NAME
tixDirTree - Create and manipulate tixDirTree widgets
SYNOPSIS
tixDirTree pathName ?options?
SUPER-CLASS
The TixDirTree class is derived from the TixScrolledHList
class and inherits all the commands, options and subwid-
gets of its super-class.
STANDARD OPTIONS
TixDirTree supports all the standard options of a frame
widget. See the options(n) manual entry for details on
the standard options.
WIDGET-SPECIFIC OPTIONS
Name: browseCmd
Class: BrowseCmd
Switch: -browsecmd
Specifies a command to call whenever the user
browses on a directory (usually by single-clicking
on the name of the directory). The command is
called with one argument, the complete pathname of
the directory.
Name: command
Class: Command
Switch: -command
Specifies the command to be called when the user
activates on a directory (usually by double-click-
ing on the name of the directory). The command is
called with one argument, the complete pathname of
the directory.
Name: dircmd
Class: DirCmd
Switch: -dircmd
Specifies the TCL command to be called when a
directory listing is needed for a particular direc-
tory. If this option is not specified, by default
the DirTree widget will attempt to read the direc-
tory as a Unix directory. On special occasions, the
application programmer may want to supply a special
method for reading directories: for example, when
he needs to list remote directories. In this case,
the -dircmd option can be used. The specified com-
mand accepts two arguments: the first is the name
of the directory to be listed; the second is a
Boolean value indicating whether hidden sub-direc-
tories should be listed. This command returns a
list of names of the sub-directories of this direc-
tory. For example:
proc read_dir {dir show_hidden} {
if {$dir == "C:\"} {
return {DOS NORTON WINDOWS}
} else {
return {}
}
}
Name: disableCallback
Class: DisableCallback
Switch: -disablecallback
A boolean value indicating whether callbacks should
be disabled. When set to true, the TCL command
specified by the -command option is not executed
when the -value of the DirTree widget changes.
Name: showHidden
Class: ShowHidden
Switch: -showhidden
Specifies whether hidden directories should be
shown. By default, a directory name starting with a
period "." is considered as a hidden directory.
This rule can be overridden by supplying an alter-
native -dircmd option.
Name: value
Class: Value
Switch: -value
Alias: -directory
Specifies the name of the current directory to be
displayed in the DirTree widget.
SUBWIDGETS
Name: hlist
Class: TixHList
The hierarchical listbox that displays the direc-
tory listing.
Name: hsb
Class: Scrollbar
The horizontal scrollbar subwidget.
Name: vsb
Class: Scrollbar
The vertical scrollbar subwidget.

DESCRIPTION
The tixDirTree command creates a new window (given by the
pathName argument) and makes it into a DirTree widget.
Additional options, described above, may be specified on
the command line or in the option database to configure
aspects of the DirTree such as its cursor and relief.
The DirTree widget displays a list view of a directory,
its previous directories and its sub-directories. The user
can choose one of the directories displayed in the list or
change to another directory.
WIDGET COMMANDS
The tixDirTree command creates a new Tcl command whose
name is the same as the path name of the DirTree'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 DirTree widget's path name. Option and the args deter-
mine the exact behavior of the command. The following com-
mands are possible for DirTree widgets:
pathName cget option
Returns the current value of the configuration
option given by option. Option may have any of the
values accepted by the tixDirTree command.
pathName chdir dir
Change the current directory to dir.
pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the
widget. If no option is specified, returns a list
describing all of the available options for path-
Name (see Tk_ConfigureInfo for information on the
format of this list). If option is specified with
no value, then the command returns a list describ-
ing the one named option (this list will be identi-
cal to the corresponding sublist of the value
returned if no option is specified). If one or
more option-value 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. Option may have any of
the values accepted by the tixDirTree command.
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.
BINDINGS
The mouse and keyboard bindings of the DirTree widget are
the same as the bindings of the HList widget.
