如何在基于 Eclipse 的应用程序中将按键重定向到另一个 shell？

我正在研究一种方法，使基于 Eclipse 的 RCP 应用程序中的 EditorPart 最大化，使其完全全屏、无修剪、无菜单等。实际上，它是 GEF 编辑器。这有点像黑客，但它确实有效：

GraphicalViewer viewer = (GraphicalViewer)getWorkbenchPart().getAdapter(GraphicalViewer.class);
        Control control = viewer.getControl();
        Composite oldParent = control.getParent();

        Shell shell = new Shell(SWT.APPLICATION_MODAL);
        shell.setFullScreen(true);
        shell.setMaximized(true);

        // Some code here to listen to Esc key to dispose Shell and return...

        shell.setLayout(new FillLayout());
        control.setParent(shell);
        shell.open();

基本上它将 GraphicalViewer 控件的父级设置为新创建的最大化的 Shell。按 escape 会将控件返回到其原始父级（为简洁起见，未显示代码）。

唯一不起作用的是接收全局按键（Del、Ctrl+Z、Ctrl+ A）为工作台声明并转发到 EditorPart 的那些。有什么方法可以连接到这些或将它们从 EditorPart 重定向到将它们转发到 GraphicalViewer 吗？

提前致谢

I'm working on a way to maximise an EditorPart in my Eclipse-based RCP app to be absolutely full-screen, no trim, no menu, and so on. Actually, it's a GEF Editor. It's a bit of a hack, but it kind of works:

GraphicalViewer viewer = (GraphicalViewer)getWorkbenchPart().getAdapter(GraphicalViewer.class);
        Control control = viewer.getControl();
        Composite oldParent = control.getParent();

        Shell shell = new Shell(SWT.APPLICATION_MODAL);
        shell.setFullScreen(true);
        shell.setMaximized(true);

        // Some code here to listen to Esc key to dispose Shell and return...

        shell.setLayout(new FillLayout());
        control.setParent(shell);
        shell.open();

Basically it sets the parent of the GraphicalViewer control to the newly created, maximised Shell. Pressing escape will return the control to it's original parent (code not shown for brevity).

The only thing that doesn't work is receiving global key presses (Del, Ctrl+Z, Ctrl+A) the ones that are declared for the Workbench and forwarded to the EditorPart. Is there any way I can hook into these or redirect them from the EditorPart to forward them on to the GraphicalViewer?

Thanks in advance

简短的回答是你不能这样做。一旦您将该组合重新设置为工作台窗口之外的父级，它就完全崩溃了。系统无法正确处理该部件，因为事件（如激活、焦点、setBounds(*)）未被处理。

唯一受支持的方法是打开一个新的 Workbench 窗口，其中的透视图仅包含编辑器区域，并为该窗口扩展 org.eclipse.ui.application.WorkbenchWindowAdvisor.createWindowContents(Shell) 方法+透视组合，使用 org.eclipse.ui.application.IWorkbenchWindowConfigurer 隐藏所有不需要的修剪。

例如，在 MyWorkbenchWindowAdvisor 中：

public void createWindowContents(Shell shell) {
    if (isCreatingSpecialPerspective()) {
        final IWorkbenchWindowConfigurer config = getWindowConfigurer();
        config.setShowCoolBar(false);
        config.setShowFastViewBars(false);
        config.setShowMenuBar(false);
        config.setShowPerspectiveBar(false);
        config.setShowProgressIndicator(false);
        config.setShowStatusLine(false);
    }
    super.createWindowContents(shell);
}

另请查看 http://code.google.com/p/eclipse- fullscreen/ 其中包含 EPLed 代码，涉及运行具有全屏支持的 RCP 程序。

The short answer is you can't do that. Once you re-parent that composite out of the workbench window, it's totally busted. The system won't correctly deal with the part, as events (like activation, focus, setBounds(*)) aren't being processed.

The only supported way would be to open a new Workbench window with a perspective that only contained the editor area, and extending your org.eclipse.ui.application.WorkbenchWindowAdvisor.createWindowContents(Shell) method for that window+perspective combination to hide all of the trim you don't want, using org.eclipse.ui.application.IWorkbenchWindowConfigurer.

ex, in MyWorkbenchWindowAdvisor:

public void createWindowContents(Shell shell) {
    if (isCreatingSpecialPerspective()) {
        final IWorkbenchWindowConfigurer config = getWindowConfigurer();
        config.setShowCoolBar(false);
        config.setShowFastViewBars(false);
        config.setShowMenuBar(false);
        config.setShowPerspectiveBar(false);
        config.setShowProgressIndicator(false);
        config.setShowStatusLine(false);
    }
    super.createWindowContents(shell);
}

Also check out http://code.google.com/p/eclipse-fullscreen/ which has EPLed code in it concerned with running an RCP program with fullscreen support.
