OnLastImageRequest

Unit:SDL_thumbnails
Class: TThumbnails
Declaration: property OnLastImageRequest: TNotifyEvent;

The OnLastImageRequest event occurs after the thumbnail update cycle has finished. Thus when painting the thumbnails on the canvas the sequence of events is as follows:
1 x OnFirstImageRequest,
p x OnImageRequest, and
1 x OnLastImageRequest,
with p being less than or equal to NumSlidesHoriz * NumSlidesVert.

The OnLastImageRequest event can be used to reset for example the screen cursor (which has been previously set in the OnFirstImageRequest event).

Example: This event is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): jpg_browser
