Browse Source 
2003-05-23  Matthias Clasen  <maclas@gmx.de>

	* gtk/gtknotebook.c: Add support for up to four scroll
	arrows. Control their display by new style properties
	"has_forward_stepper", "has_backward_stepper",
	"has_secondary_forward_stepper" and
	has_secondary_backward_stepper". (#110540)

	* gtk/gtknotebook.h (struct _GtkNotebook): Make in_child and
	click_child three bits wide, add
	has_{before,after}_{previous,next} fields.
