如何把一个进度指示器 [英] How to wire up a progress indicator

问题描述

我有一个圆形的进度指示器。我想这个进度条添加到应用程序我工作，但不知道如何正确连接起来。

I have a circular progress indicator. I'd like to add this progress bar to an application I'm working on but don't know how to wire it up correctly.

在我的应用程序，我想打的进程按钮，并具有同时处理数据时显示进度条。当处理完成后，我想了进度条隐藏。

In my app, I want to hit the "Process" button and have the progress bar displayed while the data is being processed. When the processing is complete, I want the progress bar to hide.

我不希望发生加工后的进度栏被隐藏。我想在进度条的数据处理同时运行（如进度条应该工作）。我不记得的步骤，但在一个点上这个正在发生的事情。

I don't want the processing to occur AFTER the progress bar is hidden. I want the progress bar to run concurrently with the data processing (like a progress bar should work). I don't remember the steps but at one point this was happening.

什么是我需要做什么？你能推荐和展示如何实现一个进度条简单的例子？

What do I need to do? Can you recommend and simple examples that show how to implement a progress bar?

推荐答案

这是什么的 BackgroundWorker的类制成的。在文档中的例子显示一个长期运行的工作线程，报告进展情况并更新UI上的进度条。

This is what the BackgroundWorker class is made for. The example in the documentation shows a long running work thread, which reports progress and updates a progress bar on the UI.
