1、帮助文件中对DeskTopRectList的解释：
System property; displays the size and position on the desktop of the monitors connected to a computer. Read-only.

This property is useful for checking whether objects such as windows, sprites, and pop-up windows appear entirely on one screen.

The result is a list of rectangles, where each rectangle is the boundary of a monitor. The coordinates for each monitor are relative to the upper left corner of monitor 1, which has the value (0,0). The first set of rectangle coordinates is the size of the first monitor. If a second monitor is present, a second set of coordinates shows where the corners of the second monitor are relative to the first monitor.

中文翻译如下：
系统属性；显示在桌面上的尺寸和位置。这个属性对检查对象(例如窗口，精灵，弹出窗口)是否完全显示在屏幕上很有用。 结果是一个rectangles格式的表，每个rectangle表示一个显示器的边界的坐标。每个监视器的坐标以第一个监视器的左上角为坐标0点。第一个监视器的坐标
等于它的尺寸。如果有第二个监视器，则第二个rectagle值显示第二监视器的右下角相对于第一个监视器的位置。本属性可以测试，但不能设置。
