Hi,
How is it possible to generate an event when the user enters some characters
in a widget_text or when the focus change of widget_text?
With the small following example, I can catch only the Carriage Return key
pro test_event, event
print, event
end
pro test
w=widget_base( /COLUMN, /KBRD_FOCUS_EVENTS)
item1 = widget_text(w, value='1', /EDITABLE)
item2 = widget_text(w, value='2', /EDITABLE)
widget_control, /REALIZE, w
xmanager, 'test', w,/JUST_REG
end
