[README] Improving 3rdparty themes

[Christopher Roy Bratusek <zanghar freenet de>]

Hi all,

several of the 3rdparty themes aren't perfect, two issues with them can be solved easily - by YOU:

[I'm using mavosBOX as example]

I. It produces the following warning:

(call-after-property-changed 'WM_NAME ...) should probably be
(call-after-property-changed '(WM_NAME _NET_WM_NAME) ...);
use '(WM_NAME) if you really want only WM_NAME

then open the themes theme.jl and replace

  (call-after-property-changed
   'WM_NAME (lambda ()
	      (rebuild-frames-with-style 'mavosBox))))

by

  (call-after-property-changed
   '(WM_NAME _NET_WM_NAME) (lambda ()
	      (rebuild-frames-with-style 'mavosBox))))

II. When a lot of windows are open it becomes totally slow

this is caused by some themes reframing *all* open windows, not just those which actually need to be reframed

open the themes theme.jl and replace

  (call-after-property-changed
   '(WM_NAME _NET_WM_NAME) (lambda ()
	      (rebuild-frames-with-style 'mavosBox))))

by

  (call-after-property-changed
   '(WM_NAME _NET_WM_NAME) (lambda (w prop state)
	      (reframe-window w))))

That's it!

Once you've fixed the theme you're using, be sure to upload the new version to the wiki!

I'll do so now for mavosBOX

Happy Hacking,
Chris
