font.</p>
<p>A font dialog is created through one of the static <a href="qfontdialog.html#getFont">getFont</a>() functions.</p>
<p>Examples:</p>
<pre class="cpp">
<span class="type">bool</span> ok;
<span class="type"><a href="qfont.html">QFont</a></span> font <span class="operator">=</span> <span class="type">QFontDialog</span><span class="operator">.</span><a href="qfontdialog.html#getFont">getFont</a>(
<span class="operator">&</span>ok<span class="operator">,</span> <span class="type"><a href="qfont.html">QFont</a></span>(<span class="string">"Helvetica [Cronyx]"</span><span class="operator">,</span> <span class="number">10</span>)<span class="operator">,</span> <span class="keyword">this</span>);
<span class="keyword">if</span> (ok) {
<span class="comment">// the user clicked OK and font is set to the font the user selected</span>
} <span class="keyword">else</span> {
<span class="comment">// the user canceled the dialog; font is set to the initial</span>
<span class="comment">// value, in this case Helvetica [Cronyx], 10</span>
}
</pre>
<p>The dialog can also be used to set a widget's font directly:</p>
<pre class="cpp">
myWidget<span class="operator">.</span><a href="qwidget.html#font-prop">setFont</a>(<span class="type">QFontDialog</span><span class="operator">.</span>getFont(<span class="number">0</span><span class="operator">,</span> myWidget<span class="operator">.</span>font()));
</pre>
<p>If the user clicks OK the font they chose will be used for
myWidget, and if they click Cancel the original font is used.</p>

<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="FontDialogOption-enum" />QFontDialog.FontDialogOption</h3><p>This enum specifies various options that affect the look and
feel of a font dialog.</p>
<table class="valuelist">
<tr class="odd" valign="top">
<th class="tblConst">Constant</th>
<th class="tblval">Value</th>
<th class="tbldscr">Description</th>

<td class="topAlign"><tt>0x00000002</tt></td>
<td class="topAlign">Use Qt's standard font dialog on the Mac

is never used, but this is likely to change in future Qt
releases.)</td>
</tr>
</table>
<p>This enum was introduced or modified in Qt 4.5.</p>
<p>The FontDialogOptions type is a typedef for <a href="qflags.html">QFlags</a><FontDialogOption>. It stores an OR
combination of FontDialogOption values.</p>
<p><b>See also</b> <a href="qfontdialog.html#options-prop">options</a>, <a href="qfontdialog.html#setOption">setOption</a>(), and <a href="qfontdialog.html#testOption">testOption</a>().</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QFontDialog" />QFontDialog.__init__ (<i>self</i>, <a href="qwidget.html">QWidget</a> <i>parent</i> = None)</h3><p>The <i>parent</i> argument, if not None, causes <i>self</i> to be owned by Qt instead of PyQt.</p><p>Constructs a standard font dialog.</p>
<p>Use <a href="qfontdialog.html#currentFont-prop">setCurrentFont</a>() to set the
initial font attributes.</p>
<p>The <i>parent</i> parameter is passed to the <a href="qdialog.html">QDialog</a> constructor.</p>
<p>This function was introduced in Qt 4.5.</p>
<p><b>See also</b> <a href="qfontdialog.html#getFont">getFont</a>().</p>
<h3 class="fn"><a name="QFontDialog-2" />QFontDialog.__init__ (<i>self</i>, <a href="qfont.html">QFont</a> <i>initial</i>, <a href="qwidget.html">QWidget</a> <i>parent</i> = None)</h3><p>The <i>parent</i> argument, if not None, causes <i>self</i> to be owned by Qt instead of PyQt.</p><p>Constructs a standard font dialog with the given <i>parent</i>
and specified <i>initial</i> font.</p>
<p>This function was introduced in Qt 4.5.</p>
<h3 class="fn"><a name="changeEvent" />QFontDialog.changeEvent (<i>self</i>, <a href="qevent.html">QEvent</a> <i>e</i>)</h3><p>Reimplemented from <a href="qwidget.html#changeEvent">QWidget.changeEvent</a>().</p>
<h3 class="fn"><a name="currentFont" /><a href="qfont.html">QFont</a> QFontDialog.currentFont (<i>self</i>)</h3><h3 class="fn"><a name="done" />QFontDialog.done (<i>self</i>, int <i>result</i>)</h3><p>Reimplemented from <a href="qdialog.html#done">QDialog.done</a>().</p>
<p>Closes the dialog and sets its result code to <i>result</i>. If
this dialog is shown with <a href="qdialog.html#exec">exec_</a>(),
done() causes the local event loop to finish, and <a href="qdialog.html#exec">exec_</a>() to return <i>result</i>.</p>
<p><b>See also</b> <a href="qdialog.html#done">QDialog.done</a>().</p>
<h3 class="fn"><a name="getFont" />(<a href="qfont.html">QFont</a>, bool <i>ok</i>) QFontDialog.getFont (<a href="qfont.html">QFont</a> <i>initial</i>, <a href="qwidget.html">QWidget</a> <i>parent</i>, QString <i>title</i>, <a href="qfontdialog-fontdialogoptions.html">FontDialogOptions</a> <i>options</i>)</h3><p>Executes a modal font dialog and returns a font.</p>
<p>If the user clicks <b>OK</b>, the selected font is returned. If
the user clicks <b>Cancel</b>, the <i>initial</i> font is
returned.</p>
<p>The dialog is constructed with the given <i>parent</i> and the
options specified in <i>options</i>. <i>title</i> is shown as the
window title of the dialog and <i>initial</i> is the initially
selected font. If the <i>ok</i> parameter is not-null, the value it
refers to is set to true if the user clicks <b>OK</b>, and set to
false if the user clicks <b>Cancel</b>.</p>
<p>Examples:</p>
<pre class="cpp">
<span class="type">bool</span> ok;
<span class="type"><a href="qfont.html">QFont</a></span> font <span class="operator">=</span> <span class="type"><a href="qfontdialog.html">QFontDialog</a></span><span class="operator">.</span>getFont(<span class="operator">&</span>ok<span class="operator">,</span> <span class="type"><a href="qfont.html">QFont</a></span>(<span class="string">"Times"</span><span class="operator">,</span> <span class="number">12</span>)<span class="operator">,</span> <span class="keyword">this</span>);
<span class="keyword">if</span> (ok) {
<span class="comment">// font is set to the font the user selected</span>
} <span class="keyword">else</span> {
<span class="comment">// the user canceled the dialog; font is set to the initial</span>
<span class="comment">// value, in this case Times, 12.</span>
}
</pre>
<p>The dialog can also be used to set a widget's font directly:</p>
<pre class="cpp">
myWidget<span class="operator">.</span><a href="qwidget.html#font-prop">setFont</a>(<span class="type"><a href="qfontdialog.html">QFontDialog</a></span><span class="operator">.</span>getFont(<span class="number">0</span><span class="operator">,</span> myWidget<span class="operator">.</span>font()));
</pre>
<p>In this example, if the user clicks OK the font they chose will
be used, and if they click Cancel the original font is used.</p>
