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)
