Event handler signalled when the size or layout for child controls has been changed.
Declaration
property OnChange: TNotifyEvent read FOnChange write FOnChange;Description
OnChange is a
TNotifyEvent property with the event
handler signalled (when assigned) from the Change method. It occurs after
child controls have been resized and/or realigned.
The Sender argument is the TControlChildSizing instance for the
event notification.
In a TWinControl instance, its DoChildSizingChange method is assigned as the default handler routine used in OnChange. It invalidates the preferred sizes for the child controls, and calls their Realign method.
