public class TLcdGXYViewJPanel extends JPanel implements ILcdGXYView, ILcdRotationCapableGXYView, ILcdModelProducerListener, ILcdTreeLayered, ILcdAWTEventSource, ILcdStatusSource
An implementation of the ILcdGXYView interface as a javax.swing.JPanel.
In addition to the ILcdGXYView functionality, TLcdGXYViewJPanel supports rotation and can use an ILcdGXYLayerFactory to automatically create ILcdGXYLayer objects from models. It also offers the ability to subscribe to view invalidation events.

As with all Swing components, once the view has been realized, all code that might affect or depend on the state of that component should be executed in the event-dispatching thread. This includes all methods that can cause the view to repaint implicitly or explicitly.

This For a ready-to-use implementation to display maps, see TLcdMapJPanel.

    • setClassTraceOn

      public static void setClassTraceOn(boolean aClassTraceOn)
      Deprecated.
      This method has been deprecated. It is recommended to use the standard Java logging framework directly.
      Enables tracing for all instances of this class. If the argument is true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.
      Parameters:
      aClassTraceOn - if true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.

    • setTraceOn

      public void setTraceOn(boolean aTraceOn)
      Deprecated.
      This method has been deprecated. It is recommended to use the standard Java logging framework directly.

    • pan

      public void pan(int aDeltaX, int aDeltaY, boolean aRepaint)
      Changes the view and/or world origin of the view so that the view contents are panned by the specified AWT delta. Implementations of this method are allowed to only repaint newly exposed areas, hence this method is preferred over simply changing the world origin. The repaint behavior is controlled by the smart pan feature.
      Specified by:
      pan in interface ILcdGXYView
      Parameters:
      aDeltaX - the shift in the X direction in screen coordinates
      aDeltaY - the shift in the Y direction in screen coordinates
      aRepaint - if true, will trigger a repaint of the view's contents. Depending on the implementation, only the newly exposed areas may be painted. If false, the view is not repainted.

      Paints the view on the given Graphics. The painted image contains the following:
      • a background color;
      • the bodies of each contained layer's models. Each layer is asked to paint itself, from bottom to top;
      • the labels of each contained layer's models. Typically labels are painted on top of any bodies. The labels are painted by the layer itself, or by a view label painter, if it is set;
      • the selected bodies of each contained layer's models. Typically selections are painted on top of bodies and labels.
      • the selected labels of each contained layer's models. The labels are painted by the layer itself, or by a view label painter, if it is set;
      • corner icons, if any;
      • the controller handling user interaction.
      The view is allowed to reuse earlier painted results as long as they are valid. Invalidation of the contents may occur indirectly (e.g. by changing view or layer properties) or directly by calling one of the invalidate methods.

      public void moveLayerAt(int aIndex, ILcdLayer aLayer) throws NoSuchElementException, ArrayIndexOutOfBoundsException
      Description copied from interface: ILcdLayered
      Moves the given layer (which is already in ILcdLayered) to the existing index aIndex. When a layer is moved down, all layers in between the previous and future position of the given layer (including the layer at index aIndex) are moved one position up.

      Description copied from interface: ILcdTreeLayered

      Removes a layer from both the hierarchical layer structure and the flat list representation. When removing an ILcdLayerTreeNode all of its children will also be removed. An event will then be generated for every layer that has been removed (one for the node and one for each of its child layers).

      It is not possible to remove the root node

      Specified by:
      removeLayer in interface ILcdLayered
      Specified by:

      Description copied from interface: ILcdGXYView
      Adds the given ILcdGXYLayer to this ILcdGXYView. The layer is normally added to the top of the view's layers, but that is implementation specific. The view will be repainted depending on the result of isAutoUpdate. No action is performed if the given layer is already contained in the list.
      Specified by:
      addGXYLayer in interface ILcdGXYView
      Parameters:
      aLayer - the layer to add to this view

      public boolean addGXYLayer(ILcdGXYLayer aLayer, boolean aRepaint)
      Description copied from interface: ILcdGXYView
      Adds the given ILcdGXYLayer to this ILcdGXYView, forcing a repaint if desired. The layer is normally added to the top of the view's layers, but that is implementation specific. No action is performed if the given layer is already contained in the list.
      Specified by:
      addGXYLayer in interface ILcdGXYView
      Parameters:
      aLayer - the layer to add to this view

    • getNumberOfCachedBackgroundLayers

      public int getNumberOfCachedBackgroundLayers()
      Description copied from interface: ILcdGXYView
      Returns the number of layers whose combined representation is cached across repaints. The layers are always the bottommost layer objects; they are regarded as background layers.
      Specified by:
      getNumberOfCachedBackgroundLayers in interface ILcdGXYView
      Returns:
      the number of bottommost layers to cache
      See Also:

    • setNumberOfCachedBackgroundLayers

      public void setNumberOfCachedBackgroundLayers(int aNumberOfCachedBackgroundLayers)
      Description copied from interface: ILcdGXYView
      Sets the number of layers whose combined representation is cached across repaints. The layers are the bottommost layer objects; they are regarded as background layers.

