Owen Taylor a1a252ce46 Get rid of a bunch of g_strdup_printf("%s%s") in favor of g_strconcat(). 
Fri Feb  2 12:26:50 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrc.c (gtk_rc_add_initial_default_files): Get rid of
	a bunch of g_strdup_printf("%s%s") in favor of g_strconcat().

	* gtk/gtkrc.c Makefile.am: Use $(libdir), not $(exe_prefix),
	since some people set $(libdir) separately. (#1290, David Kaelbling)

Thu Feb  1 18:25:46 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkfilesel.c: If PATH_MAX and MAXPATHLEN are not
	defined, define MAXPATHLEN to 2048. (The Hurd doesn't have
	MAXPATHLEN, but the code here depends on a fixed value.)
	(#4524)

Wed Jan 31 22:01:04 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkhandlebox.c (gtk_handle_box_button_changed): Handle the case
	where child == NULL and handle_position == RIGHT or BOTTOM. (#8041g)

Wed Jan 31 21:20:39 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkctree.c (real_tree_move): If the node being moved isn't
	viewable there is no way that moving the node will cause the
	focus row to become not viewable, so omit check on the visibility
	of new_sibling, which is irrelevant. (Fixes #8002, David Helder)

Wed Jan 31 20:38:17 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkentry.c (gtk_entry_commit_cb): Delete the current
	selection before inserting new text.

Wed Jan 31 18:49:33 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkoptionmenu.c (gtk_option_menu_item_state_changed_cb):
	Make the sensitivity of the reparented child track that of
	the original parent menu item. (#34218, David Hodson)

	* gtk/gtkoptionmenu.c (gtk_option_menu_item_destroy_cb): Handle
	the case where the current item is destroyed properly.

	* gtk/gtkoptionmenu.c: Some additional code cleanups and fix
	some edge cases with child-less menuitems.

Wed Jan 31 17:16:13 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkcombo.c (gtk_combo_window_key_press): Make Return
	key pop down window. (#12074, Jon K Hellan)

Wed Jan 31 16:21:42 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtklist.c (gtk_list_signal_item_toggle): Don't allow
	toggling of rows off in BROWSE or EXTENDED mode. (#12072, Jon K Hellan)
	The solution here isn't perfect - you get an extraneous
	emission of "toggle", which could conceivably confuse an app,
	but better than the current situation. LXR search seems to
	indicate that no apps in GNOME CVS connect to "toggle".

Wed Jan 31 15:46:13 2001  Owen Taylor  <otaylor@redhat.com>

        * gtk/Makefile.am (libgtkinclude_HEADERS): Move gtkcompat.h from
        gtk_public_h_sources to directly here to avoid warning when
        building srcdir != builddir. (#9656)

Tue Jan 30 19:49:02 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrange.c: Patch from Kipp Hickman to make the event
	handlers in gtkrange.c return the proper values (TRUE == handled)
	(#10316).

	This is just the tip of the iceberg, but gtkrange.c is the
	most common place where the propagation is problematical,
	and also a place where it is almost certainly safe to change
	this in the stable branch.

	(You don't want right click popups on a range control or anything...)

Tue Jan 30 18:57:59 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktext.c (clear_focus_area): We need to clear the focus
	area on focus out, even if a background pixmap isn't set.
	(#13941)

Tue Jan 30 18:24:10 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtknotebook.c (gtk_notebook_set_shape): Fix from Sean Cunningham
	to deal with setting the shape properly when scrolling arrows are
	turned on, but not visible because there is sufficient space.
	(#13432)

Tue Jan 30 16:39:25 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkitemfactory.c (gtk_item_factory_delete_item): For menu
	items with submenus, destroy the item along with the submenu.
	(#7841, Brian Masney(?)) Also, handle paths of the form '<foo>/abcd...'
	properly.

	* gtk/testgtk.c (menu_items): Add a dummy branch that we delete
	later.

Tue Jan 30 15:51:25 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkwindow.c (gtk_window_real_set_focus): Fix a problem where
	the focus widget sometimes wasn't drawn with the default if there
	was no default widget.

	* gtk/gtkstyle.c (gtk_style_real_unrealize): free colors,
	unreference pixmaps.

	* gtk/gtkstyle.c (gtk_style_realize): Reference colormap
	for some extra safety.

Mon Jan 29 19:00:01 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtk{ctree.c,clist.c} (set_cell_contents): Handle setting
	the text of a cell to the old pointer value better, by
	copying the new text before freeing the old text. Some code
	cleanup. (#8079, Karl Nelson)

Mon Jan 29 16:50:19 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtklabel.[ch] gtk/gtkframe.[ch]: Make gtk_label_get_text()
	gtk_frame_get_label() non strdup'ing, and G_CONST_RETURN.

Mon Jan 29 15:22:51 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkmenu.c (gtk_menu_remove): When removing an
	item from a menu, check to see if it matches
	menu->old_active_menu_item, and if so, unref and clear
	old_active_menu_item (Patch from Pavel Cisler)

	* gtk/gtkmenushell.c (gtk_menu_shell_remove): Unset
	menu_shell->active_menu_item, if it is the child being
	removed. (Patch based on that of Gene Ragan, #50337)
