I'm probably overlooking something simple, but what events are best for updating a TLabel with an TImageMView's MultiSelectedImagesCount?

I need to do it when the user clicks on a thumbnail or navigates with the keyboard.

I'm trying OnImageSelect, but I'm not getting the correct number.

Thanks!

Hello,

Try to put your code in OnMouseUp event.

Also, we have added TImageEnMView.OnSelectionChanged in the upcoming version.

Thanks!

After poking around some more, I had a EUREKA! moment and discovered

OnAfterEvent

Not that I completely understand the entire TImageEnMView event cycle, but that seems to allow me to update my lblImageGridStatus without any noticeable overhead.

Just to share, here's the code I call:

procedure TfrmAssetCurator.ImgGridStatus;
var imgMV: TImageEnMView;
  s: String;
begin
  if (iNavGrid = 0) then
    imgMV := ImgMView
  else
    imgMV := ImgMViewTarget;

  s := IntToStr(imgMV.ImageCount) + ' files';

  if (imgMV.MultiSelectedImagesCount > 0) then
    s := s + ', ' + IntToStr(imgMV.MultiSelectedImagesCount) + ' selected';

  if (imgMV.CheckedCount > 0) then
    s := s + ', ' + IntToStr(imgMV.CheckedCount) + ' checked';

  Talk (lblImageGridStatus, s);
end;

Cheers,
Skip
