All Implemented Interfaces:
ILcdCloneable, ILcdPropertyChangeSource, ILcdGXYEditor, ILcdGXYEditorProvider, ILcdGXYPainter, ILcdGXYPainterProvider, ILcdGXYPathPainter, Serializable, Cloneable
public class TLcdGXYShapePainter extends Object implements ILcdGXYPainterProvider, ILcdGXYEditorProvider, ILcdGXYPathPainter, ILcdGXYEditor, ILcdPropertyChangeSource

A painter and editor for all supported shape types.

Supported objects

All objects implementing or pointing to one of the following ILcdShape subtypes:
  • ILcdCircleBy3Points, ILcdCircle, and ILcdEllipse
  • ILcdGeoBuffer, ILcdVariableGeoBuffer, TLcdLonLatBuffer, and TLcdLonLatHeightBuffer
  • ILcdPolygon, ILcdComplexPolygon, and TLcdRoundedPolygon
  • ILcdPolyline and TLcdRoundedPolyline
  • ILcdArcBand, ILcdArc, ILcdCircularArcBy3Points, ILcdCircularArcByBulge, and ILcdCircularArcByCenterPoint
  • ILcdText
  • ILcdBounds
  • ILcdShapeList
  • ILcdCurve, ILcdRing, and ILcdCompositeCurve
  • ILcdExtrudedShape (2D representation only)
If multiple interfaces are implemented, only one is taken into consideration. More specific interfaces have priority over less specific interfaces (e.g. ILcdCircle over ILcdCurve). ILcdPointList is also supported as a fallback, and interpreted as an ILcdPolyline.

Styling

The styling can be configured (for all shape types at once) by using one of the following methods:

    • getGXYPainter

      public ILcdGXYPainter getGXYPainter(Object aObject)
      Finds an ILcdGXYPainter that can be used to paint or locate the object passed.

      The painter provider is responsible for setting the object to the painter before returning the painter. An implementation should therefore have the following structure: 

      
 public ILcdGXYPainter getGXYPainter(Object aObject) {
   ILcdGXYPainter painter = ... // find the painter for the object
   if (painter != null) {
    painter.setObject(aObject);
   }
   return painter;
 }

      This method checks the type of the given object, and returns a default painter for it. See also the class doc.

      Specified by:
      getGXYPainter in interface ILcdGXYPainterProvider
      Parameters:
      aObject - the object to find a painter for
      Returns:
      a painter that can be used to paint or locate the object; or null if no painter could be found for the given object, or the object could not be set on the retrieved painter.

    • getGXYEditor

      public ILcdGXYEditor getGXYEditor(Object aObject)
      Finds an ILcdGXYEditor that can be used to edit the object passed.

      The editor provider is responsible for setting the object to the editor before returning the editor. An implementation should therefore have the following structure: 

      
 public ILcdGXYEditor getGXYEditor(Object aObject) {
   ILcdGXYEditor editor = ... // find the editor for the object
   editor.setObject( aObject );
   return editor;
 }

      This method checks the type of the given object, and returns a default editor for it. See also the class doc.

      Specified by:
      getGXYEditor in interface ILcdGXYEditorProvider
      Parameters:
      aObject - the object to find a painter for
      Returns:
      an editor that can be used to edit the object.

    • edit

      public boolean edit(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext)
      Description copied from interface: ILcdGXYEditor
      Defines how an object shall be edited by this editor, taking into account the mode and the context passed.

      The mode passed indicates how the interaction should be interpreted. It can be one of the following:

      • TRANSLATED
      • RESHAPED
      • START_CREATION
      • CREATING
      • END_CREATION

      The first two modes designate that the object should be modified, the last three modes are passed when initializing an object. From an implementation point of view there is no difference between TRANSLATED and RESHAPED. These constants only differ in semantics. For ILcdShape objects TRANSLATED can be seen as the mode that will be passed when the shape as a whole is moved. RESHAPED is used more often for moving part of a shape.

      The context contains information on the user interaction at hand. The methods getX and getY contain the location(s) of the user interaction. The methods getDeltaX and getDeltaY contain the distance(s) over which the user interaction is taking place. For example, getX and getY may contain the current mouse location while getDeltaX and getDeltaY contain the distance over which the mouse has been dragged. The editing behavior can take into account multiple locations, to respond to, for example, multi-touch input.

