|Home GuiPack Thumbnails Events OnFirstImageRequest|
|See also: Events, OnLastImageRequest, OnImageRequest|
The OnFirstImageRequest event occurs when the thumbnail update cycle starts. Thus when painting the thumbnails on the canvas the sequence of events is as follows:
1 x OnFirstImageRequest,with p being less than or equal to NumSlidesHoriz * NumSlidesVert.
The OnFirstImageRequest event can be used to set for example the screen cursor to crHourGlass in oder to indicate that the loading of the thumbnails may take a while.
