Interface VisualGraphView

All Superinterfaces:: BaseCompositeContainer, CompositeNavigatorProvider, CompositeView, InteractionProvider, LayoutableGraph, Observable, VisualGraph, VisualGraphObjectContainer

public interface VisualGraphView
extends VisualGraph, CompositeView

This interface defines a view of a Graph model as well but adds additional functional specifications. Implementations of class VisualGraphView represent the top-level containers within a hierarchy of nested VisualGraphObjectContainer instances and are responsible for the undo, redo, cut, copy and paste functionalities within a graph document.

Constructing a VisualGraphView and other visual objects is done by means of a GraphViewFactory, which will hide the particular implementation classes from client code.

When new visual edges are introduced via edge-splitting, either manually or by user interaction, these new edges will be assigned a default style. This style can be configured for the entire view hierarchy by invoking the setDefaultEdgeStyle(String) method.

The paste orientation specifies how pasting preserves the relative order of connected VisualNode objects. See method setPasteOrientation(int).

VisualEdge update modes determine how connected VisualEdge objects should behave when the position of a VisualNode changes. Update modes can be set with method setVisualEdgeUpdateMode(int).

A VisualGraphView supports user interaction with the mouse. To do so it provides the methods listed below:

For both cut() and copy() operations, the currently selected items are copied onto the clipboard, overriding its previous content. The cut() method can be thought of as a copy() operation that is succeeded by a deletion of the selected items. Since it is possible to select both parent containers and their children simultaneously, an internal logic will skip clipboard processing for all selected elements whose parents are selected as well. This is necessary to prevent unexpected results.

Upon invocation of the paste() method, the clipboard contents are copied again and the resulting copies are inserted into the VisualGraphView or nested VisualSubgraph objects. This additional copy is required since it is possible to paste the same clipboard contents multiple times.

Not including the special paste() methods discussed in the next section, the following events happen when a normal paste() method is invoked. Please note that there are two paste() methods, one accepting no parameters and one of which takes an argument of type Coordinate that specifies a geometric reference point for the paste() operation.

If reference coordinates are given (typically mouse coordinates), then the following happens: (This means the version of paste that takes a Coordinate instance as an argument was invoked.)

If the mouse is positioned within the region of a VisualSubGraph, then the clipboard contents are pasted at the mouse position as children of the particular VisualSubGraph.
If the mouse is not positioned within the region of a VisualSubGraph, then the clipboard contents are pasted at the mouse position in the top-level VisualGraphView.

If no reference coordinates are given, then the following happens: (This means the no-argument version of paste() was invoked.)

If exactly one element is selected in the entire hierarchy of the destination VisualGraphView and this element is not of type VisualSubGraph, then the bounding box of the clipboard' contents is positioned at the position of the selected element plus an additional offset. If all inserted items are invisible, the visible region of the VisualGraphView is translated so that the center of the bounding box of the clipboards contents is positioned at the center of the visible region.
If exactly one element is selected in the entire hierarchy of the destination VisualGraphView and this element is of type VisualSubGraph, then a region R is determined by intersecting the visible region and the boundary of the selected VisualSubGraph. If the region R is not empty, then the bounding box of the clipboards contents is positioned at the center of R. If R is the empty region, then the contents of the clipboard are positioned so that the bounding box is centered at the selected VisualSubGraph. Afterwards, the center of the visible region is moved so that it is positioned on top of the bounding box of the clipboards contents.
If multiple items are selected or no item is selected at all, the clipboards contents are inserted into the top-level VisualGraphView instance at the center of the visible region.

For enabling and disabling buttons and menu items in a GUI, it is necessary to programatically determine if anything is currently available from the clipboard. The getClipboardSize() method provides exactly this functionality. If the returned size is larger than zero, you should enable the paste button and/or menu item.

The methods setSelectPastedElements(boolean) and isSelectPastedElements() are used for setting and getting that property of the VisualGraphView which determines whether pasted items are to be selected after the operation or not.

The methods getPasteOrientation() and setPasteOrientation(int) are used for getting and setting the view orientation. Setting it specifies a sorting order when multiple nodes are inserted before or behind a reference node by means of the pasteBefore(com.tensegrity.graph.view.VisualNode) and pasteBehind(com.tensegrity.graph.view.VisualNode) methods. Also the methods pasteStart() and pasteStop() are dependent on this sorting order. If only the plain paste methods are used, it is not required to set this data.

VisualGraphView instances that are dereferenced will be garbage collected.

VisualGraphView derives from and thus aggregates many interfaces, including VisualGraph, CompositeView and the VisualGraphObjectContainer interfaces, allowing clients to treat a VisualGraphView as one of many specific roles.

Also, it is important to note that a new VisualGraphView instance requires a reference to a GraphController, which must be advised to manage the newly created view after instantiation.

Method Detail

destroy

public void destroy()

Destroys all resources and registered listener references.

WARNING: After invoking this method the VisualGraphView is left in an unusable way

Think of this method like a destructor in c++.

getDrawingOrder

public int getDrawingOrder()

Returns a constant that represents the current drawing order of the VisualGraphView.

Returns:: int the current drawing order
See Also:: DRAW_EDGES_FIRST, DRAW_NODES_FIRST

setDrawingOrder

public void setDrawingOrder(int drawingorder)

Sets the drawing order of the graph to the mode given by drawingorder. Valid modes are defined through constants in this interface.

