-.SH NAME
-event \- Miscellaneous event facilities: define virtual events and generate events
-.SH SYNOPSIS
-\fBevent\fI option \fR?\fIarg arg ...\fR?
-.BE
-.SH DESCRIPTION
-.PP
-The \fBevent\fR command provides several facilities for dealing with
-window system events, such as defining virtual events and synthesizing
-events. The command has several different forms, determined by the
-first argument. The following forms are currently supported:
-.TP
-\fBevent add <<\fIvirtual\fB>>\fI sequence \fR?\fIsequence ...\fR?
-Associates the virtual event \fIvirtual\fR with the physical
-event sequence(s) given by the \fIsequence\fR arguments, so that
-the virtual event will trigger whenever any one of the \fIsequence\fRs
-occurs.
-\fIVirtual\fR may be any string value and \fIsequence\fR may have
-any of the values allowed for the \fIsequence\fR argument to the
-\fBbind\fR command.
-If \fIvirtual\fR is already defined, the new physical event sequences
-add to the existing sequences for the event.
-.TP
-\fBevent delete <<\fIvirtual\fB>> \fR?\fIsequence\fR \fIsequence ...\fR?
-Deletes each of the \fIsequence\fRs from those associated with
-the virtual event given by \fIvirtual\fR.
-\fIVirtual\fR may be any string value and \fIsequence\fR may have
-any of the values allowed for the \fIsequence\fR argument to the
-\fBbind\fR command.
-Any \fIsequence\fRs not currently associated with \fIvirtual\fR
-are ignored.
-If no \fIsequence\fR argument is provided, all physical event sequences
-are removed for \fIvirtual\fR, so that the virtual event will not
-trigger anymore.
-.TP
-\fBevent generate \fIwindow event \fR?\fIoption value option value ...\fR?
-Generates a window event and arranges for it to be processed just as if
-it had come from the window system.
-\fIWindow\fR gives the path name of the window for which the event
-will be generated; it may also be an identifier (such as returned by
-\fBwinfo id\fR) as long as it is for a window in the current application.
-\fIEvent\fR provides a basic description of
-the event, such as \fB<Shift-Button-2>\fR or \fB<<Paste>>\fR.
-If \fIWindow\fR is empty the whole screen is meant, and coordinates
-are relative to the screen.
-\fIEvent\fR may have any of the forms allowed for the \fIsequence\fR
-argument of the \fBbind\fR command except that it must consist
-of a single event pattern, not a sequence.
-\fIOption-value\fR pairs may be used to specify additional
-attributes of the event, such as the x and y mouse position; see
-\fBEVENT FIELDS\fR below. If the \fB\-when\fR option is not specified, the
-event is processed immediately: all of the handlers for the event
-will complete before the \fBevent generate\fR command returns.
-If the \fB\-when\fR option is specified then it determines when the
-event is processed. Certain events, such as key events, require
-that the window has focus to receive the event properly.
-.TP
-\fBevent info \fR?\fB<<\fIvirtual\fB>>\fR?
-Returns information about virtual events.
-If the \fB<<\fIvirtual\fB>>\fR argument is omitted, the return value
-is a list of all the virtual events that are currently defined.
-If \fB<<\fIvirtual\fB>>\fR is specified then the return value is
-a list whose elements are the physical event sequences currently
-defined for the given virtual event; if the virtual event is
-not defined then an empty string is returned.
-.RS
-.PP
-Note that virtual events that are not bound to physical event
-sequences are \fInot\fR returned by \fBevent info\fR.
-.RE
-.SH "EVENT FIELDS"

-.SH "PREDEFINED VIRTUAL EVENTS"
-.PP
-Tk defines the following virtual events for the purposes of
-notification:
-.TP
-\fB<<AltUnderlined>>\fR
-This is sent to widget to notify it that the letter it has underlined
-(as an accelerator indicator) with the \fB\-underline\fR option has
-been pressed in combination with the Alt key. The usual response to
-this is to either focus into the widget (or some related widget) or to
-invoke the widget.
-.TP
-\fB<<Invoke>>\fR
-This can be sent to some widgets (e.g. button, listbox, menu) as an
-alternative to <space>.
-.TP
-\fB<<ListboxSelect>>\fR
-This is sent to a listbox when the set of selected item(s) in the
-listbox is updated.
-.TP
-\fB<<MenuSelect>>\fR
-This is sent to a menu when the currently selected item in the menu
-changes. It is intended for use with context-sensitive help systems.
-.TP
-\fB<<Modified>>\fR
-This is sent to a text widget when the contents of the widget are
-changed.
-.TP
-\fB<<Selection>>\fR
-This is sent to a text widget when the selection in the widget is
-changed.