      When a snap target is accepted, the implementation of this method should take that fact into account when editing or initializing an object.

      Specified by:
      edit in interface ILcdGXYEditor
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aMode - indicates how the user interaction should be interpreted. Is one of the following:
      • TRANSLATED,
      • RESHAPED,
      • START_CREATION,
      • CREATING,
      • END_CREATION.
      aGXYContext - contains information on the user interaction and the transformations to transform from view space to the object model space.
      Returns:
      true if the object has changed when this method returns, false otherwise.
      See Also:

    • getCreationClickCount

      public int getCreationClickCount()
      Description copied from interface: ILcdGXYEditor
      Returns the number user interactions required to complete the initialization of an object set to this editor. For example, for a circle this can be two: one to determine the center point of the circle and one to determine the radius of the circle. A negative number indicates that there is no upper limit to the number of user interactions. For example, for a polyline this could be -2: it requires a minimum of two clicks to establish a polyline, but there is no upper limit on the number of polyline points.
      Specified by:
      getCreationClickCount in interface ILcdGXYEditor
      Returns:
      the number of user interactions required to initialize the object set to this editor.

    • acceptSnapTarget

      public boolean acceptSnapTarget(Graphics aGraphics, ILcdGXYContext aGXYContext)
      Description copied from interface: ILcdGXYEditor
      Returns whether the object set to the editor can be edited so that (part of) the object snaps to the object passed as snap target in the context. If the snap target is accepted, a call to the edit method with this context passed should edit the object so that (part of) the object snaps to the object passed as snap target in the context.

      The context contains information on the user interaction at hand: the current location of the user interaction, given by its X and Y coordinates, and the distance in X direction and distance in Y direction over which the user interaction is taking place. For example, getX and getY may contain the current mouse location while getDeltaX and getDeltaY contain the distance over which the mouse has been dragged. The context also contains the candidate snap target and the layer the snap target is contained in.

      Specified by:
      acceptSnapTarget in interface ILcdGXYEditor
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aGXYContext - the context containing the information on the user interaction and the snap target.
      Returns:
      whether the object set to the editor can be edited so that (part of) the object snaps to the object passed as snap target in the context.

    • setObject

      public void setObject(Object aObject)
      Description copied from interface: ILcdGXYPainter
      Sets the Object for which the representation shall be handled by this painter.

      Setting the object on the painter may have an effect on the internal state of the painter, for example, the color to use.

      When the object is set to a painter, the context parameter in subsequent calls to methods in this class must contain a layer that contains this object and for which the painter for this object is this painter.

      Specified by:
      setObject in interface ILcdGXYEditor
      Specified by:
      setObject in interface ILcdGXYPainter

    • getObject

      public Object getObject()
      Description copied from interface: ILcdGXYPainter
      Returns the Object for which the representation is currently being handled by this painter.
      Specified by:
      getObject in interface ILcdGXYEditor
      Specified by:

    • paint

      public void paint(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext)
      Description copied from interface: ILcdGXYPainter
      Displays the representation of the object in the given mode on the Graphics passed, taking into account the supplied context.

      The visual representation of an object depends on the context. Depending on the context (e.g. is the location covered by the view), an object may or may not have a representation. The context contains:

      • transformations which allow to compute the location in view space of points and bounds given in model, space
      • a pen which can connect points with a line or create arcs around a point,
      • the view for which the object's representation must be painted. This can be useful when the painted object depends on the scale of the view, or the presence of other layers in the view.
      • the current location(s) of the mouse or input device and the last location(s) the mouse or input device was pressed.

      The mode passed in this method indicates what part of the object must be painted, whether it should be painted as selected or not, and whether user interaction (via mouse movements) must be taken into account.

      When the mode passed contains either TRANSLATING, RESHAPING or CREATING, this method is also responsible for interpreting interaction on the representation of an object and modifying the representation of the object accordingly. The painter is not responsible for modifying the object itself, this is done by a corresponding ILcdGXYEditor . Implementations of ILcdGXYPainter and ILcdGXYEditor interfaces must be consistent for an object: the painter must display the result of the user interaction on the object, while the editor is responsible for modifying the object as a result of the user interaction. A good practice to ensure a consistent implementation is to implement both the ILcdGXYPainter and ILcdGXYEditor interfaces in a single class.

