Frame Tree Dump
<bz> for a frame dump, you can use the layout debugger, or... if you're in a debugger and want to examine the tree, you can do
def frametree
set $r = ($arg0)->PresContext()->GetPresShell()->GetRootFrame()
if ($r)
call ((class nsIFrameDebug*)(class ViewportFrame*)$r)->List(stderr, 2)
end
end
<bz> That should work when called on any nsIFrame to dump the tree it belongs to
Printing nsIAtoms
def satom p *((class nsStaticAtomWrapper*)$arg0)->mStaticAtom end
<bz> to be used as: satom content->Tag() or satom frame->GetType()
<bz> for nsGkAtoms it'll work great
Reflow Logs
