In the TImageEnFolderMView.OnDblClick event-handler, how can I detect whether the user has double-clicked on an image or white space? There is no parameter to indicate this. And clicking on white space does not deselect a selected image (like in File Explorer).

Get the mouse position using GetCursorPos(pt) and adjust it to the client position:

mc := ImageEnView1.ScreenToClient( Mouse.CursorPos );

Then check whether ImageEnMView1.ImageAtPos(mc.x, mc.y) returns -1.
