Detailed Description

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

Member Enumeration Documentation

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.

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.

Returns
Pen

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
brushBrush
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
colorPen color
widthPen width
stylePen style

pen(), brush()

Definition at line 168 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::setPen ( const QPen &  pen)

Assign a pen

Parameters
penPen

pen(), setBrush()

Definition at line 180 of file qwt_interval_symbol.cpp.

void QwtIntervalSymbol::setStyle ( Style  style)

Specify the symbol style

Parameters
styleStyle

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
widthWidth

width(), setStyle()

Definition at line 119 of file qwt_interval_symbol.cpp.

QwtIntervalSymbol::Style QwtIntervalSymbol::style ( ) const
Returns
Current symbol style
