.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
tk_chooseDirectory \- pops up a dialog box for the user to select a directory.
.SH SYNOPSIS
\fBtk_chooseDirectory \fR?\fIoption value ...\fR?
.BE
.SH DESCRIPTION
.PP
The procedure \fBtk_chooseDirectory\fR pops up a dialog box for the
user to select a directory. The following \fIoption\-value\fR pairs are
possible as command line arguments:
.\" OPTION: -command
.TP
\fB\-command\fI string\fR
.
Specifies the prefix of a Tcl command to invoke when the user closes the
dialog after having selected an item. This callback is not called if the
user cancelled the dialog. The actual command consists of \fIstring\fR
followed by a space and the value selected by the user in the dialog. This
is only available on macOS.
.\" OPTION: -initialdir
.TP
\fB\-initialdir\fI dirname\fR
.
Specifies that the directories in \fIdirectory\fR should be displayed
when the dialog pops up. If this parameter is not specified,
the initial directory defaults to the current working directory
on non-Windows systems and on Windows systems prior to Vista.
On Vista and later systems, the initial directory defaults to the last
user-selected directory for the application. If the
parameter specifies a relative path, the return value will convert the
relative path to an absolute path.
.\" OPTION: -message
.TP
\fB\-message\fI string\fR
.
Specifies a message to include in the client area of the dialog.
This is only available on macOS.
.\" OPTION: -mustexist
.TP
\fB\-mustexist\fI boolean\fR
.
Specifies whether the user may specify non-existent directories.  If
this parameter is true, then the user may only select directories that
already exist.  The default value is \fIfalse\fR.
.\" OPTION: -parent
.TP
\fB\-parent\fI window\fR
.
Makes \fIwindow\fR the logical parent of the dialog. The dialog
is displayed on top of its parent window. On macOS, this
turns the file dialog into a sheet attached to the parent window.
.\" OPTION: -title
.TP
\fB\-title\fI titleString\fR
.
Specifies a string to display as the title of the dialog box. If this
option is not specified, then a default title will be displayed.
