When using

ImageEnMView1.AttachedImageEnView := ImageEnView1

Should the file be loaded using ImageEnMView1 or ImageEnView1

When loading using ImageEnMView1, the navigation doesn't work on page 1. You CANNOT MouseWheel back to page 1 once you've left it.

Hi Jeff

I'm not seeing that. Try adding this code:

  // Mouse wheel scrolls through the images (with secondary actions if Ctrl is pressed)
  ImageEnView1.MouseWheelParams.Action := iemwNavigate;
  ImageEnView1.MouseWheelParamsAlt.Action := iemwZoom;
  IEFolderMView.MouseWheelParams.Action := iemwNavigate;
  IEFolderMView.MouseWheelParamsAlt.Action := iemwVScroll;


To the demo:
\Demos\Multi\MView_AttachedViewer\MViewPreview.dpr

Hi

You should be loading it using ImageEnMView1.MIO.LoadFromFile();

(Except in the special case of PDF files).

I'm still having an issue mouse wheeling back to the first page.


FViewer := TImageEnView.Create(AOwner);
FThumbs := TImageEnMView.Create(nil);
FThumbs.AttachedImageEnView := FViewer;

FViewer.MouseWheelParams.Action := iemwNavigate;
FViewer.MouseWheelParamsAlt.Action := iemwZoom;
FThumbs.MouseWheelParams.Action := iemwNavigate;
FThumbs.MouseWheelParamsAlt.Action := iemwVScroll;


I loads with page 1 displaying in the Viewer, but then when I mouse wheel down to page 2 and then back to page 1 the Viewer still displays page 2, but the Thumbs pane does select page 1.

So page 1 gets selected in the thumbs pane, but the does NOT get loaded in the Viewer.

By the way, I'm loading a multi-page TIF file. It works fine when I load a PDF.
