Event handler for check-boxes
virtual void OnCheckBox( UINT id, BOOL bChecked, const CXlControlCheckBox* ctl );
ID of the button which was pressed.
New checked state of the button which was pressed.
Pointer to the control which originated the event.
This overrideable function is called whenever a check-box (CXlControlCheckBox) is checked or unchecked. Note that it will only be called if the check box has been set to trigger events (see CXlControl::SetTrigger()).
Its default behaviour is to do nothing.
