sim.portrayal.SimplePortrayal2D
All Implemented Interfaces:
Serializable, Portrayal, Portrayal2D
Direct Known Subclasses:

public class SimplePortrayal2D extends Object implements Portrayal2D, Serializable
The superclass of all 2D Simple Portrayals. Doesn't draw itself at all. Responds to hit testing by intersecting the hit testing rect with a width by height rectangle centered at 0,0. Responds to requests for inspectors by providing a basic LabelledList which shows all the portrayed object's object properties (see sim.util.SimpleProperties). Responds to inspector update requests by updating this same LabelledList.

    • draw

      public void draw(Object object, Graphics2D graphics, DrawInfo2D info)
      Description copied from interface: Portrayal2D
      Draw a the given object with an origin at (info.draw.x, info.draw.y), and with the coordinate system scaled by so that 1 unit is in the x and y directions are equal to info.draw.width and info.draw.height respectively in pixels. The rectangle given by info.clip specifies the only region in which it is necessary to draw. If info.precise is true, try to draw using real-valued high-resolution drawing rather than faster integer drawing. It is possible that object is null. The location of the object in the field may (and may not) be stored in info.location. The form of that location varies depending on the kind of field used.
      Specified by:
      draw in interface Portrayal2D
    • hitObject

      public boolean hitObject(Object object, DrawInfo2D range)
      Return true if the given object, when drawn, intersects with a provided rectangle, for hit testing purposes. The object is drawn with an origin at (info.draw.x, info.draw.y), and with the coordinate system scaled by so that 1 unit is in the x and y directions are equal to info.draw.width and info.draw.height respectively in pixels. The rectangle given by info.clip specifies the region to do hit testing in; often this region is actually of 0 width or height, which might represent a single point. It is possible that object is null. The location of the object in the field may (and may not) be stored in info.location. The form of that location varies depending on the kind of field used.
    • setSelected

      public boolean setSelected(LocationWrapper wrapper, boolean selected)
      Description copied from interface: Portrayal
      Change the portrayal state to reflect the fact that you've been selected or not selected. Always return true, except if you've received a setSelected(true) and in fact do not wish to be selectable, in which case return false in that sole situation.
      Specified by:
      setSelected in interface Portrayal
    • handleMouseEvent

      public boolean handleMouseEvent(GUIState guistate, Manipulating2D manipulating, LocationWrapper wrapper, MouseEvent event, DrawInfo2D fieldPortrayalDrawInfo, int type)
      Optionally handles a mouse event. At present, events are sent to SimplePortrayal2Ds representing objects which have been either selected or are presently hit by the event coordinates. The wrapper provides the field portrayal, object location, and object. Also provided are the display, event, the DrawInfo2D for the field portrayal, and the type of mouse event situation (either because the object was SELECTED or because it was HIT).

      To indicate that the event was handled, return true. The default blank implementation of this method simply returns false. Events are first sent to portrayals selected objects, until one of them handles the event. If none handled the event, then events are sent to portrayals of objects hit by the event, until one of *them* handles the event. If still no one has handled the event, then the Display2D will route the event to built-in mechanisms such selecting the object or inspecting it.

      If you're modifying or querying the model as a result of this event, be sure to lock on guistate.state.schedule before you do so.

    • getInspector

      public Inspector getInspector(LocationWrapper wrapper, GUIState state)
      Description copied from interface: Portrayal
      Provide an inspector for an object.
      Specified by:
      getInspector in interface Portrayal
    • getStatus

      public String getStatus(LocationWrapper wrapper)
      Description copied from interface: Portrayal
      Returns a simple, informative one-line description of the current status of the object, which may change at any time to reflect how the object is changing. A simple default would be just to return getName(wrapper).
      Specified by:
      getStatus in interface Portrayal
    • getName

      public String getName(LocationWrapper wrapper)
      Description copied from interface: Portrayal
      Returns a static, one-line name for the given object that is useful for a human to distinguish it from other objects. A simple default would be just to return "" + object.
      Specified by:
      getName in interface Portrayal
