.SH NAME
tixPopupMenu \- Create and manipulate tixPopupMenu widgets
'\"
'\"
'\"
'\"----------------------------------------------------------------------
.SH SYNOPSIS
\fBtixPopupMenu \fIpathName \fR?\fIoptions\fR?
'\"
'\"
'\"----------------------------------------------------------------------
.SH SUPER-CLASS
The \fBtixPopupMenu\fR class is derived from the \fBTixShell\fR
class and inherits all the commands, options and subwidgets of its
super-class.
'\"
'\"----------------------------------------------------------------------
.SH "STANDARD OPTIONS"
'\"
The PopupMenu widget supports all the standard options of a frame widget.
See the \fBoptions(n)\fR manual entry for details on the standard options.
'\"
'\"
'\"----------------------------------------------------------------------
.SH "WIDGET-SPECIFIC OPTIONS"
'\"
'\"
'\"----------BEGIN
.OP \-buttons buttons Buttons
A Tcl list that specifies the mouse button(s) and key modifier(s) that
bring up the popup menu. Each element of this list is in turn a list
that contains two elements: the first element is an integer that
indicates the
mouse button that brings up the popup menu; the second element
specifies the key modifiers that should be used in conjunction with
the mouse button. For example, the value \fB{{1 {Control Meta}} {3
{Any}}}\fR specifies that the popup menu can be popped up by (a)
pressing mouse button 1 with either the Control or the Meta key or (b)
pressing mouse button 3 with any key modifier. The default value is
\fB{{3 {Any}}}\fR: only mouse button 3 brings up the popup menu.
'\"----------END
'\"
'\"----------BEGIN
.OP \-postcmd postCmd PostCmd
Specifies a command to be evaluated just before the menu is about to
pop-up. This command is called with two default arguments: the root
x-y coordinates where the user has pressed the mouse button. This
command must return a boolean value: a false indicates that the menu
shouldn't be popped up at this point; a true indicates that the menu
should be popped up. This option can be used to find out where the
user has pressed the mouse-button and optionally disable the popup
menu over certain screen areas.
'\"----------END
'\"
'\"----------BEGIN
.OP \-spring spring Spring
When set to \fBtrue\fR, the menu will be automatically popped down if
the user releases the mouse button outside of the menu and no menu
commands will be invoked. This makes it easy for the user to cancel
the popup menu without pressing the Escape key. The default value is
\fBtrue\fR.
'\"----------END
'\"
'\"----------BEGIN
.OP \-state state State
Must be either \fBdisabled\fR or \fBnormal\fR. The PopupMenu widget will not
pop up unless its \fB\-state\fR is set to \fBnormal\fR.
'\"----------END
'\"
'\"
'\"----------BEGIN
.OP \-title title Title
Specifies a text string to display inside the \fBmenubutton\fR
subwidget, as the title of this PopupMenu.
'\"----------END
'\"
'\"----------------------------------------------------------------------

.SH DESCRIPTION
'\"
.PP
'\"
The \fBtixPopupMenu\fR command creates a new window (given by the
\fIpathName\fR argument) and makes it into a PopupMenu widget.
Additional options, described above, may be specified on the command
line or in the option database to configure aspects of the
PopupMenu widget such as its cursor and relief.
The Tix PopupMenu widget can be used as a replacement of the
\fBtk_popup\fR command. The advantage of the Tix PopupMenu widget is
it requires less application code to manipulate. Also, it provides a
title for the popup menu, which is not available from \fBtk_popup\fR.
'\"
'\"----------------------------------------------------------------------
.SH WIDGET COMMANDS
.PP
'\"
The \fBtixPopupMenu\fR command creates a new Tcl command whose name is
the same as the path name of the PopupMenu widget's window. This
command may be used to invoke various operations on the widget. It has
the following general form:
'\"
.RS
.CS
'\"
\fIpathName option \fR?\fIarg arg ...\fR?
.CE
.RE
'\"
\fIPathName\fR is the name of the command, which is the same as the
PopupMenu widget's path name. \fIOption\fR and the \fIarg\fRs
determine the exact behavior of the command. The following commands
are possible for PopupMenu widgets:
.TP
\fIpathName \fBbind \fIwidget \fR?\fIwidget ...\fR?
'\"
Binds this PopupMenu to one or more \fIwidgets\fR. The PopupMenu
will be activated when the user presses the right mouse button over
these \fIwidgets\fR.
'\"
.TP
\fIpathName \fBcget\fR \fIoption\fR
'\"
Returns the current value of the configuration option given by
\fIoption\fR. \fIOption\fR may have any of the values accepted by the
\fBtixPopupMenu\fR command.
'\"
.TP
\fIpathName \fBconfigure\fR ?\fIoption\fR? \fI?value option value ...\fR?
'\"
Query or modify the configuration options of the widget. If no
\fIoption\fR is specified, returns a list describing all of the
available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
information on the format of this list). If \fIoption\fR is specified
with no \fIvalue\fR, then the command returns a list describing the
one named option (this list will be identical to the corresponding
sublist of the value returned if no \fIoption\fR is specified). If
one or more \fIoption\-value\fR pairs are specified, then the command
modifies the given widget option(s) to have the given value(s); in
this case the command returns an empty string. \fIOption\fR may have
any of the values accepted by the \fBtixPopupMenu\fR command.
'\"
'\"
.TP
\fIpathName \fBpost \fIwidget x y\fR
'\"
Posts the PopupMenu inside the \fIwidget\fR at the coordinate
\fIx\fR,\fIy\fR.
'\"
'\"
.TP
\fIpathName \fBunbind \fIwidget \fR?\fIwidget ...\fR?
'\"
Cancels the PopupMenu's binding with the \fIwidget(s)\fR.
'\"
'\"
.TP
\fIpathName \fBsubwidget \fI name ?args?\fR
'\"
When no options are given, this command returns the pathname of the
subwidget of the specified name.
When options are given, the widget command of the specified subwidget
will be called with these options.
