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.

References p_cubeHist, and p_stretch.

Member Function Documentation

◆ createStretchTable()

QTableWidget * Isis::StretchType::createStretchTable ( )
protected

This creates the stretch pairs table.

Returns
QTableWidget*

◆ deleteFromCube

void Isis::StretchType::deleteFromCube ( )
signal

◆ getStretch()

CubeStretch Isis::StretchType::getStretch ( )
virtual

Returns the current stretch object.

Returns
Stretch

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

◆ loadStretch

void Isis::StretchType::loadStretch ( )
signal

◆ 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, Isis::HistogramWidget::setHistogram(), and setStretch().

◆ 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().

◆ stretchChanged

◆ updateGraph

void Isis::StretchType::updateGraph ( )
protectedslot

This updates the graph with the current stretch object.
