<div class="textblock"><p>A standard dialog for confirmation or to get simple user input. </p>
<p>The message box shows a message in a dialog window, with a number of buttons. These buttons may only be standard buttons.</p>
<p>There are two distinct ways for using a MessageBox, which reflect the two ways of dealing with a <a class="el" href="classWt_1_1Ext_1_1Dialog.html" title="A dialog emulates a modal window that blocks the user-interface.">Dialog</a> box.</p>
<p>The easiest way is using the static <a class="el" href="classWt_1_1WWidget.html#a52dcef5a385ddfa0a8c3e6c20000f181" title="Shows the widget.">show()</a> method, which shows a message box, blocks the current thread, and returns the button that was pressed by the user. Since this uses the <a class="el" href="classWt_1_1Ext_1_1Dialog.html#a1dbf3f23fde44807110abe3cf43f7944" title="Execute the dialog in a recursive event loop.">Dialog::exec()</a>, it suffers from the same scalability issues.</p>
<p>The more elaborate way is by creating a <a class="el" href="classWt_1_1Ext_1_1MessageBox.html" title="A standard dialog for confirmation or to get simple user input.">MessageBox</a>, and connecting the buttonClicked signal to a method. This method then interpretes the result and deletes the message box.</p>
<p>The API is slightly different from the <a class="el" href="classWt_1_1WMessageBox.html" title="A standard dialog for confirmation or to get simple user input.">WMessageBox</a> API: </p>
<ul>
<li>
no support for non-standard buttons (<a class="el" href="classWt_1_1WMessageBox.html#a9d07bb99d17c38128c79f9c7ecd42963" title="Add a custom button with given text.">WMessageBox::addButton()</a>), or access to buttons (<a class="el" href="classWt_1_1WMessageBox.html#a0e95f906d321b5c5cb574abc25716aec" title="Returns the button widget for the given standard button.">WMessageBox::button()</a>). </li>
<li>
supports only Yes, No, Ok and Cancel buttons. </li>
<li>
supports more JavaScript like standard functionality, to prompt for input (<a class="el" href="classWt_1_1Ext_1_1MessageBox.html#a4c551e90aea08438544ddbf2f3197133" title="Show a single-line input field.">enablePrompt()</a>, <a class="el" href="classWt_1_1Ext_1_1MessageBox.html#ade8dec9c2364c85ed42fc0cdb3bbae53" title="Show a multi-line input field.">enableTextArea()</a>). </li>
