\class QPen
\ingroup painting
\ingroup shared
\brief The QPen class defines how a QPainter should draw lines and outlines
of shapes.
A pen has a style(), width(), brush(), capStyle() and joinStyle().
The pen style defines the line type. The brush is used to fill
strokes generated with the pen. Use the QBrush class to specify
fill styles. The cap style determines the line end caps that can
be drawn using QPainter, while the join style describes how joins
between two lines are drawn. The pen width can be specified in
both integer (width()) and floating point (widthF()) precision. A
line width of zero indicates a cosmetic pen. This means that the
pen width is always drawn one pixel wide, independent of the \l
{QPainter#Coordinate Transformations}{transformation} set on the
painter.
The various settings can easily be modified using the
corresponding setStyle(), setWidth(), setBrush(), setCapStyle()
and setJoinStyle() functions (note that the painter's pen must be
reset when altering the pen's properties).
For example:
\snippet doc/src/snippets/code/src_gui_painting_qpen.cpp 0
which is equivalent to
\snippet doc/src/snippets/code/src_gui_painting_qpen.cpp 1
The default pen is a solid black brush with 0 width, square
cap style (Qt::SquareCap), and bevel join style (Qt::BevelJoin).
In addition QPen provides the color() and setColor()
convenience functions to extract and set the color of the pen's
brush, respectively. Pens may also be compared and streamed.
For more information about painting in general, see the \l{Paint
System} documentation.
\tableofcontents
\section1 Pen Style
Qt provides several built-in styles represented by the
Qt::PenStyle enum:
\table
\row
\o \inlineimage qpen-solid.png
\o \inlineimage qpen-dash.png
\o \inlineimage qpen-dot.png
\row
\o Qt::SolidLine
\o Qt::DashLine
\o Qt::DotLine
\row
\o \inlineimage qpen-dashdot.png
\o \inlineimage qpen-dashdotdot.png
\o \inlineimage qpen-custom.png
\row
\o Qt::DashDotLine
\o Qt::DashDotDotLine
\o Qt::CustomDashLine
\endtable
Simply use the setStyle() function to convert the pen style to
either of the built-in styles, except the Qt::CustomDashLine style
which we will come back to shortly. Setting the style to Qt::NoPen
tells the painter to not draw lines or outlines. The default pen
style is Qt::SolidLine.
Since Qt 4.1 it is also possible to specify a custom dash pattern
using the setDashPattern() function which implicitly converts the
style of the pen to Qt::CustomDashLine. The pattern argument, a
QVector, must be specified as an even number of \l qreal entries
where the entries 1, 3, 5... are the dashes and 2, 4, 6... are the
spaces. For example, the custom pattern shown above is created
using the following code:
\snippet doc/src/snippets/code/src_gui_painting_qpen.cpp 2
Note that the dash pattern is specified in units of the pens
width, e.g. a dash of length 5 in width 10 is 50 pixels long.
The currently set dash pattern can be retrieved using the
dashPattern() function. Use the isSolid() function to determine
whether the pen has a solid fill, or not.
\section1 Cap Style
The cap style defines how the end points of lines are drawn using
QPainter. The cap style only apply to wide lines, i.e. when the
width is 1 or greater. The Qt::PenCapStyle enum provides the
following styles:
\table
\row
\o \inlineimage qpen-square.png
\o \inlineimage qpen-flat.png
\o \inlineimage qpen-roundcap.png
\row
\o Qt::SquareCap
\o Qt::FlatCap
\o Qt::RoundCap
\endtable
The Qt::SquareCap style is a square line end that covers the end
point and extends beyond it by half the line width. The
Qt::FlatCap style is a square line end that does not cover the end
point of the line. And the Qt::RoundCap style is a rounded line
end covering the end point.
The default is Qt::SquareCap.
Whether or not end points are drawn when the pen width is 0 or 1
depends on the cap style. Using Qt::SquareCap or Qt::RoundCap they
are drawn, using Qt::FlatCap they are not drawn.
\section1 Join Style
The join style defines how joins between two connected lines can
be drawn using QPainter. The join style only apply to wide lines,
i.e. when the width is 1 or greater. The Qt::PenJoinStyle enum
provides the following styles:
\table
\row
\o \inlineimage qpen-bevel.png
\o \inlineimage qpen-miter.png
\o \inlineimage qpen-roundjoin.png
\row
\o Qt::BevelJoin
\o Qt::MiterJoin
\o Qt::RoundJoin
\endtable
The Qt::BevelJoin style fills the triangular notch between the two
lines. The Qt::MiterJoin style extends the lines to meet at an
angle. And the Qt::RoundJoin style fills a circular arc between
the two lines.
The default is Qt::BevelJoin.
\image qpen-miterlimit.png
When the Qt::MiterJoin style is applied, it is possible to use the
setMiterLimit() function to specify how far the miter join can
extend from the join point. The miterLimit() is used to reduce
artifacts between line joins where the lines are close to
parallel.
The miterLimit() must be specified in units of the pens width,
e.g. a miter limit of 5 in width 10 is 50 pixels long. The
default miter limit is 2, i.e. twice the pen width in pixels.

patterns.
