Member Function Documentation

◆ boundingRect()

QRectF BackgroundColorItem::boundingRect ( ) const

overridevirtual

Returns: An invalid bounding rect: QRectF(1.0, 1.0, -2.0, -2.0)

Note: A width or height < 0.0 is ignored by the autoscaler

Reimplemented from QwtPlotItem.

Definition at line 72 of file plot_background.cpp.

◆ colormapName()

QString BackgroundColorItem::colormapName ( ) const

inline

Definition at line 38 of file plot_background.h.

◆ dataName()

QString BackgroundColorItem::dataName ( ) const

inline

Definition at line 43 of file plot_background.h.

◆ draw()

void BackgroundColorItem::draw	(	QPainter *	painter,
		const QwtScaleMap &	xMap,
		const QwtScaleMap &	yMap,
		const QRectF &	canvasRect
	)		const

overridevirtual

Draw the item.

Parameters

painter	Painter
xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.
canvasRect	Contents rect of the canvas in painter coordinates

Implements QwtPlotItem.

Definition at line 18 of file plot_background.cpp.

◆ rtti()

int BackgroundColorItem::rtti ( ) const

inlineoverridevirtual

Return rtti for the specific class represented. QwtPlotItem is simply a virtual interface class, and base classes will implement this method with specific rtti values so a user can differentiate them.

The rtti value is useful for environments, where the runtime type information is disabled and it is not possible to do a dynamic_cast<...>.

Returns: rtti value

Reimplemented from QwtPlotItem.

◆ setTimeOffset()

void BackgroundColorItem::setTimeOffset ( double * time_offset )

inline

Definition at line 23 of file plot_background.h.
