Constructor Detail

Applet1

public Applet1()

Method Detail

init

public void init()

Initializes this Applet.

Applets typically use init() instead of their usual constructors for creating Components.

Overrides:

init in class SeismicDesignExerciseApplet

createAndLayoutDisplayComponents

private void createAndLayoutDisplayComponents()

Creates and places the components used to display the static values received into this exercise from previous exercises.

addInfoLabel

private void addInfoLabel(Container panel,
                          GridBagLayout gridbag,
                          GridBagConstraints constraints,
                          Component label,
                          Component value)

Helper method to allow createAndLayoutDisplayComponents() to use a GridBagLayout, which is a nasty mess.

This method adds two Label Components to a panel as a row in the GridBagLayout.

createAndLayoutInputComponents

private void createAndLayoutInputComponents()

Creates and places Components used for receiving parameter inputs from the human.

createAndLayoutViewerComponents

private void createAndLayoutViewerComponents()

Creates and places Components used for viewing the swath image, including the "depth" buttons and zoom in/out buttons.

verifyInputParameters

protected String verifyInputParameters()

This method is called so that subclasses may verify that all their required parameters have been set.

If this exercise (Applet) requires parameters to be set by previous exercises, then that will be validated here. Parameters are set in the UserParameters Object which can be retrieved by the getParameters() method.

Returns:

a message explaining which parameters must be set, or null if all required parameters are loaded.

Overrides:

verifyInputParameters in class SeismicDesignExerciseApplet

See Also:

SeismicDesignExerciseApplet.getParameters()

setInitialParameters

protected void setInitialParameters()

Sets initial parameters for this exercise.

Initial parameter values are usually based on input parameters which have been set in previous exercises. When this method is called, verifyInputParameters() has already been called, so all required input parameters can be assumed present.

Overrides:

setInitialParameters in class SeismicDesignExerciseApplet

See Also:

verifyInputParameters()

initSpinBox

private static void initSpinBox(NumericSpinner spinbox,
                                int from,
                                int to,
                                int by,
                                int initialValue)

Convenience method for initializing a Symantec spinner.

Parameters:

spinbox - the Symantec spin box to initialize

from - the minimum value for the spinner

to - the maximum value for the spinner

by - the increment for the spinner

initialValue - the value to set for the spinner

getSwathImageURLs

private String[] getSwathImageURLs()

Returns the URLs to be used to access the eight surface images for each depth.

The URLs for the eight images should be placed in the HTML for this applet in this form:

 
    
    
    ...
 
 

propertyChange

public void propertyChange(PropertyChangeEvent event)

This method is public as an implementation side-effect.

Called when a spin box is modified.

Specified by:

propertyChange in interface PropertyChangeListener

actionPerformed

public void actionPerformed(ActionEvent event)

This method is public as an implementation side-effect.

Called when a button is pushed.

Specified by:

actionPerformed in interface ActionListener

getPostURL

protected java.net.URL getPostURL()
                           throws java.net.MalformedURLException

Returns the URL to submit this applet's parameters to the server.

The URL is probably actually an HTTP GET request, with the parameters attached as query arguments.

Overrides:

getPostURL in class SeismicDesignExerciseApplet
