Field Detail

DEFAULT_MAX_HANDLERS

public static int DEFAULT_MAX_HANDLERS

Defines the default value for maxHandlers. Default is 100.

graphComponent

protected mxGraphComponent graphComponent

Reference to the enclosing graph component.

enabled

protected boolean enabled

Specifies if this handler is enabled.

visible

protected boolean visible

Specifies if this handler is visible.

bounds

protected Rectangle bounds

Reference to the enclosing graph component.

maxHandlers

protected int maxHandlers

Defines the maximum number of handlers to paint individually. Default is DEFAULT_MAX_HANDLES.

handlers

protected transient LinkedHashMap<Object,mxCellHandler> handlers

Maps from cells to handlers in the order of the selection cells.

refreshHandler

protected transient mxEventSource.mxIEventListener refreshHandler

labelMoveHandler

protected transient PropertyChangeListener labelMoveHandler

Constructor Detail

mxSelectionCellsHandler

public mxSelectionCellsHandler(mxGraphComponent graphComponent)

Parameters:

graphComponent -

Method Detail

addGraphListeners

protected void addGraphListeners(mxGraph graph)

Installs the listeners to update the handles after any changes.

removeGraphListeners

protected void removeGraphListeners(mxGraph graph)

Removes all installed listeners.

getGraphComponent

public mxGraphComponent getGraphComponent()

isEnabled

public boolean isEnabled()

setEnabled

public void setEnabled(boolean value)

isVisible

public boolean isVisible()

setVisible

public void setVisible(boolean value)

getMaxHandlers

public int getMaxHandlers()

setMaxHandlers

public void setMaxHandlers(int value)

getHandler

public mxCellHandler getHandler(Object cell)

mousePressed

public void mousePressed(MouseEvent e)

Dispatches the mousepressed event to the subhandles. This is called from the connection handler as subhandles have precedence over the connection handler.

Specified by:

mousePressed in interface MouseListener

mouseMoved

public void mouseMoved(MouseEvent e)

Specified by:

mouseMoved in interface MouseMotionListener

mouseDragged

public void mouseDragged(MouseEvent e)

Specified by:

mouseDragged in interface MouseMotionListener

mouseReleased

public void mouseReleased(MouseEvent e)

Specified by:

mouseReleased in interface MouseListener

getToolTipText

public String getToolTipText(MouseEvent e)

Redirects the tooltip handling of the JComponent to the graph component, which in turn may use getHandleToolTipText in this class to find a tooltip associated with a handle.

reset

public void reset()

refresh

public void refresh()

paintHandles

public void paintHandles(Graphics g)

mouseClicked

public void mouseClicked(MouseEvent arg0)

Specified by:

mouseClicked in interface MouseListener

mouseEntered

public void mouseEntered(MouseEvent arg0)

Specified by:

mouseEntered in interface MouseListener

mouseExited

public void mouseExited(MouseEvent arg0)

Specified by:

mouseExited in interface MouseListener
