Class SampleView

java.lang.Object
  ViewPart
      ch.elexis.developer.resources.view.SampleView

All Implemented Interfaces:

GlobalEventDispatcher.IActivationListener, IPersistenceProvider

public class SampleView
extends ViewPart
implements GlobalEventDispatcher.IActivationListener, IPersistenceProvider

This is a sample view to demonstrate how to connect to elexis's event scheduler and how to display elexis's data types. We implement IActivationListener to be informed, wenn the user can see our View. All UI funktions should only be active in that case.

SampleView

public SampleView()

Method Detail

createPartControl

public void createPartControl(Composite parent)

This is the right place to create all UI elements. The parent composite already has a GridLayout.

dispose

public void dispose()

On disposal,the IActivationListener MUST be unregistered. Also, our RestrictedAction must be unregistered from the AutoAdapt queue to prevent memory leaks.

setFocus

public void setFocus()

activation

public void activation(boolean mode)

From IActivationListener: the view was activated or inactivated

Specified by:

activation in interface GlobalEventDispatcher.IActivationListener

Parameters:

mode -

visible

public void visible(boolean mode)

From IActivationListener: The View changes visibility. Our listeners need only to be active, if the view is visible. So we unregister them if the view disappears to save resources. If the view becomes visible again, we must send an event, because the listeners don't know what happend before they start listening

Specified by:

visible in interface GlobalEventDispatcher.IActivationListener

Parameters:

mode - true: the view becomes visible. false: the view becomes invisible

store

public void store(java.lang.String data,
                  java.lang.Object param)
           throws PersistenceException

Description copied from interface: IPersistenceProvider

Store data transparently to the IPersistenceProvider's backing store

Specified by:

store in interface IPersistenceProvider

Parameters:

data - the data to store. The IPersistenceProvider must be able to reconstruct the data from the String retrieved by load()

param - a implememntation dependent parameter. Can be null or any arbitrary object

Throws:

PersistenceException - if the data could not be stored correctly

See Also:

store the contents of the SimpleStructuredDocument (wich is in the BaseRichTextDisplay)

load

public java.lang.String load(java.lang.Object param)
                      throws PersistenceException

Description copied from interface: IPersistenceProvider

Load the dependent data from the backing store

Specified by:

load in interface IPersistenceProvider

Parameters:

param - an implementation depoendent parameter. Can be null or any arbitrary Object

Returns:

the data read. Must be exactly the same as written by store()

Throws:

PersistenceException - if the data coulkd not be read correctly
