GC.drawFocus介绍

[英]Draws a rectangle, based on the specified arguments, which has the appearance of the platform's focus rectangle if the platform supports such a notion, and otherwise draws a simple rectangle in the receiver's foreground color.
[中]基于指定的参数绘制一个矩形，如果平台支持这样的概念，则该矩形具有平台的焦点矩形的外观，否则在接收器的前景色中绘制一个简单的矩形。
