Field Detail

NO_EVENT_POLICY

public static final samples.preview_new_graphdraw.impl.GraphLayoutPanelMouseListener.ClickPolicy NO_EVENT_POLICY

No graph events are fired from this panel

VERTEX_ONLY_POLICY

public static final samples.preview_new_graphdraw.impl.GraphLayoutPanelMouseListener.ClickPolicy VERTEX_ONLY_POLICY

Only vertex events are fired from this panel. If a click isn't near a vertex, no events are fired.

EDGE_ONLY_POLICY

public static final samples.preview_new_graphdraw.impl.GraphLayoutPanelMouseListener.ClickPolicy EDGE_ONLY_POLICY

Only edge events are fired from this panel. If a click isn't near a edge, no events are fired.

EDGE_AND_VERTEX_POLICY

public static final samples.preview_new_graphdraw.impl.GraphLayoutPanelMouseListener.ClickPolicy EDGE_AND_VERTEX_POLICY

Either an edge event or a vertex event is fired from this panel. If the click is close to a vertex, a vertex event is fired; otherwise, if the click is close to an edge, the edge event.

EDGE_AND_VERTEX_BOTH

public static final samples.preview_new_graphdraw.impl.GraphLayoutPanelMouseListener.ClickPolicy EDGE_AND_VERTEX_BOTH

Both an edge event or a vertex event is fired from this panel. If the click is close to a vertex, a vertex event is fired; if the click is close to an edge, the edge event. (If both, then both may be fired: it is up to the developer to choose a mechansim. For example, some applications will select only vertices if the user is holding down the control button.)

Constructor Detail

GraphLayoutPanel

public GraphLayoutPanel(Graph g,
                        Dimension d,
                        VertexRenderer vr,
                        EdgeRenderer er)

Creates a GraphLayout panel. It will set its preferred size to d, its local graph to g

Parameters:

g -

d -

vr -

er -

Method Detail

getDefaultMouseListener

protected MouseListener getDefaultMouseListener()

By default, returns a JunGraphPanelMouseListener. Override this to install your own MouseListener instead of the one provided. (You can always add another listener with affecting this one.)

paintComponent

protected void paintComponent(Graphics graphics)

This method paints the component. It does so by calling renderEdge and renderVertex on every VERTEX and every EDGE in the CURRENT GRAPH. Note that this will crash if the current graph has mutated.

Overrides:

paintComponent in class JComponent

See Also:

JComponent.paintComponent(java.awt.Graphics)

addClickListener

public void addClickListener(ClickListener cl)

setClickPolicy

public void setClickPolicy(samples.preview_new_graphdraw.impl.GraphLayoutPanelMouseListener.ClickPolicy policy)

getGraphLayout

public EmittedLayout getGraphLayout()

(Called only by vertexdrag.)

setLayoutDisplay

public void setLayoutDisplay(EmittedLayout lr2)

We maintain, in memory, two layouts. One of them is the one currently being drawn. It's been distorted, warped, and bumped through the pipeline. The other is a clean original.

Parameters:

lr2 -

getPipeline

public TransformerPipeline getPipeline()

resizeLayouts

public void resizeLayouts()

updateGraphToMatch

public void updateGraphToMatch(Graph g)

Parameters:

g -
