Detailed Description

A QGLWidget that displays a Transfer Function Editor, or an Iso Selection Window.

Author: Alan Norton

Version: 3.0

Date: May 2015 The MappingFrame is a QGLWidget that can be used to map colors and/or opacity from a 1D interval. The MappingFrame can be inserted in the VAPOR tabs using QDesigner. Several Signal/Slot connections must be implemented to support editing functionality.

Member Function Documentation

void MappingFrame::endChange ( )

signal

Signal that is invoked when user ends modifying the transfer function. This should be connected to a slot in the EventRouter that completes and saves the Command that is used for saving the edit changes in the Command queue.

void MappingFrame::hookup	(	EventRouter *	evrouter,
		QPushButton *	editButton,
		QPushButton *	ZoomPan,
		QPushButton *	fitToView,
		QPushButton *	histoButton,
		QPushButton *	fitData,
		QPushButton *	bindColorToOpac,
		QPushButton *	bindOpacToColor,
		QSlider *	opacityScaleSlider
	)

Method required to establish a connection between the EventRouter that contains a transfer function editor, (or an IsoControl) and the MappingFrame that provides the editing functionality. This method should be invoked in the method EventRouter::hookupTab()

Parameters

[in]	evrouter	The EventRouter associated with this MappingFrame
[in]	editButton	The QPushButton that enables Edit mode
[in]	ZoomPan	QPushButton that enables zoom/pan (navigate) mode.
[in]	histoButton	QPushButton that refreshes the histogram.
[in]	fitData	QPushButton that fits the bounds to the data
[in]	bindColorToOpac	QPushButton that binds the selected color control point to selected opacity control point.
[in]	bindOpacToColor	QPushButton that binds the selected opacity control point to the selected color control point.
[in]	opacityScaleSlider	QSlider that controls the opacity scale

MapperFunction* MappingFrame::mapperFunction ( )

inline

Identify the current mapperFunction associated with the MappingFrame. Needed by various GLWidgets embedded in the MappingFrame

Returns: MapperFunction* associated with this MappingFrame.

Definition at line 172 of file mappingframe.h.

void MappingFrame::mappingChanged ( )

signal

Signal indicates that the mapping function has changed, update the visualizer on this signal if you want transfer function edits visualized in real-time

float MappingFrame::maxDataValue ( )

inline

Identify the maximum data value associated with the MappingFrame. Needed by various GLWidgets embedded in the MappingFrame

Returns: maximum data bound associated with this MappingFrame.

Definition at line 182 of file mappingframe.h.

float MappingFrame::minDataValue ( )

inline

Identify the minimum data value associated with the MappingFrame. Needed by various GLWidgets embedded in the MappingFrame

Returns: minimum data bound associated with this MappingFrame.

Definition at line 177 of file mappingframe.h.

void MappingFrame::setColorMapping ( bool flag )

Enable or disable the color mapping in the Transfer Function. Should be specified in the EventRouter constructor

Parameters

[in] flag set true if color mapping will be enabled.

void MappingFrame::setIsolineSliders ( bool flag )

inline

Enable or disable the use of multiple iso sliders in an IsoControl editor Should be specified in the EventRouter constructor

Parameters

[in] flag set true if multiple iso Sliders will be enabled.

Definition at line 141 of file mappingframe.h.

void MappingFrame::setIsolineSliders ( const vector< double > & slidervals )

Specify the set of values that will be associated with multiple Iso Sliders Should be specified whenever the Isovalues are changed.

Parameters

[in] slidervals is a vector of iso values

void MappingFrame::setIsoSlider ( bool flag )

inline

Enable or disable the use of a single iso slider in an IsoControl editor Should be specified in the EventRouter constructor

Parameters

[in] flag set true if one iso Slider will be enabled.

Definition at line 136 of file mappingframe.h.

void MappingFrame::setMapperFunction ( MapperFunction * mapper )

Specify the MapperFunction that is associated with this MappingFrame. This is invoked in EventRouter::setEditorDirty()

Parameters

[in] mapper MapperFunction to be associated with this MappingFrame

void MappingFrame::setOpacityMapping ( bool flag )

Enable or disable the opacity mapping in the Transfer Function. Should be specified in the EventRouter constructor

Parameters

[in] flag set true if opacity mapping will be enabled.

void MappingFrame::setVariableName ( std::string name )

Specify the variable associated with the MappingFrame. Invoked in EventRouter::setEditorDirty()

void MappingFrame::startChange ( QString description )

signal

Signal that is invoked when user starts to modify the transfer function. This should be connected to a slot in the EventRouter that creates a Command that will be used for putting the edit changes into the Command queue.

Parameters

[in] description of the change that is occurring

void MappingFrame::update ( )

inline

Update the display of the MappingFrame. Invoked in EventRouter::setEditorDirty()

Definition at line 165 of file mappingframe.h.

void MappingFrame::updateParams ( )

Synchronize the MappingFrame with the underlying RenderParams. Invoked in EventRouter::setEditorDirty().

void MappingFrame::updateTab ( RenderParams * rp )

Update the display of the Transfer Function or IsoControl based on the current RenderParams that contains the MapperFunction being used. This should be invoked in EventRouter::updateTab()

Parameters

[in] rp RenderParams* that contains the Transfer Function or IsoControl
