Get position of a bpatcher on load

Title says it all; how can I get the position of a bpatcher within its parent patcher upon loading?
Banging a ‘window getsize’ message to a thispatcher within the bpatcher doesn’t appear to work, and anyway, this would get the patchers location relative to the screen origin, not the parent patcher’s,
cheers

You can do this with javascript, it looks like you’d need something like the following in a [js] object in the subpatch you have loaded into the [bpatcher]:

function loadbang() {
    loc = this.patcher.box.rect;
    outlet(0,loc[0],loc[1]);
}

If you want to avoid javascript, you can use pattr and the @bindto attribute:

– Pasted Max Patch, click to expand. –
