onMouseUp (Mouse.onMouseUp event listener)
onMouseUp = function() {}
Notified when the mouse is released. To use the
onMouseUp
listener, you must create a listener
object. You can then define a function for
onMouseUp
and use
addListener()
to register the
listener with the Mouse object, as shown in the following code:
var someListener:Object = new Object();
someListener.onMouseUp = function () { ... };
Mouse.addListener(someListener);
Listeners enable different pieces of code to cooperate because multiple listeners can receive
notification about a single event.
A Flash application can only monitor mouse events that occur within its focus. A Flash
application cannot detect mouse events in another application.
Availability:
ActionScript 1.0; Flash Player 6
Example
The following example uses the mouse pointer as a tool to draw lines using
onMouseMove
and
the Drawing API. The user draws a line when they drag the mouse pointer. The user stops
drawing the line when they release the mouse button.
this.createEmptyMovieClip("canvas_mc", this.getNextHighestDepth());
var mouseListener:Object = new Object();
mouseListener.onMouseDown = function() {
this.isDrawing = true;
canvas_mc.lineStyle(2, 0xFF0000, 100);
canvas_mc.moveTo(_xmouse, _ymouse);
};
mouseListener.onMouseMove = function() {
if (this.isDrawing) {
canvas_mc.lineTo(_xmouse, _ymouse);
}
updateAfterEvent();
};
mouseListener.onMouseUp = function() {
this.isDrawing = false;
};
Mouse.addListener(mouseListener);
The
MovieClip.getNextHighestDepth()
method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components
DepthManager class instead of the
MovieClip.getNextHighestDepth()
method.
