Example
The following example uses the Drawing API to draw a rectangle when the user presses the
mouse button, moves the mouse, and then releases the mouse button at runtime.
this.createEmptyMovieClip("canvas_mc", this.getNextHighestDepth());
var mouseListener:Object = new Object();
mouseListener.onMouseDown = function() {
this.isDrawing = true;
this.orig_x = _xmouse;
this.orig_y = _ymouse;
this.target_mc = canvas_mc.createEmptyMovieClip("",
canvas_mc.getNextHighestDepth());
};
mouseListener.onMouseMove = function() {
if (this.isDrawing) {
this.target_mc.clear();
this.target_mc.lineStyle(1, 0xFF0000, 100);
this.target_mc.moveTo(this.orig_x, this.orig_y);
this.target_mc.lineTo(_xmouse, this.orig_y);
this.target_mc.lineTo(_xmouse, _ymouse);
this.target_mc.lineTo(this.orig_x, _ymouse);
this.target_mc.lineTo(this.orig_x, this.orig_y);
}
updateAfterEvent();
};
mouseListener.onMouseUp = function() {
this.isDrawing = false;
};
Mouse.addListener(mouseListener);
