PopUpManager

Package | mx.managers
Class | public class PopUpManager
Inheritance | PopUpManager Object

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

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.

Method Detail

addPopUp | () | 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.

Parameters

| `window:IFlexDisplayObject` — The IFlexDisplayObject to be popped up.
| `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.

`public static function bringToFront(popUp:IFlexDisplayObject):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Parameters

centerPopUp | () | method |

`public static function centerPopUp(popUp:IFlexDisplayObject):void`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

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.

Parameters

| `popUp:IFlexDisplayObject` — IFlexDisplayObject representing the popup.

createPopUp | () | method |

`public static function createPopUp(parent:DisplayObject, className:Class, modal:Boolean = false, childList:String = null, moduleFactory:IFlexModuleFactory = null):IFlexDisplayObject`

Language Version : | ActionScript 3.0

Runtime Versions : | Flash Player 9, AIR 1.1

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.

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).
