显示等待光标？

我想在我正在编写的 Prism 应用程序中的耗时过程中显示等待光标。我已使用 WaitCursorRequestEvent 复合事件将其连接起来。 'True' 表示显示等待光标，'false' 表示返回默认值。

Shell 订阅事件并使用以下事件处理程序处理它：

/// <summary>
/// Handles the WaitCursorRequest event.
/// </summary>
public void OnWaitCursorRequest(bool showWaitCursor)
{
    // Set cursor
    this.Cursor = showWaitCursor ? Cursors.Wait : Cursors.Arrow;
    this.ForceCursor = true;
}

执行耗时进程的模块在启动进程时使用“true”有效负载发布事件，并使用“false”有效负载再次发布事件当它完成该过程时。

事件处理程序在这两种情况下都被调用——我通过设置断点进行了测试。但光标没有改变。知道我做错了什么吗？谢谢。

I want to show a wait cursor during a time-consuming process in a Prism app I am writing. I have wired it up using a WaitCursorRequestEvent<bool> composite event. 'True' means show the wait cursor, 'false' means go back to default.

The Shell subscribes to the event and processes it using the following event handler:

/// <summary>
/// Handles the WaitCursorRequest event.
/// </summary>
public void OnWaitCursorRequest(bool showWaitCursor)
{
    // Set cursor
    this.Cursor = showWaitCursor ? Cursors.Wait : Cursors.Arrow;
    this.ForceCursor = true;
}

The module that executes the time-consuming process publishes the event with a 'true' payload when it starts the process, and publishes the event again with a 'false' payload when it completes the process.

The event handler is being called on both occasions--I tested by setting a breakpoint. But the cursor isn't changing. Any idea what I am doing wrong? Thanks.
