DESCRIPTION

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.
