SUPER-CLASS
The TixDirTree class is derived from the TixScrolledHList class and
inherits all the commands, options and subwidgets 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
[-browsecmd 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 path‐
name of the directory. [-command 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 argu‐
ment, the complete pathname of the directory. [-dircmd dircmd] Speci‐
fies the TCL command to be called when a directory listing is needed
for a particular directory. If this option is not specified, by default
the DirTree widget will attempt to read the directory as a Unix direc‐
tory. On special occasions, the application programmer may want to sup‐
ply 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 command accepts two arguments: the first is the
name of the directory to be listed; the second is a Boolean value indi‐
cating whether hidden sub-directories should be listed. This command
returns a list of names of the sub-directories of this directory. For
example: proc read_dir {dir show_hidden} {
if {$dir == "C:\"} {
return {DOS NORTON WINDOWS}
} else {
return {}
} } [-disablecallback 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. [-showhidden showHidden] Specifies whether
hidden directories should be shown. By default, a directory name start‐
ing with a period "." is considered as a hidden directory. This rule
can be overridden by supplying an alternative -dircmd option.

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 determine the exact behavior of
the command. The following commands 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 avail‐
able options for pathName (see Tk_ConfigureInfo for information
on the format of this list). If option is specified with no
value, 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 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 sub‐
widget 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.
