; Activate Button Callback Procedure.
; Argument:
;   Event structure:
;
;   {WIDGET_BUTTON, ID:0L, TOP:0L, HANDLER:0L, SELECT:0}
;
;   ID is the widget ID of the component generating the event. TOP is
;       the widget ID of the top level widget containing ID. HANDLER
;       contains the widget ID of the widget associated with the
;       handler routine.

;   SELECT is set to 1 if the button was set, and 0 if released.
;       Normal buttons do not generate events when released, so
;       SELECT will always be 1. However, toggle buttons (created by
;       parenting a button to an exclusive or non-exclusive base)
;       return separate events for the set and release actions.

;   Retrieve the IDs of other widgets in the widget hierarchy using
;       id=widget_info(Event.top, FIND_BY_UNAME=name)

; Slider Value Changed Callback Procedure.
; Argument:
;   Event structure:
;
;   {WIDGET_SLIDER, ID:0L, TOP:0L, HANDLER:0L, VALUE:0L, DRAG:0}
;
;   ID is the widget ID of the component generating the event. TOP is
;       the widget ID of the top level widget containing ID. HANDLER
;       contains the widget ID of the widget associated with the
;       handler routine.

;   VALUE returns the new value of the slider. DRAG returns integer 1
;       if the slider event was generated as part of a drag
;       operation, or zero if the event was generated when the user
;       had finished positioning the slider.

;   Retrieve the IDs of other widgets in the widget hierarchy using
;       id=widget_info(Event.top, FIND_BY_UNAME=name)
