Method Details

canStartZoomArea

public boolean canStartZoomArea(MouseEvent mouseEvent)

Description copied from interface: Zoomable

Can a zoom area be started ?

This is called from the zoomer when a zoom area is about to start to check that there are not reasons for not starting the area. For instance if some other mouse event is to take priority over the zoom, e.g. clicking on a detection which might initiate some other menu action.

Returns:

true if zooming can start

zoomShapeChanging

public void zoomShapeChanging(ZoomShape zoomShape)

Description copied from interface: Zoomable

Called as the zoom shape changes via some sort of mouse action.

Parameters:

zoomShape - shape that's changing.

isComplete

public boolean isComplete()

Specified by:

isComplete in class AbstractTDZoomable

setComplete

public void setComplete(boolean complete)

zoomPolygonComplete

public void zoomPolygonComplete(ZoomShape zoomShape)

Description copied from interface: Zoomable

Called when a zoom shape has been completed.

Parameters:

zoomShape - zoom shape that's completed.

getXStart

public double getXStart()

Returns:

start (left most) value on the x axis scale

getXScale

public double getXScale()

Returns:

x scale in pixels per unit

getXRange

public double getXRange()

Returns:

range of x axis

getYStart

public double getYStart()

Returns:

start (bottom most) value on the y axis scale

getYScale

public double getYScale()

Returns:

y scale in pixels per unit

getYRange

public double getYRange()

Returns:

the range of the y axis

getCoordinateType

public int getCoordinateType()

Returns:

the coordinate type - can be pretty much anything so long as it is unique for different types of coordinate for that display, e.g. the Click bearing time display so that zooming can only take place in that coordinate system.

zoomToShape

public void zoomToShape(ZoomShape zoomShape)

Description copied from interface: Zoomable

Zoom to the bounds of a particular shape.

Parameters:

zoomShape - shape to zoom to

canClearZoomShape

public boolean canClearZoomShape(MouseEvent mouseEvent)

Returns:
