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

975 `button-release', `misc-user' or `motion'. If TYPE is nil, it
|
|

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

979 returned by `event-properties'. The following properties are
|
|
|
980 allowed:
|
|
|
981
|
|
|
982 channel -- The event channel, a frame or a console. For
|
|
|
983 button-press, button-release, misc-user and motion events,
|
|
|
984 this must be a frame. For key-press events, it must be
|
|
|
985 a console. If channel is unspecified, it will be set to
|
|
|
986 the selected frame or selected console, as appropriate.
|
|
|
987 key -- The event key, a symbol or character. Allowed only for
|
|
|
988 keypress events.
|
|
|
989 button -- The event button, integer 1, 2 or 3. Allowed for
|
|
|
990 button-press, button-release and misc-user events.
|
|
|
991 modifiers -- The event modifiers, a list of modifier symbols. Allowed
|
|
|
992 for key-press, button-press, button-release, motion and
|
|
|
993 misc-user events.
|
|
|
994 function -- Function. Allowed for misc-user events only.
|
|
|
995 object -- An object, function's parameter. Allowed for misc-user
|
|
|
996 events only.
|
|
|
997 x -- The event X coordinate, an integer. This is relative
|
|
|
998 to the left of CHANNEL's root window. Allowed for
|
|
|
999 motion, button-press, button-release and misc-user events.
|
|
|
1000 y -- The event Y coordinate, an integer. This is relative
|
|
|
1001 to the top of CHANNEL's root window. Allowed for
|
|
|
1002 motion, button-press, button-release and misc-user events.
|
|
|
1003 timestamp -- The event timestamp, a non-negative integer. Allowed for
|
|
|
1004 all types of events. If unspecified, it will be set to 0
|
|
|
1005 by default.
|
|
|
1006
|
|
|
1007 For event type `empty', PLIST must be nil.

1008 `button-release', or `motion'. If TYPE is left out, it defaults to

1009 `empty'.

2137 arguments ``mean'' -- for example, the number 9 is converted to the

2139
|

2153 CONSOLE affects whether the high bit is interpreted as a meta

2160 Lisp character object type can encode.

2652 Return a list of symbols, the names of the modifier keys and buttons
|
|
428
|
2653 which were down when the given mouse or keyboard event was produced.
|
|
442
|
2654 See also the function `event-modifier-bits'.
|
|
|
2655
|
|
|
2656 The possible symbols in the list are
|
|
|
2657
|
|
|
2658 `shift': The Shift key. Will not appear, in general, on key events
|
|
|
2659 where the keysym is an ASCII character, because using Shift
|
|
|
2660 on such a character converts it into another character rather
|
|
|
2661 than actually just adding a Shift modifier.
|
|
|
2662
|
|
|
2663 `control': The Control key.
|
|
|
2664
|
|
|
2665 `meta': The Meta key. On PC's and PC-style keyboards, this is generally
|
|
|
2666 labelled \"Alt\"; Meta is a holdover from early Lisp Machines and
|
|
|
2667 such, propagated through the X Window System. On Sun keyboards,
|
|
|
2668 this key is labelled with a diamond.
|
|
|
2669
|
|
|
2670 `alt': The \"Alt\" key. Alt is in quotes because this does not refer
|
|
|
2671 to what it obviously should refer to, namely the Alt key on PC
|
|
|
2672 keyboards. Instead, it refers to the key labelled Alt on Sun
|
|
|
2673 keyboards, and to no key at all on PC keyboards.
|
|
|
2674
|
|
|
2675 `super': The Super key. Most keyboards don't have any such key, but
|
|
|
2676 under X Windows using `xmodmap' you can assign any key (such as
|
|
|
2677 an underused right-shift, right-control, or right-alt key) to
|
|
|
2678 this key modifier. No support currently exists under MS Windows
|
|
|
2679 for generating these modifiers.
|
|
|
2680
|
|
|
2681 `hyper': The Hyper key. Works just like the Super key.
|
|
|
2682
|
|
|
2683 `button1': The mouse buttons. This means that the specified button was held
|
|
|
2684 `button2': down at the time the event occurred. NOTE: For button-press
|
|
|
2685 `button3': events, the button that was just pressed down does NOT appear in
|
|
|
2686 `button4': the modifiers.
|
|
|
2687 `button5':
|
|
|
2688
|
|
|
2689 Button modifiers are currently ignored when defining and looking up key and
|
|
|
2690 mouse strokes in keymaps. This could be changed, which would allow a user to
|
|
|
2691 create button-chord actions, use a button as a key modifier and do other
|
|
|
2692 clever things.
