a layout that is appropriate to the current widget style.</p>
<p>Dialogs and message boxes typically present buttons in a layout
that conforms to the interface guidelines for that platform.
Invariably, different platforms have different layouts for their
dialogs. QDialogButtonBox allows a developer to add buttons to it
and will automatically use the appropriate layout for the user's
desktop environment.</p>
<p>Most buttons for a dialog follow certain roles. Such roles
include:</p>
<ul>
<li>Accepting or rejecting the dialog.</li>
<li>Asking for help.</li>
<li>Performing actions on the dialog itself (such as resetting
fields or applying changes).</li>
</ul>
<p>There can also be alternate ways of dismissing the dialog which
may cause destructive results.</p>
<p>Most dialogs have buttons that can almost be considered standard
(e.g. <b>OK</b> and <b>Cancel</b> buttons). It is sometimes
convenient to create these buttons in a standard way.</p>
<p>There are a couple ways of using QDialogButtonBox. One ways is
to create the buttons (or button texts) yourself and add them to
the button box, specifying their role.</p>
<pre class="cpp">
findButton <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qpushbutton.html">QPushButton</a></span>(tr(<span class="string">"&Find"</span>));
findButton<span class="operator">-</span><span class="operator">></span>setDefault(<span class="keyword">true</span>);
moreButton <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qpushbutton.html">QPushButton</a></span>(tr(<span class="string">"&More"</span>));
moreButton<span class="operator">-</span><span class="operator">></span>setCheckable(<span class="keyword">true</span>);
moreButton<span class="operator">-</span><span class="operator">></span>setAutoDefault(<span class="keyword">false</span>);
buttonBox <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QDialogButtonBox</span>(<span class="type"><a href="qt.html">Qt</a></span><span class="operator">.</span>Vertical);
buttonBox<span class="operator">-</span><span class="operator">></span>addButton(findButton<span class="operator">,</span> <span class="type">QDialogButtonBox</span><span class="operator">.</span>ActionRole);
buttonBox<span class="operator">-</span><span class="operator">></span>addButton(moreButton<span class="operator">,</span> <span class="type">QDialogButtonBox</span><span class="operator">.</span>ActionRole);
</pre>
<p>Alternatively, QDialogButtonBox provides several standard
buttons (e.g. OK, Cancel, Save) that you can use. They exist as
flags so you can OR them together in the constructor.</p>
<pre class="cpp">
buttonBox <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QDialogButtonBox</span>(<span class="type">QDialogButtonBox</span><span class="operator">.</span>Ok
<span class="operator">|</span> <span class="type">QDialogButtonBox</span><span class="operator">.</span>Cancel);
connect(buttonBox<span class="operator">,</span> SIGNAL(accepted())<span class="operator">,</span> <span class="keyword">this</span><span class="operator">,</span> SLOT(accept()));
connect(buttonBox<span class="operator">,</span> SIGNAL(rejected())<span class="operator">,</span> <span class="keyword">this</span><span class="operator">,</span> SLOT(reject()));
</pre>
<p>You can mix and match normal buttons and standard buttons.</p>
<p>Currently the buttons are laid out in the following way if the
button box is horizontal:</p>
<table class="generic">
<tr class="odd" valign="top">
<td><img alt="GnomeLayout Horizontal" src="images/buttonbox-gnomelayout-horizontal.png" /></td>
<td>Button box laid out in horizontal <a href="qdialogbuttonbox.html#ButtonLayout-enum">GnomeLayout</a></td>
</tr>
<tr class="even" valign="top">
<td><img alt="KdeLayout Horizontal" src="images/buttonbox-kdelayout-horizontal.png" /></td>
<td>Button box laid out in horizontal <a href="qdialogbuttonbox.html#ButtonLayout-enum">KdeLayout</a></td>
</tr>
<tr class="odd" valign="top">
<td><img alt="MacLayout Horizontal" src="images/buttonbox-maclayout-horizontal.png" /></td>
<td>Button box laid out in horizontal <a href="qdialogbuttonbox.html#ButtonLayout-enum">MacLayout</a></td>
</tr>
<tr class="even" valign="top">
<td><img alt="WinLayout Horizontal" src="images/buttonbox-winlayout-horizontal.png" /></td>
<td>Button box laid out in horizontal <a href="qdialogbuttonbox.html#ButtonLayout-enum">WinLayout</a></td>
</tr>
</table>
<p>The buttons are laid out the following way if the button box is
vertical:</p>
<table class="generic">
<tr class="odd" valign="top">
<td><a href="qdialogbuttonbox.html#ButtonLayout-enum">GnomeLayout</a></td>
<td><a href="qdialogbuttonbox.html#ButtonLayout-enum">KdeLayout</a></td>
<td><a href="qdialogbuttonbox.html#ButtonLayout-enum">MacLayout</a></td>
<td><a href="qdialogbuttonbox.html#ButtonLayout-enum">WinLayout</a></td>
</tr>
<tr class="even" valign="top">
<td><img alt="GnomeLayout Vertical" src="images/buttonbox-gnomelayout-vertical.png" /></td>
<td><img alt="KdeLayout Vertical" src="images/buttonbox-kdelayout-vertical.png" /></td>
<td><img alt="MacLayout Vertical" src="images/buttonbox-maclayout-vertical.png" /></td>
<td><img alt="WinLayout Vertical" src="images/buttonbox-winlayout-vertical.png" /></td>
</tr>
</table>
<p>Additionally, button boxes that contain only buttons with
<a href="qdialogbuttonbox.html#ButtonRole-enum">ActionRole</a> or
<a href="qdialogbuttonbox.html#ButtonRole-enum">HelpRole</a> can be
considered modeless and have an alternate look on Mac OS X:</p>
<table class="generic">
<tr class="odd" valign="top">
<td>modeless horizontal <a href="qdialogbuttonbox.html#ButtonLayout-enum">MacLayout</a></td>
<td><img alt="Screenshot of modeless horizontal MacLayout" src="images/buttonbox-mac-modeless-horizontal.png" /></td>
</tr>
</table>
<p>When a button is clicked in the button box, the <a href="qdialogbuttonbox.html#clicked">clicked</a>() signal is emitted for
the actual button is that is pressed. For convenience, if the
button has an <a href="qdialogbuttonbox.html#ButtonRole-enum">AcceptRole</a>, <a href="qdialogbuttonbox.html#ButtonRole-enum">RejectRole</a>, or <a href="qdialogbuttonbox.html#ButtonRole-enum">HelpRole</a>, the <a href="qdialogbuttonbox.html#accepted">accepted</a>(), <a href="qdialogbuttonbox.html#rejected">rejected</a>(), or <a href="qdialogbuttonbox.html#helpRequested">helpRequested</a>() signals
are emitted respectively.</p>
<p>If you want a specific button to be default you need to call
<a href="qpushbutton.html#default-prop">QPushButton.setDefault</a>() on it
yourself. However, if there is no default button set and to
preserve which button is the default button across platforms when
using the <a href="qpushbutton.html#autoDefault-prop">QPushButton.autoDefault</a>
property, the first push button with the accept role is made the
default button when the QDialogButtonBox is shown,</p>
