The 'onClick' callback

Event number: 24
Generated for: All visible controls

The onClick callback is run after the user has pressed the mouse button in the object (a MouseDown event will be created first). It indicates that the object has been selected (or de-selected, in the case of a Radio button). It is also triggered for a List if the user changes the selected item using the keyboard, and for an Edit, RichEdit or Document object if the selection/insertion point changes as a result of user input.
