类名称：GC
方法名：textExtent

GC.textExtent介绍

[英]Returns the extent of the given string. Tab expansion and carriage return processing are performed.

The extent of a string is the width and height of the rectangular area it would cover if drawn in a particular font (in this case, the current font in the receiver).
[中]返回给定字符串的范围。执行选项卡展开和回车处理。
字符串的范围是以特定字体绘制时将覆盖的矩形区域的宽度和高度（在本例中为接收器中的当前字体）。
