This prevents chat windows from supplanting the roster (if they have the same Classname).
You learn something every day :) This is great - a significant improvement over matching on Classname. Thanks!
I wonder whether matching on Role or Title is preferable, or whether it makes no difference?
With Pidgin doubt there's much difference. Title has always worked fine for me for this specific purpose. However, Title is a bit flakier in general, since apps sometimes set title dynamically, or wait till after they're mapped to set it. So overall I vote role better than title. Didn't think of matching Role here simply because forgot that it's already predefined for IM layout. If it were used in a manageHook instead, it would have required an extra bit of explanation / definition. role = stringProperty "WM_WINDOW_ROLE" -- wmw
