Is this WAD? It would be handy to use the OnZoomIn/Out events to update a display of zoom percentage whenever it changes, however when zoom is changed programmatically, the events are not called.

eg

myIEview.Zoom := 30; //no event triggered

zoom with mouse - events are triggered

Hi

Yes, this is as per the documentation:

Also see the reason at:

There are methods that end up calling the events when called programmatically, eg TImageEnView.ZoomIn/ZoomOut. The calls to the events should then be removed to be consistent with the documentation.

Hi

Yes, you are correct (as ZoomIn/Out were initially intended only as internal methods). I have clarified this in the documentation.
