Sun Jun 28 04:29:10 1998 Tim Janik <timj@gtk.org> * gtk/gtktypeutils.c (gtk_type_class_init): call the base class init fucntions from all parent types upon class initialization. * gtk/gtkcontainer.c: (gtk_container_get_type): announce gtk_container_base_class_init to the type system. (gtk_container_base_class_init): new function to feature base class initialization. (gtk_container_get_child_arg): (gtk_container_set_child_arg): call the GtkContainerClass get_child_arg and set_child_arg methods of the class indicated through the argument name. * gtk/gtkobject.c: (gtk_object_base_class_init): new function to feature base class initialization. (gtk_object_init_type): announce gtk_object_base_class_init to the type system. (gtk_object_class_init): setup the get_arg and set_arg pointers for GtkObjectClass. (gtk_object_setv): (gtk_object_getv): call the GtkObjectClass get_arg and set_arg methods, instead of bothering the type system with this. * gtk/gtkaccellabel.c: * gtk/gtkbutton.c: * gtk/gtkradiobutton.c: * gtk/gtktable.c: * gtk/gtktogglebutton.c: * gtk/gtktipsquery.c: * gtk/gtkbox.c: * gtk/gtkpacker.c: * gtk/gtkwidget.c: * gtk/gtkwindow.c: * gtk/gtkframe.c: * gtk/gtkmisc.c: * gtk/gtklabel.c: set the object_class->{g|s}et_arg pointers to the corresponding gtk_*_{g|s]et_arg functions and updated the gtk_*_get_type functions wrt GtkTypeInfo initialization. changed a lot of the set/get arg functions to take a GtkObject argument. gtk/gtkadjustment.c: gtk/gtkalignment.c: gtk/gtkarrow.c: gtk/gtkaspectframe.c: gtk/gtkbbox.c: gtk/gtkbin.c: gtk/gtkcheckbutton.c: gtk/gtkcheckmenuitem.c: gtk/gtkclist.c: gtk/gtkcolorsel.c: gtk/gtkcombo.c: gtk/gtkctree.c: gtk/gtkcurve.c: gtk/gtkdata.c: gtk/gtkdialog.c: gtk/gtkdrawingarea.c: gtk/gtkeditable.c: gtk/gtkentry.c: gtk/gtkeventbox.c: gtk/gtkfilesel.c: gtk/gtkfixed.c: gtk/gtkfontsel.c: gtk/gtkgamma.c: gtk/gtkhandlebox.c: gtk/gtkhbbox.c: gtk/gtkhbox.c: gtk/gtkhpaned.c: gtk/gtkhruler.c: gtk/gtkhscale.c: gtk/gtkhscrollbar.c: gtk/gtkhseparator.c: gtk/gtkimage.c: gtk/gtkinputdialog.c: gtk/gtkitem.c: gtk/gtkitemfactory.c: gtk/gtklist.c: gtk/gtklistitem.c: gtk/gtkmenu.c: gtk/gtkmenubar.c: gtk/gtkmenuitem.c: gtk/gtkmenushell.c: gtk/gtknotebook.c: gtk/gtkoptionmenu.c: gtk/gtkpaned.c: gtk/gtkpixmap.c: gtk/gtkpreview.c: gtk/gtkprogressbar.c: gtk/gtkradiomenuitem.c: gtk/gtkrange.c: gtk/gtkruler.c: gtk/gtkscale.c: gtk/gtkscrollbar.c: gtk/gtkscrolledwindow.c: gtk/gtkseparator.c: gtk/gtkspinbutton.c: gtk/gtkstatusbar.c: gtk/gtktext.c: gtk/gtktoolbar.c: gtk/gtktooltips.c: gtk/gtktree.c: gtk/gtktreeitem.c: gtk/gtkvbbox.c: gtk/gtkvbox.c: gtk/gtkviewport.c: gtk/gtkvpaned.c: gtk/gtkvruler.c: gtk/gtkvscale.c: gtk/gtkvscrollbar.c: gtk/gtkvseparator.c: updated the GtkTypeInfo initialization code to match the modified GtkTypeInfo structure.
