busy indicator

基本解释

You might just want to use the non-committal infinite scrolling busy indicator while you perform the query.
你可能只想当你执行查询使用非承诺无限滚动的忙闲指示器。
With RRAFS, we can also create two Image VPs--one for the busy indicator and another with an empty content--as shown in Figures 19 and 20, respectively
用 RRAFS，还可以生成两个 Image VP——一个用于占线指示器，另一个为空——如图 19 和图 20 分别所示
What I want to do is while waiting for the initialization of the usercontrol, a busy indicator will appear and will disappear when the initialization of the usercontrol is finished.
我想要做的是在等待用户控件的初始化，会出现一个繁忙的指标和用户控件的初始化完成后将会消失。
