<hr><a name="details"></a><h2>Detailed Description</h2>
The QStyle class specifies the look and feel of a GUI.
<p> A large number of GUI elements are common to many widgets. The
QStyle class allows the look of these elements to be modified
across all widgets that use the QStyle functions. It also
provides two feel options: <a href="motif-extension.html#Motif">Motif</a> and Windows.
<p> Although it is not possible to fully enumerate the look of
graphical elements and the feel of widgets in a GUI, QStyle
provides a considerable amount of control and customisability.
<p> In Qt 1.x the look and feel option for widgets was specified by a
single value: the GUIStyle. Starting with Qt 2.0, this notion was
expanded to allow the look to be specified by virtual drawing
functions.
<p> Derived classes may reimplement some or all of the drawing
functions to modify the look of all widgets that use those
functions.
<p> Languages written from right to left (such as Arabic and Hebrew)
usually also mirror the whole layout of widgets. If you design a
style, you should take special care when drawing asymmetric
elements to make sure that they also look correct in a mirrored
layout. You can start your application with <tt>-reverse</tt> to check
the mirrored layout. Also notice, that for a reversed layout, the
light usually comes from top right instead of top left.
<p> The actual reverse layout is performed automatically when
possible. However, for the sake of flexibility, the translation
cannot be performed everywhere. The documentation for each
function in the QStyle API states whether the function
expects/returns logical or screen coordinates. Using logical
coordinates (in ComplexControls, for example) provides great
flexibility in controlling the look of a widget. Use <a href="#visualRect">visualRect</a>()
when necessary to translate logical coordinates into screen
coordinates for drawing.
<p> In Qt versions prior to 3.0, if you wanted a low level route into
changing the appearance of a widget, you would reimplement
<a href="#polish">polish</a>(). With the new 3.0 style engine the recommended approach
is to reimplement the draw functions, for example <a href="#drawItem">drawItem</a>(),
<a href="#drawPrimitive">drawPrimitive</a>(), <a href="#drawControl">drawControl</a>(), <a href="#drawControlMask">drawControlMask</a>(),
<a href="#drawComplexControl">drawComplexControl</a>() and <a href="#drawComplexControlMask">drawComplexControlMask</a>(). Each of these
functions is called with a range of parameters that provide
information that you can use to determine how to draw them, e.g.
style flags, rectangle, color group, etc.
<p> For information on changing elements of an existing style or
creating your own style see the <a href="customstyles.html">Style
overview</a>.
<p> Styles can also be created as <a href="plugins-howto.html">plugins</a>.

<p> Draws the ComplexControl <em>control</em> using the painter <em>p</em> in the
area <em>r</em>. Colors are used from the color group <em>cg</em>. The <em>sub</em>
argument specifies which SubControls to draw. Multiple SubControls
can be OR'ed together. The <em>subActive</em> argument specifies which
SubControl is active.
<p> The rect <em>r</em> should be in logical coordinates. Reimplementations
of this function should use <a href="#visualRect">visualRect</a>() to change the logical
coordinates into screen coordinates when using <a href="#drawPrimitive">drawPrimitive</a>() and
<a href="#drawControl">drawControl</a>().
<p> The <em>how</em> argument is used to control how the ComplexControl is
drawn. Multiple flags can OR'ed together. See the table below for
an explanation of which flags are used with the various
ComplexControls.
<p> The <em>widget</em> argument is a pointer to a <a href="qwidget.html">QWidget</a> or one of its
subclasses. The widget can be cast to the appropriate type based
on the value of <em>control</em>. The <em>opt</em> argument can be used to
pass extra information required when drawing the ComplexControl.
Note that <em>opt</em> may be the default value even for ComplexControls
that can make use of the extra options. See the table below for
the appropriate <em>widget</em> and <em>opt</em> usage:

