<h2>Detailed Description</h2>
<p>The QStyle class is an abstract base class that encapsulates the look and feel of a GUI.</p>
<p>Qt contains a set of QStyle subclasses that emulate the styles of the different platforms supported by Qt (<a href="qwindowsstyle.html">QWindowsStyle</a>, <a href="qmacstyle.html">QMacStyle</a>, <a href="qmotifstyle.html">QMotifStyle</a>, etc.). By default, these styles are built into the <a href="qtgui.html">QtGui</a> library. Styles can also be made available as plugins.</p>
<p>Qt's built-in widgets use QStyle to perform nearly all of their drawing, ensuring that they look exactly like the equivalent native widgets. The diagram below shows a <a href="qcombobox.html">QComboBox</a> in six different styles.</p>
<p align="center"><img src="images/qstyle-comboboxes.png" alt="Six combo boxes" /></p><p>Topics:</p>

<li><a href="#right-to-left-desktops">Right-to-Left Desktops</a></li>
</ul>
<a name="setting-a-style"></a>
<h3>Setting a Style</h3>
<p>The style of the entire application can be set using the <a href="qapplication.html#setStyle">QApplication::setStyle</a>() function. It can also be specified by the user of the application, using the <tt>-style</tt> command-line option:</p>
<pre> ./myapplication -style motif</pre>
<p>If no style is specified, Qt will choose the most appropriate style for the user's platform or desktop environment.</p>
<p>A style can also be set on an individual widget using the <a href="qwidget.html#setStyle">QWidget::setStyle</a>() function.</p>
<a name="developing-style-aware-custom-widgets"></a>
<h3>Developing Style-Aware Custom Widgets</h3>
<p>If you are developing custom widgets and want them to look good on all platforms, you can use QStyle functions to perform parts of the widget drawing, such as <a href="qstyle.html#drawItemText">drawItemText</a>(), <a href="qstyle.html#drawItemPixmap">drawItemPixmap</a>(), <a href="qstyle.html#drawPrimitive">drawPrimitive</a>(), <a href="qstyle.html#drawControl">drawControl</a>(), and <a href="qstyle.html#drawComplexControl">drawComplexControl</a>().</p>
<p>Most QStyle draw functions take four arguments:</p>
<ul>
<li>an enum value specifying which graphical element to draw</li>
<li>a <a href="qstyleoption.html">QStyleOption</a> specifying how and where to render that element</li>
<li>a <a href="qpainter.html">QPainter</a> that should be used to draw the element</li>
<li>a <a href="qwidget.html">QWidget</a> on which the drawing is performed (optional)</li>
</ul>
<p>For example, if you want to draw a focus rectangle on your widget, you can write:</p>
<pre> void MyWidget::paintEvent(QPaintEvent * /* event */)
{
QPainter painter(this);
QStyleOptionFocusRect option;
option.initFrom(this);
option.backgroundColor = palette().color(QPalette::Background);
style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);
}</pre>
<p>QStyle gets all the information it needs to render the graphical element from <a href="qstyleoption.html">QStyleOption</a>. The widget is passed as the last argument in case the style needs it to perform special effects (such as animated default buttons on Mac OS X), but it isn't mandatory. In fact, you can use QStyle to draw on any paint device, not just widgets, by setting the <a href="qpainter.html">QPainter</a> properly.</p>
<p><a href="qstyleoption.html">QStyleOption</a> has various subclasses for the various types of graphical elements that can be drawn. For example, <a href="qstyle.html#PrimitiveElement-enum">PE_FrameFocusRect</a> expects a <a href="qstyleoptionfocusrect.html">QStyleOptionFocusRect</a> argument.</p>
<p>To ensure that drawing operations are as fast as possible, <a href="qstyleoption.html">QStyleOption</a> and its subclasses have public data members. See the <a href="qstyleoption.html">QStyleOption</a> class documentation for details on how to use it.</p>
<p>For convenience, Qt provides the <a href="qstylepainter.html">QStylePainter</a> class, which combines a QStyle, a <a href="qpainter.html">QPainter</a>, and a <a href="qwidget.html">QWidget</a>. This makes it possible to write</p>
<pre> QStylePainter painter(this);
...
