other paint devices.</p>
<p>QPainter provides highly optimized functions to do most of the
drawing GUI programs require. It can draw everything from simple
lines to complex shapes like pies and chords. It can also draw
aligned text and pixmaps. Normally, it draws in a "natural"
coordinate system, but it can also do view and world
transformation. QPainter can operate on any object that inherits
the <a href="qpaintdevice.html">QPaintDevice</a> class.</p>
<p>The common use of QPainter is inside a widget's paint event:
Construct and customize (e.g. set the pen or the brush) the
painter. Then draw. Remember to destroy the QPainter object after
drawing. For example:</p>
<pre class="cpp">
<span class="type">void</span> SimpleExampleWidget<span class="operator">.</span>paintEvent(<span class="type"><a href="qpaintevent.html">QPaintEvent</a></span> <span class="operator">*</span>)
{
<span class="type">QPainter</span> painter(<span class="keyword">this</span>);
painter<span class="operator">.</span>setPen(<span class="type"><a href="qt.html">Qt</a></span><span class="operator">.</span>blue);
painter<span class="operator">.</span>setFont(<span class="type"><a href="qfont.html">QFont</a></span>(<span class="string">"Arial"</span><span class="operator">,</span> <span class="number">30</span>));
painter<span class="operator">.</span>drawText(rect()<span class="operator">,</span> <span class="type"><a href="qt.html">Qt</a></span><span class="operator">.</span>AlignCenter<span class="operator">,</span> <span class="string">"Qt"</span>);
}
</pre>
<p>The core functionality of QPainter is drawing, but the class
also provide several functions that allows you to customize
QPainter's settings and its rendering quality, and others that
enable clipping. In addition you can control how different shapes
are merged together by specifying the painter's composition
mode.</p>
<p>The <a href="qpainter.html#isActive">isActive</a>() function
indicates whether the painter is active. A painter is activated by
the <a href="qpainter.html#begin">begin</a>() function and the
constructor that takes a <a href="qpaintdevice.html">QPaintDevice</a> argument. The <a href="qpainter.html#end">end</a>() function, and the destructor,
deactivates it.</p>
<p>Together with the <a href="qpaintdevice.html">QPaintDevice</a>
and <a href="qpaintengine.html">QPaintEngine</a> classes, QPainter
form the basis for Qt's paint system. QPainter is the class used to
perform drawing operations. <a href="qpaintdevice.html">QPaintDevice</a> represents a device that can
be painted on using a QPainter. <a href="qpaintengine.html">QPaintEngine</a> provides the interface that
the painter uses to draw onto different types of devices. If the
painter is active, <a href="qpainter.html#device">device</a>()
returns the paint device on which the painter paints, and <a href="qpainter.html#paintEngine">paintEngine</a>() returns the paint
engine that the painter is currently operating on. For more
information, see the <a href="paintsystem.html">Paint
System</a>.</p>
<p>Sometimes it is desirable to make someone else paint on an
unusual <a href="qpaintdevice.html">QPaintDevice</a>. QPainter
supports a static function to do this, <a class="obsolete" href="qpainter-obsolete.html#setRedirected">setRedirected</a>().</p>
<p><b>Warning:</b> When the paintdevice is a widget, QPainter can
only be used inside a paintEvent() function or in a function called
by paintEvent(); that is unless the <a href="qt.html#WidgetAttribute-enum">Qt.WA_PaintOutsidePaintEvent</a>
widget attribute is set. On Mac OS X and Windows, you can only
paint in a paintEvent() function regardless of this attribute's
setting.</p>
<a id="settings" name="settings" />
<h3>Settings</h3>
<p>There are several settings that you can customize to make
QPainter draw according to your preferences:</p>
<ul>
<li><a href="qpainter.html#font">font</a>() is the font used for
drawing text. If the painter <a href="qpainter.html#isActive">isActive</a>(), you can retrieve
information about the currently set font, and its metrics, using
the <a href="qpainter.html#fontInfo">fontInfo</a>() and <a href="qpainter.html#fontMetrics">fontMetrics</a>() functions
respectively.</li>
<li><a href="qpainter.html#brush">brush</a>() defines the color or
