| 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. | |

| 25 The current release of XEmacs only support a small set of Drag'n'drop | |
| 26 protocols. Some of these only support limited options avaiable in the API. | |

| 29 * OffiX DND:: A generic X based protocol. | |
| 30 * CDE dt:: Common Desktop Environment used on suns. | |

| 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. | |
