Additional Inherited Members¶

QwtPlotZoneItem::QwtPlotZoneItem () [explicit]¶

Constructor. Initializes the zone with no pen and a semi transparent gray brush

Sets the following item attributes:

• QwtPlotItem::AutoScale: false
• QwtPlotItem::Legend: false

The z value is initialized by 5

QRectF QwtPlotZoneItem::boundingRect () const [override], [virtual]¶

The bounding rectangle is build from the interval in one direction and something invalid for the opposite direction.

Returns

Reimplemented from QwtPlotItem.

void QwtPlotZoneItem::draw (QPainter * painter, const QwtScaleMap & xMap, const QwtScaleMap & yMap, const QRectF & canvasRect) const [override], [virtual]¶

Draw the zone

Parameters

Implements QwtPlotItem.

int QwtPlotZoneItem::rtti () const [override], [virtual]¶

Returns

Reimplemented from QwtPlotItem.

Definition at line 68 of file qwt_plot_zoneitem.cpp.

void QwtPlotZoneItem::setBrush (const QBrush & brush)¶

Assign a brush. The brush is used to fill the zone

Parameters

See also

Definition at line 125 of file qwt_plot_zoneitem.cpp.

void QwtPlotZoneItem::setInterval (const QwtInterval & interval)¶

Set the interval of the zone

For a horizontal zone the interval is related to the y axis, for a vertical zone it is related to the x axis.

Parameters

See also

Definition at line 196 of file qwt_plot_zoneitem.cpp.

void QwtPlotZoneItem::setInterval (double min, double max)¶

Set the interval of the zone

For a horizontal zone the interval is related to the y axis, for a vertical zone it is related to the x axis.

Parameters

See also

Definition at line 181 of file qwt_plot_zoneitem.cpp.

void QwtPlotZoneItem::setOrientation (Qt::Orientation orientation)¶

Set the orientation of the zone. A horizontal zone highlights an interval of the y axis, a vertical zone of the x axis. It is unbounded in the opposite direction.

Definition at line 152 of file qwt_plot_zoneitem.cpp.

void QwtPlotZoneItem::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

Definition at line 86 of file qwt_plot_zoneitem.cpp.

void QwtPlotZoneItem::setPen (const QPen & pen)¶

Assign a pen. The pen is used to draw the border lines of the zone

Parameters
