所有已实现的接口:

Serializable

public class BPDGraphUI
extends org.jgraph.plaf.basic.BasicGraphUI

This class and it's inner classes controls mouse actions and clipboard. It is adapted to get wanted editing cell behaviour, selection behaviour , to implement cell overlaping, to implement right participant adjustment after cell (or group of cells) is moved, and to implement proper copying and pasting/cloning of cells, as well as pasting at wanted location (along with right participant adjustment).

canMouseReleaseSelectCell

protected boolean canMouseReleaseSelectCell

Variable that correct selection on mouse release.

insertionPoint

protected Point insertionPoint

Point that represents paste location. It is set from editor when PasteAt action was triggered by popup menubar.

构造器详细资料

BPDGraphUI

public BPDGraphUI()

方法详细资料

getGraph

public AbstractGraph getGraph()

Returns graph.

setInsertionPoint

public void setInsertionPoint(Point p)

Sets location for pasting cells.

startEditingAtCell

public void startEditingAtCell(org.jgraph.JGraph graph,
                               Object cell)

覆盖:

startEditingAtCell 在类中 org.jgraph.plaf.basic.BasicGraphUI

paintBackground

protected void paintBackground(Graphics g)

Paint the background of this graph. Calls paintGrid.

覆盖:

paintBackground 在类中 org.jgraph.plaf.basic.BasicGraphUI

startEditing

protected boolean startEditing(Object cell,
                               MouseEvent event)

This method is called by EditAction class, as well as by pressing F2 or clicking a mouse on a cell.

覆盖:

startEditing 在类中 org.jgraph.plaf.basic.BasicGraphUI

createMouseListener

protected MouseListener createMouseListener()

Creates the listener responsible for updating the selection based on mouse events.

覆盖:

createMouseListener 在类中 org.jgraph.plaf.basic.BasicGraphUI

createHandle

public org.jgraph.graph.CellHandle createHandle(org.jgraph.graph.GraphContext context)

Constructs the "root handle" for context.

覆盖:

createHandle 在类中 org.jgraph.plaf.basic.BasicGraphUI

参数:

context - reference to the context of the current selection.

createGraphViewObserver

protected Observer createGraphViewObserver()

Returns a listener that can update the graph when the model changes.

覆盖:

createGraphViewObserver 在类中 org.jgraph.plaf.basic.BasicGraphUI

createTransferHandler

protected TransferHandler createTransferHandler()

Creates an instance of TransferHandler. Used for subclassers to provide different TransferHandler.

覆盖:

createTransferHandler 在类中 org.jgraph.plaf.basic.BasicGraphUI

insertCells

public void insertCells(Object[] cells,
                        Map viewAttributeMap,
                        org.jgraph.graph.ConnectionSet cs,
                        boolean clone,
                        int dx,
                        int dy)

Insert the specified cells into the model. If clone is true, the cells are cloned an all datastructures are updated to reference these clones. Clones are created using the GraphModel.clone(Object)-method. If cells are cloned, they are translated using the given amount. This method is modified from original to support pasteAt action, and to forbid pasting of Participants, Subflows and Transitions as well as to fix a bug which didn't clone cell's userObject properly.
