Events


Unit:SDL_numio
Class:TNumIO
Declaration: property OnChange: TNotifyEvent;
property OnClick: TNotifyEvent;
property OnDblClick: TNotifyEvent;
property OnEnter;
property OnExit;
property OnKeyDown: TKeyEvent;
property OnKeyPress: TKeyPressEvent;
property OnKeyUp: TKeyEvent;
property OnMouseMove: TMouseMoveEvent;
property OnMouseDown: TMouseEvent;
property OnMouseUp: TMouseEvent;

The OnChange event is triggered whenever the text of the TNumIO control changes (even if it is changed by the program and not by the user). All other events perform like the corresponding standard events of other Delphi/C++Builder controls (see the compiler manuals for more details).

Example: Some of these events are used in the following example programs (see http://www.lohninger.com/examples.html for downloading the code): gradfill, numin, poldiag, simplegeomap
