<hr><a name="details"></a><h2>Detailed Description</h2>
The QPainter class does low-level painting e.g. on widgets.
<p>
<p> The painter provides highly optimized functions to do most of the
drawing GUI programs require. QPainter 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.
<p> The typical use of a painter is:
<p> <ul>
<li> Construct a painter.
<li> Set a pen, a brush etc.
<li> Draw.
<li> Destroy the painter.
</ul>
<p> Mostly, all this is done inside a paint event. (In fact, 99% of
all QPainter use is in a reimplementation of
<a href="qwidget.html#paintEvent">QWidget::paintEvent</a>(), and the painter is heavily optimized for
such use.) Here's one very simple example:
<p> <pre>
void SimpleExampleWidget::paintEvent()
{
QPainter paint( this );
paint.<a href="#setPen">setPen</a>( Qt::blue );
paint.<a href="#drawText">drawText</a>( rect(), AlignCenter, "The Text" );
}
</pre>
<p> Usage is simple, and there are many settings you can use:
<p> <ul>
<p> <li> <a href="#font">font</a>() is the currently set font. If you set a font that isn't
available, Qt finds a close match. In fact font() returns what
you set using <a href="#setFont">setFont</a>() and <a href="#fontInfo">fontInfo</a>() returns the font actually
being used (which may be the same).
<p> <li> <a href="#brush">brush</a>() is the currently set brush; the color or pattern that's
used for filling e.g. circles.
<p> <li> <a href="#pen">pen</a>() is the currently set pen; the color or stipple that's
used for drawing lines or boundaries.
<p> <li> <a href="#backgroundMode">backgroundMode</a>() is <tt>Opaque</tt> or <tt>Transparent</tt>, i.e. whether
<a href="#backgroundColor">backgroundColor</a>() is used or not.
<p> <li> backgroundColor() only applies when backgroundMode() is Opaque
and pen() is a stipple. In that case, it describes the color of
the background pixels in the stipple.
<p> <li> <a href="#rasterOp">rasterOp</a>() is how pixels drawn interact with the pixels already
there.
<p> <li> <a href="#brushOrigin">brushOrigin</a>() is the origin of the tiled brushes, normally the
origin of the window.
<p> <li> <a href="#viewport">viewport</a>(), <a href="#window">window</a>(), <a href="#worldMatrix">worldMatrix</a>() and many more make up the
painter's coordinate transformation system. See <a href="coordsys.html">The Coordinate System</a> for an explanation of
this, or see below for a very brief overview of the functions.
<p> <li> <a href="#hasClipping">hasClipping</a>() is whether the painter clips at all. (The paint
device clips, too.) If the painter clips, it clips to <a href="#clipRegion">clipRegion</a>().
<p> <li> <a href="#pos">pos</a>() is the current position, set by <a href="#moveTo">moveTo</a>() and used by
<a href="#lineTo">lineTo</a>().
<p> </ul>
<p> Note that some of these settings mirror settings in some paint
devices, e.g. <a href="qwidget.html#font">QWidget::font</a>(). <a href="#begin">QPainter::begin</a>() (or the QPainter
constructor) copies these attributes from the paint device.
Calling, for example, <a href="qwidget.html#setFont">QWidget::setFont</a>() doesn't take effect until
the next time a painter begins painting on it.
<p> <a href="#save">save</a>() saves all of these settings on an internal stack, <a href="#restore">restore</a>()
pops them back.
<p> The core functionality of QPainter is drawing, and there are
functions to draw most primitives: <a href="#drawPoint">drawPoint</a>(), <a href="#drawPoints">drawPoints</a>(),
<a href="#drawLine">drawLine</a>(), <a href="#drawRect">drawRect</a>(), <a href="#drawWinFocusRect">drawWinFocusRect</a>(), <a href="#drawRoundRect">drawRoundRect</a>(),
<a href="#drawEllipse">drawEllipse</a>(), <a href="#drawArc">drawArc</a>(), <a href="#drawPie">drawPie</a>(), <a href="#drawChord">drawChord</a>(),
<a href="#drawLineSegments">drawLineSegments</a>(), <a href="#drawPolyline">drawPolyline</a>(), <a href="#drawPolygon">drawPolygon</a>(),
<a href="#drawConvexPolygon">drawConvexPolygon</a>() and <a href="#drawCubicBezier">drawCubicBezier</a>(). All of these functions
take integer coordinates; there are no floating-point versions
since we want drawing to be as fast as possible.
<p> There are functions to draw pixmaps/images, namely <a href="#drawPixmap">drawPixmap</a>(),
<a href="#drawImage">drawImage</a>() and <a href="#drawTiledPixmap">drawTiledPixmap</a>(). drawPixmap() and drawImage()
produce the same result, except that drawPixmap() is faster
on-screen and drawImage() faster and sometimes better on <a href="qprinter.html">QPrinter</a>
and <a href="qpicture.html">QPicture</a>.
<p> Text drawing is done using <a href="#drawText">drawText</a>(), and when you need
fine-grained positioning, <a href="#boundingRect">boundingRect</a>() tells you where a given
drawText() command would draw.
<p> There is a <a href="#drawPicture">drawPicture</a>() function that draws the contents of an
entire QPicture using this painter. drawPicture() is the only
function that disregards all the painter's settings: the QPicture
has its own settings.
<p> Normally, the QPainter operates on the device's own coordinate
system (usually pixels), but QPainter has good support for
coordinate transformation. See <a href="coordsys.html">The Coordinate
System</a> for a more general overview and a simple example.
<p> The most common functions used are <a href="#scale">scale</a>(), <a href="#rotate">rotate</a>(), <a href="#translate">translate</a>()
and <a href="#shear">shear</a>(), all of which operate on the <a href="#worldMatrix">worldMatrix</a>().
<a href="#setWorldMatrix">setWorldMatrix</a>() can replace or add to the currently set
worldMatrix().
<p> <a href="#setViewport">setViewport</a>() sets the rectangle on which QPainter operates. The
default is the entire device, which is usually fine, except on
printers. <a href="#setWindow">setWindow</a>() sets the coordinate system, that is, the
rectangle that maps to <a href="#viewport">viewport</a>(). What's drawn inside the
<a href="#window">window</a>() ends up being inside the viewport(). The window's
default is the same as the viewport, and if you don't use the
transformations, they are optimized away, gaining another little
bit of speed.
<p> After all the coordinate transformation is done, QPainter can clip
the drawing to an arbitrary rectangle or region. <a href="#hasClipping">hasClipping</a>() is
TRUE if QPainter clips, and <a href="#clipRegion">clipRegion</a>() returns the clip region.
You can set it using either <a href="#setClipRegion">setClipRegion</a>() or <a href="#setClipRect">setClipRect</a>().
Note that the clipping can be slow. It's all system-dependent,
but as a rule of thumb, you can assume that drawing speed is
inversely proportional to the number of rectangles in the clip
region.
<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
clipRegion() or hasClipping().
<p> QPainter also includes some less-used functions that are very
useful on those occasions when they're needed.
<p> <a href="#isActive">isActive</a>() indicates whether the painter is active. <a href="#begin">begin</a>() (and
the most usual constructor) makes it active. <a href="#end">end</a>() (and the
destructor) deactivates it. If the painter is active, <a href="#device">device</a>()
returns the paint device on which the painter paints.
<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 href="#redirect">redirect</a>(). We recommend not using it, but for some hacks it's
perfect.
<p> <a href="#setTabStops">setTabStops</a>() and <a href="#setTabArray">setTabArray</a>() can change where the tab stops
are, but these are very seldomly used.
<p> <b>Warning:</b> Note that QPainter does not attempt to work around
coordinate limitations in the underlying window system. Some
platforms may behave incorrectly with coordinates as small as
+/-4000.