      When the mode passed includes SNAPS, the part of the representation which corresponds to the object returned as snap target by the method snapTarget must be painted in order to provide the user with a visual indication of the snap target.

      The Graphics passed in this method can be different from the Graphics returned by a view due to techniques such as double buffering (as applied in Swing). Basic drawing operations must always be performed on the Graphics passed as an argument in this method.

      Specified by:
      paint in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aMode - the mode the object is represented in (see class documentation).
      aGXYContext - the ILcdGXYContext the drawing depends on.

    • boundsSFCT

      public void boundsSFCT(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext, ILcd2DEditableBounds aBoundsSFCT) throws TLcdNoBoundsException
      Description copied from interface: ILcdGXYPainter
      Sets the supplied bounds (in view coordinates, pixels) so that it encompasses the representation of the object in the given mode taking into account the given context.

      If this method returns without exception the bounds argument must encompass the representation of the object. A point outside the bounds will not be contained within the painted object.

      The bounds returned in this method can be seen as the equivalent in the view space of the bounds in the model space for ILcdBounded objects.

      Specified by:
      boundsSFCT in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aMode - the mode the object is represented in (see class documentation). For example, an object may be represented differently in SELECTED mode compared to DEFAULT mode. The returned bounds of the representation must take this different representation into account.
      aGXYContext - the context for which the representation of the object is painted. It contains amongst others the transformations from model to world and world to view.
      aBoundsSFCT - the bounds that must be adapted to encompass the representation of the object in the given mode and context. These bounds must not be taken into account when the method has thrown an exception.
      Throws:
      TLcdNoBoundsException - if no bounds can be determined for the representation of the object. This can happen when the object does not have a representation in the given context, for example when it is located in a part of the world which is not visible in the current view.

    • isTouched

      public boolean isTouched(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext)
      Description copied from interface: ILcdGXYPainter
      Checks if the representation of the object in the given mode is touched at the location as defined in the supplied context.

      The location that must be taken into account to check whether the representation is touched can be retrieved from the context passed with the methods ILcdGXYContext.getX() and ILcdGXYContext.getY(). If the check is part of an ongoing operation of user interaction, for example, when the mouse is being dragged, the location of the start of the operation can also be taken into account using the methods ILcdGXYContext.getDeltaX() and ILcdGXYContext.getDeltaY(). The context contains the transformations required to convert this location into the equivalent location in model space. Implementations of this interface usually follow either of the following patterns:

      • transform the location of the interaction back to model space and compare the coordinates with the object in model space.
      • transform the location to world space and compare with a world representation of the object. This forces the painter into caching a world representation of the object. Caching a view representation of an object is not very practical as it would have to change whenever the view's scale changes or when it is panned. A world representation of an object only changes when the view's XYWorldReference changes, which happens less frequently.

      As the mode influences the way an object is represented, it must also be taken into account when checking whether that representation is being touched. When the mode contains CREATING, RESHAPING or TRANSLATING which indicate that the object must be represented in a state for an ongoing operation, the location of the start of the operation may be taken into account as mentioned above. The painting result can take into account multiple locations, to respond to, for example, multi-touch input. When the mode contains SELECTED, the painter should also check if the non-selected representation is touched, since these are always painted on top of each other.

      The boundsSFCT is often used to speed up the performance of this method as a location outside these bounds can never touch the representation of the object.

      Note that this method does not give an indication of what part of the object is touched. It is up to the painter implementations to provide methods to make this distinction. The method does also not indicate what sensitivity must be applied when checking if an object is touched. It is up to the implementation to decide what should be the maximum distance between the location given in the context and the closest relevant point or area of the representation of the object.

      Specified by:
      isTouched in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aMode - the mode the object is represented in
      aGXYContext - contains the location of the interaction and the transformations to convert this location into model coordinates
      Returns:
      true if the representation of the object in the given mode is touched by the location as defined in the context passed, false otherwise

    • anchorPointSFCT

      public void anchorPointSFCT(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext, Point aPointSFCT) throws TLcdNoBoundsException
      Description copied from interface: ILcdGXYPainter
      Moves the Point passed to the location (in view coordinates, pixels) of the anchor point of the representation of the object in the given mode taking into account the given context.

