A manager view is a Java AWT component used to display the graphic objects contained in a manager.
Overview

A manager view is attached to a single manager at a time. However, each manager can be connected to several views simultaneously. The manager to which a view is attached is defined when you call the constructor; you retrieve and change this manager by calling setManager(IlvManager) and getManager().

Zooming and Transformation

Each manager view contains a geometric transformer which defines the translation, the scaling and the rotation applied to the drawing of the graphic objects in the manager attached to this view. A transformer is defined by an IlvTransformer instance.

You modify the transformations associated with a view either by calling setTransformer(IlvTransformer) or getTransformer() to change the transformer, or by calling methods that change the transformer for you. Examples of this are zoom(IlvPoint, double, double, boolean), translate(double, double, boolean), fitTransformerToContent().

When KeepingAspectRatio is true, the view will verify each modification of its transformer so that the zoom factor remains the same along the x axis and the y axis. The zoom level can be different on the x axis and on the y axis, for instance in order to fit the content into a area of a given aspect ratio. If you need to ensure the zoom level remains always the same along the two axis, use the the method setKeepingAspectRatio(boolean).

Example

The following code example shows how to use two manager view instances to display a manager in different ways.
```
  IlvGraphic obj;
  IlvManager manager = new IlvManager();
      
  // Create new graphic objects and add them to the submanager.
  // These graphic objects will be beneath the other objects.
  obj = new IlvEllipse(new IlvRect(30, 10, 50, 50), true, false);
  manager.addObject(obj, false);
  
  // Add a new graphic object to layer 2 in the manager
  obj = new IlvRectangle(new IlvRect(70,40,50,50), false, true);
  manager.addObject(obj, 2, false);
  
  // Add the manager to different views.
  IlvManagerView viewOne = new IlvManagerView(manager);
  IlvManagerView viewTwo = new IlvManagerView(manager);
  viewOne.setBackground(Color.RED);
  viewTwo.setBackground(Color.GREEN);
  // Add a grid to viewOne
  viewOne.setGrid(new IlvGrid());
  // Zoom into viewTwo
  viewTwo.zoom(new IlvPoint(50,70), 2, 2, true);
  // Set all the graphic objects in layer 2 to be invisible 
  // for viewOne.
  manager.setVisible(viewOne, 2, false, true);
  
  JFrame frame = new JFrame("IlvManagerView");
  frame.setLayout(new BorderLayout(2, 2));
  JSplitPane splitPane = new JSplitPane(
    JSplitPane.HORIZONTAL_SPLIT, viewOne, viewTwo);
  splitPane.setDividerLocation(140);
  frame.getContentPane().add(splitPane);
  frame.setSize(320, 200);
  frame.setVisible(true);
 
```
The following image shows the two views created for a single manager in the code example:

Translucency

A manager view is opaque by default, that is, it paints all pixels of its assigned bounds without transpacency. In the opposite case, that is, when the components behind the view partially shine through, it is called translucent. A manager view can be made translucent in three ways:
- A partially transparent background image can be installed, through the method setBackgroundPattern(Image) or setBackgroundPatternLocation(URL).
- A translucent color can be installed as a background color, through the method setBackground(Color).
- The view can be declared "transparent", through setTransparent(true).
In order to make translucency work in combination with the built-in Swing double-buffering, on Unix/X11 platforms with Java versions older than 1.6, you need to use the JVM option -Dsun.java2d.pmoffscreen=false.

Double and Triple Buffering

Double buffering prevents the screen from flickering when many objects are being manipulated. IlvManagerView is a lightweight Java component and cannot manage double buffering on its own. To use double buffering in a Swing application, just place your view in an IlvJManagerViewPanel or IlvJScrollManagerView. Note that in a Swing application, it is not necessary to set double buffering on (using setDoubleBuffering(boolean)), since Swing already handles the double buffering of all components. For AWT, non-Swing applications, place your view in an IlvManagerViewPanel or IlvScrollManagerView.
Using triple buffering, static background layers are drawn in an additional off-screen image, and this image is used instead of redrawing the background graphic objects to speed up your application. Triple buffering is activated by calling setTripleBufferedLayerCount(int).

