#include <qbrush.h>
Inherits Qt.
The QBrush class defines the fill pattern of shapes drawn by a QPainter.
A brush has a style and a color. One of the brush styles is a custom pattern, which is defined by a QPixmap.
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.
The brush color defines the color of the fill pattern. The QColor documentation lists the predefined colors.
Use the QPen class for specifying line/outline styles.
Example:
QPainter painter;
QBrush brush( yellow ); // yellow solid pattern
painter.begin( &anyPaintDevice ); // paint something
painter.setBrush( brush ); // set the yellow brush
painter.setPen( NoPen ); // do not draw outline
painter.drawRect( 40,30, 200,100 ); // draw filled rectangle
painter.setBrush( NoBrush ); // do not fill
painter.setPen( black ); // set black pen, 0 pixel width
painter.drawRect( 10,10, 30,20 ); // draw rectangle outline
painter.end(); // painting done
See the setStyle() function for a complete list of brush styles.

See also setStyle().
See also setColor() and setStyle().
The color will only have an effect for monochrome pixmaps, i.e. for QPixmap::depth() == 1.
See also setColor() and setPixmap().
Returns the brush color.
See also setColor().
Returns TRUE if the brush is different from b; otherwise returns FALSE.
Two brushes are different if they have different styles, colors or pixmaps.
See also operator==().
Two brushes are equal if they have equal styles, colors and pixmaps.
See also operator!=().
Returns a pointer to the custom brush pattern, or 0 if no custom brush pattern has been set.
See also setPixmap().
Example: richtext/richtext.cpp.
See also color() and setStyle().
Example: picture/picture.cpp.
The current brush color will only have an effect for monochrome pixmaps, i.e. for QPixmap::depth() == 1.
See also pixmap() and color().
Example: richtext/richtext.cpp.
The brush styles are:
| 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 | set when a pixmap pattern is being used. |
On Windows, only the dense patterns are transparent.
See the Detailed Description for a picture of all the styles.

Returns the brush style.

Writes the brush b to the stream s and returns a reference to the stream.

Reads the brush b from the stream s and returns a reference to the stream.
