MapNavLayer

public MapNavLayer(MapCanvas parent)

Method Detail

setCanvas

public void setCanvas(MapCanvas canvas)

Description copied from interface: Layer

Sets the map canvas on which this layer is displayed.

Specified by:

setCanvas in interface Layer

Overrides:

setCanvas in class BasicLayer

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent evt)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent evt)

Specified by:

stateChanged in interface javax.swing.event.ChangeListener

mapRegionChanged

public void mapRegionChanged(MapRegionEvent e)

Description copied from interface: Layer

When the associated canvas's map region is changed, this method is called to notify the layer of the change. Note that either a device window change (as a result of resizing the application window) or a data window change can cause this method to be invoked. Query the canvas' MapRegion object to get the changed values. Inside a mapRegionChanged() implementation, the layer typically needs to update its data contents accordingly.

Specified by:

mapRegionChanged in interface Layer

Overrides:

mapRegionChanged in class BasicLayer

handleEvent

public boolean handleEvent(java.util.EventObject evt)

Description copied from interface: Layer

The main method that performs event handling for this tool. Returns whether the event should be propagated to other layers down stream (further down the layer stack) after the event has been handled.

Specified by:

handleEvent in interface Layer

Overrides:

handleEvent in class BasicLayer

render

public long render(java.awt.Graphics2D g)

Description copied from interface: Layer

Renders the layer contents to the given Graphics.

Specified by:

render in interface Layer

Overrides:

render in class BasicLayer

Parameters:

g - the graphics object

Returns:

the rendering time in milliseconds.

setShape

public void setShape(java.awt.Shape zoomBox)

Description copied from interface: ShapeDrawingLayer

Sets the shape to be drawn

Specified by:

setShape in interface ShapeDrawingLayer

shapeCompleted

public void shapeCompleted(java.awt.event.MouseEvent e)

Description copied from interface: ShapeDrawingLayer

To be called when the shape is completely drawn

Specified by:

shapeCompleted in interface ShapeDrawingLayer

getSnapPoint

public java.awt.geom.Point2D getSnapPoint(java.awt.geom.Point2D point)

Description copied from interface: ShapeDrawingLayer

Gets the shape snap point closest to the given point

Specified by:

getSnapPoint in interface ShapeDrawingLayer

Returns:

setSliderEnabled

public void setSliderEnabled(boolean enabled)

getSliderEnabled

public boolean getSliderEnabled()

setNumTicks

public void setNumTicks(int numTicks)
