Class TraceController

java.lang.Object

diva.compat.trace.TraceController

public class TraceController
extends Object

A controller for trace diagrams. This controller sets up all the interaction on the pane, and creates interactors and other objects that control how the surface responds to user interaction. Currently, the degree of parameterization is limited, but this will be increased in future.

TraceController

public TraceController()

Create a new controller

TraceController

public TraceController(GraphicsPane pane)

Create a new controller for the given pane

Method Detail

getDragInteractor

public DragInteractor getDragInteractor()

Get the drag interactor

getTraceModel

public final TraceModel getTraceModel()

Get the trace model.

getTraceView

public final TraceView getTraceView()

Get the trace view.

getSelectionDragger

public SelectionDragger getSelectionDragger()

Get the selection interactor

getSelectionRenderer

public SelectionRenderer getSelectionRenderer()

Get the selection renderer

getSelectionInteractor

public SelectionInteractor getSelectionInteractor()

Get the selection interactor

initializeInteraction

public void initializeInteraction()

Initialize all interaction on the trace pane. By the time this method is called, all relevant references to views, panes, and interactors must already have been set up.

setTraceModel

public void setTraceModel(TraceModel m)

Set the trace model that is being viewed. Unsubscribe from the previous one if there is one. Then subscribe to the new one.

setTraceView

public void setTraceView(TraceView view)

Set the view that this controller operates on. This method sets the view, and calls initializeInteraction().

setSelectionManipulator

public void setSelectionManipulator(Manipulator manipulator)

Set the prototype selection manipulator. Selected figures will have a copy of this manipulator wrapped around them. This method nullifies any previous renderers set with setSelectionRenderer();

setSelectionRenderer

public void setSelectionRenderer(SelectionRenderer renderer)

Set the selection renderer. Selected figures will be highlighted with this renderer.
