408 PLIST is a property list, the properties being compatible to those

409 returned by `event-properties'. The following properties are
|
|
|
410 allowed:
|
|
|
411
|
|
|
412 channel -- The event channel, a frame or a console. For
|
|
215
|
413 button-press, button-release, motion and dnd-drop
|
|
|
414 events, this must be a frame. For key-press
|
|
|
415 events, it must be a console. If channel is
|
|
|
416 unspecified, it will be set to the selected frame
|
|
|
417 or selected console, as appropriate.
|
|
213
|
418 key -- The event key, a symbol or character. Allowed only for
|
|
|
419 keypress events.
|
|
215
|
420 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
421 button-press, button-release and dnd-drag events.
|
|
213
|
422 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
215
|
423 for key-press, button-press, button-release, motion and
|
|
|
424 dnd-drop events.
|
|
213
|
425 x -- The event X coordinate, an integer. This is relative
|
|
|
426 to the left of CHANNEL's root window. Allowed for
|
|
215
|
427 motion, button-press, button-release and dnd-drop events.
|
|
213
|
428 y -- The event Y coordinate, an integer. This is relative
|
|
|
429 to the top of CHANNEL's root window. Allowed for
|
|
215
|
430 motion, button-press, button-release and dnd-drop events.
|
|
213
|
431 dnd-data -- The event DND data, a list of (INTEGER DATA). Allowed
|
|
|
432 for dnd-drop events, if support for DND has been
|
|
|
433 compiled into XEmacs.
|
|
|
434 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
215
|
435 all types of events. If unspecified, it will be set to 0
|
|
|
436 by default.
|
|
213
|
437
|
|
|
438 For event type `empty', PLIST must be nil.
|
|
189
|
439 `button-release', or `motion'. If TYPE is left out, it defaults to
|
|

440 `empty'.
|

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