2005-08-29 Matthias Clasen <mclasen@redhat.com> Add a cross-platform "tray icon" API, by porting EggStatusIcon/EggTrayIcon (#105101) * gtk/gtkstatusicon.h: A GtkStatusIcon is an object which displays an icon in a notification area. * gtk/gtkstatusicon-x11.c: GtkStatusIcon implementation for X11, using GtkTrayIcon. * gtk/gtktrayicon.h: * gtk/gtktrayicon.c: An implementation of the freedesktop.org system tray specification, not public API. * gtk/gtk.symbols: Add new exported functions. * gtk/gtk.h: Include gtkstatusicon.h. * gtk/Makefile.am: Add new files. * tests/Makefile.am: * tests/teststatusicon.c: Test for GtkStatusIcon.
