| Pacchetto | mx.managers |
| Classe | public class CursorManager |
| Ereditarietà | CursorManager  Object |
| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
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.

hideCursor | () | metodo |
public static function hideCursor():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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 | () | metodo |
public static function removeAllCursors():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Removes all of the cursors from the cursor list and restores the system cursor.
removeBusyCursor | () | metodo |
public static function removeBusyCursor():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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 | () | metodo |
public static function removeCursor(cursorID:int):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
cursorID:int — ID of cursor to remove.
|
setBusyCursor | () | metodo |
public static function setBusyCursor():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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 | () | metodo |
public static function setCursor(cursorClass:Class, priority:int = 2, xOffset:Number = 0, yOffset:Number = 0):int| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
cursorClass:Class — Class of the cursor to display.
| |
priority:int (default = 2)CursorManagerPriority.HIGH,
CursorManagerPriority.MEDIUM, and CursorManagerPriority.LOW.
| |
xOffset:Number (default = 0) | |
yOffset:Number (default = 0) |
int — The ID of the cursor.
