在Eclipse中打开新的编辑器时，如何得到通知？ [英] How do I get notified whenever a new editor is opened in Eclipse?

问题描述

我有一个想要通知所有当前打开的编辑的视图。我在哪里可以添加一个监听器来实现这一点？

我期待WorkbenchPage或EditorManager有一些适当的监听器注册表，但我找不到它。

解决方案

您的视图是否使用 ？

这是什么使用这个 EditorListener ， >

  public class EditorListener实现ISelectionListener，IFileBufferListener，
 IPartListener2 {
 protected BytecodeOutlineView view; 
 
 EditorListener（BytecodeOutlineView view）{
 this.view = view; 
} 
 
 [...] 
 
 / ** 
 * @see org.eclipse.ui.IPartListener2＃partOpened（org.eclipse。 ui.IWorkbenchPartReference）
 * / 
 public void partOpened（IWorkbenchPartReference partRef）{
 view.handlePartVisible（partRef.getPart（false））; 
}

现在如果你的 ViewPart 直接实现一个 IPartListener2 ，它可以注册到各种编辑器，像这样 BytecodeReferenceView

  public class BytecodeReferenceView extends ViewPart实现IPartListener2，ISelectionListener {
 
 [...] 
 
 public void createPartControl（Composite parent）{
 browser = new Browser（parent，SWT.BORDER）; 
 browser.setText（BytecodeOutlinePlugin.getResourceString（NLS_PREFIX 
 +empty.selection.text））; 
 final IWorkbenchWindow workbenchWindow = getSite（）。getWorkbenchWindow（）; 
 workbenchWindow.getPartService（）。addPartListener（this）; 
 [...] 
  

I have a view which would like to be notified about all the currently opened editors. Where can I add a listener to achieve this?

I was expecting WorkbenchPage or EditorManager to have some appropriate listener registry, but I couldn't find it.

解决方案

Does your view uses a org.eclipse.ui.IPartListener2 ?

That is what is using this EditorListener, whose job is to react, for a given view, to Editor events (including open and close)

public class EditorListener implements ISelectionListener, IFileBufferListener,
IPartListener2 {
    protected BytecodeOutlineView view;

    EditorListener(BytecodeOutlineView view){
        this.view = view;
    }

[...] 

    /**
     * @see org.eclipse.ui.IPartListener2#partOpened(org.eclipse.ui.IWorkbenchPartReference)
     */
    public void partOpened(IWorkbenchPartReference partRef) {
        view.handlePartVisible(partRef.getPart(false));
    }

---

Now if your ViewPart directly implements an IPartListener2, it can register itself to the various Editors, like this BytecodeReferenceView

public class BytecodeReferenceView extends ViewPart implements IPartListener2, ISelectionListener {

    [...]

    public void createPartControl(Composite parent) {
        browser = new Browser(parent, SWT.BORDER);
        browser.setText(BytecodeOutlinePlugin.getResourceString(NLS_PREFIX
            + "empty.selection.text"));
        final IWorkbenchWindow workbenchWindow = getSite().getWorkbenchWindow();
        workbenchWindow.getPartService().addPartListener(this);
    [...]
