Detailed Description

This widget encompasses the entire matrixDisplay scene.

This widget is a self-contained view of the correlation matrix resulting from a bundle adjust. It uses Qt's graphics scene/view framework. This widget holds the graphics scene, view, and items. It will also hold the options dialog for the matrix.

Constructor & Destructor Documentation

◆ MatrixSceneWidget()

Isis::MatrixSceneWidget::MatrixSceneWidget ( QStatusBar * status,
bool showTools,
bool internalizeToolBarsAndProgress,
Directory * directory,
QWidget * parent = 0 )

Constructor, creates a matrix scene widget.

Parameters
statusPointer to an existing status bar
showToolsWhether or not create a matrix scene or matrix world view
internalizeToolBarsAndProgressWhether or not to show progress and status
directoryThe directory of the current project
parentQPointer to the parent widget

◆ ~MatrixSceneWidget()

Isis::MatrixSceneWidget::~MatrixSceneWidget ( )
virtual

Default Destructor.

Member Function Documentation

◆ contextMenuEvent()

bool Isis::MatrixSceneWidget::contextMenuEvent ( QGraphicsSceneContextMenuEvent * event)

This is called by MatrixGraphicsScene::contextMenuEvent.

Parameters
eventThe context menu event
Returns
bool false if not handled, true if handled.

References getScene().

◆ directory()

Directory * Isis::MatrixSceneWidget::directory ( ) const

Accessor for the directory.

Returns
Directory* The directory

◆ drawElements()

void Isis::MatrixSceneWidget::drawElements ( CorrelationMatrix corrMatrix)

Draw elements.

If element is drawn in black, something is wrong. The correlation value is out of range.

Need separate redraw method because we will already have the list of MatrixSceneItems.

Parameters
corrMatrixThe matrix that belongs to the project.

◆ drawGrid()

void Isis::MatrixSceneWidget::drawGrid ( CorrelationMatrix corrMatrix)

Draw the lines that will show the columns and blocks for each image.

Parameters
corrMatrixThe matrix that belongs to the project

◆ elementClicked

void Isis::MatrixSceneWidget::elementClicked ( QString )
signal

Emitted when an element of the widget is clicked.

◆ eventFilter()

bool Isis::MatrixSceneWidget::eventFilter ( QObject * obj,
