Remarks

The TOGGLEBUTTON widget is used to input or display binary data. Clicking the mouse button (or pressing the Spacebar or the Return key) while the focus is on the TOGGLEBUTTON causes a CHANGED event to be generated.

The TOGGLEBUTTON widget is similar to the PUSHBUTTON widget in that when you click on the widget, an event is generated. The TOGGLEBUTTON is useful for emulating a two-position switch, or for setting a mode of operation.

For the TOGGLEBUTTON widget, the event is called CHANGED and theTOGGLEBUTTON VALUE attribute is toggled between 0 and 1 every time you click on the widget. A small box changes highlighting to reflect the value. The default is 0.

Events

Events for the TOGGLEBUTTON widget are:

CHANGED

This event is generated when the user "presses" the TOGGLEBUTTON either by clicking on it with the left mouse button or by pressing the Spacebar or the Return key.
