I'm all for it.
Although I'm not sure that this can be implemented in a cross-platform way.
On Windows, the intra-app drag/drop is handled using OLE/DDE.
On Linux, there is no such thing, and I think it depends on the used
desktop software (KDE vs Gnome). I don't know how it is done in Mac.
But your suggestion is at least a step in the right direction.
I would implement support in 2 objects:
TFileDragObject (external files, as dropped by file managers)
TExternalDragObject (external app DnD)
Both are created whenever an external DnD is found.
Files dropping is already implemented, and I'm pretty sure that Qt supports
DnD across different apps on all platforms. Haven't studied gtk2 in this case,
but your suggestion looks good.
I know about the File DND, but as far as I know, it's only on form level,
it could be extended to any control (TFileNameEdit jumps to mind).
