That looks promising, I'll give it a go. I'll let you know how it turns out.
Thanks a lot David

It sounds like you need something like javascript's getElementById().
Then you could store the id of the open window in an attribute, then
convert the id string into an object. I've looked through the docs and
can't find anything like that for ids. Which is odd, and means I am
almost certainly missing it.
If all of your buttons are in or about the same view you can
accomplish this quite easily using names.
(not tested)
<view>
<attribute name='openbutton' type='string' />
<button name='button1'>
<handler name='onclick'>
if (parent.openbutton) {
var oldButton = parent[parent.openbutton];
oldButton.close();
}
parent.openbutton = this.name <http://this.name>;
</handler>
</button>
</view>

Sorry, I think my question was poorly put. Here's what I'm trying
to do.
I've created a class of buttons that when pressed animate to the
centre of the screen and display a description of the item (see
attached screenshot). What I'm having trouble with is determining
which button is open and closing it when another button is pushed.
Here's own I'm calling the class (for testing purposes)
<abutton id="PWNButton" x="1200" y="100"
theText="desc:/desc/PWN/text()" Logo="PWN"
Site="http://www.yahoo.com"; <http://www.yahoo.com>
ImageCalc="1.0350877193"/>
And here's the handler I was trying when a button is clicked
<handler name="onclick">
Debug.write('Current open button = '+OpenButton);
if (OpenButton == null) {
OpenButton = classroot.id
<http://classroot.id>;
Debug.write('New open button = '+OpenButton);
classroot.OpenDisplay.doStart();
return;
} else {
OpenButton.CloseDisplay.doStart();
classroot.OpenDisplay.doStart();
OpenButton = classroot.id
<http://classroot.id>
Debug.write('New open button = '+OpenButton);
}
</handler>
The problem is that when I do this I get "TypeError: Cannot call
method 'doStart' of undefined" - referring to
OpenButton.CloseDisplay.doStart.
I suppose I could use a switch statement to decide which button is
open by creating an open attribute but this also seems a little
messy.
Thanks for your reply,

You use the id as a drop-in replacement for your variable.
<canvas>
<view id='firstview' visible='false' />
<script>
Debug.debug(firstview.visible)
</script>
</canvas>
prints false to the debug console.

Many times I've referenced an active view by opening them like so
OpenBW = new lz.BigWindow(canvas, {x:xcor, y:10, width:wid});
OpenBW = something like this <BigWindow>#3 /BigWindow
after doing this I can refer to that view using the variable
OpenBW.
In a project I'm currently working on it would be pretty
messy to spawn all of my views like the one above but I still
would like to be able to reference them.
How can I do this?
I've tried to assign the Id of the view I want to control to
a variable and I've also tried getUID but both of these
return "TypeError: Cannot call method 'doStart' of undefined"
Can someone please help
