top most window id?

[rvj]

is there a xul function that will allow a script to determine the id or
handle of the active window task ?

in otherwords the task on the task bar which is the top most window

(this may or may not be a Mozilla application)

I think no. You wouldn't be able to do anything with such a handle
anyway (from JS).

thanks

the problem I have is that I want to find a general method of changing the
colour of the top most window
(I have a custom titlebar using the xul titlebar element)

My hope was to be able to compare the current task id with those listed
using the Mozilla windows mediator

if false , then a non Mozilla application has focus and all of the Mozilla
tasks are in background.
if true then I simply apply the colour to the relevamt Mozilla task

*******

NB I did try usingg CSS window:focus which works except that I have nested
xul windows
which means that different one window within the same physical window
potentially can have focus.

consequently I dont really have a method which guarentees the physical
window has changed focus

PS

Ideally windows mediator should list all application tasks (task bar)
identifying which are Mozilla (xulrunner) tasks and which of the tasks has
focus
