TCustomForm.OnShow property

Declaration

property OnShow: TNotifyEvent read FOnShow write FOnShow;

Description

OnShow is a TNotifyEvent property with the event handler signalled (when assigned) when the form becomes visible. It is signalled from the DoShow method when the CM_SHOWINGCHANGED control messages is handled for the form, and when queued OnResize and OnChangeBounds events are executed for the form.

Create and assign a procedure to OnShow to perform any actions needed when the Visible property for the form is set to True.
