Remove g_convert (moved to glib) and now useless utf_to_latin1() Thu Sep 14 12:21:12 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktexttypes.[ch]: Remove g_convert (moved to glib) and now useless utf_to_latin1() latin1_to_utf() * gtk/gtktextview.[ch]: Change ::move_insert and ::delete_text action signals to ::move and ::delete; create the signals with the right enumeration type, not GTK_TYPE_ENUM so that bindings work. Add C-d, M-d, C-v bindings, change Home, End to move to beginning/end of line, Add C-Home C-End to move to beginning/end of buffer. Change ::cut_text to ::cut_clipboard, etc; combine ::scroll_text into ::move; use new GtkSelectionData functions to simplify DND text handling. * gtk/gtkenums.h gtk/gtktextview.h: Move movement, deletion enumerations here, rename enumeration values to be consistently plural. * gtk/gtktextbuffer.c: Use new clipboard interfaces for cut/copy/paste and primary selection. * gtk/gtktextbuffer.[ch]: Remove excess time and 'interactive' arguments from cut/copy/paste; rename cut to cut_clipboard, etc; remove gtk_text_buffer_get_clipboard_contents(). * gtk/gtktextlayout.[ch]: Add gtk_text_layout_move_iter_to_line_end() to move the iter to line ends. * gtk/gtkselection.[ch] (gtk_selection_data_set/get_text): Functions to set or get a UTF-8 string on the selection data. * gtk/gtkclipboard.[ch]: New, simplified selection handling interfaces. * gtk/gtkinvisible.c (gtk_invisible_new): Realize newly created widgets - one of these is useless if we don't. * gtk/gtkselection.[ch] (gtk_selection_clear_targets): Export a public function clear all targets registered for the widget. * gtk/gtkselection.c (gtk_selection_owner_set) docs/Changes-2.0.txt: Never call gtk_widget_realize() - that was just asking for bizarre side-effects. * gtk/gtkselection.c (gtk_selection_owner_set): Call gdk_selection_owner_set even if the widget is the same so that we reliably update the timestamp on the server. * gdk/x11/gdkevents-x11.c gdk/x11/gdkx.h: Add a gdk_x11_get_server_time() function. * gdk/x11/gdkevents-x11.c gdk/x11/gdkprivate-x11.h gdk/x11/gdkselection-x11.c gdk/x11/gdkwindow-x11.h: Add some tricky filtering on serial numbers for selection clear events to fix up long-standard race condition FIXME's in gtkselection.c. * gdk/gdkproperty.h gdk/x11/gdkselection-x11.h: Add routines to convert from utf8 to compound text or STRING and from a text property to UTF-8. * gtk/gtkmain.[ch] (gtk_get_current_event_time): Add a convenience function gdk_get_current_event_time(). * gtk/gtkselection.c (gtk_selection_data_copy/free): Copy and free selection_data->data properly
