\fBtixDirTree\fI \fIpathName ?\fIoptions\fR?

'

'

'----------------------------------------------------------------------

.PP

.SH SUPER-CLASS

The \fBTixDirTree\fR class is derived from the \fBTixScrolledHList\fR

class and inherits all the commands, options and subwidgets of its

super-class.

'

'----------------------------------------------------------------------

.SH "STANDARD OPTIONS"

'

\fBTixDirTree\fR supports all the standard options of a frame widget.

See the \fBoptions(n)\fR manual entry for details on the standard options.

Name:           \fBbrowseCmd\fR

Class:          \fBBrowseCmd\fR

Switch:         \fB\-browsecmd\fR

.fi

.IP

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.

'----------END

Name:           \fBcommand\fR

Class:          \fBCommand\fR

Switch:         \fB\-command\fR

.fi

.IP

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.

'----------END

'

'----------BEGIN

.LP

.nf

Name:           \fBdircmd\fR

Class:          \fBDirCmd\fR

Switch:         \fB\-dircmd\fR

.fi

.IP

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

\fB\-dircmd\fR 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:

\fC

.nf

 proc read_dir {dir show_hidden} {

     if {$dir == "C:\\"} {

         return {DOS NORTON WINDOWS}

     } else {

         return {}

     }

 }

Class:          \fBDisableCallback\fR

Switch:         \fB\-disablecallback\fR

.fi

.IP

A boolean value indicating whether callbacks should be disabled. When

set to true, the TCL command specified by the \fB\-command\fR option

is not executed when the \fB\-value\fR of the DirTree widget

changes.

'----------END

Class:          \fBShowHidden\fR

Switch:         \fB\-showhidden\fR

.fi

.IP

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

\fB\-dircmd\fR option.

.SH DESCRIPTION

'

.PP

'

The \fBtixDirTree\fR command creates a new window (given by the

\fIpathName\fR 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.

'

'

'----------------------------------------------------------------------

.SH WIDGET COMMANDS

.PP

'

The \fBtixDirTree\fR 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:

'

.DS C

'

\fIpathName option \fR?\fIarg arg ...\fR?

.PP

.DE

'

\fIPathName\fR is the name of the command, which is the same as the

DirTree widget's path name. \fIOption\fR and the \fIarg\fRs

determine the exact behavior of the command. The following commands

are possible for DirTree widgets:

'

.TP

\fIpathName \fBcget\fR \fIoption\fR

'

Returns the current value of the configuration option given by

\fIoption\fR. \fIOption\fR may have any of the values accepted by the

\fBtixDirTree\fR command.

'

.TP

\fIpathName \fBchdir\fR \fIdir\fR

'

Change the current directory to \fIdir\fR.

'

'

.TP

'

\fIpathName \fBconfigure\fR ?\fIoption\fR? \fI?value option value ...\fR?

'

Query or modify the configuration options of the widget.  If no

\fIoption\fR is specified, returns a list describing all of the

available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for

information on the format of this list). If \fIoption\fR is specified

with no \fIvalue\fR, 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 \fIoption\fR is specified).  If

one or more \fIoption\-value\fR 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.  \fIOption\fR may have

any of the values accepted by the \fBtixDirTree\fR command.

'

'

.TP

\fIpathName \fBsubwidget \fI name ?args?\fR

'

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.

'

'

'

'----------------------------------------------------------------------

.SH BINDINGS

.PP

'

The mouse and keyboard bindings of the DirTree widget are the same as

the bindings of the HList widget.
