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.
brush-styles.png Brush Styles
| 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.
| QBrush::QBrush | ( | const QColor & | color, |
| BrushStyle | style = SolidPattern |
||
| ) |
Constructs a brush with the color color and the style style.
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.
| QBrush::QBrush | ( | const QBrush & | b | ) |
Constructs a brush that is a shallow copy of b.
| QBrush::~QBrush | ( | ) |
Destroys the brush.
| QBrush::QBrush | ( | ) |
| QBrush::QBrush | ( | BrushStyle | ) |
| QBrush::QBrush | ( | const QColor & | , |
| BrushStyle | = SolidPattern |
||
| ) |
| QBrush::QBrush | ( | const QBrush & | ) |
| QBrush::~QBrush | ( | ) |
| const QColor & QBrush::color | ( | ) | const [inline] |
Returns the brush color.
| const QColor& QBrush::color | ( | ) | const [inline] |
Returns TRUE if the brush is different from b; otherwise returns FALSE.
Two brushes are different if they have different styles, colors or pixmaps.
Assigns b to this brush and returns a reference to this brush.
Returns TRUE if the brush is equal to b; otherwise returns FALSE.
Two brushes are equal if they have equal styles, colors and pixmaps.
| QPixmap * QBrush::pixmap | ( | ) | const [inline] |
Returns a pointer to the custom brush pattern, or 0 if no custom brush pattern has been set.
| QPixmap* QBrush::pixmap | ( | ) | const [inline] |
| void QBrush::setColor | ( | const QColor & | ) |
| void QBrush::setColor | ( | const QColor & | c | ) |
Sets the brush color to c.
| 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::setPixmap | ( | const QPixmap & | ) |
| void QBrush::setStyle | ( | BrushStyle | ) |
| 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.
| BrushStyle QBrush::style | ( | ) | const [inline] |
Returns the brush style.
| BrushStyle QBrush::style | ( | ) | const [inline] |
| QDataStream & operator<< | ( | QDataStream & | s, |
| const QBrush & | b | ||
| ) | [related] |
Writes the brush b to the stream s and returns a reference to the stream.
| QDataStream & operator>> | ( | QDataStream & | s, |
| QBrush & | b | ||
| ) | [related] |
Reads the brush b from the stream s and returns a reference to the stream.
