However I see that I can’t avoid the second part of the patch I first cut out. Gtk (also the Gtkmm samples for DND) crashes when an ancestor is moved into a descendant. To check this one has to access the row\_drag\_data of a Gtk::SelectionData. This part of the API is not exposed. I updated the patch to pass the Gtk::TreeStore and the Gtk::TreePath received from the selection instead. (If this is not desired, and if the original API should be exposed, I attached a second patch adding the necessary calls to Gtk::SelectionData.) Kind regards, Philipp K. ---

Is it possible that you did not re-run extconf.rb? Kind regards, Philipp K. BTW: 20060816\_ruby-gnome2\_0.14.1\_fetch\_data\_from\_selection.diff does also contains the other patch, by accident. * * * Using Tomcat but need to do more? Need to support web services, security?

I checked it. I’ll add the feature. But as you say, the coding style is defferent from ours. And it may be better both of signals are implemented to Gtk::TreeDragDest, Gtk::TreeDragSource, not Gtk::ListStore, Gtk::TreeStore.

That should not be that hard to fix, it is not much code. The patch to the already existing files hopefully adhered to it, though. > And it may be better both of signals are implemented to > Gtk::TreeDragDest, Gtk::TreeDragSource, not Gtk::ListStore, Gtk::TreeStore. Well, yes, I wasn’t able to figure how to do that. The TreeDrag(Dest| Source) code looked at bit like dummy code. I think you need to derive anyway, to override vfuncs of an interface, and as there is no possibility to code a generic store directly from within Ruby this looked like the best way to me, but then I am not expirienced with this extension. It should be _documented_ for TreeDrag(Dest|Source), though. Kind regards, Philipp K. * * * Using Tomcat but need to do more? Need to support web services, security?
