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
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 directory). 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-click
ing on the name of the directory). 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 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
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 {}
}
}
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 considered as a hidden directory.
This rule can be overridden by supplying an alter
native -dircmd option.
Command-Line Name:-value or -directory
Database Name: value
Database Class: Value
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
options.
BINDINGS
The mouse and keyboard bindings of the DirTree widget are
the same as the bindings of the HList widget.
