Detailed Description

This is the base class for advanced stretches.

This has the common functionality between the advanced stretch types. It provides a histogram, the stretch table, and layouts. It also stores the stretch pairs. Using this should keep all of the advanced stretch interfaces similar and uniformly accessible from the stretch tool.

Constructor & Destructor Documentation

StretchType()

Isis::StretchType::StretchType	(	const Histogram &	hist,
		const Stretch &	stretch,
		const QString &	name,
		const QColor &	color )

This constructs a stretch type.

It provides a main layout, sizing policies, and a few widgets. Children should insert themselves at the main layout grid row 1 column 0.

Parameters

hist
stretch
name
color

~StretchType()

Isis::StretchType::~StretchType ( )

virtual

Destructor.

Member Function Documentation

createStretchTable()

QTableWidget * Isis::StretchType::createStretchTable ( )

protected

This creates the stretch pairs table.

Returns

QTableWidget*

Referenced by StretchType().

deleteFromCube

void Isis::StretchType::deleteFromCube ( )

signal

Referenced by StretchType().

getStretch()

CubeStretch Isis::StretchType::getStretch ( )

virtual

Returns the current stretch object.

Returns

Stretch

Reimplemented in Isis::BinaryStretchType, Isis::LinearStretchType, Isis::ManualStretchType, and Isis::SawtoothStretchType.

References p_stretch.

Referenced by updateTable().

loadStretch

void Isis::StretchType::loadStretch ( )

signal

Referenced by StretchType().

saveToCube

void Isis::StretchType::saveToCube ( )

signal

Emitted when a new Stretch object is available.

Referenced by StretchType().

setHistogram()

void Isis::StretchType::setHistogram ( const Histogram & hist )

virtual

This should be called when the visible area changes.

It updates the graph and calls setStretch() so that the children have a chance to update their GUI elements too.

Parameters

hist

References p_cubeHist, p_graph, p_stretch, and setStretch().

Referenced by Isis::AdvancedStretch::setHistogram().

setStretch()

virtual void Isis::StretchType::setStretch ( Stretch )

pure virtual

Children must re-implement this to update their stretch pairs and GUI elements appropriately.

This could be called with a different histogram but not a different stretch.

Implemented in Isis::BinaryStretchType, Isis::LinearStretchType, Isis::ManualStretchType, and Isis::SawtoothStretchType.

Referenced by setHistogram(), and Isis::AdvancedStretch::setStretch().

stretchChanged

void Isis::StretchType::stretchChanged ( )

signal

updateGraph

void Isis::StretchType::updateGraph ( )

protectedslot

This updates the graph with the current stretch object.

References p_graph, and p_stretch.

Referenced by StretchType().

updateTable

void Isis::StretchType::updateTable ( )

protectedslot

This updates the table with the current stretch pairs.

References getStretch(), Isis::Stretch::Input(), Isis::Stretch::Output(), p_table, and Isis::Stretch::Pairs().
