<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qfontdialog.html">QFontDialog</a> class provides a dialog widget for selecting a 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">
bool ok;
<span class="type"><a href="../qtgui/qfont.html">QFont</a></span> font <span class="operator">=</span> <span class="type"><a href="qfontdialog.html#QFontDialog">QFontDialog</a></span><span class="operator">::</span>getFont(
<span class="operator">&</span>ok<span class="operator">,</span> <span class="type"><a href="../qtgui/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>setFont(<span class="type"><a href="qfontdialog.html#QFontDialog">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>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>

<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>

<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>setFont(<span class="type"><a href="qfontdialog.html#QFontDialog">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>
<p><b>Warning:</b> Do not delete <i>parent</i> during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the <a href="qfontdialog.html">QFontDialog</a> constructors.</p>

<p>This is an overloaded function.</p>
<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 Qt default font is returned.</p>
<p>The dialog is constructed with the given <i>parent</i>. 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 false if the user clicks <b>Cancel</b>.</p>
<p>Example:</p>
<pre class="cpp">
bool ok;
<span class="type"><a href="../qtgui/qfont.html">QFont</a></span> font <span class="operator">=</span> <span class="type"><a href="qfontdialog.html#QFontDialog">QFontDialog</a></span><span class="operator">::</span>getFont(<span class="operator">&</span>ok<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 default</span>
<span class="comment">// application font, QApplication::font()</span>
}
</pre>
<p><b>Warning:</b> Do not delete <i>parent</i> during the execution of the dialog. If you want to do this, you should create the dialog yourself using one of the <a href="qfontdialog.html">QFontDialog</a> constructors.</p>
