ZoomRectangle

public ZoomRectangle(Zoomer zoomer,
             int coordindateType,
             double xStart,
             double yStart)

Method Detail

drawShape

public java.awt.Rectangle drawShape(java.awt.Graphics g,
                           java.awt.Component component,
                           boolean beforeOther)

Draw the shape using the given graphics handle on the given component.

Specified by:

drawShape in class ZoomShape

Parameters:

g - graphics

component - component to draw on

Returns:

outer bounds of drawn region (should be same as getBounds());

drawShapeOutline

public java.awt.Rectangle drawShapeOutline(java.awt.Graphics g,
                                  java.awt.Component component,
                                  java.awt.Rectangle r)

drawShapeSolid

                                java.awt.Rectangle r)

containsPoint

public boolean containsPoint(java.awt.Component component,
                    java.awt.Point pt)

Description copied from class: ZoomShape

Shape contains the point pt.

Note that these are in screen pixel coordinates.

Specified by:

removeOnZoom

public boolean removeOnZoom()

Specified by:

removeOnZoom in class ZoomShape

Returns:

true if the object should no longer be displayed after zooming

Basically true for rectangles, false for polygons.

newPoint

public void newPoint(double x,
            double y)

Description copied from class: ZoomShape

New point to add to the shape - or update old point if it's a rectangle.

Specified by:

newPoint in class ZoomShape

Parameters:

x - x coordinate in display units such as time or bearing, NOT PIXELS

y - y coordinate in display units such as time or bearing, NOT PIXELS

getBounds

Specified by:

getXStart in class ZoomShape

Returns:

the lowest x value

getYLength

public double getYLength()

Specified by:

getYLength in class ZoomShape

Returns:

the difference between the minimum and maximum y values.

getYStart

public double getYStart()

Specified by:

getYStart in class ZoomShape

Returns:

the lowest y value
