Class RegionBoundsInputUI

java.lang.Object

org.esa.snap.ui.RegionBoundsInputUI

public class RegionBoundsInputUI
extends Object

This user interface provides a world map and text fields to define region bounds. The input values from the text fields and from the world map are reflected in the BindingContext, which can be retrieved using getBindingContext().

Constructor Details

RegionBoundsInputUI

public RegionBoundsInputUI()

Initializes a RegionBoundsInputUI. This constructor creates the user interface and a binding context with default values. The created binding context can be retrieved via getBindingContext().

RegionBoundsInputUI

public RegionBoundsInputUI(double northBound,
 double eastBound,
 double southBound,
 double westBound)

Initializes a RegionBoundsInputUI with the given parameters. If the parameters are valid geographic coordinates, they are used to initialize the user interface and to create a binding context. If the values are invalid, default values will be used. The created binding context can be retrieved via getBindingContext().

Parameters:

northBound - The northern bounding latitude value

eastBound - The eastern bound longitude value

southBound - The southern bound latitude value

westBound - The western bound longitude value

RegionBoundsInputUI

public RegionBoundsInputUI(com.bc.ceres.swing.binding.BindingContext bindingContext)

Initializes a RegionBoundsInputUI with the given bindingContext. The bindingContext has to contain four parameters: northBound , southBound, westBound and eastBound. If the bindingContext contains geographic coordinates, these coordinates are used to initialize the user interface.

Parameters:

bindingContext - The binding context which is needed for initialisation.

Method Details

setEnabled

public void setEnabled(boolean enabled)

Enables or disables all child components.

Parameters:

enabled - -

getUI

public JPanel getUI()

Returns:

a JPanel which contains the user interface elements

getBindingContext

public com.bc.ceres.swing.binding.BindingContext getBindingContext()

Returns the binding context which contains property values northBound , southBound, westBound, and eastBound. This method should be used to get the bounds set by the UI components. It is needed when no binding context has been passed to the RegionBoundsInputUI initially.

Returns:

the binding context.
