<hr><h2><a name="details"></a>Detailed Description</h2>
The QFontDialog class provides a dialog widget for selecting a text font.
<p>
This dialog can be used to let the user choose a font with attributes and so on.
Normally you may use the static convenience function <a href="#4a9cc8">getFont</a>().

<hr><h2>Member Function Documentation</h2>
<h3 class="fn">bool<a name="c9a592"></a>QFontDialog::eventFilter(<a href="qobject.html">QObject</a>*o, <a href="qevent.html">QEvent</a>*e) <code>[virtualprotected]</code></h3>
<p>Event filter to make up, down, pageup and pagedown work correctly
in the line edits.
<p>Reimplemented from <a href="qobject.html#bd20fe">QObject.</a>
<h3 class="fn"><a href="qlistbox.html">QListBox</a>*<a name="fca5a4"></a>QFontDialog::familyListBox()const <code>[protected]</code></h3>
<p>Returns a pointer to the "font family" list box. This is usable
mainly if you reimplement updateFontFamilies();.
<h3 class="fn">void<a name="35a205"></a>QFontDialog::fontHighlighted(const<a href="qfont.html">QFont</a>&) <code>[signal]</code></h3>
<p>This signal is emitted, when the user changed a setting in the dialog.
<h3 class="fn">void<a name="6a37ea"></a>QFontDialog::fontSelected(const<a href="qfont.html">QFont</a>&) <code>[signal]</code></h3>
<p>This signal is emitted, when the user has chosen a font and clicked ok.
<h3 class="fn"><a href="qfont.html">QFont</a><a name="4a9cc8"></a>QFontDialog::getFont(bool*ok, <a href="qwidget.html">QWidget</a>*parent=0,constchar*name=0) <code>[static]</code></h3>
<p>Opens a modal font dialog and returns the font selected by the user.
<p>The <em>ok</em> parameter is set to TRUE if the user clicked OK, and FALSE if
the user clicked Cancel.
<p>If the user clicks Cancel the Qt default font is returned.
<p>This static function is less capable than the full QFontDialog object,
but is convenient and easy to use.
<p>Example:
<pre> // start at the current working directory and with *.cpp as filter
bool ok;
<a href="qfont.html">QFont</a> f = QFontDialog::getFont( &ok, this );
if ( ok ) {
// the user selected a valid font
} else {
// the user cancelled the dialog
}
</pre>
<h3 class="fn"><a href="qfont.html">QFont</a><a name="5eb535"></a>QFontDialog::getFont(bool*ok, const<a href="qfont.html">QFont</a>&initial, <a href="qwidget.html">QWidget</a>*parent=0, constchar*name=0) <code>[static]</code></h3>
<p>Opens a modal font dialog and returns the font selected by the user.
<p><em>initial</em> is the initial selected font.
<p>The <em>ok</em> parameter is set to TRUE if the user clicked OK, and FALSE if
the user clicked Cancel.
<p>If the user clicks Cancel the <em>initial</em> font is returned.
<p>This static function is less capable than the full QFontDialog object,
but is convenient and easy to use.
<p>Example:
<pre> // start at the current working directory and with *.cpp as filter
bool ok;
<a href="qfont.html">QFont</a> f = QFontDialog::getFont( &ok, QFont( "Times", 12 ), this );
if ( ok ) {
// the user selected a valid font
} else {
// the user cancelled the dialog
}
</pre>
<p>Another example:
<pre> mywidget.setFont( <a href="#4a9cc8">QFontDialog::getFont</a>( 0, mywidget.font() ) );
</pre>
<h3 class="fn"><a href="qcombobox.html">QComboBox</a>*<a name="d00b1b"></a>QFontDialog::scriptCombo()const <code>[protected]</code></h3>
<p>Returns a pointer to the "font style" list box. This is usable
mainly if you reimplement updateFontStyles();.
<h3 class="fn">void<a name="8fa2fd"></a>QFontDialog::sizeChanged(const<a href="qstring.html">QString</a>&s) <code>[protectedslot]</code></h3>
<p>This slot is called if the user changes the font size.
<h3 class="fn"><a href="qlistbox.html">QListBox</a>*<a name="9949b3"></a>QFontDialog::sizeListBox()const <code>[protected]</code></h3>
<p>Returns a pointer to the "font size" list box. This is usable
mainly if you reimplement updateFontSizes();.
<h3 class="fn"><a href="qlistbox.html">QListBox</a>*<a name="afa785"></a>QFontDialog::styleListBox()const <code>[protected]</code></h3>
<p>Returns a pointer to the "font style" list box. This is usable
mainly if you reimplement updateFontStyles();.
<h3 class="fn">void<a name="860aab"></a>QFontDialog::updateFamilies() <code>[virtualprotected]</code></h3>
<p>Update the contents of the "font family" list box. This
function can be reimplemented if you have special requirements.
<h3 class="fn">void<a name="fc4f47"></a>QFontDialog::updateScripts() <code>[virtualprotected]</code></h3>
<p>Update the contents of the "font script" combo box. This
function can be reimplemented if you have special requirements.
<h3 class="fn">void<a name="3d5051"></a>QFontDialog::updateSizes() <code>[virtualprotected]</code></h3>
<p>Update the contents of the "font size" list box. This
function can be reimplemented if you have special requirements.
<h3 class="fn">void<a name="2fea07"></a>QFontDialog::updateStyles() <code>[virtualprotected]</code></h3>
