Constructor Summary public   JGraphpadVertexTool(Object prototype)      Constructs a new vertex tool for the specified prototype using JGraphpadVertexTool.NAME_VERTEXTOOL . public   JGraphpadVertexTool(String name, Object prototype)      Constructs a new vertex tool for the specified name and prototype. Method Summary protected  Object createCell(GraphModel model)      Returns a deep clone of the cell prototype. Parameters:   model - The model to use for cloning the prototype. protected  void execute(JGraph graph, Object cell)      Provides a hook for subclassers to insert the specified cell into cache. public  Object getPrototype()      Returns the prototype used to create new cells. public  Dimension getSingleClickSize()      Returns the single click size which should be used to insert cells with a single click. public  int getThreshold()      Returns the threshold for a drag to count as an insert. protected  boolean isConstrainedSizeEvent(MouseEvent event)      Hook for subclassers to define the key assignments for constrained inserts. public  boolean isPreviewEnabled()      Sets if the cellview should be previewed. public  void mousePressed(MouseEvent event)      Extends the parent's implementation to create a clone of the pototype using JGraphpadVertexTool.createCell(GraphModel) and a new view using the layout cache's factory. public  void mouseReleased(MouseEvent event)      Overrides the parent's implementation to check if the event triggers an insert (checks JGraphpadVertexTool.threshold & JGraphpadVertexTool.singleClickSize ) and inserts the cell stored in JGraphpadVertexTool.previewView using JGraphpadVertexTool.execute(GraphLayoutCache,Object) . public  void overlay(JGraph graph, Graphics g, boolean clear)      Extends the parent's implementation to draw the JGraphpadVertexTool.previewView . protected  void processMouseDraggedEvent(MouseEvent event)      Overrides the parent's implementation to update the preview bounds to the current org.jgraph.graph.BasicMarqueeHandler.marqueeBounds . public  void setPreviewEnabled(boolean previewEnabled)      Returns if the cellview should be previewed. public  void setPrototype(Object prototype)      Sets the prototype to be used to create new cells. public  void setSingleClickSize(Dimension singleClickSize)      Sets the size of cells to be inserted with a single click. public  void setThreshold(int threshold)      Sets the threshold for a drag to count as an insert. Field Detail NAME_VERTEXTOOL final public static String NAME_VERTEXTOOL(Code) Defines the default name for tools of this kind. previewEnabled protected transient boolean previewEnabled(Code) Specifies if the cellview should be previewed. Default is true. previewView protected transient CellView previewView(Code) Preview vertex view. prototype protected Object prototype(Code) Holds the prototype to create new cells with. singleClickSize protected Dimension singleClickSize(Code) Defines the default size for vertices that are generated with a single click. A value of null ignores single clicks. Default is null. threshold protected int threshold(Code) Defines the threshhold (minimum size) for a drag to be used for an insert. Default is 4. Constructor Detail JGraphpadVertexTool public JGraphpadVertexTool(Object prototype)(Code) Constructs a new vertex tool for the specified prototype using JGraphpadVertexTool.NAME_VERTEXTOOL . Parameters:   prototype - The prototype cell to create new vertices with. JGraphpadVertexTool public JGraphpadVertexTool(String name, Object prototype)(Code) Constructs a new vertex tool for the specified name and prototype. Parameters:   name - The name of the tool to be created. Parameters:   prototype - The prototype cell to create new vertices with. Method Detail createCell protected Object createCell(GraphModel model)(Code) Returns a deep clone of the cell prototype. Parameters:   model - The model to use for cloning the prototype. Returns a clone of JGraphpadVertexTool.prototype. execute protected void execute(JGraph graph, Object cell)(Code) Provides a hook for subclassers to insert the specified cell into cache. This implementation passes the cell to the GraphLayoutCache.insert(Object) . Parameters:   cache - The cache into which to insert the edge. Parameters:   cell - The cell to be inserted into cache. getPrototype public Object getPrototype()(Code) Returns the prototype used to create new cells. Returns the prototype. getSingleClickSize public Dimension getSingleClickSize()(Code) Returns the single click size which should be used to insert cells with a single click. Returns the singleClickSize. getThreshold public int getThreshold()(Code) Returns the threshold for a drag to count as an insert. Returns the threshold. isConstrainedSizeEvent protected boolean isConstrainedSizeEvent(MouseEvent event)(Code) Hook for subclassers to define the key assignments for constrained inserts. This implementation redirects to BasicGraphUI.isConstrainedMoveEvent(MouseEvent) . Parameters:   event - The object that describes the event. isPreviewEnabled public boolean isPreviewEnabled()(Code) Sets if the cellview should be previewed. Returns the previewEnabled. mousePressed public void mousePressed(MouseEvent event)(Code) Extends the parent's implementation to create a clone of the pototype using JGraphpadVertexTool.createCell(GraphModel) and a new view using the layout cache's factory. The view is then configured and stored in JGraphpadVertexTool.previewView . Parameters:   event - The object that describes the event. mouseReleased public void mouseReleased(MouseEvent event)(Code) Overrides the parent's implementation to check if the event triggers an insert (checks JGraphpadVertexTool.threshold & JGraphpadVertexTool.singleClickSize ) and inserts the cell stored in JGraphpadVertexTool.previewView using JGraphpadVertexTool.execute(GraphLayoutCache,Object) . Parameters:   event - The object that describes the event. overlay public void overlay(JGraph graph, Graphics g, boolean clear)(Code) Extends the parent's implementation to draw the JGraphpadVertexTool.previewView . Parameters:   graph - The graph to paint in. Parameters:   g - The graphics to use for paiting. Parameters:   clear - Wether to clear the display. processMouseDraggedEvent protected void processMouseDraggedEvent(MouseEvent event)(Code) Overrides the parent's implementation to update the preview bounds to the current org.jgraph.graph.BasicMarqueeHandler.marqueeBounds . Parameters:   event - The object that describes the event. setPreviewEnabled public void setPreviewEnabled(boolean previewEnabled)(Code) Returns if the cellview should be previewed. Parameters:   previewEnabled - The previewEnabled to set. setPrototype public void setPrototype(Object prototype)(Code) Sets the prototype to be used to create new cells. Parameters:   prototype - The prototype to set. setSingleClickSize public void setSingleClickSize(Dimension singleClickSize)(Code) Sets the size of cells to be inserted with a single click. Parameters:   singleClickSize - The singleClickSize to set. setThreshold public void setThreshold(int threshold)(Code) Sets the threshold for a drag to count as an insert. Parameters:   threshold - The threshold to set.
