Mouse input
Drag-and-drop in AIR
In Adobe AIR, you can enable drag-and-drop support to allow users to drag data into and out of your application. For
more details, see “Drag and drop in AIR” on page 607.
Customizing the mouse cursor
Flash Player 9 and later, Adobe AIR 1.0 and later
The mouse cursor (mouse pointer) can be hidden or swapped for any display object on the Stage. To hide the mouse
cursor, call the Mouse.hide() method. Customize the cursor by calling Mouse.hide(), listening to the Stage for the
MouseEvent.MOUSE_MOVE event, and setting the coordinates of a display object (your custom cursor) to the stageX
and stageY properties of the event. The following example illustrates a basic execution of this task:
var cursor:Sprite = new Sprite();
cursor.graphics.beginFill(0x000000);
cursor.graphics.drawCircle(0,0,20);
cursor.graphics.endFill();
addChild(cursor);
stage.addEventListener(MouseEvent.MOUSE_MOVE,redrawCursor);
Mouse.hide();
function redrawCursor(event:MouseEvent):void
{
cursor.x = event.stageX;
cursor.y = event.stageY;
}
Mouse input example: WordSearch
Flash Player 9 and later, Adobe AIR 1.0 and later
This example demonstrates user interaction by handling mouse events. Users build as many words as possible from a
random grid of letters, spelling by moving horizontally or vertically in the grid, but never using the same letter
twice.This example demonstrates the following features of ActionScript 3.0:
Building a grid of components dynamically
Responding to mouse events
Maintaining a score based on user interaction
