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.

History:
2011-11-04 Steven Lambright - Split up updateGraph and updateTable and moved them to protected. The manual stretch type needs to choose explicitly when to update the table, but always wants to update the graph.

Constructor & Destructor Documentation

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

Definition at line 30 of file StretchType.cpp.

Isis::StretchType::~StretchType ( )
virtual

Destructor.

Member Function Documentation

QTableWidget * Isis::StretchType::createStretchTable ( )

Stretch Isis::StretchType::getStretch ( )
virtual

Returns the current stretch object.

Returns
Stretch

void Isis::StretchType::savePairs ( )

This asks the user for a file and saves the current stretch pairs to that file.

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

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