Parameters:: drawingorder - the new drawing order of the graph
See Also:: DRAW_EDGES_FIRST, DRAW_NODES_FIRST

getGraphController

public GraphController getGraphController()

Returns the primary GraphController of this visualgraphview.

Returns:: the primary GraphController of this visualgraphview.

registerNestedVisualEdgeCreationController

public void registerNestedVisualEdgeCreationController(NestedVisualEdgeCreationController edgecreationcontroller)

Registers a NestedVisualEdgeCreationController. This controller instance serves as a callback to customize nested-visualedge creation (creation of visualedges that refer to visualnodes that are placed arbitrarily in the hierarchy of a single visualgraphview and nested visualsubgraphs).

Parameters:: edgecreationcontroller - the NestedVisualEdgeCreationController to register.

unregisterNestedVisualEdgeCreationController

public NestedVisualEdgeCreationController unregisterNestedVisualEdgeCreationController()

Unregisters the current NestedVisualEdgeCreationController. If none is currently registered, nothing will happen.

Returns:: the previously registered NestedVisualEdgeCreationController or null if none was registered.

setVisualEdgeUpdateMode

Sets the update-mode for VisualEdges. The update-mode determines the behavior of VisualEdges when any of the VisualNodes they are connected to are moved.

UPDATEMODE_SIMPLE
Update only fully connected VisualEdges. If a VisualEdge is not fully connected on both ends, then moving the VisualNode that has one end connected won't change any of the VisualEdges coordinates.
UPDATEMODE_PLAIN
Similar to update mode UPDATEMODE_SIMPLE, but it will also update objects of type VisualEdge that are connected to exactly one of the ends of the corresponding VisualNode.
UPDATEMODE_ORTHOGONAL
Keep care of orthogonal (parallel to x or y-axis) segments of the edge and distributes the changes horizontally and vertically to those segments, thus preserving orthogonality.

Parameters:: visualedgeUpdateMode - the update-mode to set for all VisualEdges embedded in this instance.
Find more information in the class documentation

splitEdge

public VisualEdge[] splitEdge(VisualEdge visualedge,
                              VisualNode visualnode)

Splits the given VisualEdge with the given VisualNode.

Both the given VisualEdge and the given VisualNode must be contained in this VisualGraphView or in an instance of VisualSubgraph that is nested directly or indirectly within this VisualGraphView instance.

If the VisualEdge and the VisualNode are not in the same VisualSubgraph (or respectively VisualGraphObjectContainer) the VisualNode is moved across the hierarchy into the VisualGraphObjectContainer of the VisualEdge to be split. If a veto occurs before the split, then the cross VisualGraphObjectContainer-move is undone.

This method takes care of the rule setting of the EdgeRule associated to the given VisualEdge and the NodeRule associated to the given VisualNode. If one of the two rules prohibits the split operation it is not performed. One can overcome this behaviour by either changing the rule setting or by using the RuleConfiguration associated to this VisualGraphView.

Parameters:: visualedge - the VisualEdge to split; visualnode - the VisualNode to split the VisualEdge with
Returns:: an array of length two that contains the new edges, that originate from the splitting process. The array may contain two null pointers if and only if the edge split was veto'd by a rule setting or a VetoableGraphEventMediatorListener or a VetoableGraphListener.

createCrossVisualEdge

public VisualEdge createCrossVisualEdge(VisualNode sourcenode,
                                        VisualNode targetnode)

Adds a cross edge between two given VisualNodes. The two specified VisualNodes can be in different VisualGraphObjectContainers across the same hierarchy. If the two specified VisualNodes are currently in the same nested hierarchy of VisualGraphObjectContainers or even in exactly the same VisualGraphObjectContainer, then a VisualEdge is created between the specified nodes. A model edge is also created and before. The main benefit compared to adding a VisualEdge another way, is that the functionality for finding the correct VisualGraphObjectContainer for the desired edge. The target VisualGraphObjectContainer is found by traversing up the nesting hierarchy of the edge's start and end until a common predecessor VisualGraphObjectContainer is identified. The newly introduced VisualEdge is thus not isolated and associated with a corresponding object within the model scope.

The following invariants must be true for this method:

The VisualNode references point to non-null and currently added VisualNode instances, which are share a common top level VisualGraphView in their hierarchy of ancestors. It is the responsibility of the method's client to make sure these conditions are met.
After the algorithm has determined the desired VisualEdge and its start and end, there will be a check whether the new edge would result in a multi-edge. If that is the case it is checked whether multe-edges are allowed by the model or not.

There are several reasons why the creation of a nested edge might fail. One possibility is that the edges are not in the same VisualGraph hierarchy. Another reason is that the exact same edge might exist in the hierarchy already. In either case null is returned.

Parameters:: sourcenode - the source VisualNode for the VisualEdge that should be created.; targetnode - the target VisualNode for the VisualEdge that should be created.
Returns:: the VisualEdge which was created or null if none was created.

createCrossVisualEdge

public VisualEdge createCrossVisualEdge(VisualEdge visualedge,

enableVetosWithStack

public void enableVetosWithStack(boolean enable)

This method is API internal and should not be invoked by clients.

Depending on the given boolean this method enables or disables all vetoable events for this VisualGraphView object and nested VisualSubgraph objects as well.
Additionally the old state is put onto a stack so that it can be easily restored afterwards.
Notice:When setting the state through this method one must call the method enableVetosFromStack() afterwards. Otherwise the internal stack gets demaged.

Parameters:: enable - flag indicating whether to raise vetoable events
See Also:: enableVetosFromStack()

enableVetosFromStack
