getActiveWorkbenchWindow() return null 解決辦法

標籤：class   blog   c   code   java   a   

getActiveWorkbenchWindow 有如下聲明

/** * Returns the currently active window for this workbench (if any). Returns * <code>null</code> if there is no active workbench window. Returns * <code>null</code> if called from a non-UI thread. *  * @return the active workbench window, or <code>null</code> if there is *         no active workbench window or if called from a non-UI thread */public IWorkbenchWindow getActiveWorkbenchWindow();

調調用的時候不在UI線程中，所以會返回空，可採用如下辦法解決

PlatformUI.getWorkbench().getDisplay().asyncExec(new Runnable() {public void run() {IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();System.out.println(window);//做想要做的事情吧。}});
