2008-11-11 Michael Natterer <mitch@imendio.com> Bug 553765 – Add orientation API to GtkRange * gtk/gtkrange.[ch]: implement the GtkOrientable interface. Add evil code that makes sure that the stepper_detail and slider_detail set in GtkRangeClass continue to work with the hacked subclasses below. * gtk/gtkscale.[ch]: swallow all code from GtkHScale and GtkVScale and add gtk_scale_new() and gtk_scale_new_with_range() which take a GtkOrientation argument. Set slider_detail to "Xscale" so above evil code works. * gtk/gtkscrollbar.[ch]: add gtk_scrollbar_new() which takes a GtkOrientation argument. Set stepper_detail to "Xscrollbar" so above evil code works. * gtk/gtkhscale.c * gtk/gtkvscale.c * gtk/gtkhscrollbar.c * gtk/gtkvscrollbar.c: remove all code except the constructor and call gtk_orientable_set_orientation() in init(). * gtk/gtk.symbols: changed accordingly. svn path=/trunk/; revision=21779
