Inheritance diagram for GraphicsView:

Signals
void	signalContextMenuEvent (QString pointIdentifier)
	Send right click on axis point to MainWindow for editing.
void	signalDraggedDigFile (QString)
	Send dragged dig file to MainWindow for import. This comes from dragging an engauge dig file.
void	signalDraggedImage (QImage)
	Send dragged image to MainWindow for import. This typically comes from dragging a file.
void	signalDraggedImageUrl (QUrl)
	Send dragged url to MainWindow for import. This typically comes from dragging an image from a browser.
void	signalKeyPress (Qt::Key, bool atLeastOneSelectedItem)
	Send keypress to MainWindow for eventual processing by DigitizeStateAbstractBase subclasses.
void	signalLeave ()
	Send leave to MainWindow for managing the override cursor.
void	signalMouseMove (QPointF)
	Send mouse move to MainWindow for eventual display of cursor coordinates in StatusBar.
void	signalMousePress (QPointF)
	Send mouse press to MainWindow for creating one or more Points.
void	signalMouseRelease (QPointF)
	Send mouse release to MainWindow for moving Points.
void	signalViewZoomIn ()
	Send wheel event to MainWindow for zooming in.
void	signalViewZoomOut ()
	Send wheel event to MainWindow for zooming out.

Public Member Functions
	GraphicsView (QGraphicsScene *scene, MainWindow &mainWindow)
	Single constructor.
void	contextMenuEvent (QContextMenuEvent *event)
	Intercept right click to support point editing.
virtual void	dragEnterEvent (QDragEnterEvent *event)
	Intercept mouse drag event to support drag-and-drop.
virtual void	dragMoveEvent (QDragMoveEvent *event)
	Intercept mouse move event to support drag-and-drop.
virtual void	dropEvent (QDropEvent *event)
	Intercept mouse drop event to support drag-and-drop. This initiates asynchronous loading of the dragged image.
virtual void	keyPressEvent (QKeyEvent *event)
	Intercept key press events to handle left/right/up/down moving.
virtual void	leaveEvent (QEvent *event)
	Intercept leave events to manage override cursor.
virtual void	mouseMoveEvent (QMouseEvent *event)
	Intercept mouse move events to populate the current cursor position in StatusBar.
virtual void	mousePressEvent (QMouseEvent *event)
	Intercept mouse press events to create one or more Points.
virtual void	mouseReleaseEvent (QMouseEvent *event)
	Intercept mouse release events to move one or more Points.
virtual void	wheelEvent (QWheelEvent *event)
	Convert wheel events into zoom in/out.