Handling User Input

A view interactor processes AWT events and controls behavior that can be applied to a view as a whole, that is, affecting all the objects contained in the view. View interactors are subclasses of IlvManagerViewInteractor that are attached to the view. The following code example shows how to add a zoom interactor:
```
   IlvManager manager = new IlvManager();
   IlvManagerView mgrview = new IlvManagerView(manager);
   IlvZoomViewInteractor zoomInteractor;
   zoomButton = new Button("Zoom In");
   ...
   zoomButton.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent evt) {
       if (zoomInteractor == null)
         zoomInteractor = new IlvZoomViewInteractor();
       if (mgrview.getInteractor() != zoomInteractor) 
         mgrview.setInteractor(zoomInteractor);
     }
   }); 
 
```
Note: use setWheelZoomingEnabled(boolean) to allow users to zoom in and out of a view using the mouse wheel. For scrolling using the mouse wheel, encapsulate the manager view in a IlvJScrollManagerView and use its method setWheelScrollingEnabled.
A manager view manages a stack of view interactors, only the interactor on top of the interactor stack is active. Subclasses of IlvManagerViewInteractor class allow you to perform different tasks on the view. For example, IlvZoomViewInteractor allows the user to zoom to a rectangle dragged over the view using the mouse.

Listening for Manager View Changes

When the manager displayed by a view changes, the view fires a ManagerChangedEvent. To handle these events, a ManagerChangedListener implementation instance must be registered with this view by calling addManagerChangedListener(ManagerChangedListener). To remove this listener call removeManagerChangedListener(ManagerChangedListener).
When the transformer of the view changes, the view fires a TransformerChangedEvent event. To handle these events a TransformerListener implementation instance must be registered with this view by calling addTransformerListener(TransformerListener). To remove this listener call removeTransformerListener(TransformerListener).
When the interactor of the view changes, the view fires a InteractorChangedEvent event. To handle these events a InteractorListener implementation instance must be registered with this view by calling addInteractorListener(InteractorListener). To remove this listener call removeInteractorListener(InteractorListener).

Synchronization on Manager View

In multithreaded client side applications, all changes on the manager view should be done in the AWT thread, to avoid synchronization problems and deadlocks when the AWT thread draws the component while other threads try to change it. In multithreaded server side applications, several threads can access the manager view. In this case, it is recommended to take the manager lock before taking the view lock as sketched below:
```
  synchronized (view.getManager().getTreeLock()) {
    synchronized (view) {
       ...
    }
  }
 
```
JViews code that needs both locks always obeys this order. Hence, taking locks in opposite order can lead to deadlocks and is not recommended.
Other notes

Like every AWT component, the manager view has a locale and a component orientation. Different to other AWT components, the manager view does not inherit the locale from a parent component but always uses the locale that was specified at construction time (or IlvLocaleUtil.getCurrentULocale() if none was specified), or that was set explicitely. Changing the locale or component orientation may affect all objects in a manager, hence it is most efficiently done when the manager is still empty.

  - BLINKING_AUTOMATIC
```
public static final int BLINKING_AUTOMATIC
```
    Automatic mode for the blinking behavior. Objects displayed in this view with blinking colors, blinking paints, blinking actions or blinking periods actually only blink if the view is showing. If the view is not showing, the blinking timers do not occupy any resources for this view.

  - BLINKING_ENABLED
```
public static final int BLINKING_ENABLED
```
    Mode ON for the blinking behavior. Objects displayed in this view with blinking colors, blinking paints, blinking actions or blinking periods blink even if the view is not showing. Since the view is not showing, you cannot see the blinking, but the blinking timers still occupy resources for this view. This is mainly useful in advanced situations where the drawing buffer of the non-showing view is copied to some other showing component.

  - BLINKING_DISABLED
```
public static final int BLINKING_DISABLED
```
    Mode OFF for the blinking behavior. Objects displayed in this view with blinking colors, blinking paints, blinking actions or blinking periods do not blink at all. This is useful for additional views such as an overview which does not require blinking behaviors because they are already shown in the main view. Disabling blinking behaviors releases all resources of blinking timers.

  - setManager
```
public final void setManager(IlvManager manager)
```
    Changes the manager displayed by this manager view. If the view should be garbage collected while its current manager is still needed, you can call it with a null argument to detach the view from its manager. When the manager changes, a ManagerChangedEvent is sent to all the manager changed listeners.
    
    Parameters:
    
    manager - The new manager.