<h3 class=fn><a name="QPainter"></a>QPainter::QPainter ()
</h3>
Constructs a painter.
<p> Notice that all painter settings (setPen, setBrush etc.) are reset
to default values when <a href="#begin">begin</a>() is called.
<p> <p>See also <a href="#begin">begin</a>() and <a href="#end">end</a>().
<h3 class=fn><a name="QPainter-2"></a>QPainter::QPainter ( const <a href="qpaintdevice.html">QPaintDevice</a> * pd, bool unclipped = FALSE )
</h3>
Constructs a painter that begins painting the paint device <em>pd</em>
immediately. Depending on the underlying graphic system the
painter will paint over children of the paintdevice if <em>unclipped</em> is TRUE.
<p> This constructor is convenient for short-lived painters, e.g. in a
<a href="qwidget.html#paintEvent">paint event</a> and should be used
only once. The constructor calls <a href="#begin">begin</a>() for you and the QPainter
destructor automatically calls <a href="#end">end</a>().
<p> Here's an example using begin() and end():
<pre>
void MyWidget::paintEvent( <a href="qpaintevent.html">QPaintEvent</a> * )
{
QPainter p;
p.<a href="#begin">begin</a>( this );
p.<a href="#drawLine">drawLine</a>( ... ); // drawing code
p.<a href="#end">end</a>();
}
</pre>
<p> The same example using this constructor:
<pre>
void MyWidget::paintEvent( <a href="qpaintevent.html">QPaintEvent</a> * )
{
QPainter p( this );
p.<a href="#drawLine">drawLine</a>( ... ); // drawing code
}
</pre>
<p> Since the constructor cannot provide feedback when the initialization
of the painter failed you should rather use begin() and end() to paint
on external devices, e.g. printers.

