When you add the widget to the swin, the hadjustment and vadjustment will be set, so that the scrollbars control the widget. The widget may want to handle scrolling specially, like the tree view does (make sure headers always visible). However, you may want to insert some widget that doesn't know how to scroll itself (such as a box full of buttons). In this case, you use a GtkViewport. The viewport is just one GdkWindow packed inside another. The inner window is expanded to the requested size of the viewport's child (which may be larger than the containing GdkWindow. To scroll, it just repositions the inner GdkWindow, which scrolls the child. So if you have a viewport between the scrolledwindow and the tree view, the tree view won't be able to scroll itself (the viewport will perform the scrolling).

Check the glade file to see if there is a GtkViewport between the TreeView and ScrolledWindow. If so, that could be the cause of the problem. If there is, then the GtkViewport will be handling the scrolling, and the TreeView won't handle things correctly (as far as it is concerned, it will have been given enough space to display all the rows).

Is the treeview packed inside a gtk.ScrolledWindow? If not, try doing that. The tree view should handle scrolling correctly in that case. swin = gtk.ScrolledWindow() swin.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC) swin.add(treeview) James. -- Email: [EMAIL PROTECTED] | Linux.conf.au 2003 Call for Papers out WWW: http://www.daa.com.au/~james/ | http://conf.linux.org.au/cfp.html ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
