6 <h1>class <tt>ModalDialog(Dialog)</tt></h1>
7 The ModalDialog class is a subclass of <a href="Dialog.html">Dialog</a>
8designed for modal dialogs. It has a default style of <tt>'modal_dialog'</tt>
9and provides facilities for presenting the dialog modally.<br>
10 <br>
11 While a ModalDialog is active, interaction with other parts of the application
12is prevented. Other windows cannot be activated, application-wide menu commands
13other than those used by the dialog itself are not enabled, and unhandled
14events and messages are not forwarded to the application.<br>
15 <h2>Constructor</h2>
16 <blockquote> <dl>
17 <dt><tt>ModalDialog(style</tt> <tt>=</tt> <tt>'modal_dialog',</tt></dt>
18 <dt><tt> </tt><tt>closable</tt> <tt>=</tt> <tt>False,</tt> <tt>resizable</tt> <tt>=</tt> <tt>False,</tt> <tt>zoomable</tt> = <tt>False</tt><tt>,</tt></dt>

21for the <tt>movable</tt> and <tt>hidable</tt> options are platform-dependent.</dd>

24 <h2>Methods</h2>
25 <blockquote> <dl>
26 <dt><tt>present()</tt></dt>
27 <dd>Present the dialog modally. The dialog is shown and a nested event
28loop is entered which prevents interaction with any other part of the application.
29This method retains control until the dialog's <tt>dismiss()</tt> method is
30called. The dialog is then hidden and the <span style="font-family: monospace;">present()</span> method returns with the value passed to <tt>dismiss()</tt>.<br>
31 </dd>

By default, this method is called in response to pressing a <a href="Button.html#DefaultButton">DefaultButton</a> or a Return/Enter key event.<br><br></dd><dt style="font-family: monospace;">cancel()</dt><dd>Dismisses the dialog with the value <span style="font-family: monospace;">False</span>.
