NAME

       tixCheckList - Create and manipulate tixCheckList widgets

SYNOPSIS

       tixCheckList pathName ?options?

SUPER-CLASS

       The  TixCheckList  class  is derived from the TixTree class and inherits all the commands,
       options and subwidgets of its super-class.

STANDARD OPTIONS

       TixCheckList supports all the standard options of  a  frame  widget.  See  the  options(n)
       manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS

       [-browsecmd browseCmd]  Specifies  a command to call whenever the user browses on an entry
       (usually by single-clicking on the entry). The command is called with  one  argument,  the
       pathname  of  the entry.  [-command command] Specifies a command to call whenever the user
       activates an entry (usually by double-clicking on the entry). The command is  called  with
       one  argument, the pathname of the entry.  [-radio radio] A Boolean value. If set to true,
       the user can select at most one item at a time; if set to false, the user  can  select  as
       many items as possible.

SUBWIDGETS

       Name:          hlist
       Class:         TixHList

              The hierarchical listbox that displays the CheckList.

       Name:          hsb
       Class:         Scrollbar

              The horizontal scrollbar subwidget.

       Name:          vsb
       Class:         Scrollbar

              The vertical scrollbar subwidget.

DESCRIPTION

       The  tixCheckList  command creates a new window (given by the pathName argument) and makes
       it into a CheckList widget.  Additional options, described above, may be specified on  the
       command  line  or in the option database to configure aspects of the CheckList widget such
       as its cursor and relief.

       The CheckList widget displays a list of items to be selected by the user.  CheckList  acts
       similarly  to  the Tk checkbutton or radiobutton widgets, except it is capable of handling
       many more items than checkbuttons or radiobuttons.

       The items are contained in the hlist subwidget.  Each item may be in one of the  following
       status:  on  (indicated  by  a  check  bitmap),  off (indicated by a cross bitmap) default
       (indicated by a gray box bitmap) or none, in which case the item will not  be  accompanied
       by  a bitmap. The items whose status is on, off or default are called the selectable items
       and can be checked or crossed by the user. All selectable entries  must  be  of  the  type
       imagetext.

       The  items whose status is none cannot be checked or crossed by the user; usually they are
       included in the hlist subwidget only for explanation purposes or as separators.

       Initially, all the items have a none status. To make an item selectable, you can call  the
       setstatus command to change its status (see below).

       Notice  that  CheckList  is  a  subclass  of  the TixTree widget and thus is is capable of
       displaying a hierarchy of selectable entries. When necessary, you  can  call  the  setmode
       method (see TixTree(n)) to define the hierarchical structure of the selectable entries.

WIDGET COMMANDS

       The tixCheckList command creates a new Tcl command whose name is the same as the path name
       of the CheckList's window.  This command may be used to invoke various operations  on  the
       widget. It has the following general form:
              pathName option ?arg arg ...?
       PathName  is  the  name  of  the command, which is the same as the CheckList widget's path
       name. Option and the args determine the exact  behavior  of  the  command.  The  following
       commands are possible for CheckList widgets:

       pathName getselection ?status?
              Returns  a  list  of items whose status matches status. If status is not specified,
              the list of items in the "on" status will be returned.

       pathName getstatus entryPath
              Returns the current status of entryPath.

       pathName setstatus entryPath status
              Sets the status of entryPath to be status. A bitmap will be displayed next  to  the
              entry its status is on, off or default.

       pathName subwidget  name ?args?
              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.

EXAMPLE

       This example creates several choices for the user to select.

       set  c  [tixCheckList .c] $c subwidget hlist add choice1 -itemtype imagetext -text Choice1
       $c subwidget hlist add choice2 -itemtype imagetext -text Choice2 $c  subwidget  hlist  add
       choice3 -itemtype imagetext -text Choice3 $c setstatus choice1 on $c setstatus choice2 off
       $c setstatus choice3 off pack $c

BINDINGS

       The basic mouse and keyboard bindings of the CheckList widget are the same as the bindings
       of the TixTree widget.

       In  addition,  the  status of the entries in the CheckList are toggled under the following
       conditions:

       [1]    When the user press the mouse button over an entry.

       [2]    When the user press the <space> key over an entry.

       [3]    When the user press the <Return> key over an entry.
