function: 'READ_PIXEL,
POINTER'.
Here is my line that calls the procedure:
IDL:>widget_control, data, event_pro = 'read_pixel, pointer'$
, Draw_motion_events = 1
