You can get even more tricky by creating a js object in the code
preceeding the window.openDialog() call, and then you dont have to worry
about the order of the arguments:
foo={
apple : "red",
banana: "yellow",
orange: "green"
}
then call
window.openDialog("chrome://my/package/content/foo.xul",foo)
Then in the dialog you can always just use:
window.arguments[0].apple;
or
window.arguments[0]['banana'];
I ran into this problem with aim code. It's a pain to do it the other way because you
always have to make sure you keep the order of the arguments right, and if you want to
add a new argument, you have to add it to all the callers of that openDialog, lest
someone else add a new argument and not know they need a placeholder for your new
argument :)