      Caching background layers is useful when one upper real-time layer needs to be refreshed often, whereas the contents of the background layers seldom change. When a real-time layer changes and needs to be repainted, the cached representation of the background layers is reused, speeding up the paint process. When a background layer changes, all layers need to be repainted to update the view.

      Specified by:
      setNumberOfCachedBackgroundLayers in interface ILcdGXYView
      Parameters:
      aNumberOfCachedBackgroundLayers - the number of bottommost layers to cache. This number applies to the flat list of layers.

      Returns:
      true
      See Also:

    • getImage

      public Image getImage()
      Description copied from interface: ILcdGXYView
      Returns an Image of this view. The image has not been painted on by the controller. This method is guaranteed to return an up-to-date image: if the view has been invalidated in some way (e.g. when a layer has been removed) then this method first updates the view before returning an image. To improve performance and conserve memory, the view is allowed to cache, reuse and overwrite the image in subsequent repaints. NOTE: While using High DPI mode, this method will return an image which is bigger than the view dimensions reported by getWidth() and getHeight() methods.
      Specified by:
      getImage in interface ILcdGXYView
      Returns:
      an image containing the representation of this view

    • setBackground

      public void setBackground(Color aColor)

      Specified by:
      setBackground in interface ILcdGXYView
      Overrides:
      setBackground in class JComponent

    • setScale

      public void setScale(double aScale)
      Description copied from interface: ILcdGXYView
      Sets the scale of this view, repainting the view according to isAutoUpdate. The scale corresponds to the number of pixels per world unit, as determined by the ILcdXYWorldReference. Hence, increasing the scale zooms in, and decreasing the scale zooms out.

      A view displaying geographical data usually employs a scale in pixels per meter. As an example, to fit the world on a view that is 1000 pixels wide, a scale of about 1000 pixels/40.000km, or 1.0/40.000 is needed.

      For most use cases, we recommended setting the unitless map scale instead.

      Specified by:
      setScale in interface ILcdGXYView
      Parameters:
      aScale - the new scale of the view. The view is scaled using the world origin as center. The scale is limited so that it does not exceed the interval defined by the minimum and maximum scales.

    • setScale

      public void setScale(double aScaleX, double aScaleY, boolean aRepaint, boolean aAdjusting)
      Description copied from interface: ILcdGXYView
      Sets the scale along the x-axis and y-axis of this view, repainting the view according to isAutoUpdate.

      The scale corresponds to the number of pixels per world unit, as determined by the ILcdXYWorldReference. For example, a view displaying geographical data could use a scale in pixels per meter.

      The default implementation in this interface sets both scales to the geometric mean of the requested scales. The concrete view implementations do respect the individual scales.

      Specified by:
      setScale in interface ILcdGXYView
      Parameters:
      aScaleX - the new scale along the x-axis of the view.
      aScaleY - the new scale along the y-axis of the view.
      aRepaint - if true, the view is repainted. If false, the view is not repainted.
      aAdjusting - if true, the caller indicates that he will trigger another property change right after this call. This is reflected in the associated property change event.

    • setGXYController

      public void setGXYController(ILcdGXYController aGXYViewController)

      Makes the given ILcdGXYController handle the user interaction of the view. The view calls the controller's startInteraction method to make the controller aware of this fact, and calls the previous controller's terminateInteraction method, if any.

      Implementations of this method can direct input events to the controller by checking, for example, if the controller implements AWT input interfaces such as KeyListener and MouseListener.

      This view implementation recognizes the following listener interfaces, making sure to forward the relevant events:

      • ComponentListener
      • KeyListener
      • MouseListener
      • MouseMotionListener
      • MouseWheelListener
      In addition, this view also recognizes controllers implementing ILcdAWTEventListener. If this is the case, the view dispatch all events using ILcdAWTEventListener. For example, a mouse drag event is only delivered to the controller's handleAWTEvent, not its mouseDragged method. The listeners are automatically removed.
      Specified by:
      setGXYController in interface ILcdGXYView
      Parameters:
      aGXYViewController - the new controller of this view, or null if no controller is to be used

      public void invalidateRegionSelection(Rectangle aClip, boolean aRepaint, Object aSource, String aMessage)
      Description copied from interface: ILcdGXYView
      Asks the ILcdGXYView to invalidate its selection in the given AWT clip, optionally repainting the content asynchronously. A subsequent repaint will ask (at the least) all layers to draw their selection in the given clip, and may reuse earlier generated imagery for the bodies, labels, and rest of the view. This method is typically called when the selection of a small portion of the view needs to be redrawn, for example, when changing the selection in that area.
      Specified by:
      invalidateRegionSelection in interface ILcdGXYView
      Parameters:
      aClip - the clip to invalidate
      aRepaint - if true, the view is updated immediately, but the method will not wait for the update to finish. If false, the view is updated on the next paint or repaint method call.
      aSource - class instance calling the method. For tracing purposes.
      aMessage - a message associated to this method call. For tracing purposes.

