Constructor Detail

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)

Description copied from class: ZoomShape

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());

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:

containsPoint in class ZoomShape

pt - point

Returns:

true if the point is within the shape.

closeShape

public void closeShape()

Description copied from class: ZoomShape

Shape is complete for whatever reason.

Overrides:

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

public java.awt.Rectangle getBounds(java.awt.Component component)

Specified by:

getBounds in class ZoomShape

Returns:

the outer bounds of the zoom shape in pixels.

getXLength

public double getXLength()

Specified by:

getXLength in class ZoomShape

Returns:

the difference between the minimum and maximum x values.

getXStart

public double getXStart()

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
