Bug 547270 – Make GtkHSV public
|
||||
|
||||
* gtk/Makefile.am
|
||||
* gtk/gtk.h: install gtkhsv.h as public header (its symbols were
|
||||
always public anyway).
|
||||
|
||||
* gtk/gtkhsv.h: add single-include guards, add class struct padding,
|
||||
seal the instance member, cleanup.
|
||||
|
||||
* gtk/gtkhsv.c: center the widget in its allocation,
|
||||
add "Since: 2.14", cleanup.
|
||||
|
||||
2008-08-11 Torsten Schoenfeld <kaffeetisch@gmx.de>
|
||||
|
||||
* gtk/gtkcalendar.h: Fix the Since: tag of GtkCalendarDetailFunc