pattern that is used for filling shapes.</li>
<li><a href="qpainter.html#pen">pen</a>() defines the color or
stipple that is used for drawing lines or boundaries.</li>
<li><a href="qpainter.html#backgroundMode">backgroundMode</a>()
defines whether there is a <a href="qpainter.html#background">background</a>() or not, i.e it is
either <a href="qt.html#BGMode-enum">Qt.OpaqueMode</a> or <a href="qt.html#BGMode-enum">Qt.TransparentMode</a>.</li>
<li><a href="qpainter.html#background">background</a>() only
applies when <a href="qpainter.html#backgroundMode">backgroundMode</a>() is <a href="qt.html#BGMode-enum">Qt.OpaqueMode</a> and <a href="qpainter.html#pen">pen</a>() is a stipple. In that case, it
describes the color of the background pixels in the stipple.</li>
<li><a href="qpainter.html#brushOrigin">brushOrigin</a>() defines
the origin of the tiled brushes, normally the origin of widget's
background.</li>
<li><a href="qpainter.html#viewport">viewport</a>(), <a href="qpainter.html#window">window</a>(), <a href="qpainter.html#worldTransform">worldTransform</a>() make up the
painter's coordinate transformation system. For more information,
see the <a href="#coordinate-transformations">Coordinate
Transformations</a> section and the <a href="coordsys.html">Coordinate System</a> documentation.</li>
<li><a href="qpainter.html#hasClipping">hasClipping</a>() tells
whether the painter clips at all. (The paint device clips, too.) If
the painter clips, it clips to <a href="qpainter.html#clipRegion">clipRegion</a>().</li>
<li><a href="qpainter.html#layoutDirection">layoutDirection</a>()
defines the layout direction used by the painter when drawing
text.</li>
<li><a href="qpainter.html#worldMatrixEnabled">worldMatrixEnabled</a>() tells
whether world transformation is enabled.</li>
<li><a href="qpainter.html#viewTransformEnabled">viewTransformEnabled</a>()
tells whether view transformation is enabled.</li>
</ul>
<p>Note that some of these settings mirror settings in some paint
devices, e.g. <a href="qwidget.html#font-prop">QWidget.font</a>().
The <a href="qpainter.html#begin">QPainter.begin</a>() function
(or equivalently the QPainter constructor) copies these attributes
from the paint device.</p>
<p>You can at any time save the QPainter's state by calling the
<a href="qpainter.html#save">save</a>() function which saves all
the available settings on an internal stack. The <a href="qpainter.html#restore">restore</a>() function pops them back.</p>
<a id="drawing" name="drawing" />
<h3>Drawing</h3>
<p>QPainter provides functions to draw most primitives: <a href="qpainter.html#drawPoint">drawPoint</a>(), <a href="qpainter.html#drawPoints">drawPoints</a>(), <a href="qpainter.html#drawLine">drawLine</a>(), <a href="qpainter.html#drawRect">drawRect</a>(), <a href="qpainter.html#drawRoundedRect">drawRoundedRect</a>(), <a href="qpainter.html#drawEllipse">drawEllipse</a>(), <a href="qpainter.html#drawArc">drawArc</a>(), <a href="qpainter.html#drawPie">drawPie</a>(), <a href="qpainter.html#drawChord">drawChord</a>(), <a href="qpainter.html#drawPolyline">drawPolyline</a>(), <a href="qpainter.html#drawPolygon">drawPolygon</a>(), <a href="qpainter.html#drawConvexPolygon">drawConvexPolygon</a>() and
<a class="compat" href="qpainter-qt3.html#drawCubicBezier">drawCubicBezier</a>(). The two convenience functions,
<a href="qpainter.html#drawRects">drawRects</a>() and <a href="qpainter.html#drawLines">drawLines</a>(), draw the given number of
rectangles or lines in the given array of <a href="qrect.html">QRects</a> or <a href="qline.html">QLines</a> using
the current pen and brush.</p>
<p>The QPainter class also provides the <a href="qpainter.html#fillRect">fillRect</a>() function which fills the
given <a href="qrect.html">QRect</a>, with the given <a href="qbrush.html">QBrush</a>, and the <a href="qpainter.html#eraseRect">eraseRect</a>() function that erases the
area inside the given rectangle.</p>
<p>All of these functions have both integer and floating point
versions.</p>

<p>If you need to draw a complex shape, especially if you need to
do so repeatedly, consider creating a <a href="qpainterpath.html">QPainterPath</a> and drawing it using <a href="qpainter.html#drawPath">drawPath</a>().</p>
<table class="generic" width="100%">

