The TTouchEvent type is a common event type that is used by controls to provide notification that a touch event is occurring via a touch interface.

The Sender parameter represents the class instance that triggered the event. The ShiftKey, CtrlKey, AltKey parameters represent whether the Shift, Control, and/or Alt keys were also pressed. The X and Y parameters indicate the horizontal and vertical position of the touch, in pixels, relative to the bounds of the control that triggered the event.
