Class com.ibm.as400.vaccess.WorkingCursorAdapter

java.lang.Object
   |
   +----com.ibm.as400.vaccess.WorkingCursorAdapter

public class WorkingCursorAdapter
extends Object
implements WorkingListener, Serializable
The WorkingCursorAdapter class represents an object that listens for working events and sets the cursor as needed. When an event source starts working, the cursor is changed to the "wait" cursor. When an event source stops working, the cursor is changed back to the original cursor.

If multiple start events are fired, then the same number of stop events must be fired to get the cursor back to its original state.

The component property is used to determine the frame where the cursor is changed. If no component is set, or a parent frame is not available, then the cursor will not be changed.

The following example creates a tree model filled with the contents of a directory in the integrated file system of an AS/400. It will use a WorkingCursorAdapter object to change the cursor as needed.

// Set up the tree model in a JTree.
AS400TreeModel treeModel = new AS400TreeModel ();
JTree tree = new JTree (treeModel);

// Set up the working cursor adapter. treeModel.addWorkingListener (new WorkingCursorAdapter (tree));
// Set up the tree model to contain the contents of // a directory. AS400 system = new AS400 (); VIFSDirectory directory = new VIFSDirectory (system, "/myDirectory"); treeModel.setRoot (directory);
// Create a frame and add the tree. JFrame frame = new JFrame (); frame.getContentPane ().add (directory);


Constructor Index

 o WorkingCursorAdapter()
Constructs a WorkingCursorAdapter object.
 o WorkingCursorAdapter(Component)
Constructs a WorkingCursorAdapter object.

Method Index

 o getComponent()
Returns the component that determines the frame for cursor changes.
 o setComponent(Component)
Sets the component that determines the frame for cursor changes.
 o startWorking(WorkingEvent)
Processes a start working event.
 o stopWorking(WorkingEvent)
Processes a stop working event.

Constructors

 o WorkingCursorAdapter
 public WorkingCursorAdapter()
Constructs a WorkingCursorAdapter object.

 o WorkingCursorAdapter
 public WorkingCursorAdapter(Component component)
Constructs a WorkingCursorAdapter object.

Parameters:
component - The component.

Methods

 o getComponent
 public Component getComponent()
Returns the component that determines the frame for cursor changes.

Returns:
The component, or null if none has been set.
 o setComponent
 public void setComponent(Component component)
Sets the component that determines the frame for cursor changes.

Parameters:
component - The component.
 o startWorking
 public synchronized void startWorking(WorkingEvent event)
Processes a start working event. If the component has been added to a frame, then this will set the cursor to the wait cursor.

Parameters:
event - The event.
 o stopWorking
 public synchronized void stopWorking(WorkingEvent event)
Processes a stop working event. This will set the cursor back to its previous form. If there are, however, multiple calls to startWorking(), the cursor is not changed back until all starts have matching stops.

Parameters:
event - The event.
