Feature request - dynamic icon pixmap

Feature request - dynamic icon pixmap

[Sun Yijiang]

GNU Emacs' bitmapicon is a little ugly and not configurable -- that's
the truth.  XEmacs' elisp function x-set-screen-icon-pixmap can change
program icon dynamically, this is very useful when you're working with
sevral frames with different major modes -- they can have their own
icons in the "taskbar".  I wonder if this feature is in the TODO list
of GNU Emacs, If not, I suggest to have it added.

You can set the frame parameter icon-type to a icon file.  For the GTK 
version the format of the file can be any format supported by GdkPixbuf, 
but for other ports of Emacs it must be a bitmap.

Yes, I can change the default icon when I create a new frame:
(make-frame '((name . "testf") (icon-type . "/path/test.png")))

But I cannot change a frame's icon by modifying its icon-type parameter:
(set-frame-parameter my-frame 'icon-type "/path/test2.png")
Nothing happens after this under GNOME or KDE

That's what I mean by "dynamic".

Doing:

(set-frame-parameter (selected-frame) 'icon-type "~/foo.png")

Works for me in the openbox window manager as well as in widgets from
the gnome libwnck[1] library.

Are you sure you've given the correct image file name?  This works for 
me with all window managers I've tried, including KDE 3.3 and Gnome 2.6 
and 2.8.
