Description

Type of the event handler for the change or deletion of a gesture.

TGestureItemChangeEvent is the TGestureCollection OnItemChange event handler that fires when the gesture (also a parameter of this event handler) is deleted or changed.

Sender is the control that gestures apply to. This is the control that has the TGestureManager assigned to its TouchManager/GestureManager property.

Action is of type TGestureNotification and specifies whether the gesture was changed or deleted.

Item specifies the gesture from the collection that has been changed or deleted.
