<h1>Directory Dialog</h1>

<br>
<br>
<h2>Creating the Dialog</h2>
Create a Directory Dialog by calling dialog.directoryDialog
with the two arguments shown in the following table.<br>
<br>
<table cellpadding="2" cellspacing="2" border="1" width="80%">
<tbody>
<tr>
<td valign="top"><b>Argument</b><br>
</td>
<td valign="top"><b>Data type/notes</b><br>
</td>
</tr>
<tr>
<td valign="top">self<br>
</td>
<td valign="top">the window (background) that is the parent
for the dialog<br>
</td>
</tr>
<tr>
<td valign="top">
<p>message</p>
</td>
<td valign="top">
<p>quoted string that provides a prompt to be displayed inside the
dialog box </p>
</td>
</tr>
<tr>
<td valign="top"> path<br>
</td>
<td valign="top">quoted string providing the initial directory
in which to open the dialog. Providing an invalid or non-existent directory
places the user at the top level of the directory structure. If this string
is empty, the directory dialog opens to the top-level directory.
</td>
</tr>
</tbody>
</table>
<br>
<b>Example:<br>
<br>
</b>Above dialog was created with this line of code:<br>
<br>
<code>result = dialog.directoryDialog(self, 'Choose a directory',
'')</code><br>
<br>
Since the directory parameter is empty, the directory dialog opens at the top
level of the directory structure as shown in the figure. To cause the directory
dialog to open on a directory called, e.g., C:\PYTHON23, you would write:
<p><code>result = dialog.directoryDialog(self, 'Choose a directory', 'C:\\Python23')<br>
</code><br>
</p>
<h2>Interacting With the Dialog</h2>
The directoryDialog component returns two values, stored as elements
of the Python dictionary called "results" returned by all PythonCard
dialogs. These results are as shown in the following table.<br>
<br>
<table cellpadding="2" cellspacing="2" border="1" width="80%">
<tbody>
<tr>
<td valign="top"><b>Name of value</b><br>
</td>
<td valign="top"><b>Description</b><br>
</td>
</tr>
<tr>
<td valign="top">accepted<br>
</td>
<td valign="top">True = user clicked OK<br>
False = user clicked Cancel<br>
</td>
</tr>
<tr>
<td valign="top">path<br>
</td>
<td valign="top">string containing the full path to the
chosen directory<br>
</td>
</tr>
</tbody>
</table>
<br>
<b>Example:<br>
<br>
</b>The sample dialog shown at the top of this page returns the
following results if the user navigates to the C: drive and picks the
directory called "pycode."<b><br>
<br>
</b>accepted: True<br>
path: C:\\pycode<br>
