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 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
Command-Line Name:-browsecmd
Database Name: browseCmd
Database Class: BrowseCmd
Specifies a command to call whenever the user browses on a
directory (usually by single-clicking on the name of the direc-
tory). The command is called with one argument, the complete
pathname of the directory.
Command-Line Name:-command
Database Name: command
Database Class: Command
Specifies the command to be called when the user activates on a
directory (usually by double-clicking on the name of the direc-
tory). The command is called with one argument, the complete
pathname of the directory.
Command-Line Name:-dircmd
Database Name: dircmd
Database Class: DirCmd
Specifies 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 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 command accepts two arguments: the first is the name
of the directory to be listed; the second is a Boolean value
indicating 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 {}
}
}
Command-Line Name:-disablecallback
Database Name: disableCallback
Database Class: 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.
Command-Line Name:-showhidden
Database Name: showHidden
Database Class: ShowHidden
Specifies whether hidden directories should be shown. By
default, a directory name starting with a period "." is consid-
ered as a hidden directory. This rule can be overridden by sup-
plying an alternative -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 directory 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 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.
