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
|
|
|
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.
|
|
|
399 key -- The event key, a symbol or character. Allowed only for
|
|
|
400 keypress events.
|
|
|
401 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
402 button-press, button-release and misc-user events.
|
|
|
403 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
|
404 for key-press, button-press, button-release, motion and
|
|
|
405 misc-user events.
|
|
|
406 function -- Function. Allowed for misc-user events only.
|
|
|
407 object -- An object, function's parameter. Allowed for misc-user
|
|
|
408 events only.
|
|
|
409 x -- The event X coordinate, an integer. This is relative
|
|
|
410 to the left of CHANNEL's root window. Allowed for
|
|
|
411 motion, button-press, button-release and misc-user events.
|
|
|
412 y -- The event Y coordinate, an integer. This is relative
|
|
|
413 to the top of CHANNEL's root window. Allowed for
|
|
|
414 motion, button-press, button-release and misc-user events.
|
|
|
415 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
|
416 all types of events. If unspecified, it will be set to 0
|
|
|
417 by default.
|
|
|
418
|
|
|
419 For event type `empty', PLIST must be nil.

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

1160 KEY-DESCRIPTION is the first argument, and the event to fill in is the

1161 second. This function contains knowledge about what various kinds of

1162 arguments ``mean'' -- for example, the number 9 is converted to the

1174 If KEY-DESCRIPTION is an integer or character, the high bit may be

1176 in lots of places.) If USE-CONSOLE-META-FLAG is nil, this will always

1177 be the case. If USE-CONSOLE-META-FLAG is non-nil, the `meta' flag for

1178 CONSOLE affects whether the high bit is interpreted as a meta

1179 key. (See `set-input-mode'.) If you don't want this silly meta

1180 interpretation done, you should pass in a list containing the

1181 character.

1182
|

1183 Beware that character-to-event and event-to-character are not strictly

1184 inverse functions, since events contain much more information than the
|

444
|
1185 Lisp character object type can encode.

1599
|
|
|
1600 `shift': The Shift key. Will not appear, in general, on key events
|
|
|
1601 where the keysym is an ASCII character, because using Shift
|
|
|
1602 on such a character converts it into another character rather
|
|
|
1603 than actually just adding a Shift modifier.
|
|
|
1604
|
|
|
1605 `control': The Control key.
|
|
|
1606
|
|
|
1607 `meta': The Meta key. On PC's and PC-style keyboards, this is generally
|
|
|
1608 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and
|
|
|
1609 such, propagated through the X Window System. On Sun keyboards,
|
|
|
1610 this key is labelled with a diamond.
|
|
|
1611
|
|
|
1612 `alt': The \"Alt\" key. Alt is in quotes because this does not refer
|
|
|
1613 to what it obviously should refer to, namely the Alt key on PC
|
|
|
1614 keyboards. Instead, it refers to the key labelled Alt on Sun
|
|
|
1615 keyboards, and to no key at all on PC keyboards.
|
|
|
1616
|
|
|
1617 `super': The Super key. Most keyboards don't have any such key, but
|
|
|
1618 under X Windows using `xmodmap' you can assign any key (such as
|
|
|
1619 an underused right-shift, right-control, or right-alt key) to
|
|
|
1620 this key modifier. No support currently exists under MS Windows
|
|
|
1621 for generating these modifiers.
|
|
|
1622
|
|
|
1623 `hyper': The Hyper key. Works just like the Super key.
|
|
|
1624
|
|
|
1625 `button1': The mouse buttons. This means that the specified button was held
|
|
|
1626 `button2': down at the time the event occurred. NOTE: For button-press
|
|
|
1627 `button3': events, the button that was just pressed down does NOT appear in
|
|
|
1628 `button4': the modifiers.
|
|
|
1629 `button5':
|
|
|
1630
|
|
|
1631 Button modifiers are currently ignored when defining and looking up key and
|
|
|
1632 mouse strokes in keymaps. This could be changed, which would allow a user to
|
|
|
1633 create button-chord actions, use a button as a key modifier and do other
|
|
|
1634 clever things.
