TCustomCalendar.LMMonthChanged procedure
Handles the LCL LM_MONTHCHANGED message received when the month has been changed using the calendar control.
Declaration
procedure LMMonthChanged(var Message: TLMessage); messageArguments
Message | Message handled in the method. |
Description
The message is posted as a callback from the widgetset class when the active
month on the control is changed. It can occur when a new date is selected, or
when the GUI is used to change the visible month on the control.
LMMonthChanged ensures that event handlers are signalled (when
assigned) when the month displayed on the calendar control is changed. The
event handlers are signalled in the following order:
- OnMonthChanged
- OnChange
An application can assign object procedures to the event handlers to respond to the change notifications.