      The anchor point is an important point of the representation, typically the point which would be used when the object would be represented as a single point. The anchor point is mostly used to attach extra information to the representation of an object, for example, using labels. A typical implementation of this method for painters which can handle ILcdShape objects is the location of the focus point of the shape.

      Specified by:
      anchorPointSFCT in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aMode - the mode the object is painted in (see class documentation)
      aGXYContext - the context for which the representation of the object is painted. It contains amongst others the transformations from model to world and world to view.
      aPointSFCT - the point that has to be moved to the location of the anchor point of the representation of the object. This point must not be taken into account when the method has thrown a TLcdNoBoundsException.
      Throws:
      TLcdNoBoundsException - if no anchor point can be determined for the representation of the object. This can be when the object does not have a representation in the given context, for example when it is located in a part of the world which is not visible in the projection as set in the views world reference.

      Specified by:
      supportSnap in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aGXYContext - the context in which this object is represented and in which the editing of an object occurs.
      Returns:
      true if an object can be returned that can be used to snap to in the given context, false otherwise.

    • snapTarget

      public Object snapTarget(Graphics aGraphics, ILcdGXYContext aGXYContext)
      Description copied from interface: ILcdGXYPainter
      Returns an object that can be used as snapping target when graphically editing an object. For example, an object which is beneath the current mouse position (as given in the context).

      This method must only be called when supportSnap returns true for the given context.

      Specified by:
      snapTarget in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aGXYContext - the context in which this object is represented and in which the editing of an object occurs.
      Returns:
      an object that can be used as snapping target when graphically editing an object. It must be defined in the same model reference as the object set to this painter.

    • getCursor

      public Cursor getCursor(Graphics aGraphics, int aMode, ILcdGXYContext aGXYContext)
      Description copied from interface: ILcdGXYPainter
      Returns a cursor that clarifies the mode and context the painter is operating in. For example, when the mode is TRANSLATING, the cursor could be the MOVE cursor. When no specific cursor is required implementations must return null.
      Specified by:
      getCursor in interface ILcdGXYPainter
      Parameters:
      aGraphics - the Graphics on which the representation of the object is painted
      aMode - the rendering mode to return the cursor for.
      aGXYContext - the context in which the rendering occurs.
      Returns:
      a Cursor to indicate the type of operating aMode and aGXYContext. Returns null if no particular Cursor is required.

    • getDisplayName

      public String getDisplayName()
      Description copied from interface: ILcdGXYPainter
      Returns a textual representation of this painter. This can be useful when different representations of an object are handled by different painter implementations. Having a textual representation can facilitate choosing between different painter implementations.
      Specified by:
      getDisplayName in interface ILcdGXYEditor
      Specified by:
      getDisplayName in interface ILcdGXYPainter
      Returns:
      a textual representation of this painter.

    • addPropertyChangeListener

      public void addPropertyChangeListener(PropertyChangeListener aPropertyChangeListener)
      Description copied from interface: ILcdPropertyChangeSource

      Registers the given PropertyChangeListener to be notified when this object's properties change.

      In case you need to register a listener which keeps a reference to an object with a shorter life-time than this change source, you can use a ALcdWeakPropertyChangeListener instance as property change listener.

      Specified by:
      addPropertyChangeListener in interface ILcdPropertyChangeSource
      Parameters:
      aPropertyChangeListener - The listener to be notified
      See Also:

    • removePropertyChangeListener

      public void removePropertyChangeListener(PropertyChangeListener aPropertyChangeListener)
      Description copied from interface: ILcdPropertyChangeSource

      De-registers the given PropertyChangeListener from receiving property change events for this object.

      If the listener was added more than once, it will be notified one less time after being removed. If the listener is null, or was never added, no exception is thrown and no action is taken.

      Specified by:
      removePropertyChangeListener in interface ILcdPropertyChangeSource
      Parameters:
      aPropertyChangeListener - the listener that should no longer be notified of changes of this object's properties

      Parameters:
      aGXYContext - the graphics context
      aRenderMode - the rendering mode
      aAWTPathSFCT - the path to append to
      Returns:
      true if a discretization of the shape could be successfully appended to the path
