Seems like if the drag mode for the TImageEnMView is set to dmAutomatic, I cannot select a different thumbnail to drag since it seems to start the drag operation on mouse down instead of on mouse move as with other controls like TListView.

Am I missing a setting somewhere?

Hi Eric

Have you tried the DragDrop demos:

- Demos\Multi\DragDrop_MultiView\TImageEnMView_DragDrop.dpr
- Demos\Multi\Multiview2\Multiview2.dpr

Yes, but those have the drag mode set to manual, requiring having to add code to the mouse move event. Usually one does not need to do that and instead simply set the drag mode to automatic as in the case with TListView.

Eric

P.S. 2nd example mentioned does not even have drag that I see.

Hi Eric

Unfortunately because of some special handling needed by MView, dmAutomatic is not supported.

The correct list of demos should be:

\Demos\Multi\DragDrop_MultiView2\Multiview2.dpr
\Demos\Multi\DragDrop_MultiView\TImageEnMView_DD.dpr
\Demos\LayerEditing\DragDropLayers\Layers_DragDrop.dpr
\Demos\Multi\DragDrop_FileList_2\TImageEnMView_FileList.dpr

Thanks, no big deal as the amount of code is trivial. Just didn't know if it was a bug or something I was doing wrong.