      Description copied from interface: ILcdGXYView
      Asks the ILcdGXYView to invalidate its selection in the given AWT clip, optionally repainting the content synchronously. A subsequent repaint will ask (at the least) all layers to draw their selection in the given clip, and may reuse earlier generated imagery for the bodies, labels, and rest of the view. This method is typically called when the selection of a small portion of the view needs to be redrawn, for example, when changing the selection in that area.
      Specified by:
      invalidateRegionSelectionAndWait in interface ILcdGXYView
      Parameters:
      aClip - the clip to invalidate
      aRepaint - if true the ILcdGXYView will be updated immediately, and the method will block until the update is complete. If false, the view is updated on the next paint or repaint method call.
      aSource - class instance calling the method. For tracing purposes.
      aMessage - a message associated to this method call. For tracing purposes.

    • setAutoUpdate

      public void setAutoUpdate(boolean aAutoUpdate)
      Sets whether to update the view's representation automatically to keep it in sync with its state and the state of its models.

      When switching the autoUpdate property from false to true, a repaint will be triggered.

      Specified by:
      setAutoUpdate in interface ILcdView
      Parameters:
      aAutoUpdate - if true, the view automatically updates its representation on reception of any event that might require an update (e.g. when its properties change, when an Object in a model has changed, or when a model has been added/removed). If false, the view must be repainted manually.
      See Also:

    • isAutoUpdate

      public boolean isAutoUpdate()
      Description copied from interface: ILcdView
      Returns whether the view's contents are automatically updated when necessary.

    • setGXYViewLabelPainter

      public void setGXYViewLabelPainter(ILcdGXYViewLabelPainter aGXYViewLabelPainter)
      Sets the label painter algorithm for this ILcdGXYView. A view label painter handles the labels of all the view's layers. When the view label painter is null, the layers are asked to paint their labels themselves. This will override any configured view label placer.

      Note that it is recommended to use setGXYViewLabelPlacer instead. Label placers offer better decluttering behavior, more algorithm choices, support for asynchronous label placement, and easier customization.

      Parameters:
      aGXYViewLabelPainter - the painter handling this view's labels, or null
      See Also:

    • getGXYViewLabelPainter

      public ILcdGXYViewLabelPainter getGXYViewLabelPainter()
      Description copied from interface: ILcdGXYView
      Returns the label painting algorithm for this view. A view label painter handles the labels of all the view's layers. Hence, the layers are not asked to paint their labels if the view label painter is not null. The view label painter can be used for decluttering labels across all layers. To do this, it can select the objects that need a label and delegate the actual painting to the relevant layer's ILcdGXYLabelPainter.
      Specified by:
      getGXYViewLabelPainter in interface ILcdGXYView
      Returns:
      the painter handling this view's labels, or null

      public ILcdGXYViewLabelPlacer getGXYViewLabelPlacer()
      Description copied from interface: ILcdGXYView
      Returns the label placer for this view. A view label placer handles the labels of all the view's layers. The layers are only responsible for painting their labels while the label placer declutters the labels.
      Specified by:
      getGXYViewLabelPlacer in interface ILcdGXYView
      Returns:
      the label placer handling this view's labels, or null.

    • isAsynchronousAllowed

      public boolean isAsynchronousAllowed()
      Description copied from interface: ILcdGXYView

      Returns whether this view allows asynchronous operations. Painters, layers or other parts of a view should not perform asynchronous operations when this method returns false. If this method returns true, they can decide either way.

      When asynchronous operations are allowed, intermediate results of time-consuming asynchronous operations are displayed in order to provide an interactive user experience. For non-interactive applications, it is useful to disable asynchronous operations, since they can lead to more unpredictable results. Examples are tests, or server side functionality like the OGC WMS protocol which paints the view and returns it as an image. In these cases, you want the view to be painted completely without having to deal with intermediate results.

      Specified by:
      isAsynchronousAllowed in interface ILcdGXYView
      Returns:
      whether this view allows asynchronous operations.

    • setAsynchronousAllowed

      public void setAsynchronousAllowed(boolean aAsynchronousAllowed)

      Sets if asynchronous operation are allowed for this view. See ILcdGXYView.isAsynchronousAllowed() for more information.

      This method returns true by default.

      Note: it is advised to only modify this flag at construction time, not at runtime.

      Parameters:
      aAsynchronousAllowed - true to allow asynchronous operations.

    • isAntiAliased

      public boolean isAntiAliased()
      Description copied from interface: ILcdGXYView
      Specifies if anti-aliasing is enabled or not. Anti-aliasing makes lines and text appear smoother, but slows down rendering a little bit. If this property is false, it does not mean anti-aliasing is fully disabled. It only means anti-aliasing is not enabled on the view level, various layers and painters may still decide to enable anti-aliasing for what they render.
      Specified by:
      isAntiAliased in interface ILcdGXYView
      Returns:
      true if anti-aliasing is enabled, false otherwise.

    • setAntiAliased
