SYNOPSIS
tixDirList pathName ?options?SUPER-CLASS
The TixDirList class is derived from the TixScrolledHList class and inherits all the commands, options and subwidgets of its super-class.STANDARD OPTIONS
TixDirList 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 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. [ -command command Command ] Specifies the command to be called when the user activates on a directory (usually by double-clicking on the name of the directory). The command is called with one argument, the complete pathname of the directory. [ -dircmd dircmd 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 DirList 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 {}
}
}
[ -disablecallback 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 DirList widget
changes.
[ -showhidden showHidden 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 alternative
-dircmd option.
[ -root root Root ]
Specifies the name of the root directory. Usually this is "/"
under Unix machines, but can be changed to "C:\" in DOS environments.
[ -rootname rootName RootNAme ]
Specifies a text string to display at the root directory. If
unspecified, the text string will be the same as the string specified
by -root.
Name: value Class: Value Switch: -value Alias: -directory
- Specifies the name of the current directory to be displayed in the DirList widget.
SUBWIDGETS

- 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 tixDirList command creates a new window (given by the pathName argument) and makes it into a DirList widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the DirList such as its cursor and relief.
The DirList 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 tixDirList command creates a new Tcl command whose name is the same as the path name of the DirList'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 cget option
- Returns the current value of the configuration option given by option. Option may have any of the values accepted by the tixDirList 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 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 tixDirList 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 DirList widget are the same as the bindings of the HList widget.
