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

346 allowed:
|
|
|
347
|
|
|
348 channel -- The event channel, a frame or a console. For
|
|
|
349 button-press, button-release, misc-user and motion events,
|
|
|
350 this must be a frame. For key-press events, it must be
|
|
|
351 a console. If channel is unspecified, it will be set to
|
|
|
352 the selected frame or selected console, as appropriate.
|
|
|
353 key -- The event key, a symbol or character. Allowed only for
|
|
|
354 keypress events.
|
|
|
355 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
356 button-press, button-release and misc-user events.
|
|
|
357 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
|
358 for key-press, button-press, button-release, motion and
|
|
|
359 misc-user events.
|
|
|
360 function -- Function. Allowed for misc-user events only.
|
|
|
361 object -- An object, function's parameter. Allowed for misc-user
|
|
|
362 events only.
|
|
|
363 x -- The event X coordinate, an integer. This is relative
|
|
|
364 to the left of CHANNEL's root window. Allowed for
|
|
|
365 motion, button-press, button-release and misc-user events.
|
|
|
366 y -- The event Y coordinate, an integer. This is relative
|
|
|
367 to the top of CHANNEL's root window. Allowed for
|
|
|
368 motion, button-press, button-release and misc-user events.
|
|
|
369 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
|
370 all types of events. If unspecified, it will be set to 0
|
|
|
371 by default.
|
|
|
372
|
|
|
373 For event type `empty', PLIST must be nil.
|
|
|
374 `button-release', or `motion'. If TYPE is left out, it defaults to
|
|
|
375 `empty'.
|
|
|
376 PLIST is a list of properties, as returned by `event-properties'. Not
|
|
|
377 all properties are allowed for all kinds of events, and some are
|
|
|
378 required.

1143 KEY-DESCRIPTION is the first argument, and the event to fill in is the

1144 second. This function contains knowledge about what various kinds of

1145 arguments ``mean'' -- for example, the number 9 is converted to the

1146 character ``Tab'', not the distinct character ``Control-I''.
|

1147
|

1157 If KEY-DESCRIPTION is an integer or character, the high bit may be

1160 be the case. If USE-CONSOLE-META-FLAG is non-nil, the `meta' flag for

1161 CONSOLE affects whether the high bit is interpreted as a meta

1162 key. (See `set-input-mode'.) If you don't want this silly meta

1166 Beware that character-to-event and event-to-character are not strictly

1168 Lisp character object type can encode.

1564
|
|
|
1565 `shift': The Shift key. Will not appear, in general, on key events
|
|
|
1566 where the keysym is an ASCII character, because using Shift
|
|
|
1567 on such a character converts it into another character rather
|
|
|
1568 than actually just adding a Shift modifier.
|
|
|
1569
|
|
|
1570 `control': The Control key.
|
|
|
1571
|
|
|
1572 `meta': The Meta key. On PC's and PC-style keyboards, this is generally
|
|
|
1573 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and
|
|
|
1574 such, propagated through the X Window System. On Sun keyboards,
|
|
|
1575 this key is labelled with a diamond.
|
|
|
1576
|
|
|
1577 `alt': The \"Alt\" key. Alt is in quotes because this does not refer
|
|
|
1578 to what it obviously should refer to, namely the Alt key on PC
|
|
|
1579 keyboards. Instead, it refers to the key labelled Alt on Sun
|
|
|
1580 keyboards, and to no key at all on PC keyboards.
|
|
|
1581
|
|
|
1582 `super': The Super key. Most keyboards don't have any such key, but
|
|
|
1583 under X Windows using `xmodmap' you can assign any key (such as
|
|
|
1584 an underused right-shift, right-control, or right-alt key) to
|
|
|
1585 this key modifier. No support currently exists under MS Windows
|
|
|
1586 for generating these modifiers.
|
|
|
1587
|
|
|
1588 `hyper': The Hyper key. Works just like the Super key.
|
|
|
1589
|
|
|
1590 `button1': The mouse buttons. This means that the specified button was held
|
|
|
1591 `button2': down at the time the event occurred. NOTE: For button-press
|
|
|
1592 `button3': events, the button that was just pressed down does NOT appear in
|
|
|
1593 `button4': the modifiers.
|
|
|
1594 `button5':
|
|
|
1595
|
|
|
1596 Button modifiers are currently ignored when defining and looking up key and
|
|
|
1597 mouse strokes in keymaps. This could be changed, which would allow a user to
|
|
|
1598 create button-chord actions, use a button as a key modifier and do other
|
|
|
1599 clever things.