<p>There are functions to draw pixmaps/images, namely <a href="qpainter.html#drawPixmap">drawPixmap</a>(), <a href="qpainter.html#drawImage">drawImage</a>() and <a href="qpainter.html#drawTiledPixmap">drawTiledPixmap</a>(). Both
<a href="qpainter.html#drawPixmap">drawPixmap</a>() and <a href="qpainter.html#drawImage">drawImage</a>() produce the same result,
except that <a href="qpainter.html#drawPixmap">drawPixmap</a>() is
faster on-screen while <a href="qpainter.html#drawImage">drawImage</a>() may be faster on a
<a href="qprinter.html">QPrinter</a> or other devices.</p>
<p>Text drawing is done using <a href="qpainter.html#drawText">drawText</a>(). When you need fine-grained
positioning, <a href="qpainter.html#boundingRect">boundingRect</a>() tells you where a
given <a href="qpainter.html#drawText">drawText</a>() command will
draw.</p>
<p>There is a <a href="qpainter.html#drawPicture">drawPicture</a>()
function that draws the contents of an entire <a href="qpicture.html">QPicture</a>. The <a href="qpainter.html#drawPicture">drawPicture</a>() function is the only
function that disregards all the painter's settings as <a href="qpicture.html">QPicture</a> has its own settings.</p>
<a id="rendering-quality" name="rendering-quality" />
<h3>Rendering Quality</h3>
<p>To get the optimal rendering result using QPainter, you should
use the platform independent <a href="qimage.html">QImage</a> as
paint device; i.e. using <a href="qimage.html">QImage</a> will
ensure that the result has an identical pixel representation on any
platform.</p>
<p>The QPainter class also provides a means of controlling the
rendering quality through its <a href="qpainter.html#RenderHint-enum">RenderHint</a> enum and the support
for floating point precision: All the functions for drawing
primitives has a floating point version. These are often used in
combination with the <a href="qpainter.html#RenderHint-enum">QPainter.Antialiasing</a> render
hint.</p>
<table class="generic" width="100%">
<tr class="odd" valign="top">
<td><img alt="" src="images/qpainter-concentriccircles.png" /></td>
<td><b>Concentric Circles Example</b>
<p>The <a href="painting-concentriccircles.html">Concentric
Circles</a> example shows the improved rendering quality that can

drawing custom widgets.</p>
<p>The application's main window displays several widgets which are
drawn using the various combinations of precision and
anti-aliasing.</p>
</td>
</tr>
</table>
<p>The <a href="qpainter.html#RenderHint-enum">RenderHint</a> enum
specifies flags to QPainter that may or may not be respected by any
given engine. <a href="qpainter.html#RenderHint-enum">QPainter.Antialiasing</a>
indicates that the engine should antialias edges of primitives if
possible, <a href="qpainter.html#RenderHint-enum">QPainter.TextAntialiasing</a>
indicates that the engine should antialias text if possible, and
the <a href="qpainter.html#RenderHint-enum">QPainter.SmoothPixmapTransform</a>
indicates that the engine should use a smooth pixmap transformation
algorithm. <a href="qpainter.html#RenderHint-enum">HighQualityAntialiasing</a> is an
OpenGL-specific rendering hint indicating that the engine should
use fragment programs and offscreen rendering for antialiasing.</p>
<p>The <a href="qpainter.html#renderHints">renderHints</a>()
function returns a flag that specifies the rendering hints that are
set for this painter. Use the <a href="qpainter.html#setRenderHint">setRenderHint</a>() function to set
or clear the currently set <a href="qpainter.html#RenderHint-enum">RenderHints</a>.</p>
<a id="coordinate-transformations" name="coordinate-transformations" />
<h3>Coordinate Transformations</h3>
<p>Normally, the QPainter operates on the device's own coordinate
system (usually pixels), but QPainter has good support for
coordinate transformations.</p>
<table class="generic">
<thead>
<tr class="qt-style">
<th>nop</th>
<th><a href="qpainter.html#rotate">rotate</a>()</th>
<th><a href="qpainter.html#scale">scale</a>()</th>

<td><img alt="" src="images/qpainter-scale.png" /></td>
<td><img alt="" src="images/qpainter-translation.png" /></td>
</tr>
</table>
<p>The most commonly used transformations are scaling, rotation,
translation and shearing. Use the <a href="qpainter.html#scale">scale</a>() function to scale the coordinate