  - setTransformer
```
public final void setTransformer(IlvTransformer t)
```
    Changes the transformer of the view. Each view has its own transformer to define the area of the manager that the view is displaying and also to define the level of zoom and rotation applied to objects. Note that this method does not repaint the view. You must call repaint in order to do it. This method will send a transformer changed event to all transformer listeners.
    
    Parameters:
    
    t - The transformer. If the value is null, nothing is performed and no exception is raised.

  - addTransformer
```
public final void addTransformer(IlvTransformer t)
```
    Adds the transformer on the view (composes the existing transformer with the new one). This is equivalent to calling setTransformer with the transformer: oldTransformer.compose(t). Note that this method does not repaint the view. You must call repaint in order to do it. This method will send a transformer changed event to all transformer listeners.
    
    Parameters:
    
    t - The transformer. If the value is null, nothing is performed and no exception is raised.

  - isKeepingAspectRatio
```
public final boolean isKeepingAspectRatio()
```
    Returns true if the view keeps the aspect ratio; otherwise it returns false. Since any type of transformation can be used to display the contents of a manager in a view, different zoom levels can be used along the x and y axes. This causes a distorted image. When KeepingAspectRatio is true, the view will verify each modification of its transformer so that the zoom factor remains the same along the x axis and the y axis.
    
    See Also:
    
    setKeepingAspectRatio(boolean)
  - setKeepingAspectRatio
```
public final void setKeepingAspectRatio(boolean set)
```
    Allows or inhibits the ability to have different zoom factors along the x and y axes. Since any type of transformation can be used to display the contents of a manager in a view, different zoom levels can be used along the x and y axes. This causes a distorted image. When KeepingAspectRatio is true, the view will verify each modification of its transformer so that the zoom factor remains the same along the x axis and the y axis.

```
    Sets the minimal and maximal zoom factor allowed for the view. The minimal and maximal zoom factor is valid in the x and y directions. When a minimal and maximal zoom factor is set, the view will verify each modification of its transformer so that the zoom factor remains in the range between the minimal and maximal value. The minimal zoom factor must be at least 0. The maximal zoom factor must be larger than 0.
    
    Parameters:

  - setInteractor
```
public void setInteractor(IlvManagerViewInteractor interactor)
```
    Changes the interactor of the view. This method simply removes all the interactors installed and calls pushInteractor. The specified interactor becomes active for the view. This means that all AWT events received by the view will be processed by this interactor. Note that an interactor can only be used in one view at a time. So it is an error to set the same interactor to several views even if this does not generate any exception. An interactor changed event is sent to all the interactor listeners.
    
    Parameters:
    
    interactor - The new interactor.
    
    See Also:

```
public IlvManagerViewInteractor getInteractor()
```
    Returns the interactor of the view, if any, or null otherwise. If several interactors have been pushed to the view, this method returns the interactor that is on top of the interactor stack, that is, the interactor that is currently active.

```
public void pushInteractor(IlvManagerViewInteractor interactor,
                           AWTEvent evt)
```
    Adds the specified interactor to the top of the interactor stack. The interactor becomes active for the view. This means that all AWT events received by the view will be processed by this interactor. All other interactors (that are not on top of the stack) no longer receive events. The event that is passed as a parameter is processed by the interactor immediately. Note that an interactor can only be used in one view at a time. So it is an error to push the same interactor to several views even if this does not generate an exception. An interactor changed event is sent to all the interactor listeners.
    
    Parameters:
    
    interactor - The interactor. If the value is null, no action is performed and no exception is raised.
    
    evt - The event that causes the push.

