Hi,

I am showing thumbnails from a connected device using TImageEnMView virtually using the ImageIDRequestEx event.

Is there anyway to know when the TImageEnMView viewport is full - i.e. drawing of the thumbnails is complete?

The number of thumbnails on these devices is often hundreds & I would like to show a progress/please wait message whilst the viewport is populated with the next page of thumbnails.

For this I would need to know when the viewport is "full" in order to remove the message form.

Thanks

Stuart Clennett

Hi Stuart

There is not an event for loading of all images in the control, because ImageEn will not check the status of images that are hidden until they are needed (when loading on demand).

Loading of all on-screen images triggers the OnAllDisplayed event when it completes.

Thanks Nigel, I didn't spot that event - just what's needed :)
