TCustomBitmap.Changed procedure
Performs actions needed when the image data for the bitmap has been changed.
Declaration
procedure Changed(Sender: TObject); overrideDescription
Changed is an overridden method in
TCustomBitmap.
Changed examines the value in
Sender to determine the origin for
the change.
When Sender is the Canvas for the class instance, the image was
changed after an update to its Canvas. The raw image data in the
shared image is no longer valid, and it is freed. The inherited method is
called to free the save stream for the shared image, set the value in
Modified, and signal the OnChange event handler (when
assigned).
