Canvas.getCaret介绍

[英]Returns the caret.

The caret for the control is automatically hidden and shown when the control is painted or resized, when focus is gained or lost and when an the control is scrolled. To avoid drawing on top of the caret, the programmer must hide and show the caret when drawing in the window any other time.
[中]返回插入符号。
当绘制或调整控件大小、获得或丢失焦点以及滚动控件时，控件的插入符号将自动隐藏和显示。为了避免在插入符号的顶部绘制，程序员必须在任何其他时间在窗口中绘制时隐藏和显示插入符号。
