386 TYPE is a symbol, either `empty', `key-press', `button-press',

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

391 returned by `event-properties'. The following properties are
|
|
|
392 allowed:
|
|
|
393
|
|
|
394 channel -- The event channel, a frame or a console. For
|
|
288
|
395 button-press, button-release, misc-user and motion events,
|
|
|
396 this must be a frame. For key-press events, it must be
|
|
|
397 a console. If channel is unspecified, it will be set to
|
|
|
398 the selected frame or selected console, as appropriate.
|
|
213
|
399 key -- The event key, a symbol or character. Allowed only for
|
|
|
400 keypress events.
|
|
215
|
401 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
282
|
402 button-press, button-release and misc-user events.
|
|
213
|
403 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
215
|
404 for key-press, button-press, button-release, motion and
|
|
282
|
405 misc-user events.
|
|
288
|
406 function -- Function. Allowed for misc-user events only.
|
|
|
407 object -- An object, function's parameter. Allowed for misc-user
|
|
|
408 events only.
|
|
213
|
409 x -- The event X coordinate, an integer. This is relative
|
|
|
410 to the left of CHANNEL's root window. Allowed for
|
|
282
|
411 motion, button-press, button-release and misc-user events.
|
|
213
|
412 y -- The event Y coordinate, an integer. This is relative
|
|
|
413 to the top of CHANNEL's root window. Allowed for
|
|
282
|
414 motion, button-press, button-release and misc-user events.
|
|
213
|
415 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
215
|
416 all types of events. If unspecified, it will be set to 0
|
|
|
417 by default.
|
|
213
|
418
|
|
|
419 For event type `empty', PLIST must be nil.
|
|
189

420 `button-release', or `motion'. If TYPE is left out, it defaults to
|
|

421 `empty'.

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

423 all properties are allowed for all kinds of events, and some are

424 required.
