Since python-xlib relies on low level X11 objects/methods, it would be necessary to develop a completely new python GUI manager from XLib. I know there is such a project, known as PLWM (http://plwm.sf.net), but never tested it. BTW, the python-xlib/PLWM dev teams both released new version of their softwares yesterday. > Oh and on the subject of xlib, the menus in the sample apps dont seem to be > working for me, is this a known issue or just me? > As I said a few days ago, I didn't move all the samples yet to the new graphic driver system. If you want to get them work, you have to replace the line: from wxSampleGui import display, start_display with: from SimpleGui import display, start_display. > > Regards, > Best Regards, > > Henrik Rudstrom > Thomas > > > _______________________________________________ > Pythonocc-users mailing list > Pythonocc-users@gna.org > https://mail.gna.org/listinfo/pythonocc-users > >
