it's not a hard dependecy on the instace, the sni geometry handling is just plain broken. the workaround operates on configure events on the mapped window which will go nowhere if there's no running wm. the client needs to handle the no-wm case, ie. configure the window correctly, but to repeat myself: such requirement implies that either sni or qwidget/qwindow is completely fucked up. qwindow/qwidget::setGeometry should justwork(tm) - Thomas ----------------------------------------------------------- This is an automatically generated e-mail.
