ChangeLog

2005-02-21  Kim F. Storm  <storm@cua.dk>

	* xdisp.c (move_it_vertically_backward): Eliminate two xasserts.
	I think those asserts are bogus if buffer contains invisible text
	or images.

2005-02-21  David Kastrup <dak@gnu.org>

	* gtkutil.c (xg_create_frame_widgets): UNBLOCK_INPUT on error.

2005-02-20  Kim F. Storm  <storm@cua.dk>

	* xdisp.c (pos_visible_p): Be sure to move to the specified
	position.  Always get the full ascent / descent of the
	corresponding row, to return reliable rtop and rbot values.
	(back_to_previous_visible_line_start): Fix 2005-01-18 change.
	Must look one character back, as back_to_previous_line_start
	returns position after the newline.
	(move_it_vertically_backward): Fix heuristic for when to move further
	back in case line_height * 2/3 is larger than window height.
	(cursor_row_fully_visible_p): Rename make_cursor_line_fully_visible_p
	as it does not do anything anymore.  Add arg current_matrix_p to
	use current matrix rather than desired matrix when set.
	(try_cursor_movement): Don't scroll to make cursor row fully
	visible if cursor didn't move.  This avoids unexpected recentering
	in case of blinking cursor or accepting process output.
	Use current matrix to check cursor row visibility.
	(redisplay_window): Fix whether to recenter or move to top in case
	cursor line is taller than window height.
	(find_first_unchanged_at_end_row): Stop search if we reach a row
	which not enabled (instead of abort).

2005-02-18  Kim F. Storm  <storm@cua.dk>

	* xfaces.c (Finternal_set_lisp_face_attribute): Allow :color property
	to be nil in a :box attribute value list; customize prints that
	as lisp value when no box color is specified.

	* .gdbinit (pitx, pit): Pretty print display iterator.
	(prowx, prow): Pretty print glyph row.
	(pcursorx, pcursor): Pretty print a window cursor.
	(pwinx, pwin): Pretty print struct window.

	struct selection_input_event to avoid aliasing issues.
	(SET_SAVED_MENU_EVENT): Adapt reference to inev.

	(setup_for_ellipsis, handle_single_display_spec)
	(handle_composition_prop, next_overlay_string)
	(get_overlay_strings, reseat_1, reseat_to_string)
	(next_element_from_ellipsis, BUFFER_POS_REACHED_P)
	(in_display_vector_p, display_line, get_next_display_element):
	Change it->method from function pointer to enum.
	(get_next_element): New array to map it->method to function.
	(get_next_display_element): Use it.

	(Fw32_get_clipboard_data): Handle CF_UNICODETEXT and
	CF_LOCALE.  Fall back to CF_TEXT, if CF_UNICODETEXT is not
	available.  Force DOS line-ends for decoding.

	(Fx_selection_exists_p): Handle CF_UNICODETEXT.

	(syms_of_w32select): Init and register new variables.

	* w32.h: Add prototypes for globals_of_w32select and

2005-02-08  Stefan Monnier  <monnier@iro.umontreal.ca>

	* undo.c (Fprimitive_undo): Check veracity of delta,start,end.

2005-02-07  Jan Dj,Ad(Brv  <jan.h.d@swipnet.se>

	convert long array returned from XGetWindowProperty to an int array.
	(x_set_tool_bar_lines): Check that width and height is greater than
	zero before clearing area.

	* xselect.c (x_reply_selection_request): Pass long array to

	(lisp_data_to_selection_data): When the input is a vector and the
	format is 32, allocate a long array even if long is bigger than 32 bits.
	(x_fill_property_data): Use char, short and long as the man page
	for XChangeProperty specifies.  This way the data returned is OK for
	both 32 and 64 bit machines.

	events so the menu event comes after them.  This is to prevent sit-for
	from exiting on buffered events directly after a menu selection,
	lisp code for Help => About Emacs uses sit-for.

	* gtkutil.c (create_menus): Connect selection-done event instead of
	the deactivate event to deactivate_cb.  This will make the last
	leave event come before the call to deactivate_cb, so the leave
	event does not make sit-for exit after a menu selection.

	but check new READABLE_EVENTS_* in argument flags instead of previous
	two boolean arguments do_timers_now and filter_events.
	If we are doing mouse tracking and the mouse moved, return only if
	READABLE_EVENTS_IGNORE_SQUEEZABLES is not set in flags.
	(swallow_events): Call get_input_pending with flag
	READABLE_EVENTS_DO_TIMERS_NOW.
	(get_input_pending): Move code from old get_filtered_input_pending
