Descripción detallada

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.

Documentación del constructor y destructor

QBrush::QBrush

(

)

Constructs a default black brush with the style NoBrush (will not fill shapes).

QBrush::QBrush

(

BrushStyle

style

)

Constructs a black brush with the style style.

Ver también:

setStyle()

QBrush::QBrush	(	const QColor &	color,
		BrushStyle	style = SolidPattern
	)

Constructs a brush with the color color and the style style.

Ver también:

setColor(), setStyle()

QBrush::QBrush	(	const QColor &	color,
		const QPixmap &	pixmap
	)

Constructs a brush with the color color and a custom pattern stored in pixmap.

The color will only have an effect for monochrome pixmaps, i.e. for QPixmap::depth() == 1.

Pixmap brushes are currently not supported when printing on X11.

p

)

const

bool QBrush::operator==

(

)

const

Returns TRUE if the brush is equal to b; otherwise returns FALSE.

Two brushes are equal if they have equal styles, colors and pixmaps.

void QBrush::setPixmap

(

const QPixmap &

pixmap

)

Sets the brush pixmap to pixmap. The style is set to CustomPattern.

The current brush color will only have an effect for monochrome pixmaps, i.e. for QPixmap::depth() == 1.

Pixmap brushes are currently not supported when printing on X11.

void QBrush::setStyle

(

BrushStyle

s

)

Sets the brush style to s.

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, dense and custom patterns cannot be transparent.

See the Detailed Description for a picture of all the styles.
