Direct Known Subclasses:

MapMatrixElement

public class MapCanvas

extends javax.swing.JPanel

implements java.awt.event.ComponentListener, java.awt.event.ActionListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, edu.psu.geovista.ui.event.SelectionListener, edu.psu.geovista.ui.event.IndicationListener, edu.psu.geovista.ui.event.DataSetListener, edu.psu.geovista.ui.event.SpatialExtentListener, ExcentricLabelClient

This class handles the rendering of layer-independent objects like tooltips and the image used for buffering, and manages the layers, which render themselves to the image. This class also transforms spatial data into user space. This class is intended to be used inside other components like the GeoMap or the PlotMatrix.