```
public void pushInteractor(IlvManagerViewInteractor interactor)
```
    Adds the specified interactor to the top of the interactor stack. This interactor becomes active for the view. This means that all AWT events received by the view will be processed by this interactor. All other interactors (that are not on top of the stack) no longer receive events.

  - popInteractor
```
public IlvManagerViewInteractor popInteractor()
```
    Removes an interactor from the top of the interactor stack. This interactor is no longer active. It will not receive any events. The interactor that was just below in the interactor stack (if any) becomes active. An interactor changed event is sent to all the interactor listeners.
    
    Returns:
    
    The removed interactor, or null if the interactor stack is empty.

    Returns true if the view is transparent. The default value is false.
    
    See Also:
    
    setTransparent(boolean)
  - setTransparent
```
public final void setTransparent(boolean transparent)
```
    Changes the transparency of the view. When the manager view is transparent, the background of the view is not filled with the background color. The transparency of the view will only work if there is no background pattern associated with the view. The default value is false.
    When setting the view transparent, or when using a transparent background color of the view, it might be necessary to set the background of the container of the view to non-opaque (for Swing components) or to a transparent color (for AWT components). For example, if the view is contained in a IlvJScrollManagerView, the code is:
```
 scroller = new IlvJScrollManagerView(managerView);
 // set a transparent background color
 scroller.setBackground(new Color(0,0,0,0));
 // set the scroll manager view nonopaque 
 scroller.setOpaque(false);
 // set the manager view transparent
 managerView.setTransparent(true);
 
```
    Parameters:
    
    transparent - Set to true to specify a transparent view.

    See Also:
    
    setAntialiasing(boolean)
  - setAntialiasing
```
public final void setAntialiasing(boolean set)
```
    Changes the antialiasing mode of the view.
    The default value is false.
    Note that this does not affect the antialiasing mode of the text object such as IlvText, IlvLabel, IlvZoomableLabel and so on. Text objects have their own antialiasing flag and do not depend on this flag.
    
    Parameters:
    
    set - true to turn on antialiasing mode.
    
    See Also:
    
    isAntialiasing()
  - isAutoFitToContents
```
public final boolean isAutoFitToContents()
```
    Returns true if the view is in autofit mode. In this mode, each time the view is resized and each time the contents of the manager displayed by this view changes, the transformer of the view is adjusted so that the full contents of the manager becomes visible. For this reason, it is useless to change the transformer of the view when the view is in the autofit mode. By default the view is not in this mode.
    
    See Also:
    
    setAutoFitToContents(boolean)

                                       int maxNumberOfIterations)
```
    Changes the autofit mode of the view. In this mode, each time the view is resized and each time the contents of the manager displayed by this view changes, the transformer of the view is adjusted so that the specified area of the manager becomes visible. For this reason, it is useless to change the transformer of the view when the view is in the autofit mode. By default the view is not in this mode.
    The area is provided by the FitAreaCalculator that can calculate the area depending on dynamic conditions. Margins are preserved and a specified number of iterations is used for computing the optimal transformer. For details about these parameters, see fitTransformerToArea.
    
    Parameters:
    
    set - true to turn on the autofit mode.
    
    insets - The margins around the manager contents. Set this value to null for no margins.
    
    areaCalculator - The calculator for the area to be fit. If null, then the bounding box of all visible graphics is used.
    
    maxNumberOfIterations - The maximum number of iterations to be used for computing the optimal transformer.

  - setDoubleBuffering
```
public final void setDoubleBuffering(boolean set)
```
    Sets the manager view in double-buffering mode.
    The double-buffering technique is used to remove flickering when the view or some area of the view is repainted. When the view is in double-buffering mode, the repainting is first done on an off-screen bitmap and then the bitmap is copied to the screen.
    Since the IlvManagerView is a lightweight component, the double buffering cannot be achieved by this class alone. The view of the manager must be encapsulated in a heavyweight component; that is why in an AWT application, the IlvManagerView must be encapsulated in an IlvManagerViewPanel or an IlvScrollManagerView. In a Swing application you may encapsulate the view by an IlvJScrollManagerView or IlvJManagerViewPanel. Note that in a Swing application, it is not necessary to set double buffering on, since Swing already handles the double buffering of all components.
    Independently of this setting, the IlvManagerView uses a double buffer also to speed up the drawing (in particular scrolling and panning via translate(double, double, boolean)) when optimized translation is enabled. If you want to avoid any use of a double buffer, you need to call
```
setDoubleBuffering(false);
 setOptimizedTranslation(false);
 
```
    This setting should not be confused with the double-buffering done by Swing. The Swing double-buffering can be turned off either locally, by calling component.JComponent.setDoubleBuffered(boolean)(false} on this view and all its ancestors up to the JRootPane, or globally, by calling repaintManager.setDoubleBufferingEnabled(false).
    Parameters:
    
    set - true to turn on double buffering.

    setDoubleBuffering(boolean)
  - setDoubleBufferFrozen
```
public void setDoubleBufferFrozen(boolean freeze)
```
    Sets whether the double buffer is frozen.
    When frozen, the double buffer is not updated with the most recent data. This method enables you to temporarily hide changes in the manager from being displayed. When the double buffer is frozen, repainting draws the frozen contents of the double buffer and not current manager content.
    When the double buffer is unfrozen, the next repaint draws the current manager content. We recommend that you call Component.repaint() immediately after unfreezing the double buffer.
    Note: Double buffering must be enabled before calling setDoubleBufferFrozen. To set double buffering, call setDoubleBuffering(boolean).
    Note: Proper interaction with the manager is not possible while the double buffer is frozen. We recommend that the buffer is frozen for very short time periods only.
    
