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
