11 Drag'n'drop is a way to transfer information between multiple applications.
|
|
|
12 To do this serveral GUIs define their own protocols. Examples are OffiX, CDE,
|
|
|
13 Motif, KDE, MSWindows, GNOME, and many more. To catch all these protocols,
|
|
|
14 XEmacs provides a generic API.

38 The OffiX Drag'n'Drop protocol is part of a X API/Widget library created by
|
|
|
39 Cesar Crusius. It is based on X-Atoms and ClientMessage events, and works with
|
|
|
40 any X platform supporting them.
|
|
|
41
|
|
|
42 OffiX is supported if 'offix is member of the variable dragdrop-protocols, or
|
|
|
43 the feature 'offix is defined.
|
|
|
44
|
|
|
45 XEmacs supports both MIME and URL drags and drops using this API. No application
|
|
|
46 interaction is possible while dragging is in progress.
