|

387 TYPE is a symbol, either `empty', `key-press', `button-press',
|
|
288
|
388 `button-release', `misc-user' or `motion'. If TYPE is nil, it
|

390
|
|
|
391 PLIST is a property list, the properties being compatible to those
|
|
|
392 returned by `event-properties'. The following properties are
|
|
|
393 allowed:
|
|
|
394
|
|
|
395 channel -- The event channel, a frame or a console. For
|
|
288
|
396 button-press, button-release, misc-user and motion events,
|
|
|
397 this must be a frame. For key-press events, it must be
|
|
|
398 a console. If channel is unspecified, it will be set to
|
|
|
399 the selected frame or selected console, as appropriate.
|
|
213
|
400 key -- The event key, a symbol or character. Allowed only for
|
|
|
401 keypress events.
|
|
215
|
402 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
282
|
403 button-press, button-release and misc-user events.
|
|
213
|
404 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
215
|
405 for key-press, button-press, button-release, motion and
|
|
282
|
406 misc-user events.
|
|
288
|
407 function -- Function. Allowed for misc-user events only.
|
|
|
408 object -- An object, function's parameter. Allowed for misc-user
|
|
|
409 events only.
|
|
213
|
410 x -- The event X coordinate, an integer. This is relative
|
|
|
411 to the left of CHANNEL's root window. Allowed for
|
|
282
|
412 motion, button-press, button-release and misc-user events.
|
|
213
|
413 y -- The event Y coordinate, an integer. This is relative
|
|
|
414 to the top of CHANNEL's root window. Allowed for
|
|
282
|
415 motion, button-press, button-release and misc-user events.
|
|
213
|
416 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
215
|
417 all types of events. If unspecified, it will be set to 0
|
|
|
418 by default.
|
|
213
|
419
|
|
|
420 For event type `empty', PLIST must be nil.
|
|
189
|
421 `button-release', or `motion'. If TYPE is left out, it defaults to
|
|
|
422 `empty'.
|
|
|
423 PLIST is a list of properties, as returned by `event-properties'. Not
|
|
|
424 all properties are allowed for all kinds of events, and some are
|
|
|
425 required.
