|

398 TYPE is a symbol, either `empty', `key-press', `button-press',
|
|
213
|
399 `button-release', `motion' or `dnd-drop'. If TYPE is nil, it
|
|
|
400 defaults to `empty'.
|
|
|
401
|
|
|
402 PLIST is a property list, the properties being compatible to those
|
|
|
403 returned by `event-properties'. The following properties are
|
|
|
404 allowed:
|
|
|
405
|
|
|
406 channel -- The event channel, a frame or a console. For
|
|
215
|
407 button-press, button-release, motion and dnd-drop
|
|
|
408 events, this must be a frame. For key-press
|
|
|
409 events, it must be a console. If channel is
|
|
|
410 unspecified, it will be set to the selected frame
|
|
|
411 or selected console, as appropriate.
|
|
213
|
412 key -- The event key, a symbol or character. Allowed only for
|
|
|
413 keypress events.
|
|
215
|
414 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
415 button-press, button-release and dnd-drag events.
|
|
213
|
416 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
215
|
417 for key-press, button-press, button-release, motion and
|
|
|
418 dnd-drop events.
|
|
213
|
419 x -- The event X coordinate, an integer. This is relative
|
|
|
420 to the left of CHANNEL's root window. Allowed for
|
|
215
|
421 motion, button-press, button-release and dnd-drop events.
|
|
213
|
422 y -- The event Y coordinate, an integer. This is relative
|
|
|
423 to the top of CHANNEL's root window. Allowed for
|
|
215
|
424 motion, button-press, button-release and dnd-drop events.
|
|
213
|
425 dnd-data -- The event DND data, a list of (INTEGER DATA). Allowed
|
|
|
426 for dnd-drop events, if support for DND has been
|
|
|
427 compiled into XEmacs.
|
|
|
428 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
215
|
429 all types of events. If unspecified, it will be set to 0
|
|
|
430 by default.
|
|
213
|
431
|
|
|
432 For event type `empty', PLIST must be nil.
|
|
189
|
433 `button-release', or `motion'. If TYPE is left out, it defaults to
|
|
|
434 `empty'.
|
|
|
435 PLIST is a list of properties, as returned by `event-properties'. Not
|
|
|
436 all properties are allowed for all kinds of events, and some are
|
|
|
437 required.
