35 The QBrush class defines the fill pattern of shapes drawn by a
36 QPainter.
37 A brush has a style and a color. One of the brush styles is a custom
39 pattern, which is defined by a QPixmap.
40 The brush style defines the fill pattern. The default brush style is
42 NoBrush (depending on how you construct a brush). This style tells the
43 painter to not fill shapes. The standard style for filling is
44 SolidPattern.
45 The brush color defines the color of the fill pattern. The QColor
47 documentation lists the predefined colors.
48 Use the QPen class for specifying line/outline styles.
50 Example:
52 QPainter painter;
54 QBrush brush( yellow ); // yellow solid pattern
55 painter.begin( &anyPaintDevice ); // paint something
56 painter.setBrush( brush ); // set the yellow brush
57 painter.setPen( NoPen ); // do not draw outline
58 painter.drawRect( 40,30, 200,100 ); // draw filled rectangle
59 painter.setBrush( NoBrush ); // do not fill
60 painter.setPen( black ); // set black pen, 0 pixel width
61 painter.drawRect( 10,10, 30,20 ); // draw rectangle outline
62 painter.end(); // painting done
63 See the setStyle() function for a complete list of brush styles.

74
77 Constructs a default black brush with the style NoBrush (will not fill
78 shapes).
79
81 Constructs a black brush with the style style.
82 See also setStyle().
84
86 Constructs a brush with the color color and the style style.
87 See also setColor() and setStyle().
89
91 Constructs a brush with the color color and a custom pattern stored in
92 pixmap.
93 The color will only have an effect for monochrome pixmaps, i.e. for
95 QPixmap::depth() == 1.
96 Pixmap brushes are currently not supported when printing on X11.
98 See also setColor() and setPixmap().
100
102 Constructs a brush that is a shallow copy of b.
103
105 Destroys the brush.
106
108 Returns the brush color.
109 See also setColor().
111
113 Returns TRUE if the brush is different from b; otherwise returns FALSE.
114 Two brushes are different if they have different styles, colors or
116 pixmaps.
117 See also operator==().
119
121 Assigns b to this brush and returns a reference to this brush.
122
124 Returns TRUE if the brush is equal to b; otherwise returns FALSE.
125 Two brushes are equal if they have equal styles, colors and pixmaps.
127 See also operator!=().
129
131 Returns a pointer to the custom brush pattern, or 0 if no custom brush
132 pattern has been set.
133 See also setPixmap().
135 Example: richtext/richtext.cpp.
137
139 Sets the brush color to c.
140 See also color() and setStyle().
142 Example: picture/picture.cpp.
144
146 Sets the brush pixmap to pixmap. The style is set to CustomPattern.
147 The current brush color will only have an effect for monochrome
149 pixmaps, i.e. for QPixmap::depth() == 1.
150 Pixmap brushes are currently not supported when printing on X11.
152 See also pixmap() and color().
154 Example: richtext/richtext.cpp.
156
158 Sets the brush style to s.
159 The brush styles are: <center>.nf
161 </center>
163 On Windows, dense and custom patterns cannot be transparent.
165 See the Detailed Description for a picture of all the styles.
167 See also style().
169
171 Returns the brush style.
172 See also setStyle().
174
177 Writes the brush b to the stream s and returns a reference to the
178 stream.
179 See also Format of the QDataStream operators.
181
183 Reads the brush b from the stream s and returns a reference to the
184 stream.
185 See also Format of the QDataStream operators.
