java – Eclipse插件 – 在Eclipse中打开编辑器时的通知

Have your class implement 07001.
Then you get notified when a workbench part (an IEditorPart,etc.) just got opened/closed. You can actually filter out which parts you want to pay attention to.

(注意：从3.5开始,IPartListener2还可以实现IPageChangedListener,以通知有关实现IPageChangeProvider和发布PageChangedEvents的任何部分.)

The tricky part (no pun intended) is to register the listener to workbench.

So,the first thing to do is get a valid IWorkbenchPage so that you can call IWorkbenchPage.addPartListener(<your class that implements IPartListener>).

以下是如何获取工作台页面.

IWorkbenchPage page = null;
IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (window != null)
{
    page = window.getActivePage();
}

if (page == null)
{
    // Look for a window and get the page off it!
    IWorkbenchWindow[] windows = PlatformUI.getWorkbench().getWorkbenchWindows();
    for (int i = 0; i < windows.length; i++)
    {
        if (windows[i] != null)
        {
            window = windows[i];
            page = windows[i].getActivePage();
            if (page != null)
            break;
        }
    }
}

另见here.

以this class为例

IPartListener2 partlistener = new IPartListener2(){
        public void partActivated( IWorkbenchPartReference partRef ) {
            if (partRef.getPart(false) == MapEditor.this){
                registerFeatureFlasher();
                ApplicationGIS.getToolManager().setCurrentEditor(editor);
            }
        }
 [...]

或者这个通用PartListener用于PartListener2的一般用法.

或者这个EditorTracker
