Examples of org.eclipse.swt.widgets.ToolItem.addSelectionListener()

org.eclipse.swt.widgets.ToolItem.addSelectionListener()
Adds the listener to the collection of listeners who will be notified when the control is selected by the user, by sending it one of the messages defined in the SelectionListener interface.
When widgetSelected is called when the mouse is over the arrow portion of a drop-down tool, the event object detail field contains the value SWT.ARROW. widgetDefaultSelected is not called.

When the SWT.RADIO style bit is set, the widgetSelected method is also called when the receiver loses selection because another item in the same radio group was selected by the user. During widgetSelected the application can use getSelection() to determine the current selected state of the receiver.
@param listener the listener which should be notified when the control is selected by the user, @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT - if the listener is null
@exception SWTException
- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
