Is it possible at all to get and set these widths?
Is there another way to calculate the width of the label?
Or should I get the length of the label's values and then set width
to x

Assuming your XUL is of this structure, try this:
<grid><columns id=cols1"><column/><column/></columns><rows><row ...
/></rows></grid>
<grid><columns id=cols2"><column/><column/></columns><rows><row ...
/></rows></grid>
/* Set widths of columns of 2nd grid to widths of columns of first
grid. Untested */
var cols1=document.getElementById("cols1"),
cols2=document.getElementById("cols2");
for (var i=0, sz=cols1.childNodes.length; i<sz; i++) {
var width =
document.defaultView.getComputedStyle(cols1.childNodes[i],
"width").width); /* might be a cleaner way */
dump("width of col " + i + " " + width);
cols2.childNodes[i].setAttribute("style", "width: " + width); /*
overwrites other styles if they exist! */
}
This works like a charm, now. Next problem is that resizing both
columns leaves my window too small, so that needs resizing too now. I
can probably find it's current size and add the differences to that
too in much the same way.
Looks like I was cheering too early.
I set the grids/rows/columns contents from the same script as I use to
calculate the width. The width I read is still 0 (sometimes)...
Maybe I should add an eventlistener to onDOMChange, like Jesper
suggested, to wait for the changes I made to bubble through? Or is there
a better way to deal with this timing problem?
