2000-11-07 Havoc Pennington <hp@redhat.com> * gtk/gtktextmark.c (gtk_text_mark_is_visible): rename to gtk_text_mark_get_visible * gtk/gtktextlayout.c (gtk_text_layout_move_iter_to_line_end): fix bug that was generating an invalid iterator * gtk/gtktextiter.c (gtk_text_iter_get_offset): move call to ensure_char_offsets() in front of code placing the iter in an invalid state. * gtk/gtktextbuffer.c (gtk_text_buffer_paste_primary): make override_location arg const (paste): Replace the selection if we paste into the current selection * gtk/gtkselection.h: Remove "GtkSelectioData" (struct _GtkSelectionData): move the definition here. * gtk/gtktextbuffer.c (gtk_text_buffer_update_primary_selection): Export the GTK_TEXT_BUFFER_CONTENTS target for in-process copies * gtk/gtktextiter.c (gtk_text_iter_get_tags): New function * gtk/gtktextbuffer.c (gtk_text_buffer_insert_range): implement (gtk_text_buffer_insert_range_interactive): implement (gtk_text_buffer_get_tags): Remove, replaced by gtk_text_iter_get_tags() * gtk/gtktextiter.c (gtk_text_iter_forward_search): Add a search limit parameter, to avoid infinite linear scan. (gtk_text_iter_backward_search): Add search limit (gtk_text_iter_forward_find_char): Add search limit (gtk_text_iter_backward_find_char): Add search limit
