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

问题描述

我有一个视图希望收到所有当前打开的编辑器的通知.我在哪里可以添加监听器来实现这一点?

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?

我希望 WorkbenchPage 或 EditorManager 有一些合适的监听器注册表，但我找不到它.

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

推荐答案

您的视图是否使用 org.eclipse.ui.IPartListener2 ?

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

这就是使用这个 EditorListener，其工作是针对给定视图对编辑器事件(包括打开和关闭)做出反应

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));
    }

现在，如果您的 ViewPart 直接实现 IPartListener2，它可以将自己注册到各种 Editors，就像这样 BytecodeReferenceView

---

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);
    [...]
