Sun Oct 21 23:27:00 2001 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_translate_coordinates): Fix problem with g_return_if_fail return value. * gdk/x11/gdkproperty-x11.c docs/Changes-2.0.txt: Move over the virtual atom code from the gdk-multihead branch, removing the per-display part. Virtualizing atoms needs to be done now to prevent compat breakage in direct Xlib accessing code in the future. (#62208) * gdk/x11/gdkx.h: gdk/gdk/x11/gdkproperty-x11.c: Export gdk_x11_xatom_to_atom, gdk_x11_atom_to_xatom(). * gdk/gdktypes.h docs/Changes-2.0.txt: Make GdkAtom an opaque pointer type so the compiler catches attempts to mingle it with X atoms. * gdk/x11/{gdkdnd-x11.c,gdkevents-x11.c,gdkglobals-x11.c, gdkkeys-x11.c, gdkmain-x11.c, gdkprivate-x11.c, gdkproperty-x11.c, gdkselection-x11.c, gdkwindow-x11.c} gtk/{gtkclist.c,gtkctree.c,gtkdnd.c,gtkplug.c,gtksocket.c} tests/testdnd.c,tests/testselection.c: Fix up for above atom changes. * gdk/gdkselection.h (GDK_SELECTION_CLIPBOARD): Add, since we now have the ability to add custom predefines. * gtk/{gtkentry.c,gtklabel.c,gtkoldeditable.c,gtktextview.c}: Use GDK_SELECTION_CLIPBOARD instead of GDK_NONE in calls to gtk_clipboard_get(). * gdk/win32/gdkproperty-win32.c: Add CLIPBOARD, fix up for GdkAtom => pointer change. * gdk/linux-fb/gdkproperty-fb.c: Fix handling of predefined atoms, fix for GdkAtom => pointer change.
