 yes... it didn't work.  a layout within a layout - i think it was a
QHorizontalLayout within a QGridLayout - didn't want to be removed.
it's probably a bug.

 well, it just made vast amounts of sense - cut out all the middle
men.  if you're going to pull in a 17mb binary dependency, why do it
in a clumsy way?

 in order to pull in flash plugins and other material, the accepted
method in pygtk2 is to use python-gtk-mozplugger.  that's crazy.
embed an _entire_ web browser, just to pull in a flash component.
likewise, for doing a single bit of HTML, in pyqt4 and/or pygtk2, pull
in a 17mb binary dependency using python-webkit-qt4 and/or
pywebkitgtk, _just_ to display _one_ bit of HTML text??  _that's_

especially as webkit actually has far better rendering capability,
features and flexibility than any of the standard desktop widget sets
which had been designed for the job!

wonderfully ironic...

oh - for completeness, if anyone's reading this and goes "no chance i
will _ever_ convert to the pyjamas API because i've spent so much time
writing pygtk2 apps" - there is a project by luis pamirez, where he
has _reimplemented_, and to sit _on top_ of
the pyjamas DOM model.

at present, it's only available in the subversion repository of, and you'll need to check out a revision some
time around sep 2007 of the llpamies branch.

basically, what that will give you is a means to run your pygtk2
applications... in a web browser!

very cool.  i'll do a port to pyjamas-desktop at some time, if i have
a need for it, and will be happy to help guide anyone who wants to
spend the time on it themselves.

well, it's not _my_ toolkit - i just use it.  but you're right
inasmuch as i won't be initiating any new applications using pyqt4 or
pygtk2, not out of personal choice, anyway.
