.SH DESCRIPTION
|
|
The TQBrush class defines the fill pattern of shapes drawn by a TQPainter.
|
|
.PP
|
|
A brush has a style and a color. One of the brush styles is a custom pattern, which is defined by a TQPixmap.
|
|
.PP
|
|
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.
|
|
.PP
|
|
The brush color defines the color of the fill pattern. The TQColor documentation lists the predefined colors.
|
|
.PP
|
|
Use the TQPen class for specifying line/outline styles.
|
|
.PP
|
|
Example:
|
|
.PP
|
|
.nf
|
|
.br
|
|
TQPainter painter;
|
|
.br
|
|
TQBrush brush( yellow ); // yellow solid pattern
|
|
.br
|
|
painter.begin( &anyPaintDevice ); // paint something
|
|
.br
|
|
painter.setBrush( brush ); // set the yellow brush
|
|
.br
|
|
painter.setPen( NoPen ); // do not draw outline
|
|
.br
|
|
painter.drawRect( 40,30, 200,100 ); // draw filled rectangle
|
|
.br
|
|
painter.setBrush( NoBrush ); // do not fill
|
|
.br
|
|
painter.setPen( black ); // set black pen, 0 pixel width
|
|
.br
|
|
painter.drawRect( 10,10, 30,20 ); // draw rectangle outline
|
|
.br
|
|
painter.end(); // painting done

.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "TQBrush::TQBrush ()"
|
|
Constructs a default black brush with the style NoBrush (will not fill shapes).
|
|
.SH "TQBrush::TQBrush ( BrushStyle style )"
|
|
Constructs a black brush with the style \fIstyle\fR.
|
|
.PP
|
|
See also setStyle().
|
|
.SH "TQBrush::TQBrush ( const TQColor & color, BrushStyle style = SolidPattern )"
|
|
Constructs a brush with the color \fIcolor\fR and the style \fIstyle\fR.
|
|
.PP
|
|
See also setColor() and setStyle().
|
|
.SH "TQBrush::TQBrush ( const TQColor & color, const TQPixmap & pixmap )"
|
|
Constructs a brush with the color \fIcolor\fR and a custom pattern stored in \fIpixmap\fR.
|
|
.PP
|
|
The color will only have an effect for monochrome pixmaps, i.e. for TQPixmap::depth() == 1.
|
|
.PP
|
|
Pixmap brushes are currently not supported when printing on X11.
|
|
.PP
|
|
See also setColor() and setPixmap().
|
|
.SH "TQBrush::TQBrush ( const TQBrush & b )"
|
|
Constructs a brush that is a shallow copy of \fIb\fR.
|
|
.SH "TQBrush::~TQBrush ()"
|
|
Destroys the brush.
|
|
.SH "const TQColor & TQBrush::color () const"
|
|
Returns the brush color.
|
|
.PP
|
|
See also setColor().
|
|
.SH "bool TQBrush::operator!= ( const TQBrush & b ) const"
|
|
Returns TRUE if the brush is different from \fIb\fR; otherwise returns FALSE.
|
|
.PP
|
|
Two brushes are different if they have different styles, colors or pixmaps.
|
|
.PP
|
|
See also operator==().
|
|
.SH "TQBrush & TQBrush::operator= ( const TQBrush & b )"
|
|
Assigns \fIb\fR to this brush and returns a reference to this brush.
|
|
.SH "bool TQBrush::operator== ( const TQBrush & b ) const"
|
|
Returns TRUE if the brush is equal to \fIb\fR; otherwise returns FALSE.
|
|
.PP
|
|
Two brushes are equal if they have equal styles, colors and pixmaps.
|
|
.PP
|
|
See also operator!=().
|
|
.SH "TQPixmap * TQBrush::pixmap () const"
|
|
Returns a pointer to the custom brush pattern, or 0 if no custom brush pattern has been set.
|
|
.PP
|
|
See also setPixmap().
|
|
.PP
|
|
Example: richtext/richtext.cpp.
|
|
.SH "void TQBrush::setColor ( const TQColor & c )"
|
|
Sets the brush color to \fIc\fR.
|
|
.PP
|
|
See also color() and setStyle().
|
|
.PP
|
|
Example: picture/picture.cpp.
|
|
.SH "void TQBrush::setPixmap ( const TQPixmap & pixmap )"
|
|
Sets the brush pixmap to \fIpixmap\fR. The style is set to CustomPattern.
|
|
.PP
|
|
The current brush color will only have an effect for monochrome pixmaps, i.e. for TQPixmap::depth() == 1.
|
|
.PP
|
|
Pixmap brushes are currently not supported when printing on X11.
|
|
.PP
|
|

|
|
.PP
|
|
Example: richtext/richtext.cpp.
|
|
.SH "void TQBrush::setStyle ( BrushStyle s )"
|
|
Sets the brush style to \fIs\fR.
|
|
.PP
|
|
The brush styles are: <center>.nf
|
|
.TS
|

l - l. 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.