    Parameters:
    
    freeze - Set to true to freeze the double buffer. Set to false to unfreeze the double buffer.
    
    Throws:
    
    RuntimeException - when setDoubleBufferFrozen is called while double buffering is not enabled. To set double buffering, call setDoubleBuffering(boolean).

    Returns the visibility of the specified layer in the view. The layers of a manager can be set as visible or invisible on a per-view basis. This method indicates if the specified layer is visible for this view only. If the method returns true, it does not necessarily mean that the layer is displayed because the layer may be globally invisible. To determine if a layer is displayed in this view, you should use the method: IlvManager.isVisible(IlvManagerView view, int layer).

    layer - The index of the layer.
    
    Returns:
    
    true if the layer is visible, otherwise false.

    Computes the rectangle that contains all the graphic objects of the manager of the view, for a given transformer. Notice the following:
    - Layers that are not visible for the view are not taken into account (see IlvManager.isVisible(int) and isVisible(int)).
    - Layers for which isContributingToViewBBox(int) returns false are not taken into account.
    - If view margins are specified, they are taken into account.
    Parameters:
    
    t - Transformer used to compute the bbox. A null value is equivalent to an identity transformer.

    Modifies the transformer of the manager view so that all objects are visible in the view.
    Notice the following:
    - This method computes the transformer based on the size of the view. Therefore, if the view is not visible, the method does nothing. See fitTransformerToContent(boolean) if you want to call this operation before the view is visible.
    - This method does not repaint the view, so you must call Component.repaint() if you need to do so.

public void fitTransformerToContent(boolean delayUntilShowing)
```
    Modifies the transformer of the manager view so that all objects are visible in the view.
    Notice the following:
    - This method can be called when the view is not yet showing or visible (see Component.isShowing()). If the view is not yet showing but the parameter delayUntilShowing is true, it waits until the view becomes showing before doing the operation. This ensures that the transformer will be adapted to the effective size of the showing view even when called at a non-showing view.
    - This method repaints the view automatically after modifying the transformer.
    This method calls the method fitTransformerToContent(Insets, int, boolean) and sets the insets to null (no margins) and the number of iterations to 10. For details, see the documentation of this method.
    Parameters:
    
    delayUntilShowing - If true and the view is not yet showing, it waits until the view becomes showing and then fits the transformer to the size. If false or if the view is already showing, it fits the transformer immediately to the size.

    Modifies the manager view transformer so that all objects are visible in the view, margins are preserved and a specified number of iterations is used for computing the optimal transformer.
    Notice the following:
    - Layers that are not visible for the view are not taken into account (see IlvManager.isVisible(int) and isVisible(int)).
    - Layers for which isContributingToViewBBox(int) returns false are not taken into account.
    - If nonzoomable objects are contained in the manager (see IlvGraphic.zoomable()), this method may not be able to find the exact transformer that perfectly fits the visible area of the view. In this case, call this method with maxNumberOfIterations set to a greater value to obtain a result closer to the optimum.
    - This method computes the transformer based on the size of the view. Therefore, if the view is not visible, the method does nothing. See fitTransformerToContent(Insets, int, boolean) if you want to call this operation before the view is visible.

public IlvTransformer computeTransformerFitToArea(Insets insets,
                                                  IlvManagerView.FitAreaCalculator areaCalculator,
                                                  int maxNumberOfIterations)
```
    Computes the manager view transformer that will fit a specific area to be visible in the view. The area is provided by the FitAreaCalculator that can calculate the area depending on dynamic conditions. Margins are preserved and a specified number of iterations is used for computing the optimal transformer.
    For instance, in order to compute a transformer that will zoom to all selected objects, a FitAreaCalculator can be created that calculates the area of all the selected objects. If nonzoomable objects are selected (see IlvGraphic.zoomable()), this method may not be able to find the exact transformer that perfectly fits all the selected objects in the view. In this case, call this method with maxNumberOfIterations set to a greater value to obtain a result closer to the optimum.
    This method computes the transformer based on the size of the view. Therefore, if the view is not visible, or there is any other reason that an appropriate transformer cannot be computed, this method returns the view's current transformer.
    The returned transformer is meant to be applied through setTransformer(IlvTransformer), not addTransformer(IlvTransformer).
    
