Hi all,
I created an action subclassing SelectionAction, I must use the method
getSelectedObjects to perform my action, the problem is:
getSelectedObjects() returns the correct list when used in the
"calculateEnabled" method , but when I use it in the "run" method (clicking
the action's button in the toolbar) it returns an empty list.
So when I select objects in my editor and then click to perform my action it
does nothing because it doesn't have objects to work on.
Thanks in advance,
Paolo.
P.S.
Here's some code snippets:
MY ACTION CLASS
public class AllineaSinistraAction extends SelectionAction {
static public String
ID="com.pr.deserver.editors.AllineaSinistraAction";
static public String TEXT="Allinea a sinistra";
static public String TOOLTIP="Allinea a sinistra i controlli
selezionati";
public AllineaSinistraAction(IWorkbenchPart part) {
super(part);
setLazyEnablementCalculation(false);
setId(AllineaSinistraAction.ID);
}
public void run()
{
System.out.println(getSelectedObjects()); -- just to see that
selected objets' list is empty
}
protected boolean calculateEnabled() {
return getSelectedObjects().size()>1; -- here the list is
not empty
}
}
MY EDITOR CLASS
public class DeServerEditor extends GraphicalEditorWithFlyoutPalette
implements CommandStackListener,
ISelectionListener{
....
protected void createActions() {
super.createActions();
ActionRegistry registry = getActionRegistry();
IAction action;
action = new AllineaSinistraAction((IWorkbenchPart) this);
registry.registerAction(action);
getSelectionActions().add(action.getId());
}
....
}
MY EDITOR CONTRIBUTOR CLASS
public class DeServerEditorContributor extends ActionBarContributor {
private IEditorPart m_editor;
private AllineaSinistraAction m_allineaSinistra;
....
protected void buildActions() {
addRetargetAction(new UndoRetargetAction());
addRetargetAction(new RedoRetargetAction());
addRetargetAction(new DeleteRetargetAction());
buildAlignmentActions();
addAction(m_allineaSinistra);
}
private void buildAlignmentActions() {
m_allineaSinistra=new AllineaSinistraAction(m_editor);
m_allineaSinistra.setToolTipText("Allinea a sinistra");
m_allineaSinistra.setId("com.pr.deserver.editors.AllineaSinistrAction ");
m_allineaSinistra.setImageDescriptor(create("icons/", "left_align.gif"));
}
....
}

I' ve noticed that, when the run() method is called , the almost all the
member of my action class are null:
It's not the same when the calculateEnabled() is called (they are not null)
Thanks.
