Detailed Description

The KDReports::ChartElement class represents a chart in the report. The data is provided by a QAbstractItemModel.

Definition at line 41 of file KDReportsChartElement.h.

Constructor & Destructor Documentation

ChartElement() [1/4]

KDReports::ChartElement::ChartElement ( QAbstractItemModel *  tableModel )

explicit

Creates a chart element from the given table model.

Definition at line 68 of file KDReportsChartElement.cpp.

ChartElement() [2/4]

KDReports::ChartElement::ChartElement ( const QString &  modelKey )

explicit

Creates a chart element that does not have an associated model yet. The association will be done later using the model key.

KDReports::Report::associateModel()

Definition at line 74 of file KDReportsChartElement.cpp.

References KDReports::modelForKey().

ChartElement() [3/4]

KDReports::ChartElement::ChartElement ( KDChart::Chart *  chart )

explicit

Creates a chart element from the given chart.

The chart's ownership is NOT transferred. It is very important that the chart exists at least as long as the report object exists.

Since

1.3

Definition at line 81 of file KDReportsChartElement.cpp.

~ChartElement()

KDReports::ChartElement::~ChartElement ( )

override

Destroys this chart element.

Definition at line 108 of file KDReportsChartElement.cpp.

ChartElement() [4/4]

KDReports::ChartElement::ChartElement

(

const ChartElement &

other

)

Copies a chart element.

build()

void KDReports::ChartElement::build ( ReportBuilder &  builder ) const

overridevirtual

clone()

operator=()

KDReports::ChartElement & KDReports::ChartElement::operator=

(

const ChartElement &

other

)

Copies the data from another chart element.

setChart()

void KDReports::ChartElement::setChart

(

KDChart::Chart *

chart

)

Sets the chart to use in this chart element. Useful for associating a chart to a ChartElement from XmlElementHandler.

The chart's ownership is NOT transferred. It is very important that the chart exists at least as long as the report object exists.

Since

1.3

Definition at line 110 of file KDReportsChartElement.cpp.

setModelKey()

void KDReports::ChartElement::setModelKey

(

const QString &

modelKey

)

set the model key associated with this element

Since

1.4

Definition at line 192 of file KDReportsChartElement.cpp.

References KDReports::modelForKey().

setSize()

void KDReports::ChartElement::setSize	(	qreal	width,
		qreal	height,
		Unit	unit = Millimeters
	)

Sets the size of the chart. The default size is a 100% of the page width, for both width and height.

To set a chart size that adapts well to any page size, use Percent as unit. setSize(50, 75, Percent) means that the width will be half of the page width (without margins), and the height will always be 1.5 times the width (preserving the ratio between 50 and 75). This feature (Percent) leads to slightly worse results on screen at 100% zoom, due to scaling happening even at that size, but the printed report should be fine.

setTableModel()

void KDReports::ChartElement::setTableModel

(

QAbstractItemModel *

tableModel

)

set the model associated with this element

Returns

the size of the chart, use unit() to know the size unit
