Detailed Description

A drawing primitive for displaying an interval like an error bar.

Member Enumeration Documentation

enum QwtIntervalSymbol::Style

Symbol style.

Enumerator:

NoSymbol	No Style. The symbol cannot be drawn.
Bar	The symbol displays a line with caps at the beginning/end. The size of the caps depends on the symbol width().
Box	The symbol displays a plain rectangle using pen() and brush(). The size of the rectangle depends on the translated interval and the width(),
UserSymbol	Styles >= UserSymbol are reserved for derived classes of QwtIntervalSymbol that overload draw() with additional application specific symbol types.

Definition at line 30 of file qwt_interval_symbol.h.

Constructor & Destructor Documentation

QwtIntervalSymbol::QwtIntervalSymbol ( Style style = NoSymbol ) [explicit]

Constructor

Parameters:

style Style of the symbol

See also:: setStyle(), style(), Style

Definition at line 51 of file qwt_interval_symbol.cpp.

QwtIntervalSymbol::QwtIntervalSymbol ( const QwtIntervalSymbol & other )

Copy constructor.

Definition at line 58 of file qwt_interval_symbol.cpp.

QwtIntervalSymbol::~QwtIntervalSymbol ( ) [virtual]

Destructor.

Definition at line 65 of file qwt_interval_symbol.cpp.

Member Function Documentation

const QBrush & QwtIntervalSymbol::brush ( ) const

Returns:: Brush

See also:: setBrush()

Definition at line 150 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::draw	(	QPainter *	painter,
		Qt::Orientation	orientation,
		const QPointF &	from,
		const QPointF &	to
	)		const `[virtual]`

Draw a symbol depending on its style

Parameters:

painter	Painter
orientation	Orientation
from	Start point of the interval in target device coordinates
to	End point of the interval in target device coordinates

See also:: setStyle()

Definition at line 204 of file qwt_interval_symbol.cpp.

bool QwtIntervalSymbol::operator!= ( const QwtIntervalSymbol & other ) const

Compare two symbols.

Definition at line 86 of file qwt_interval_symbol.cpp.

QwtIntervalSymbol & QwtIntervalSymbol::operator= ( const QwtIntervalSymbol & other )

Assignment operator.

Definition at line 71 of file qwt_interval_symbol.cpp.

bool QwtIntervalSymbol::operator== ( const QwtIntervalSymbol & other ) const

Compare two symbols.

Definition at line 79 of file qwt_interval_symbol.cpp.

const QPen & QwtIntervalSymbol::pen ( ) const

Returns:: Pen

See also:: setPen(), brush()

Definition at line 189 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::setBrush ( const QBrush & brush )

Assign a brush.

The brush is used for the Box style.

Parameters:

brush Brush

See also:: brush()

Definition at line 141 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::setPen	(	const QColor &	color,
		qreal	width = `0.0`,
		Qt::PenStyle	style = `Qt::SolidLine`
	)

Build and assign a pen

In Qt5 the default pen width is 1.0 ( 0.0 in Qt4 ) what makes it non cosmetic ( see QPen::isCosmetic() ). This method has been introduced to hide this incompatibility.

Parameters:

color	Pen color
width	Pen width
style	Pen style

See also:: pen(), brush()

Definition at line 168 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::setPen ( const QPen & pen )

Assign a pen

Parameters:

pen Pen

See also:: pen(), setBrush()

Definition at line 180 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::setStyle ( Style style )

Specify the symbol style

Parameters:

style Style

See also:: style(), Style

Definition at line 98 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::setWidth ( int width )

Specify the width of the symbol It is used depending on the style.

Parameters:

width Width

See also:: width(), setStyle()

Definition at line 119 of file qwt_interval_symbol.cpp.

QwtIntervalSymbol::Style QwtIntervalSymbol::style ( ) const

Returns:: Current symbol style

See also:: setStyle()

Definition at line 107 of file qwt_interval_symbol.cpp.

int QwtIntervalSymbol::width ( ) const

Returns:: Width of the symbol.

See also:: setWidth(), setStyle()