system by a given offset, the <a href="qpainter.html#rotate">rotate</a>() function to rotate it clockwise
and <a href="qpainter.html#translate">translate</a>() to translate
it (i.e. adding a given offset to the points). You can also twist
the coordinate system around the origin using the <a href="qpainter.html#shear">shear</a>() function. See the <a href="demos-affine.html">Affine Transformations</a> demo for a
visualization of a sheared coordinate system.</p>
<p>See also the <a href="painting-transformations.html">Transformations</a> example which
shows how transformations influence the way that QPainter renders
graphics primitives. In particular it shows how the order of
transformations affects the result.</p>
<table class="generic" width="100%">
<tr class="odd" valign="top">
<td><b>Affine Transformations Demo</b>
<p>The <a href="demos-affine.html">Affine Transformations</a> demo
show Qt's ability to perform affine transformations on painting
operations. The demo also allows the user to experiment with the
transformation operations and see the results immediately.</p>
</td>
<td><img alt="" src="images/qpainter-affinetransformations.png" /></td>
</tr>
</table>
<p>All the tranformation operations operate on the transformation
<a href="qpainter.html#worldTransform">worldTransform</a>(). A
matrix transforms a point in the plane to another point. For more
information about the transformation matrix, see the <a href="coordsys.html">Coordinate System</a> and <a href="qtransform.html">QTransform</a> documentation.</p>
<p>The <a href="qpainter.html#setWorldTransform">setWorldTransform</a>() function
can replace or add to the currently set <a href="qpainter.html#worldTransform">worldTransform</a>(). The <a href="qpainter.html#resetTransform">resetTransform</a>() function resets
any transformations that were made using <a href="qpainter.html#translate">translate</a>(), <a href="qpainter.html#scale">scale</a>(), <a href="qpainter.html#shear">shear</a>(), <a href="qpainter.html#rotate">rotate</a>(), <a href="qpainter.html#setWorldTransform">setWorldTransform</a>(), <a href="qpainter.html#setViewport">setViewport</a>() and <a href="qpainter.html#setWindow">setWindow</a>() functions. The <a href="qpainter.html#deviceTransform">deviceTransform</a>() returns the
matrix that transforms from logical coordinates to device
coordinates of the platform dependent paint device. The latter
function is only needed when using platform painting commands on
the platform dependent handle, and the platform does not do
transformations nativly.</p>
<p>When drawing with QPainter, we specify points using logical
coordinates which then are converted into the physical coordinates
of the paint device. The mapping of the logical coordinates to the
physical coordinates are handled by QPainter's <a href="qpainter.html#combinedTransform">combinedTransform</a>(), a
combination of <a href="qpainter.html#viewport">viewport</a>() and
<a href="qpainter.html#window">window</a>() and <a href="qpainter.html#worldTransform">worldTransform</a>(). The <a href="qpainter.html#viewport">viewport</a>() represents the physical
coordinates specifying an arbitrary rectangle, the <a href="qpainter.html#window">window</a>() describes the same rectangle in
logical coordinates, and the <a href="qpainter.html#worldTransform">worldTransform</a>() is identical
with the transformation matrix.</p>
<p>See also <a href="coordsys.html">Coordinate System</a></p>
<a id="clipping" name="clipping" />
<h3>Clipping</h3>
<p>QPainter can clip any drawing operation to a rectangle, a
region, or a vector path. The current clip is available using the
functions <a href="qpainter.html#clipRegion">clipRegion</a>() and
<a href="qpainter.html#clipPath">clipPath</a>(). Whether paths or
regions are preferred (faster) depends on the underlying <a href="qpainter.html#paintEngine">paintEngine</a>(). For example, the
<a href="qimage.html">QImage</a> paint engine prefers paths while
the X11 paint engine prefers regions. Setting a clip is done in the
painters logical coordinates.</p>
<p>After QPainter's clipping, the paint device may also clip. For
example, most widgets clip away the pixels used by child widgets,
and most printers clip away an area near the edges of the paper.
