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;
</handler>
</button>
</view>
