progress bar

基本解釋

Consider the thread defined in Listing 10, which updates the label, progress bar and the slider in Figure 4.
考慮一下清單 10 中定義的線程，該線程將更新圖 4 中的標(biāo)簽、進度條和滑塊。
If the progress bar is visible, it means that the project build is in progress and you must wait for it to finish.
如果進度條可見的話，那么這就意味著項目構(gòu)建正在進行當(dāng)中，而您必須等到它完成為止。
While a thread is running, either uploading or downloading, you can query it to check on its status to provide the user with feedback (eg. a progress bar).
當(dāng)一個線程在運行的時候，不管是上傳還是下載，你可以查詢進程狀態(tài)并且給用戶一個反饋（例如一個進度條）。

A progress bar is not supposed to print one hundred lines just to update its status; generally we like to see a little animation.
一個進度條不應(yīng)該是打印100行,只是更新它的狀態(tài)，一般地，我們,想看到一點生機。