This additional clipping is not reflected by the return value of
<a href="qpainter.html#clipRegion">clipRegion</a>() or <a href="qpainter.html#hasClipping">hasClipping</a>().</p>
<a id="composition-modes" name="composition-modes" />
<h3>Composition Modes</h3>
<a id="composition-modes" name="composition-modes" />
<p>QPainter provides the <a href="qpainter.html#CompositionMode-enum">CompositionMode</a> enum which
defines the Porter-Duff rules for digital image compositing; it
describes a model for combining the pixels in one image, the
source, with the pixels in another image, the destination.</p>
<p>The two most common forms of composition are <a href="qpainter.html#CompositionMode-enum">Source</a> and <a href="qpainter.html#CompositionMode-enum">SourceOver</a>. <a href="qpainter.html#CompositionMode-enum">Source</a> is used to draw
opaque objects onto a paint device. In this mode, each pixel in the
source replaces the corresponding pixel in the destination. In
<a href="qpainter.html#CompositionMode-enum">SourceOver</a>
composition mode, the source object is transparent and is drawn on
top of the destination.</p>
<p>Note that composition transformation operates pixelwise. For
that reason, there is a difference between using the graphic
primitive itself and its bounding rectangle: The bounding rect
contains pixels with alpha == 0 (i.e the pixels surrounding the
primitive). These pixels will overwrite the other image's pixels,
affectively clearing those, while the primitive only overwrites its
own area.</p>

<h3>Limitations</h3>
<a id="limitations" name="limitations" />
<p>If you are using coordinates with Qt's raster-based paint
engine, it is important to note that, while coordinates greater
than +/- 2<sup>15</sup> can be used, any painting performed with
coordinates outside this range is not guaranteed to be shown; the
drawing may be clipped. This is due to the use of <tt>short
int</tt> in the implementation.</p>
<p>The outlines generated by Qt's stroker are only an approximation
when dealing with curved shapes. It is in most cases impossible to
represent the outline of a bezier curve segment using another
bezier curve segment, and so Qt approximates the curve outlines by
using several smaller curves. For performance reasons there is a
limit to how many curves Qt uses for these outlines, and thus when
using large pen widths or scales the outline error increases. To
generate outlines with smaller errors it is possible to use the
<a href="qpainterpathstroker.html">QPainterPathStroker</a> class,
which has the setCurveThreshold member function which let's the
user specify the error tolerance. Another workaround is to convert
the paths to polygons first and then draw the polygons instead.</p>
<a id="performance" name="performance" />
<h3>Performance</h3>
<p>QPainter is a rich framework that allows developers to do a
great variety of graphical operations, such as gradients,
composition modes and vector graphics. And QPainter can do this
across a variety of different hardware and software stacks.
Naturally the underlying combination of hardware and software has
some implications for performance, and ensuring that every single
operation is fast in combination with all the various combinations
of composition modes, brushes, clipping, transformation, etc, is
close to an impossible task because of the number of permutations.
As a compromise we have selected a subset of the QPainter API and
backends, where performance is guaranteed to be as good as we can
sensibly get it for the given combination of hardware and
software.</p>
<p>The backends we focus on as high-performance engines are:</p>
<ul>
<li>Raster - This backend implements all rendering in pure software
and is always used to render into QImages. For optimal performance
only use the format types <a href="qimage.html#Format-enum">QImage.Format_ARGB32_Premultiplied</a>,
<a href="qimage.html#Format-enum">QImage.Format_RGB32</a> or
<a href="qimage.html#Format-enum">QImage.Format_RGB16</a>. Any
other format, including <a href="qimage.html#Format-enum">QImage.Format_ARGB32</a>, has
significantly worse performance. This engine is also used by
default on Windows and on QWS. It can be used as default graphics
system on any OS/hardware/software combination by passing
<tt>-graphicssystem raster</tt> on the command line</li>
<li>OpenGL 2.0 (ES) - This backend is the primary backend for
hardware accelerated graphics. It can be run on desktop machines
and embedded devices supporting the OpenGL 2.0 or OpenGL/ES 2.0
specification. This includes most graphics chips produced in the
last couple of years. The engine can be enabled by using QPainter
onto a <a href="qglwidget.html">QGLWidget</a> or by passing
<tt>-graphicssystem opengl</tt> on the command line when the
underlying system supports it.</li>
<li>OpenVG - This backend implements the Khronos standard for 2D
and Vector Graphics. It is primarily for embedded devices with
hardware support for OpenVG. The engine can be enabled by passing
<tt>-graphicssystem openvg</tt> on the command line when the
underlying system supports it.</li>
</ul>
<p>These operations are:</p>
<ul>
<li>Simple transformations, meaning translation and scaling, pluss
0, 90, 180, 270 degree rotations.</li>
<li><tt>drawPixmap()</tt> in combination with simple
transformations and opacity with non-smooth transformation mode
(<tt>QPainter.SmoothPixmapTransform</tt> not enabled as a render
hint).</li>
<li>Rectangle fills with solid color, two-color linear gradients
and simple transforms.</li>
<li>Rectangular clipping with simple transformations and intersect
clip.</li>
<li>Composition Modes <tt>QPainter.CompositionMode_Source</tt> and
<a href="qpainter.html#CompositionMode-enum">QPainter.CompositionMode_SourceOver</a></li>
<li>Rounded rectangle filling using solid color and two-color
linear gradients fills.</li>
<li>3x3 patched pixmaps, via qDrawBorderPixmap.</li>
</ul>
<p>This list gives an indication of which features to safely use in
an application where performance is critical. For certain setups,
other operations may be fast too, but before making extensive use
of them, it is recommended to benchmark and verify them on the
system where the software will run in the end. There are also cases
where expensive operations are ok to use, for instance when the
result is cached in a <a href="qpixmap.html">QPixmap</a>.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="CompositionMode-enum" />QPainter.CompositionMode</h3><p>Defines the modes supported for digital image compositing.
