InheritanceCursorManager Inheritance Object

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

The CursorManager class controls a prioritized list of cursors, where the cursor with the highest priority is currently visible. If the cursor list contains more than one cursor with the same priority, the Cursor Manager displays the most recently created cursor.

For example, if your application performs processing that requires the user to wait until the processing completes, you can change the cursor so that it reflects the waiting period. In this case, you can change the cursor to an hourglass or other image.

You also might want to change the cursor to provide feedback to the user to indicate the actions that the user can perform. For example, you can use one cursor image to indicate that user input is enabled, and another to indicate that input is disabled. You can use a JPEG, GIF, PNG, or SVG image, a Sprite object, or a SWF file as the cursor image.

All methods and properties of the CursorManager are static, so you do not need to create an instance of it.

In AIR, each mx.core.Window instance uses its own instance of the CursorManager class. Instead of directly referencing the static methods and properties of the CursorManager class, use the Window.cursorManager property to reference the CursorManager instance for the Window instance.

Method Detail
getInstance()method
public static function getInstance():ICursorManager

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Each mx.core.Window instance in an AIR application has its own CursorManager instance. This method returns the CursorManager instance for the main Window instance.

Returns
ICursorManager — The CursorManager instance for the main Window instance in an AIR application.
hideCursor()method 
public static function hideCursor():void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Makes the cursor invisible. Cursor visibility is not reference-counted. A single call to the hideCursor() method always hides the cursor regardless of how many calls to the showCursor() method were made.

Calling this method does not affect the system cursor. Use the Mouse.show() and Mouse.hide() methods to directly control the system cursor.

removeAllCursors()method 
public static function removeAllCursors():void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Removes all of the cursors from the cursor list and restores the system cursor.

removeBusyCursor()method 
public static function removeBusyCursor():void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Removes the busy cursor from the cursor list. If other busy cursor requests are still active in the cursor list, which means you called the setBusyCursor() method more than once, a busy cursor does not disappear until you remove all busy cursors from the list.

removeCursor()method 
public static function removeCursor(cursorID:int):void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Removes a cursor from the cursor list. If the cursor being removed is the currently displayed cursor, the CursorManager displays the next cursor in the list, if one exists. If the list becomes empty, the CursorManager displays the default system cursor.

Parameters

cursorID:int — ID of cursor to remove.

setBusyCursor()method 
public static function setBusyCursor():void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Displays the busy cursor. The busy cursor has a priority of CursorManagerPriority.LOW. Therefore, if the cursor list contains a cursor with a higher priority, the busy cursor is not displayed until you remove the higher priority cursor. To create a busy cursor at a higher priority level, use the setCursor() method.

setCursor()method 
public static function setCursor(cursorClass:Class, priority:int = 2, xOffset:Number = 0, yOffset:Number = 0):int

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Creates a new cursor and sets an optional priority for the cursor. Adds the new cursor to the cursor list.

Parameters

cursorClass:Class — Class of the cursor to display.
 
priority:int (default = 2) — Integer that specifies the priority level of the cursor. Possible values are CursorManagerPriority.HIGH, CursorManagerPriority.MEDIUM, and CursorManagerPriority.LOW.
 
xOffset:Number (default = 0) — Number that specifies the x offset of the cursor, in pixels, relative to the mouse pointer.
 
yOffset:Number (default = 0) — Number that specifies the y offset of the cursor, in pixels, relative to the mouse pointer.

Returns
int — The ID of the cursor.

showCursor()method 
public static function showCursor():void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Makes the cursor visible. Cursor visibility is not reference-counted. A single call to the showCursor() method always shows the cursor regardless of how many calls to the hideCursor() method were made.

Calling this method does not affect the system cursor. Use the Mouse.show() and Mouse.hide() methods to directly control the system cursor.

public static const NO_CURSOR:int = 0

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Constant that is the value of currentCursorID property when there is no cursor managed by the CursorManager and therefore the system cursor is being displayed.
