TApplication.OnDeactivate property
Event handler signalled when a Deactivate message is handled in the application.
Declaration
property OnDeactivate: TNotifyEvent read FOnDeactivate write FOnDeactivate;Description
OnDeactivate is a
TNotifyEvent property with the event
handler signalled when a
Deactivate message is handled in the
application.
It is signalled from the NotifyDeactivateHandler method, and
occurs when the Deactivate method is called for the application. The event
handler is also signalled (via Deactivate) from the WMActivate
method in TCustomForm to ensure that the application is
de-activated when its main form is de-activated.
Use the OnActivate event handler to perform actions needed when
the application is activated.
Use the TApplicationProperties class to assign properties and
event handlers at design-time that are applied to the application instance at
run-time.