Composition modes are used to specify how the pixels in one image,
the source, are merged with the pixel in another image, the
destination.</p>
<p>Please note that the bitwise raster operation modes, denoted
with a RasterOp prefix, are only natively supported in the X11 and
raster paint engines. This means that the only way to utilize these
modes on the Mac is via a <a href="qimage.html">QImage</a>. The
RasterOp denoted blend modes are <i>not</i> supported for pens and
brushes with alpha components. Also, turning on the <a href="qpainter.html#RenderHint-enum">QPainter.Antialiasing</a> render
hint will effectively disable the RasterOp modes.</p>
<p class="centerAlign"><img alt="" src="images/qpainter-compositionmode1.png" /></p>
<p class="centerAlign"><img alt="" src="images/qpainter-compositionmode2.png" /></p>
<p>The most common type is SourceOver (often referred to as just
alpha blending) where the source pixel is blended on top of the
destination pixel in such a way that the alpha component of the
source defines the translucency of the pixel.</p>
<p>When the paint device is a <a href="qimage.html">QImage</a>, the
image format must be set to <a href="qimage.html#Format-enum">Format_ARGB32Premultiplied</a> or
<a href="qimage.html#Format-enum">Format_ARGB32</a> for the
composition modes to have any effect. For performance the
premultiplied version is the preferred format.</p>
<p>When a composition mode is set it applies to all painting
operator, pens, brushes, gradients and pixmap/image drawing.</p>

<p>This constructor is convenient for short-lived painters, e.g. in
a <a href="qwidget.html#paintEvent">QWidget.paintEvent</a>() and
should be used only once. The constructor calls <a href="qpainter.html#begin">begin</a>() for you and the <a href="qpainter.html">QPainter</a> destructor automatically calls
<a href="qpainter.html#end">end</a>().</p>
<p>Here's an example using <a href="qpainter.html#begin">begin</a>() and <a href="qpainter.html#end">end</a>():</p>
<pre class="cpp">

}
</pre>
<p>Since the constructor cannot provide feedback when the
initialization of the painter failed you should rather use <a href="qpainter.html#begin">begin</a>() and <a href="qpainter.html#end">end</a>() to paint on external devices, e.g.

<p>The text will be drawn using the font and the transformation set
on the painter. If the font and/or transformation set on the
painter are different from the ones used to initialize the layout
of the <a href="qstatictext.html">QStaticText</a>, then the layout
will have to be recalculated. Use <a href="qstatictext.html#prepare">QStaticText.prepare</a>() to initialize
<i>staticText</i> with the font and transformation with which it
will later be drawn.</p>
<p>If <i>topLeftPosition</i> is not the same as when
<i>staticText</i> was initialized, or when it was last drawn, then
there will be a slight overhead when translating the text to its
new position.</p>
<p><b>Note:</b> If the painter's transformation is not affine, then
<i>staticText</i> will be drawn using regular calls to <a href="qpainter.html#drawText">drawText</a>(), losing any potential for
performance improvement.</p>

direction, beginning at the given <i>position</i>.</p>
<p>This function does not handle the newline character (\n), as it
cannot break text into multiple lines, and it cannot display the
newline character. Use the QPainter.drawText() overload that takes
a rectangle instead if you want to draw multiple lines of text with
the newline character, or if you want the text to be wrapped.</p>
