the GtkClutterViewport actor was removed because it was not as useful or as flexible as it looked like. you can easily implement the same functionality in a custom Actor sub-class overriding the apply_transform() virtual function, and calling cogl_matrix_translate() on the passed transformation matrix; the offsets can come from a MxAdjustment, a GtkAdjustment or two properties bound to any model. ciao, Emmanuele. -- Emmanuele Bassi, Intel Open Source Technology Center _______________________________________________ clutter-app-devel-list mailing list [email protected] http://lists.clutter-project.org/listinfo/clutter-app-devel-list
