The controller for the graph. In the Model-View-Controller architecture, the controller is responsible for attending to user gestures, such as mouse clicks. This controller listens through Perspective For Java (PFJ) for user gestures. PFJ processes the information about the component that has been clicked.

Users of the graph bean normally do not need to call any of the methods of this class.

Constructor Detail

GraphControllerAdapter

public GraphControllerAdapter(Graph graph,
                              GraphModel graphModel)

Constructor. The graph constructs this object as part of its initialization.

Parameters:

graph - The graph that uses this Controller.

graphModel - The model that graph is using.

Method Detail

mousePressed

public void mousePressed(java.awt.event.MouseEvent e)

Specified by:

mousePressed in interface java.awt.event.MouseListener

Overrides:

mousePressed in class ControllerAdapter

Parameters:

e - event info

For internal use only. Application developers should not use this

Mouse pressed on view.

pivot

public void pivot(oracle.bali.ewt.pivot.PagingPivotEvent e)

A pivot move event happened

Specified by:

pivot in interface oracle.bali.ewt.pivot.PagingPivotListener

Parameters:

e - paging pivot event

swap

public void swap(oracle.bali.ewt.pivot.PagingPivotEvent e)

A pivot swap event happened

Specified by:

swap in interface oracle.bali.ewt.pivot.PagingPivotListener

Parameters:

e - paging pivot event

setCursor

protected void setCursor(java.awt.Component component,
                         java.awt.Cursor c)

setSelectedObject

public void setSelectedObject(ComponentHandle c)

Selects a component on the graph. The paging control calls this method.

Specified by:

setSelectedObject in interface GraphController

Parameters:

c - The component to select. For PFJ components, pass null.

getSelectedObject

public ComponentHandle getSelectedObject()

Retrieves the selected component. The paging control calls this method.

Specified by:

getSelectedObject in interface GraphController

Returns:

The selected component in a paging control, or null if the selected component is a PFJ component.

setCursorType

public void setCursorType(java.awt.Cursor c,
                          int type)

Specifies a cursor for a particular purpose. For example, this method specifies the cursor that appears when a user moves an object.

Specified by:

setCursorType in interface ViewController

Overrides:

setCursorType in class ViewControllerAdapter

Parameters:

c - The Cursor that should appear for type.

type - A constant that specifies the type of cursor that c is.

setWaitCursorForced

public void setWaitCursorForced(boolean yesNo)

Specifies whether the view is forced to display a wait cursor.

Specified by:

setWaitCursorForced in interface ViewController

Overrides:

setWaitCursorForced in class ViewControllerAdapter

Parameters:

yesNo - true to display the wait cursor. false do not display the wait cursor.

propertyChange