    Parameters:
    
    insets - The margins around the manager contents, in pixels. Set this value to null for no margins.
    
    areaCalculator - The calculator for the area to be fit. If null, then the bounding box of all visible graphics is used.
    
    maxNumberOfIterations - The maximum number of iterations to be used for computing the optimal transformer.
    
    Returns:
    
    The transformer that will best fit the specified area to the view.

  - ensureVisible
```
public void ensureVisible(IlvRect r)
```
    Modifies the transformer so that the specified rectangle becomes visible. Note that this method does not zoom the view but only translates it.
    
    Parameters:
    
    r - The rectangle in the view coordinate system.
  - ensureVisible
```
public void ensureVisible(IlvPoint point)
```
    Modifies the transformer so that the specified point becomes visible.
    
    Specified by:
    
    ensureVisible in interface IlvObjectInteractorContext
    
    Parameters:
    
    point - The point in the view coordinate system.
  - visibleRect
```
public Rectangle visibleRect()
```
    Returns the visible rectangle of the view. This is the intersection of the visible rectangle of this view (0, 0, getWidth(), getHeight()) and all visible rectangles of its ancestors.
  - verifyTransformer
```
public void verifyTransformer()
```
    Checks a transformer before setting it to a view. This method is called every time the transformer of the view is changed by calling setTransformer or addTransformer. It is used to verify that the zoom factor is the same along the x and y axis if the view must maintain the aspect ratio and is within the range of the minimal and maximal zoom factor. You do not need to call this method.

                       boolean redraw)
```
    Zooms the transformer of the view.
    
    Parameters:
    
    point - The center of the zoom. The position of this point is not changed on the view.
    
    sx - The x scaling factor.
    
    sy - The y scaling factor.
    
    redraw - If true, the view is redrawn.
  - isOptimizedTranslation
```
public boolean isOptimizedTranslation()
```
    Returns an indication of whether the translation of the manager view content is optimized or not. When translations are optimized, the translate method will translate the area of the view that remains visible by a BIT BLIT operation. For this reason only the newly visible areas are repainted. The default value is true.
    The optimized translation works best in combination with double buffering. If double buffering is permanently disabled but optimized translation is enabled, the view might decide to use a double buffering temporarily for a sequence of multiple translation, for instance when scrolling the view continuously. This improves the speed. To ensure that no double buffering is used at all, disable double buffering and optimized translation together.

```
    Translates the view. This method translates the transformer of the view.
    
    Parameters:

  - setRepaintSkipThreshold
```
public void setRepaintSkipThreshold(long delay)
```
    Sets the minimum delay between repaint requests. If repeated repaints are called too often, some of the repaints will be skipped in order to keep a good UI responsiveness. Note that this feature works only if the manager view is under THREADED_REDRAW mode. So if you do not want your repaint requests skipped, you can turn the view into DIRECT_REDRAW mode.
    
    Parameters:
    
    delay - The minimum delay in millisecond between repaint requests.

  - setRedrawMode
```
public final void setRedrawMode(int mode)
```
    Changes the way invalid regions of the view are redrawn. The invalid regions are the regions invalidated by the method invalidateRect.
    
    Parameters:
    
    mode - Valid values for mode are IlvManagerView.DIRECT_REDRAW and IlvManagerView.THREADED_REDRAW. For a THREADED_REDRAW mode, the invalid regions are redrawn by the repainting thread of AWT; for DIRECT_REDRAW, the regions are redrawn directly by the current thread.