</h3>
Constructs a painter that begins painting the paint device <em>pd</em>
immediately, with the default arguments taken from <em>copyAttributes</em>. The painter will paint over children of the paint
device if <em>unclipped</em> is TRUE (although this is not supported on
all platforms).
<p> <p>See also <a href="#begin">begin</a>().
<h3 class=fn><a name="~QPainter"></a>QPainter::~QPainter ()
</h3>
Destroys the painter.
<h3 class=fn>const <a href="qcolor.html">QColor</a> & <a name="backgroundColor"></a>QPainter::backgroundColor () const

<h3 class=fn><a href="qt.html#BGMode-enum">BGMode</a> <a name="backgroundMode"></a>QPainter::backgroundMode () const
</h3>
<p> Returns the current background mode.

<h3 class=fn>bool <a name="begin"></a>QPainter::begin ( const <a href="qpaintdevice.html">QPaintDevice</a> * pd, bool unclipped = FALSE )
</h3>
Begins painting the paint device <em>pd</em> and returns TRUE if
successful; otherwise returns FALSE. If <em>unclipped</em> is TRUE, the
painting will not be clipped at the paint device's boundaries,
(although this is not supported by all platforms).
<p> The errors that can occur are serious problems, such as these:
<p> <pre>
p->begin( 0 ); // impossible - paint device cannot be 0
<a href="qpixmap.html">QPixmap</a> pm( 0, 0 );
p->begin( pm ); // impossible - pm.<a href="qpixmap.html#isNull">isNull</a>();
p->begin( myWidget );
p2->begin( myWidget ); // impossible - only one painter at a time
</pre>
<p> Note that most of the time, you can use one of the constructors
instead of <a href="#begin">begin</a>(), and that <a href="#end">end</a>() is automatically done at
destruction.
<p> <b>Warning:</b> A paint device can only be painted by one painter at a

</h3>
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
<p> This version opens the painter on a paint device <em>pd</em> and sets
the initial pen, background color and font from <em>copyAttributes</em>,
painting over the paint device's children when <em>unclipped</em> is
TRUE. This is equivalent to:
<p> <pre>
QPainter p;
p.<a href="#begin">begin</a>( pd );
p.<a href="#setPen">setPen</a>( copyAttributes->foregroundColor() );
p.<a href="#setBackgroundColor">setBackgroundColor</a>( copyAttributes->backgroundColor() );
p.<a href="#setFont">setFont</a>( copyAttributes->font() );
</pre>
<p> This begin function is convenient for double buffering. When you
draw in a pixmap instead of directly in a widget (to later bitBlt
the pixmap into the widget) you will need to set the widget's
font etc. This function does exactly that.
<p> Example:
<pre>
void MyWidget::paintEvent( <a href="qpaintevent.html">QPaintEvent</a> * )
{
<a href="qpixmap.html">QPixmap</a> pm(size());
QPainter p;
p.<a href="#begin">begin</a>(&pm, this);

<h3 class=fn>void <a name="setWorldMatrix"></a>QPainter::setWorldMatrix ( const <a href="qwmatrix.html">QWMatrix</a> & m, bool combine = FALSE )
</h3>
Sets the world <a href="qwmatrix.html#TransformationMode">transformation matrix</a> to <em>m</em> and enables world
transformation.
<p> If <em>combine</em> is TRUE, then <em>m</em> is combined with the current
transformation matrix, otherwise <em>m</em> replaces the current
transformation matrix.
<p> If <em>m</em> is the identity matrix and <em>combine</em> is FALSE, this
function calls <a href="#setWorldXForm">setWorldXForm</a>(FALSE). (The identity matrix is the
matrix where <a href="qwmatrix.html#m11">QWMatrix::m11</a>() and <a href="qwmatrix.html#m22">QWMatrix::m22</a>() are 1.0 and the
rest are 0.0.)
<p> World transformations are applied after the view transformations
(i.e. <a href="#setWindow">window</a> and <a href="#setViewport">viewport</a>).
<p> The following functions can transform the coordinate system without using
a QWMatrix:
<ul>
<li> <a href="#translate">translate</a>()
<li> <a href="#scale">scale</a>()
<li> <a href="#shear">shear</a>()
<li> <a href="#rotate">rotate</a>()
</ul>
<p> They operate on the painter's <a href="#worldMatrix">worldMatrix</a>() and are implemented like this:
<p> <pre>
void QPainter::rotate( double a )
{
<a href="qwmatrix.html">QWMatrix</a> m;
m.<a href="qwmatrix.html#rotate">rotate</a>( a );
<a href="#setWorldMatrix">setWorldMatrix</a>( m, TRUE );
}
</pre>
<p> Note that you should always use <em>combine</em> when you are drawing
into a <a href="qpicture.html">QPicture</a>. Otherwise it may not be possible to replay the
picture with additional transformations. Using translate(),
scale(), etc., is safe.
