Eclipse：如何以编程方式打开编辑器

问题描述：

我想知道如何以编程方式打开编辑器。我首先创建了适当的文件，然后要打开此文件类型的编辑器。但是我当时无法打开编辑器。

I'm wondering how I can open an editor programmatically. I first created the appropriated file and then I want to open the editor for this type of file. But I'm not able to open the editor then.

...
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
PlcEditor editor = new PlcEditor(emfResource);
page.openEditor(editor, "test");
...

我已经有以下解决方案（有效），但是在这里无法调用我的编辑器的构造函数：

I already had the following solution (which works), but here I wasn't able to call the constructr of my editor:

....
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IEditorPart openEditor = IDE.openEditor(page, plcFile);
....

答

首先，您必须使用 org.eclipse.ui.editors 扩展点将您的编辑器定义为Eclipse：

First you must define your editor to Eclipse using the org.eclipse.ui.editors extension point:

<extension
     point="org.eclipse.ui.editors">
  <editor
        name="Sample Multi-page Editor"
        extensions="mpe"
        icon="icons/sample.gif"
        contributorClass="tested.editors.MultiPageEditorContributor"
        class="tested.editors.MultiPageEditor"
        id="tested.editors.MultiPageEditor">
  </editor>
</extension>

（以上由提供的多页编辑器示例创建）。

(above is as created by the provided multi-page editor example).

然后可以使用：

IDE.openEditor(page, file, "tested.editors.MultiPageEditor");

在 IFile 上打开编辑器您的编辑器ID，或为扩展名指定的编辑器将是默认值，您可以使用

to open the editor on an IFile specifying your editor id, or for the extension specified the editor will be the default and you can just use

IDE.openEditor(page, file);

您还可以使用 contentTypeBinding 子元素编辑器来指定内容类型，然后编辑器将处理。

You can also use the contentTypeBinding child element of editor to specify content types then editor will handle.