painter.drawPrimitive(QStyle::PE_FrameFocusRect, option);</pre>
<p>instead of</p>
<pre> QPainter painter(this);
...
style()->drawPrimitive(QStyle::PE_FrameFocusRect, &option, &painter, this);</pre>
<a name="creating-a-custom-style"></a>
<h3>Creating a Custom Style</h3>
<p>If you want to design a custom look and feel for your application, the first step is to pick one of the base styles provided with Qt to build your custom style from. The choice will depend on which existing style resembles your style the most.</p>
<p>Depending on which parts of the base style you want to change, you must reimplement the functions that are used to draw those parts of the interface. To illustrate this, we will modify the look of the spin box arrows drawn by <a href="qwindowsstyle.html">QWindowsStyle</a>. The arrows are <i>primitive elements</i> that are drawn by the <a href="qstyle.html#drawPrimitive">drawPrimitive</a>() function, so we need to reimplement that function. We need the following class declaration:</p>
<pre> class CustomStyle : public QWindowsStyle
{
Q_OBJECT
public:
CustomStyle()
~CustomStyle() {}
void drawPrimitive(PrimitiveElement element, const QStyleOption *option,
QPainter *painter, const QWidget *widget) const;
};</pre>
<p>To draw its up and down arrows, <a href="qspinbox.html">QSpinBox</a> uses the <a href="qstyle.html#PrimitiveElement-enum">PE_IndicatorSpinUp</a> and <a href="qstyle.html#PrimitiveElement-enum">PE_IndicatorSpinDown</a> primitive elements. Here's how to reimplement the <a href="qstyle.html#drawPrimitive">drawPrimitive</a>() function to draw them differently:</p>
<pre> void CustomStyle::drawPrimitive(PrimitiveElement element, const QStyleOption *option,
QPainter *painter, const QWidget *widget) const
{
if (element == PE_IndicatorSpinUp || element == PE_IndicatorSpinDown) {
QPolygon points(3);
int x = option->rect.x();
int y = option->rect.y();
int w = option->rect.width() / 2;
int h = option->rect.height() / 2;
x += (option->rect.width() - w) / 2;
y += (option->rect.height() - h) / 2;
if (element == PE_IndicatorSpinUp) {
points[0] = QPoint(x, y + h);
points[1] = QPoint(x + w, y + h);
points[2] = QPoint(x + w / 2, y);
} else { <span class="comment">// PE_SpinBoxDown</span>
points[0] = QPoint(x, y);
points[1] = QPoint(x + w, y);
points[2] = QPoint(x + w / 2, y + h);
}
if (option->state & State_Enabled) {
painter->setPen(option->palette.mid().color());
painter->setBrush(option->palette.buttonText());
} else {
painter->setPen(option->palette.buttonText().color());
painter->setBrush(option->palette.mid());
}
painter->drawPolygon(points);
} else {
QWindowsStyle::drawPrimitive(element, option, painter, widget);
}
}</pre>
<p>Notice that we don't use the <tt>widget</tt> argument, except to pass it on to the QWindowStyle::drawPrimitive() function. As mentioned earlier, the information about what is to be drawn and how it should be drawn is specified by a <a href="qstyleoption.html">QStyleOption</a> object, so there is no need to ask the widget.</p>
<p>If you need to use the <tt>widget</tt> argument to obtain additional information, be careful to ensure that it isn't 0 and that it is of the correct type before using it. For example:</p>
<pre> QSpinBox *spinBox = qobject_cast<QSpinBox *>(widget);
if (spinBox) {
...
