<!-- $$$QStyle-description -->
<div class="descr">
<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 eight different styles.</p>
<p class="centerAlign"><img src="images/qstyle-comboboxes.png" alt="Eight combo boxes" /></p><p>Topics:</p>
<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 class="cpp"> <span class="operator">.</span><span class="operator">/</span>myapplication <span class="operator">-</span>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 class="cpp"> <span class="type">void</span> MyWidget<span class="operator">::</span>paintEvent(<span class="type"><a href="qpaintevent.html">QPaintEvent</a></span> <span class="operator">*</span> <span class="comment">/* event */</span>)
{
<span class="type"><a href="qpainter.html">QPainter</a></span> painter(<span class="keyword">this</span>);
<span class="type"><a href="qstyleoptionfocusrect.html">QStyleOptionFocusRect</a></span> option;

<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 class="cpp"> <span class="type"><a href="qstylepainter.html">QStylePainter</a></span> painter(<span class="keyword">this</span>);

<h3>Creating a Custom Style</h3>
<p>You can create a custom look and feel for your application by creating a custom style. There are two approaches to creating a custom style. In the static approach, you either choose an existing QStyle class, subclass it, and reimplement virtual functions to provide the custom behavior, or you create an entire QStyle class from scratch. In the dynamic approach, you modify the behavior of your system style at runtime. The static approach is described below. The dynamic approach is described in <a href="qproxystyle.html">QProxyStyle</a>.</p>
<p>The first step in the static approach is to pick one of the styles provided by Qt from which you will build your custom style. Your choice of QStyle class will depend on which style resembles your desired style the most. The most general class that you can use as a base is <a href="qcommonstyle.html">QCommonStyle</a> (not QStyle). This is because Qt requires its styles to be <a href="qcommonstyle.html">QCommonStyle</a>s.</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="cpp"> <span class="keyword">class</span> CustomStyle : <span class="keyword">public</span> <span class="type"><a href="qwindowsstyle.html">QWindowsStyle</a></span>
{
Q_OBJECT
<span class="keyword">public</span>:
CustomStyle()
<span class="operator">~</span>CustomStyle() {}
<span class="type">void</span> drawPrimitive(PrimitiveElement element<span class="operator">,</span> <span class="keyword">const</span> <span class="type"><a href="qstyleoption.html">QStyleOption</a></span> <span class="operator">*</span>option<span class="operator">,</span>

};</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>
<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 class="cpp"> <span class="type"><a href="qspinbox.html">QSpinBox</a></span> <span class="operator">*</span>spinBox <span class="operator">=</span> qobject_cast<span class="operator"><</span><span class="type"><a href="qspinbox.html">QSpinBox</a></span> <span class="operator">*</span><span class="operator">></span>(widget);
<span class="keyword">if</span> (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_IndicatorSpinDown</a>.</p>
<p>The documentation for the <a href="widgets-styles.html">Styles</a> example covers this topic in more detail.</p>
<p><b>Warning:</b> Qt style sheets are currently not supported for custom QStyle subclasses. We plan to address this in some future release.</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 to pass the custom style to the <a href="qapplication.html#setStyle">QApplication::setStyle</a>() static function before creating the <a href="qapplication.html">QApplication</a> object:</p>
<pre class="cpp"> <span class="preprocessor">#include <QtGui></span>
<span class="preprocessor">#include "customstyle.h"</span>
<span class="type">int</span> main(<span class="type">int</span> argc<span class="operator">,</span> <span class="type">char</span> <span class="operator">*</span>argv<span class="operator">[</span><span class="operator">]</span>)
{
<span class="type"><a href="qapplication.html">QApplication</a></span><span class="operator">::</span>setStyle(<span class="keyword">new</span> CustomStyle);
<span class="type"><a href="qapplication.html">QApplication</a></span> app(argc<span class="operator">,</span> argv);
<span class="type"><a href="qspinbox.html">QSpinBox</a></span> spinBox;
spinBox<span class="operator">.</span>show();
<span class="keyword">return</span> app<span class="operator">.</span>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 custom style available for use in other applications, which may not be yours and hence 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 class="cpp"> <span class="operator">.</span><span class="operator">/</span>myapplication <span class="operator">-</span>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>
<a name="styles-in-item-views"></a>
<h3>Styles in Item Views</h3>
<p>The painting of items in views is performed by a delegate. Qt's default delegate, <a href="qstyleditemdelegate.html">QStyledItemDelegate</a>, is also used for for calculating bounding rectangles of items, and their sub-elements for the various kind of item <a href="qt.html#ItemDataRole-enum">data roles</a> <a href="qstyleditemdelegate.html">QStyledItemDelegate</a> supports. See the <a href="qstyleditemdelegate.html">QStyledItemDelegate</a> class description to find out which datatypes and roles are supported. You can read more about item data roles in <a href="model-view-programming.html">Model/View Programming</a>.</p>
<p>When <a href="qstyleditemdelegate.html">QStyledItemDelegate</a> paints its items, it draws <a href="qstyle.html#ControlElement-enum">CE_ItemViewItem</a>, and calculates their size with <a href="qstyle.html#ContentsType-enum">CT_ItemViewItem</a>. Note also that it uses <a href="qstyle.html#SubElement-enum">SE_ItemViewItemText</a> to set the size of editors. When implementing a style to customize drawing of item views, you need to check the implementation of <a href="qcommonstyle.html">QCommonStyle</a> (and any other subclasses from which your style inherits). This way, you find out which and how other style elements are painted, and you can then reimplement the painting of elements that should be drawn differently.</p>
<p>We include a small example where we customize the drawing of item backgrounds.</p>
<pre class="cpp"> <span class="keyword">switch</span> (element) {
<span class="keyword">case</span> (PE_PanelItemViewItem): {
painter<span class="operator">-</span><span class="operator">></span>save();

