[Anygui-checkins] CVS: anygui/lib/anygui/backends javagui.py,1.49,1.50

[Magnus L. H. <ml...@us...>]

Update of /cvsroot/anygui/anygui/lib/anygui/backends
In directory usw-pr-cvs1:/tmp/cvs-serv9458/lib/anygui/backends

Modified Files:
	javagui.py 
Log Message:
Checked in a semi-functional ListBoxWrapper. I don't think the
wrapper itself is that flawed -- but int uncovered some strange
behaviour in javagui itself. For some reason, in enterMainLoop,
the ListBoxWrapper's parent is a dummy, something which is not
true for LabelWrapper.
