Member Function Documentation

virtual QRectF vtkQtChartAxisLayer::boundingRect

(

)

const [virtual]

void vtkQtChartAxisLayer::cancelChartRangeChange

(

)

[slot]

Clears the flag to gather the chart domains during layout.

vtkQtChartAxis* vtkQtChartAxisLayer::getAxis

(

vtkQtChartAxis::AxisLocation

location )

const

Gets the axis in the specified location.

Parameters:

location

The location of the axis.

Returns:

A pointer to the specified axis.

Referenced by QmitkVtkHistogramWidget::QmitkVtkHistogramWidget(), and QmitkVtkLineProfileWidget::QmitkVtkLineProfileWidget().

AxisBehavior vtkQtChartAxisLayer::getAxisBehavior

(

vtkQtChartAxis::AxisLocation

location )

const

Gets the layout behavior for the specified axis.

Parameters:

location

The location of the axis.

Returns:

The layout behavior for the specified axis.

const vtkQtChartAxisDomainPriority& vtkQtChartAxisLayer::getAxisDomainPriority

(

vtkQtChartAxis::AxisLocation

location )

const

Gets the domain priority order for the given axis.

Parameters:

location

The location of the axis.

Returns:

A reference to the domain priority order.

vtkQtChartAxis* vtkQtChartAxisLayer::getHorizontalAxis

(

vtkQtChartLayer::AxesCorner

axes )

const

Gets the horizontal axis in the specified pair.

Parameters:

axes	The pair of chart axes.

Returns:

A pointer to the specified axis.

QRectF vtkQtChartAxisLayer::getLayerBounds

(

)

const [inline]

Gets the area inside the chart axes.

Returns:

The area inside the chart axes.

Definition at line 138 of file vtkQtChartAxisLayer.h.

{return this->LayerBounds;}

vtkQtChartAxis* vtkQtChartAxisLayer::getVerticalAxis

(

vtkQtChartLayer::AxesCorner

axes )

const

Gets the vertical axis in the specified pair.

Parameters:

axes	The pair of chart axes.

Returns:

A pointer to the specified axis.

void vtkQtChartAxisLayer::handleChartRangeChange

(

)

[slot]

Sets a flag to gather the chart domains during layout.

virtual void vtkQtChartAxisLayer::layoutChart

(

const QRectF &

area )

[virtual]

Used to layout the chart axes.

The area passed to this method is the total chart area. The axis layer uses the whole area to layout the axes. Once the layout is complete, the space inside the axes is passed to the other chart layers.

Parameters:

area	The area the axes should occupy.

See also:

vtkQtChartAxisLayer::getLayerBounds()

Implements vtkQtChartLayer.

virtual void vtkQtChartAxisLayer::paint	(	QPainter *	painter,
		const QStyleOptionGraphicsItem *	option,
		QWidget *	widget = 0
	)		[virtual]

void vtkQtChartAxisLayer::setAxisBehavior	(	vtkQtChartAxis::AxisLocation	location,
		AxisBehavior	behavior
	)

Sets the layout behavior for the specified axis.

Parameters:

location	The location of the axis.
behavior	The new layout behavior.

void vtkQtChartAxisLayer::setAxisDomainPriority	(	vtkQtChartAxis::AxisLocation	location,
		const vtkQtChartAxisDomainPriority &	priority
	)

Sets the domain priority order for the given axis.

Parameters:

location	The location of the axis.
priority	The new domain priority order.

virtual void vtkQtChartAxisLayer::setChartArea

(

vtkQtChartArea *

area )

[virtual]

Sets the chart area that contains this layer.

The contents space object for the axes is set to the one used by the chart area.

Parameters:

area	The new chart area.

Reimplemented from vtkQtChartLayer.
