Selection Handling
Before we clean up our
RequirementsEditor
class, we need to fix the selec-
tion handling we disrupted by splitting up the editor.
MultiPageEditorPart
already provides a mechanism to handle selection changes, so we can refactor the
code to use it. We add a
MultiPageSelectionProvider selection
Provider
attribute to the class and initialize it in the constructor. We then set
this instance as the sitewide provider in the
init()
method, thereby eliminating
the need for the editor to implement
ISelectionProvider
. Changes are
in bold.
MultiPageSelectionProvider selectionProvider;
private int diagramPageIndex;
/**
* This creates a model editor.
*
Modified to initialize selection provider.
*
* @generated
NOT
*/
public RequirementsEditor() {
super();
initializeEditingDomain();
selectionProvider = new MultiPageSelectionProvider(this);
selectionProvider.addSelectionChangedListener(new
ISelectionChangedListener()
{
public void selectionChanged(SelectionChangedEvent event) {
setStatusLineManager(event.getSelection());
IEditorPart activeEditor = getSite().getPage().getActiveEditor();
if (selectionProvider.getMultiPageEditor().equals(activeEditor)
