-
- ; This is the code to create simple text widgets. Text widgets
- ; come in two varieties: editable and non-editable. The VALUE of
- ; a text widget is equal to the text string displayed in the
- ; text widget.
-
- ; For an example of text widgets in 'action' see
- ; the procedure WORLDROT.PRO available from the 'Simple Widget
- ; Examples' widget by selecting 'World Rotation Tool'.
-
-
- PRO wtext_event, event
-
- ; This event handler for the example text widgets
- ; does not really do anything. It's just here to remind
- ; you that you generally need an event handler when
- ; you are programming widgets.
-
- ; For this example, we aren't doing anything with either
- ; of the text widgets.
-
- ; Text widgets can, however, have
- ; USER VALUES so you could use a CASE statement to execute some IDL
- ; commands if a text widget were manipulated. You could also use the
- ; GET_VALUE keyword to the WIDGET_CONTROL routine to return
- ; the text string currently present in a text widget.
