Creating a pop-up window

To create a pop-up window, use the PopUpManager createPopUp() method. The createPopUp() method has the following signature:

public static createPopUp(parent:DisplayObject, class:Class,
modal:Boolean = false):IFlexDisplayObject
The method has the following arguments.
Argument
Description

parent
A reference to a window to pop-up over.

class
A reference to the class of object you want to create, typically a custom MXML component that implements a TitleWindow container.

modal
(Optional) A Boolean value that indicates whether the window is modal, and takes all mouse input until it is closed (true), or whether interaction is allowed with other controls while the window is displayed (false). The default value is false.

我们通过(p1.width-login.width)/2和(p1.height-login.height)/2实现弹出窗口的居中!

PopUpManager.createPopUp( this, Win2 , true)　参数：父显示对象，要显示的对象，是否为模态窗口;
