The PopUpManager singleton class creates new top-level windows and
places or removes those windows from the layer on top of all other
visible windows. See the SystemManager for a description of the layering.
It is used for popup dialogs, menus, and dropdowns in the ComboBox control
and in similar components.
The PopUpManager also provides modality, so that windows below the popup
cannot receive mouse events, and also provides an event if the user clicks
the mouse outside the window so the developer can choose to dismiss
the window or warn the user.

Makes sure a popup window is higher than other objects in its child list
The SystemManager does this automatically if the popup is a top level window
and is moused on,
but otherwise you have to take care of this yourself.

Removes a popup window popped up by
the createPopUp() or addPopUp() method.

method
public static function addPopUp(window:IFlexDisplayObject, parent:DisplayObject, modal:Boolean = false, childList:String = null, moduleFactory:IFlexModuleFactory = null):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Pops up a top-level window.
It is good practice to call removePopUp() to remove popups
created by using the addPopUp() method.
If the class implements IFocusManagerContainer, the window will have its
own FocusManager so that, if the user uses the TAB key to navigate between
controls, only the controls in the window will be accessed.
Example
var tw:TitleWindow = new TitleWindow();
tw.title = "My Title";
mx.managers.PopUpManager.addPopUp(tw, pnl, false);
Creates a popup window using the tw instance of the
TitleWindow class and pnl as the Sprite for determining
where to place the popup.
It is defined to be a non-modal window.
parent:DisplayObject — DisplayObject to be used for determining which SystemManager's layers
to use and optionally the reference point for centering the new
top level window. It may not be the actual parent of the popup as all popups
are parented by the SystemManager.
modal:Boolean (default = false) — If true, the window is modal which means that
the user will not be able to interact with other popups until the window
is removed.
childList:String (default = null) — The child list in which to add the pop-up.
One of PopUpManagerChildList.APPLICATION,
PopUpManagerChildList.POPUP,
or PopUpManagerChildList.PARENT (default).
moduleFactory:IFlexModuleFactory (default = null) — The moduleFactory where this pop-up should look for
its embedded fonts and style manager.

Centers a popup window over whatever window was used in the call
to the createPopUp() or addPopUp() method.
Note that the position of the popup window may not
change immediately after this call since Flex may wait to measure and layout the
popup window before centering it.

Creates a top-level window and places it above other windows in the
z-order.
It is good practice to call the removePopUp() method
to remove popups created by using the createPopUp() method.
If the class implements IFocusManagerContainer, the window will have its
own FocusManager so that, if the user uses the TAB key to navigate between
controls, only the controls in the window will be accessed.
Example
pop = mx.managers.PopUpManager.createPopUp(pnl, TitleWindow, false);
Creates a popup window based on the TitleWindow class, using pnl as the MovieClip
for determining where to place the popup. It is defined to be a non-modal window
meaning that other windows can receive mouse events
Parameters
parent:DisplayObject — DisplayObject to be used for determining which SystemManager's layers
to use and optionally the reference point for centering the new
top level window. It may not be the actual parent of the popup as all popups
are parented by the SystemManager.
className:Class — Class of object that is to be created for the popup.
The class must implement IFlexDisplayObject.
modal:Boolean (default = false) — If true, the window is modal which means that
the user will not be able to interact with other popups until the window
is removed.
childList:String (default = null) — The child list in which to add the popup.
One of PopUpManagerChildList.APPLICATION,
PopUpManagerChildList.POPUP,
or PopUpManagerChildList.PARENT (default).
moduleFactory:IFlexModuleFactory (default = null) — The moduleFactory where this pop-up should look for
its embedded fonts and style manager.
