Dynamically adding a mouse click event to button movieclip

[ranco]

Hi,
I'm trying to load a set of button movieclips (already located in the Library) dynamically. Their position and other variables are defined externally in an XML file.

I've tried to "generate" an onRelease() event handler using "this[mc].onRelease = function()" but it doesn't seem to work properly and I'm really not sure this is the right way to go.

Here is a code snipset, after the xml is loaded into an array Items:

  
var nIcons:Number = Items.length;
var xStep:Number  = Stage.width / (2*nIcons);
var xPos:Number   = xStep;
var yPos:Number   = Stage.height - 70;
for (var i:Number = 0; i < nIcons; i++)
{
	var name:String = Items[i].Name;
	var mc:String = name + "_mc";
	this.attachMovie(mc, mc_mc, this.getNextHighestDepth());
	this[mc]._x = xPos;
	this[mc]._y = yPos;
	this[mc].myid = mc;
	this[mc].onRelease = function()
	{
		trace(" click " + myid);
	}
	xPos += 2*xStep;
}

The thing is that the trace always generates the same result - which is myid of the last loaded icon.

Please advise,

Thanks in advance,

You are trying to use onRelease on a movieclip.
It's only for buttons ...

You could try onMouseDown and onMouseUp too maybe ?

There are many different kind of events in Flash Lite ... I always had to check a bunch of them before finding the proper one.

I'm talking about button symbols; they are sometimes refered to as movieclips; anyway, not Button controls. and onRelease() is available for these.

One of the easiest way to pass through this problem is hitTest API & a logic. Just write a function which test that which button the user hits via mouse and return its value to onRelease function .Write something like this:

// chk bt returns the index of item which is pressed
function chk_bt() {
	for (var i:Number =0; i< nIcons ; i++) {
// u can replace the nIcon variable with the one having the number of total dynamic buttons created
	        var name:String = Items[i].Name;
	        var mc:String = name + "_mc";	
                temp = eval(mc); // or _root[mc] if they are in root or this[mc] 
		if (temp.hitTest(_xmouse, _ymouse)) {
			break;
		}
	}
	return i;
}

Now , write onRelease function like this :

this[mc].onRelease = function()
	{
		trace(" click " + chk_bt());
	}

Wish u luck ..

Unfortunately buttons doesn't have hiTest, so this idea didn't work...
Maybe I should put the button inside a movieclip?
any other idea?

Thanks,

Not a big deal.You can write one of ur own hitBt function in less then a minute like this:

function hitBt(mc:MovieClip)
{
var bol:Boolean = false;
if (_xmouse >= mc._x && _xmouse <= (mc._x +mc._width) && _ymouse >= mc._y && _ymouse <= (mc._y + mc._height))
{
bol = true;
}
return bol;
}

Thats it . Wish u luck.
