WorldWindow.requestRedraw介绍

[英]Request that this WorldWindow update its display. Prior changes to this WorldWindow's Navigator, Globe and Layers (including the contents of layers) are reflected on screen sometime after calling this method. May be called from any thread.
[中]请求此WorldWindow更新其显示。调用此方法后，之前对此WorldWindow的导航器、全局和层（包括层的内容）所做的更改会反映在屏幕上。可以从任何线程调用。
