2000-09-29 Havoc Pennington <hp@redhat.com> * gtk/gtktexttag.c (gtk_text_tag_set_priority): fix indentation * gtk/gtktextview.c: Implement drag thresholding; change functions that set border window size to have nicer name (gtk_text_view_mark_set_handler): Fix this to have the right signature. * gtk/testtextbuffer.c (fill_buffer): Update with pixbuf changes * gtk/testtext.c: Update with API changes, put line numbers on both sides. * gtk/gtktextiter.c (gtk_text_iter_get_pixbuf): Replace get_pixmap with this * gtk/gtktextchild.h, gtk/gtktextchild.c: replace all pixmap with pixbuf; delete a big block of #if 0 Tk code * gtk/gtktextbuffer.c (gtk_text_buffer_insert_pixbuf): Replace insert_pixmap with insert_pixbuf