  - setBlinkingMode
```
public final void setBlinkingMode(int mode)
```
    Sets the mode of the blinking behavior of graphic objects displayed in this view. This affects objects with blinking colors, blinking paints, blinking actions or blinking periods. Valid options are:
    - BLINKING_AUTOMATIC (the default) - Objects with blinking behavior displayed in this view actually only blink if the view is showing. If the view is not showing, the blinking timers do not occupy any resources for this view.
    - BLINKING_ENABLED - Objects with blinking behavior displayed in this view blink even if the view is not showing. Since the view is not showing, you cannot see the blinking, but the blinking timers still occupy resources for this view. This is mainly useful in advanced situations where the drawing buffer of the non-showing view is copied to some other showing component.
    - BLINKING_DISABLED - Objects with blinking behavior displayed in this view do not blink at all. This is useful for additional views such as an overview which does not require blinking behaviors because they are already shown in the main view. Disabling blinking behavior releases all resources of blinking timers. If many blinking objects are displayed in many views, disabling blinking for some of the views increases the performance of the system.

    Normally, turning the mouse wheel down (towards the user) zooms in, and turning the wheel up (away from the user) zooms out. Wheel zooming inversion reverses the sense of the zoom: Turning the wheel down (towards the user) zooms out, turning the wheel up (away from the user) zooms in.
    Note: This only has an effect if the wheel zooming is enabled.
    
    Parameters:
    
    inverted - Set to true to invert the the mouse wheel zooming facility. Set to false for standard wheel zooming.

public void invalidateTripleBuffer(boolean repaint)
```
    Invalidates the triple buffer. This method must be called manually when the content of a triple-buffered layer changes.

public void invalidateTripleBuffer(IlvRect rect,
                                   boolean repaint)
```
    Invalidates partially the triple buffer. This method is designed to indicate that part of the triple buffer is invalid and need to be refreshed.
    
    Parameters:
    
    rect - The dirty rectangle to be refreshed.
    
    repaint - Indicates whether a repaint is needed immediately

    JViews 8.1
  - setTripleBufferedLayerCount
```
public void setTripleBufferedLayerCount(int n)
```
    Sets the number of triple-buffered layers for this view. When the value is set to n, layers with indices in the range of [0, n-1] will be triple buffered. All layers that are triple buffered are drawn only once in an internal offscreen image. Further repainting of the view will simply display the bitmap. Triple buffering is then useful in an application that has a set of background layers that do not change. It is also important that the view does not zoom or pan excessively because changing the transformer of the view will invalidate and recompute the triple buffer.
    
    Parameters:
    
    n - The number of triple-buffered layers.

  - getPopupMenu
```
public JPopupMenu getPopupMenu(IlvPoint p,
                               IlvPopupMenuManager popupManager)
```
    Returns the Swing pop-up menu to be displayed when the pop-up is triggered at a specified location inside the manager view.
    You can override this method to display different pop-up menus over different parts of your manager view. This method can return null to turn off the pop-up menu for this manager view.
    The default implementation tests whether there is a graphic object at the specified location. If there is one, it returns the pop-up menu of this graphic object. Otherwise it returns the pop-up menu of the main manager of this manager view.
    Note: Before calling this method you must enable the manager view pop-up menu mechanism by calling IlvPopupMenuManager.registerView(ilog.views.IlvManagerView).
    
    Parameters:
    
    p - The location of the mouse in view coordinates.
    
    popupManager - The pop-up menu manager.
    
    Returns:
    
    The Swing pop-up menu.

```
    Returns the Swing pop-up menu to be displayed when the pop-up is triggered at a specified location inside the manager view. This calls IlvGraphic.getPopupMenu(IlvPoint, IlvTransformer, IlvManagerView, IlvPopupMenuManager) on the graphic object.
    
    Parameters:
    
    obj - The graphic object.
    
    p - The location of the mouse in view coordinates.
    
    popupManager - The pop-up menu manager.

```
public void setSelectedWhenPopupPreferred(boolean enable)
```
    Sets whether getPopupMenu(IlvPoint,IlvPopupMenuManager) returns preferably the topmost selected object. If enabled and the pop-up menu is triggered at a point with many overlapping objects, the pop-up menu of the topmost selected object is chosen. If disabled and the pop-up menu is triggered at a point with many overlapping objects, the pop-up menu of the topmost object is chosen whether it is selected or not. If the pop-up menu is triggered at a point where no objects overlap, this option has no effect.

  - initDisplayInfo
```
public static void initDisplayInfo()
```
    Initializes the information about the display. This includes information about the screen resolution and the number of displays. Normally, you don't need to call this method since the display information is automatically initialized on startup. The only reason to call this method is when you change the screen resolution or the number of displays while JViews is running.
