Procedural type that is used for all OnMouseUp and OnMouseDown event types.

A TMouseEvent event handler must be called with the following parameters:

  • Sender--a pointer to the object that called this function.
  • Button-- indicates which mouse button is pressed
  • Shift--indicates which shift keys--SHIFT, CTRL, ALT, and CMD (only for Mac)--were down when the user pressed the mouse button.
  • X and Y--the pixel coordinates of the mouse pointer within the client area of the control.
