[comp.windows.open-look] To what use is the DevGuide Text field event?

andrew@resam.dk (Leif Andrew Rump) (02/01/91)

My idear was to make a function that checked the date entered by the user
as the user typed it in, so I defined a text field (Data: _______) and an
event routine and this is what DevGuide gave me (my own indentation!):

/*
 * Event callback function for `date_txt'.
*/
void fk_date_event(item, event)
Panel_item      item;
Event           *event;
{
  panel_default_handle_event(item, event);
}

How do I for tell the notifier to ignore the last keystroke because the
user entered a letter when a number was expected? Normal XView programming
would allow me to _return_ PANEL_NONE to tell the notifier to discard the
input!!!
