.SH DESCRIPTION
The QBrush class defines the fill pattern of shapes drawn by a QPainter.
.PP
A brush has a style and a color. One of the brush styles is a custom pattern, which is defined by a QPixmap.
.PP
The brush style defines the fill pattern. The default brush style is NoBrush (depending on how you construct a brush). This style tells the painter to not fill shapes. The standard style for filling is SolidPattern.
.PP
The brush color defines the color of the fill pattern. The QColor documentation lists the predefined colors.
.PP
Use the QPen class for specifying line/outline styles.
.PP
Example:
.PP
.nf
.br
QPainter painter;
.br
QBrush brush( yellow ); // yellow solid pattern
.br
painter.begin( &anyPaintDevice ); // paint something
.br
painter.setBrush( brush ); // set the yellow brush
.br
painter.setPen( NoPen ); // do not draw outline
.br
painter.drawRect( 40,30, 200,100 ); // draw filled rectangle
.br
painter.setBrush( NoBrush ); // do not fill
.br
painter.setPen( black ); // set black pen, 0 pixel width
.br
painter.drawRect( 10,10, 30,20 ); // draw rectangle outline
.br
painter.end(); // painting done

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QBrush::QBrush ()"
Constructs a default black brush with the style NoBrush (will not fill shapes).
.SH "QBrush::QBrush ( BrushStyle style )"
Constructs a black brush with the style \fIstyle\fR.
.PP
See also setStyle().
.SH "QBrush::QBrush ( const QColor & color, BrushStyle style = SolidPattern )"
Constructs a brush with the color \fIcolor\fR and the style \fIstyle\fR.
.PP
See also setColor() and setStyle().
.SH "QBrush::QBrush ( const QColor & color, const QPixmap & pixmap )"
Constructs a brush with the color \fIcolor\fR and a custom pattern stored in \fIpixmap\fR.
.PP
The color will only have an effect for monochrome pixmaps, i.e. for QPixmap::depth() == 1.
.PP
Pixmap brushes are currently not supported when printing on X11.
.PP
See also setColor() and setPixmap().
.SH "QBrush::QBrush ( const QBrush & b )"
Constructs a brush that is a shallow copy of \fIb\fR.
.SH "QBrush::~QBrush ()"
Destroys the brush.
.SH "const QColor & QBrush::color () const"
Returns the brush color.
.PP
See also setColor().
.SH "bool QBrush::operator!= ( const QBrush & b ) const"
Returns TRUE if the brush is different from \fIb\fR; otherwise returns FALSE.
.PP
Two brushes are different if they have different styles, colors or pixmaps.
.PP
See also operator==().
.SH "QBrush & QBrush::operator= ( const QBrush & b )"
Assigns \fIb\fR to this brush and returns a reference to this brush.
.SH "bool QBrush::operator== ( const QBrush & b ) const"
Returns TRUE if the brush is equal to \fIb\fR; otherwise returns FALSE.
.PP
Two brushes are equal if they have equal styles, colors and pixmaps.
.PP
See also operator!=().
.SH "QPixmap * QBrush::pixmap () const"
Returns a pointer to the custom brush pattern, or 0 if no custom brush pattern has been set.
.PP
See also setPixmap().
.PP
Example: richtext/richtext.cpp.
.SH "void QBrush::setColor ( const QColor & c )"
Sets the brush color to \fIc\fR.
.PP
See also color() and setStyle().
.PP
Example: picture/picture.cpp.
.SH "void QBrush::setPixmap ( const QPixmap & pixmap )"
Sets the brush pixmap to \fIpixmap\fR. The style is set to CustomPattern.
.PP
The current brush color will only have an effect for monochrome pixmaps, i.e. for QPixmap::depth() == 1.
.PP
Pixmap brushes are currently not supported when printing on X11.
.PP
See also pixmap() and color().
.PP
Example: richtext/richtext.cpp.
.SH "void QBrush::setStyle ( BrushStyle s )"
Sets the brush style to \fIs\fR.
.PP
The brush styles are: <center>.nf
.TS
l - l. Pattern Meaning NoBrush will not fill shapes (default). SolidPattern solid (100%) fill pattern. Dense1Pattern 94% fill pattern. Dense2Pattern 88% fill pattern. Dense3Pattern 63% fill pattern. Dense4Pattern 50% fill pattern. Dense5Pattern 37% fill pattern. Dense6Pattern 12% fill pattern. Dense7Pattern 6% fill pattern. HorPattern horizontal lines pattern. VerPattern vertical lines pattern. CrossPattern crossing lines pattern. BDiagPattern diagonal lines (directed /) pattern. FDiagPattern diagonal lines (directed \) pattern. DiagCrossPattern diagonal crossing lines pattern. CustomPattern

.PP
On Windows, dense and custom patterns cannot be transparent.
.PP
See the Detailed Description for a picture of all the styles.
.PP
See also style().
.SH "BrushStyle QBrush::style () const"
Returns the brush style.
.PP
See also setStyle().
.SH RELATED FUNCTION DOCUMENTATION
.SH "QDataStream & operator<< ( QDataStream & s, const QBrush & b )"
Writes the brush \fIb\fR to the stream \fIs\fR and returns a reference to the stream.
.PP
See also Format of the QDataStream operators.
.SH "QDataStream & operator>> ( QDataStream & s, QBrush & b )"
Reads the brush \fIb\fR from the stream \fIs\fR and returns a reference to the stream.
.PP
See also Format of the QDataStream operators.
