public interface LayoutEngine
This interface class has been added to facilitate the addition of other layout engines to this package. Any class that wants to lay out a graph should implement this interface.
Method Summary | |
---|---|
void |
addLayoutCompleteEventListener(LayoutCompleteEventListener e)
This method adds a LayoutCompleteEventListener to the LayoutEngine. |
void |
fireLayoutCompleteEvent(LayoutCompleteEvent e)
This fires a LayoutCompleteEvent once a layout has been completed. |
javax.swing.JPanel |
getControlPanel()
This method returns the extra controls panel for the LayoutEngine, if there is any. |
FastVector |
getNodes()
give access to set of graph nodes |
javax.swing.JProgressBar |
getProgressBar()
This method returns the progress bar for the LayoutEngine, which shows the progress of the layout process, if it takes a while to layout the graph |
void |
layoutGraph()
This method lays out the graph for better visualization |
void |
removeLayoutCompleteEventListener(LayoutCompleteEventListener e)
This method removes a LayoutCompleteEventListener from the LayoutEngine. |
void |
setNodesEdges(FastVector nodes,
FastVector edges)
This method sets the nodes and edges vectors of the LayoutEngine |
void |
setNodeSize(int nodeWidth,