<h3 class=fn>void <a name="polish"></a>QStyle::polish ( <a href="qwidget.html">QWidget</a> * )<tt> [virtual]</tt>
</h3>
Initializes the appearance of a widget.
<p> This function is called for every widget at some point after it
has been fully created but just <em>before</em> it is shown the very
first time.
<p> Reasonable actions in this function might be to call
<a href="qwidget.html#setBackgroundMode">QWidget::setBackgroundMode</a>() for the widget. An example of highly
unreasonable use would be setting the geometry! Reimplementing
this function gives you a back-door through which you can change
the appearance of a widget. With Qt 3.0's style engine you will
rarely need to write your own <a href="#polish">polish</a>(); instead reimplement
<a href="#drawItem">drawItem</a>(), <a href="#drawPrimitive">drawPrimitive</a>(), etc.
<p> The <a href="qobject.html#inherits">QWidget::inherits</a>() function may provide enough information to
allow class-specific customizations. But be careful not to
hard-code things too much because new QStyle subclasses are
expected to work reasonably with all current and <em>future</em>
widgets.
<p> <p>See also <a href="#unPolish">unPolish</a>().
<h3 class=fn>void <a name="polish-2"></a>QStyle::polish ( <a href="qapplication.html">QApplication</a> * )<tt> [virtual]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> Late initialization of the <a href="qapplication.html">QApplication</a> object.
<p> <p>See also <a href="#unPolish">unPolish</a>().
<h3 class=fn>void <a name="polish-3"></a>QStyle::polish ( <a href="qpalette.html">QPalette</a> & )<tt> [virtual]</tt>
</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> The style may have certain requirements for color palettes. In
this function it has the chance to change the palette according to
these requirements.
<p> <p>See also <a href="qpalette.html">QPalette</a> and <a href="qapplication.html#setPalette">QApplication::setPalette</a>().
<h3 class=fn>void <a name="polishPopupMenu"></a>QStyle::polishPopupMenu ( <a href="qpopupmenu.html">QPopupMenu</a> * )<tt> [pure virtual]</tt>
</h3>
Polishes the popup menu according to the GUI style. This usually
means setting the mouse tracking
(<a href="qwidget.html#setMouseTracking">QPopupMenu::setMouseTracking</a>()) and whether the menu is
checkable by default (<a href="qpopupmenu.html#setCheckable">QPopupMenu::setCheckable</a>()).

</h3>
<p> Returns the SubControl for <em>widget</em> at the point <em>pos</em>. The <em>widget</em> argument is a pointer to a <a href="qwidget.html">QWidget</a> or one of its
subclasses. The widget can be cast to the appropriate type based
on the value of <em>control</em>. The <em>opt</em> argument can be used to
pass extra information required when drawing the ComplexControl.
Note that <em>opt</em> may be the default value even for ComplexControls
that can make use of the extra options. See <a href="#drawComplexControl">drawComplexControl</a>()
for an explanation of the <em>widget</em> and <em>opt</em> arguments.
<p> Note that <em>pos</em> is passed in screen coordinates. When using
<a href="#querySubControlMetrics">querySubControlMetrics</a>() to check for hits and misses, use
<a href="#visualRect">visualRect</a>() to change the logical coordinates into screen
coordinates.
<p> <p>See also <a href="#drawComplexControl">drawComplexControl</a>(), <a href="#ComplexControl-enum">ComplexControl</a>, <a href="#SubControl-enum">SubControl</a>, and <a href="#querySubControlMetrics">querySubControlMetrics</a>().

</h3>
<p> Returns the rect for the SubControl <em>subcontrol</em> for <em>widget</em> in
logical coordinates.
<p> The <em>widget</em> argument is a pointer to a <a href="qwidget.html">QWidget</a> or one of its
subclasses. The widget can be cast to the appropriate type based
on the value of <em>control</em>. The <em>opt</em> argument can be used to
pass extra information required when drawing the ComplexControl.
Note that <em>opt</em> may be the default value even for ComplexControls
that can make use of the extra options. See <a href="#drawComplexControl">drawComplexControl</a>()
for an explanation of the <em>widget</em> and <em>opt</em> arguments.

<p> Returns the size of <em>widget</em> based on the contents size <em>contentsSize</em>.
<p> The <em>widget</em> argument is a pointer to a <a href="qwidget.html">QWidget</a> or one of its