}</pre>
<p>When implementing a custom style, you cannot assume that the widget is a <a href="qspinbox.html">QSpinBox</a> just because the enum value is called <a href="qstyle.html#PrimitiveElement-enum">PE_IndicatorSpinUp</a> or <a href="qstyle.html#PrimitiveElement-enum">PE_IndicatorSpinUp</a>.</p>
<p>The documentation for the <a href="widgets-styles.html">Styles</a> example covers this topic in more detail.</p>
<a name="using-a-custom-style"></a>
<h3>Using a Custom Style</h3>
<p>There are several ways of using a custom style in a Qt application. The simplest way is call the <a href="qapplication.html#setStyle">QApplication::setStyle</a>() static function before creating the <a href="qapplication.html">QApplication</a> object:</p>
<pre> #include <QtGui>
#include "customstyle.h"
int main(int argc, char *argv[])
{
QApplication::setStyle(new CustomStyle);
QApplication app(argc, argv);
QSpinBox spinBox;
spinBox.show();
return app.exec();
}</pre>
<p>You can call <a href="qapplication.html#setStyle">QApplication::setStyle</a>() at any time, but by calling it before the constructor, you ensure that the user's preference, set using the <tt>-style</tt> command-line option, is respected.</p>
<p>You may want to make your style available for use in other applications, some of which may not be yours and are not available for you to recompile. The Qt Plugin system makes it possible to create styles as plugins. Styles created as plugins are loaded as shared objects at runtime by Qt itself. Please refer to the <a href="plugins-howto.html">Qt Plugin</a> documentation for more information on how to go about creating a style plugin.</p>
<p>Compile your plugin and put it into Qt's <tt>plugins/styles</tt> directory. We now have a pluggable style that Qt can load automatically. To use your new style with existing applications, simply start the application with the following argument:</p>
<pre> ./myapplication -style custom</pre>
<p>The application will use the look and feel from the custom style you implemented.</p>
<a name="right-to-left-desktops"></a>
<h3>Right-to-Left Desktops</h3>
<p>Languages written from right to left (such as Arabic and Hebrew) usually also mirror the whole layout of widgets, and require the light to come from the screen's top-right corner instead of top-left.</p>
<p>If you create a custom style, you should take special care when drawing asymmetric elements to make sure that they also look correct in a mirrored layout. An easy way to test your styles is to run applications with the <tt>-reverse</tt> command-line option or to call <a href="qapplication.html#layoutDirection-prop">QApplication::setLayoutDirection</a>() in your <tt>main()</tt> function.</p>
<p>Here are some things to keep in mind when making a style work well in a right-to-left environment:</p>
<ul>
<li><a href="qstyle.html#subControlRect">subControlRect</a>() and <a href="qstyle.html#subElementRect">subElementRect</a>() return rectangles in screen coordinates</li>
<li><a href="qstyleoption.html#direction-var">QStyleOption::direction</a> indicates in which direction the item should be drawn in</li>
<li>If a style is not right-to-left aware it will display items as if it were left-to-right</li>
<li><a href="qstyle.html#visualRect">visualRect</a>(), <a href="qstyle.html#visualPos">visualPos</a>(), and <a href="qstyle.html#visualAlignment">visualAlignment</a>() are helpful functions that will translate from logical to screen representations.</li>
<li><a href="qstyle.html#alignedRect">alignedRect</a>() will return a logical rect aligned for the current direction</li>
</ul>

<p>This function was introduced in Qt 4.1.</p>
<p>See also <a href="qstyle.html#standardIconImplementation">standardIconImplementation</a>() and <a href="qstyle.html#standardPixmap">standardPixmap</a>().</p>
<h3 class="fn"><a name="standardIconImplementation"></a><a href="qicon.html">QIcon</a> QStyle::standardIconImplementation ( <a href="qstyle.html#StandardPixmap-enum">StandardPixmap</a> <i>standardIcon</i>, const <a href="qstyleoption.html">QStyleOption</a> * <i>option</i> = 0, const <a href="qwidget.html">QWidget</a> * <i>widget</i> = 0 ) const <tt> [protected slot]</tt></h3>
<p>Returns an icon for the given <i>standardIcon</i>.</p>
<p>Reimplement this slot to provide your own icons in a <a href="qstyle.html">QStyle</a> subclass; because of binary compatibility constraints, the <a href="qstyle.html#standardIcon">standardIcon</a>() function (introduced in Qt 4.1) is not virtual. Instead, <a href="qstyle.html#standardIcon">standardIcon</a>() will dynamically detect and call <i>this</i> slot. The default implementation simply calls the <a href="qstyle.html#standardPixmap">standardPixmap</a>() function with the given parameters.</p>
<p>The <i>standardIcon</i> is a standard pixmap which can follow some existing GUI style or guideline. The <i>option</i> argument can be used to pass extra information required when defining the appropiate icon. The <i>widget</i> argument is optional and can also be used to aid the determination of the icon.</p>
