|
|
|
401 allowed:
|
|
|
402
|
|
|
403 channel -- The event channel, a frame or a console. For
|
|
215
|
404 button-press, button-release, motion and dnd-drop
|
|
|
405 events, this must be a frame. For key-press
|
|
|
406 events, it must be a console. If channel is
|
|
|
407 unspecified, it will be set to the selected frame
|
|
|
408 or selected console, as appropriate.
|
|
213
|
409 key -- The event key, a symbol or character. Allowed only for
|
|
|
410 keypress events.
|
|
215
|
411 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
412 button-press, button-release and dnd-drag events.
|
|
213
|
413 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
215
|
414 for key-press, button-press, button-release, motion and
|
|
|
415 dnd-drop events.
|
|
213
|
416 x -- The event X coordinate, an integer. This is relative
|
|
|
417 to the left of CHANNEL's root window. Allowed for
|
|
215
|
418 motion, button-press, button-release and dnd-drop events.
|
|
213
|
419 y -- The event Y coordinate, an integer. This is relative
|
|
|
420 to the top of CHANNEL's root window. Allowed for
|
|
215
|
421 motion, button-press, button-release and dnd-drop events.
|
|
213
|
422 dnd-data -- The event DND data, a list of (INTEGER DATA). Allowed
|
|
|
423 for dnd-drop events, if support for DND has been
|
|
|
424 compiled into XEmacs.
|
|
|
425 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
215
|
426 all types of events. If unspecified, it will be set to 0
|
|
|
427 by default.
|
|
213
|
428
|
|
|
429 For event type `empty', PLIST must be nil.
|
|
189
|
430 `button-release', or `motion'. If TYPE is left out, it defaults to
|
|
|
431 `empty'.
|

432 PLIST is a list of properties, as returned by `event-properties'. Not
|
|

433 all properties are allowed for all kinds of events, and some are
|
|

434 required.