painter<span class="operator">-</span><span class="operator">></span>fillRect(option<span class="operator">-</span><span class="operator">></span>rect<span class="operator">,</span> <span class="type"><a href="qbrush.html">QBrush</a></span>(backgroundGradient));
painter<span class="operator">-</span><span class="operator">></span>restore();
<span class="keyword">break</span>;
}
<span class="keyword">default</span>:
<span class="type"><a href="qwindowsstyle.html">QWindowsStyle</a></span><span class="operator">::</span>drawPrimitive(element<span class="operator">,</span> option<span class="operator">,</span> painter<span class="operator">,</span> widget);
}</pre>
<p>The primitive element <a href="qstyle.html#PrimitiveElement-enum">PE_PanelItemViewItem</a> is responsible for painting the background of items, and is called from <a href="qcommonstyle.html">QCommonStyle</a>'s implementation of <a href="qstyle.html#ControlElement-enum">CE_ItemViewItem</a>.</p>
<p>To add support for drawing of new datatypes and item data roles, it is necessary to create a custom delegate. But if you only need to support the datatypes implemented by the default delegate, a custom style does not need an accompanying delegate. The <a href="qstyleditemdelegate.html">QStyledItemDelegate</a> class description gives more information on custom delegates.</p>
<p>The drawing of item view headers is also done by the style, giving control over size of header items and row and column sizes.</p>

<p>Initializes the appearance of the given <i>widget</i>.</p>
<p>This function is called for every widget at some point after it has been fully created but just <i>before</i> it is shown for the very first time.</p>
<p>Note that the default implementation does nothing. Reasonable actions in this function might be to call the <a href="qwidget-qt3.html#setBackgroundMode" class="compat">QWidget::setBackgroundMode</a>() function for the widget. Do not use the function to set, for example, the geometry. Reimplementing this function provides a back-door through which the appearance of a widget can be changed, but with Qt's style engine it is rarely necessary to implement this function; reimplement <a href="qstyle.html#drawItemPixmap">drawItemPixmap</a>(), <a href="qstyle.html#drawItemText">drawItemText</a>(), <a href="qstyle.html#drawPrimitive">drawPrimitive</a>(), etc. instead.</p>
<p>The <a href="qobject.html#inherits">QWidget::inherits</a>() function may provide enough information to allow class-specific customizations. But because new <a href="qstyle.html">QStyle</a> subclasses are expected to work reasonably with all current and <i>future</i> widgets, limited use of hard-coded customization is recommended.</p>
