Adapt to GtkTreeSelection changes
2001-01-01 Havoc Pennington <hp@redhat.com>
* gtk/gtktreeview.c: Adapt to GtkTreeSelection changes
* gtk/gtktreeselection.c (_gtk_tree_selection_set_tree_view):
don't fill in tree_view->priv->selection, kind of an unexpected
side effect
* gtk/gtkcellrenderertext.c: Remove definition of _ and include
gtkintl.h
* gtk/gtkcellrenderer.c: Remove definition of _ and include
gtkintl.h
(gtk_cell_renderer_get_property): remove calls to g_value_init
* gtk/gtkcellrendererpixbuf.c: Remove definition of _ and include
gtkintl.h
* gtk/gtkcellrenderertextpixbuf.c: Remove definition of _ macro
and include gtkintl.h
(gtk_cell_renderer_text_pixbuf_class_init): remove spaces from
property names
* gtk/gtktreeselection.c (_gtk_tree_selection_new): rename, return
GtkTreeSelection
(_gtk_tree_selection_new_from_with_view): rename, return
GtkTreeSelection
(_gtk_tree_selection_set_tree_view): rename with uscore
(gtk_tree_selection_get_selected): fill in the "model" out param
first, so it gets filled in even if we return at the top of the
function
(gtk_tree_selection_real_select_all): add a comment and an else{}
to clarify this a bit
(gtk_tree_selection_real_unselect_all): add the same else{}
* gtk/gtktreeselection.h: Rename new, new_with_tree_view, and
set_tree_view to have underscore prefixes, move them to the
private header, fix return type of new_with_tree_view
(struct _GtkTreeSelection): mark struct
fields private
* gtk/gtktreemodel.c (gtk_tree_model_get_flags): return
GtkTreeModelFlags, not a guint
(gtk_tree_path_prev): return gboolean not gint
(gtk_tree_path_up): return gboolean not gint
* gtk/gtktreemodel.h (struct _GtkTreeModelIface): make get_flags
return GtkTreeModelFlags, not a guint
* gtk/gtktreemodelsort.c (gtk_tree_model_sort_finalize): check
that child model is non-null before unrefing it
(g_value_int_compare_func): make this a qsort compare func, not
a boolean predicate
* gtk/gtktreemodelsort.h: rename gtk_tree_model_set_sort_column,
(add -umn to the end), and mark it unimplemented
(gtk_tree_model_sort_resort): remove, this wasn't implemented, and
I don't see what it's for - doesn't the model always sort itself?
(gtk_tree_model_sort_set_compare): this had the wrong signature
* gtk/gtktreeviewcolumn.c (gtk_tree_view_column_set_attributes):
Fix the docs to say that it destructively replaces existing
attributes (previously said that it added attributes).
(gtk_tree_view_column_set_visible): canonicalize bool before
equality testing. Also, check for realization before
hiding/showing the tree_column->window; if this window could exist
before realization, then it's busted and needs fixing, we can't
create GDK resources pre-realization. Also, remove
superfluous queue_resize(), since set_size() does that for us.
(gtk_tree_view_column_set_col_type): check realization before
using tree_column->window
* gtk/gtktreedatalist.c: fix filename in copyright notice

adapt to handle PangoColor
2001-01-26 Havoc Pennington <hp@redhat.com>
* gtk/gtktextlayout.c (convert_color): adapt to handle PangoColor
* gtk/gtktreeview.c (gtk_tree_view_widget_to_tree_coords): fix to
not offset by TREE_VIEW_HEADER_HEIGHT
(gtk_tree_view_tree_to_widget_coords): fix to not offset by
TREE_VIEW_HEADER_HEIGHT
* configure.in (included_loaders): for me, --with-included-loaders
generates the error "the specified loader yes does not exist",
i.e. the arg defaults to "yes", so change test for value ""
to test for value "yes", and include all loaders in that case.
* gtk/gtkrbtree.c (_gtk_rbtree_get_depth): new function
* gtk/gtktreeview.c (gtk_tree_view_get_cell_rect): fix to properly
handle TREE_VIEW_VERTICAL_SEPARATOR
(gtk_tree_view_bin_expose): fix to consider the row offset as
pointing halfway into vertical separator.
(gtk_tree_view_draw_node_focus_rect): ditto
* gtk/gtkdebug.h, gtk/gtkmain.c (gtk_init_check): Add
--gtk-debug=updates, which causes gdk_window_set_debug_updates
(TRUE) to be called.
* gdk/gdkwindow.c (gdk_window_set_debug_updates): Allow enabling a
debug mode where the invalid region is colored in on invalidate,
so you can see the flicker and know whether your redraw code is
doing a good job.
* gtk/gtktreeview.c (gtk_tree_view_queue_draw_node): Work in
tree window coordinates (clip rect is in tree window coords)
* gtk/Makefile.am: add gtktreednd.[hc]
* gtk/gtkliststore.c: implement gtktreednd interfaces.
* gtk/gtktreednd.c, gtk/gtktreednd.h: New interface to support
drag-and-drop data operations on a model (so we can set up tree
drag-and-drop automatically)
* gtk/testgtk.c: Add a window to change sensitivity in the
GtkLabel test; add a way to change the entry frame in GtkEntry
test
* gtk/gtkentry.c (gtk_entry_set_has_frame):
(gtk_entry_get_has_frame): new functions to remove the frame
around an entry
(gtk_entry_size_request): shrink requisition if no frame
(gtk_entry_draw_focus): don't draw frame if no frame
* gtk/gtkstyle.c (gtk_default_draw_check): draw custom look for
checks inside a cell renderer
(gtk_default_draw_option): ditto for options
* gtk/gtktreeviewcolumn.c (update_button_contents): add/remove
children from the alignment, not the button
(gtk_tree_view_column_init): ref/sink the column, to emulate
GObject refcounting.
* gtk/gtkcellrenderer.c (gtk_cell_renderer_init): ref/sink
* gtk/gtkcellrenderertoggle.c (gtk_cell_renderer_toggle_render):
Use theme functions to draw the toggles
* gdk/gdkpango.c (gdk_pango_get_gc): use GdkRGB to alloc colors
* gdk/gdkpango.h, gdk/gdkpango.c: Add GdkPangoAttrStipple and
GdkPangoAttrEmbossed to use in rendering insensitive text
* gdk/gdkpango.c (gdk_draw_layout_line): render new properties
* gtk/gtkstyle.c (gtk_default_draw_layout): handle sensitivity
using new GDK features
