ProjectがCloseされたら関連Resourceを開いているEditorを閉じる方法

EclipsePlugin

久々にプラグインネタ。最近Jiemamyもまた触り始めたので。

本日、長い間解決していなかったバグが一つ潰れました。

EclipseのResource（EclipseのPackageExplorer等に評じされるワークスペース内のファイル等）は、いずれかのProjectに属していますね。で、そのResourceをエディタで開いている状態を考えます。

この状態のまま、Projectをクローズ（コンテキストメニューからCloseProjectを選択）した場合、開いているResourceがdirty（編集済み未保存）の場合はSaveを促してから自動で閉じ、そうでなければ自動的にエディタを閉じるべきです。

JavaエディタやTextエディタなど、そういった仕様になっています。しかし、Jiemamyのダイアグラムエディタではエディタがそのまま残ってしまい、クローズした後に保存しようとするとResourceExceptionが飛ぶ状態になっていました。

  • TextEditor（org.eclipse.ui.editors.text）
  • JavaEditor（org.eclipse.jdt.internal.ui.javaeditor）

代表的な上記エディタの実装を参考に、ちゃんと閉じるように実装してみようと思ったのですが、なぜちゃんと閉じるのかが分かりませんでした。（いや、今もよくわかりませんｗ）

半年以上わからない状態が続いた為、たけぞうさんに神頼み。解決へのヒントを頂きました。ありがとうございます！ （この件、ブログに掲載することも快くOKを頂きました。重ね重ね感謝です。）

public void resourceChanged(final IResourceChangeEvent event)
でクローズされたとか取れないですかね。

StrutsIDEなどでファイルが削除された場合にエディタを閉じるといった処理を上記のメソッドで行った記憶があります。

なるほど。というわけで、早速DiagramEditorにorg.eclipse.core.resources.IResourceChangeListenerをimplementsし、コンストラクタで自らをリスナ登録しました。

さらにdisposeメソッド内でリスナを削除する処理も追記。

IResourceChangeListener#resourceChanged(...) の実装はちょっと心配だったので、StrutsIDEのコードを参考にさせて頂きました。

public class DiagramEditor extends GraphicalEditorWithFlyoutPalette
    implements IResourceChangeListener {

  public DiagramEditor() {
    ...
    ResourcesPlugin.getWorkspace().addResourceChangeListener(this);
  }

  @Override
  public void dispose() {
    ResourcesPlugin.getWorkspace().removeResourceChangeListener(this);
    super.dispose();
  }

  public void resourceChanged(final IResourceChangeEvent event) {
    if (event.getType() == IResourceChangeEvent.POST_CHANGE) {
      final IEditorInput input = getEditorInput();
      if (input instanceof IFileEditorInput) {
        Display.getDefault().asyncExec(new Runnable() {
          
          public void run() {
            IFile file = ((IFileEditorInput) input).getFile();
            if (!file.exists()) {
              IWorkbenchPage page =
                  PlatformUI.getWorkbench()
                    .getActiveWorkbenchWindow()
                    .getActivePage();
              page.closeEditor(DiagramEditor.this, true);
            } else if (!getPartName().equals(file.getName())) {
              setPartName(file.getName());
            }
          }
        });
      }
    }
  }
  ...
}

以上でProjectのクローズ対策をすることができました。

その後じっくりソースを眺め、なるほど。ここのelse if節で「開いている時にResourceのリネームがあった時、エディタのタブに表示されるファイル名も修正する」という処理も同時に出来てしまうのか。と思い、まずはお手本であるTextEditorで挙動を調べてみる。

おおお。開いていたファイルのリネームが綺麗に通った！

ということでDiagramEditorで開いているファイルをリネームしてみた訳ですが…。
