OnMarkClick

Unit: SDL_marksel
Class: TMarkSel
Declaration: property OnMarkClick: TMarkClickEvent;
{ TMarkClickEvent = procedure (Sender: TObject; X, Y: integer; Mark: integer) of object; }

The OnMarkClick event occurs when the user clicks the symbol array. The parameter Sender returns the address of the TMarkSel object which has been clicked. The parameters X and Y contain the mouse coordinates (in pixels relative to the upper left corner of the control) and the parameter Mark returns the number of the selected symbol. A zero value indicates that the "no symbol" field has been clicked.