-.TP
-\fB<<ThemeChanged>>\fR
-This is sent to all widgets when the ttk theme changed. The ttk
-widgets listen to this event and redisplay themselves when it fires.
-The legacy widgets ignore this event.
-.TP
-\fB<<TraverseIn>>\fR
-This is sent to a widget when the focus enters the widget because of a
-user-driven
-.QW "tab to widget"
-action.
-.TP
-\fB<<TraverseOut>>\fR
-This is sent to a widget when the focus leaves the widget because of a
-user-driven
-.QW "tab to widget"
-action.
-.TP
-\fB<<UndoStack>>\fR
-This is sent to a text widget when its undo stack or redo stack becomes
-empty or unempty.
-.TP
-\fB<<WidgetViewSync>>\fR
-This is sent to a text widget when its internal data become obsolete,
-and again when these internal data are back in sync with the widget
-view. The detail field (%d substitution) is either true (when the
-widget is in sync) or false (when it is not).
-.PP

-.SH EXAMPLES
-.SS "MAPPING KEYS TO VIRTUAL EVENTS"
-.PP
-In order for a virtual event binding to trigger, two things must
-happen. First, the virtual event must be defined with the
-\fBevent add\fR command. Second, a binding must be created for
-the virtual event with the \fBbind\fR command.
-Consider the following virtual event definitions:
-.PP
-.CS
-\fBevent add\fR <<Paste>> <Control-y>
-\fBevent add\fR <<Paste>> <Button-2>
-\fBevent add\fR <<Save>> <Control-X><Control-S>
-\fBevent add\fR <<Save>> <Shift-F12>
-if {[tk windowingsystem] eq "aqua"} {
- \fBevent add\fR <<Save>> <Command-s>
-}
-.CE
-.PP
-In the \fBbind\fR command, a virtual event can be bound like any other
-builtin event type as follows:
-.PP
-.CS
-bind Entry <<Paste>> {%W insert [selection get]}
-.CE
-.PP
-The double angle brackets are used to specify that a virtual event is being
-bound. If the user types Control-y or presses button 2, or if
-a \fB<<Paste>>\fR virtual event is synthesized with \fBevent generate\fR,
-then the \fB<<Paste>>\fR binding will be invoked.
-.PP
-If a virtual binding has the exact same sequence as a separate
-physical binding, then the physical binding will take precedence.
-Consider the following example:
-.PP
-.CS
-\fBevent add\fR <<Paste>> <Control-y> <Meta-Control-y>
-bind Entry <Control-y> {puts Control-y}
-bind Entry <<Paste>> {puts Paste}
-.CE
-.PP
-When the user types Control-y the \fB<Control-y>\fR binding
-will be invoked, because a physical event is considered
-more specific than a virtual event, all other things being equal.
-However, when the user types Meta-Control-y the
-\fB<<Paste>>\fR binding will be invoked, because the
-\fBMeta\fR modifier in the physical pattern associated with the
-virtual binding is more specific than the \fB<Control-y\fR> sequence for
-the physical event.
-.PP
-Bindings on a virtual event may be created before the virtual event exists.
-Indeed, the virtual event never actually needs to be defined, for instance,
-on platforms where the specific virtual event would be meaningless or
-ungeneratable.
-.PP
-When a definition of a virtual event changes at run time, all windows
-will respond immediately to the new definition.
-Starting from the preceding example, if the following code is executed:
-.PP
-.CS
-bind Entry <Control-y> {}
-\fBevent add\fR <<Paste>> <Key-F6>
-.CE
-.PP
-the behavior will change such in two ways. First, the shadowed
-\fB<<Paste>>\fR binding will emerge.
-Typing Control-y will no longer invoke the \fB<Control-y>\fR binding,
-but instead invoke the virtual event \fB<<Paste>>\fR. Second,
-pressing the F6 key will now also invoke the \fB<<Paste>>\fR binding.
-.SS "MOVING THE MOUSE POINTER"
-.PP
-Sometimes it is useful to be able to really move the mouse pointer. For
-example, if you have some software that is capable of demonstrating directly
-to the user how to use the program. To do this, you need to
-.QW warp
-the mouse around by using \fBevent generate\fR, like this:
-.PP
-.CS
-for {set xy 0} {$xy < 200} {incr xy} {
- \fBevent generate\fR . <Motion> -x $xy -y $xy -warp 1
- update
- after 50
-}
-.CE
-.PP
-Note that it is usually considered bad style to move the mouse pointer for the
-user because it removes control from them. Therefore this technique should be
-used with caution. Also note that it is not guaranteed to function on all
-platforms.
