Support insensitive cells in tree views and combo boxes:
* gtk/gtkcellrenderer.h:
* gtk/gtkcellrenderer.c: Add a ::sensitive property.
* gtk/gtkcellrendererpixbuf.c (gtk_cell_renderer_pixbuf_render):
* gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_render):
* gtk/gtkcellrenderertoggle.c (gtk_cell_renderer_toggle_render):
Support drawing insensitive.
* gtk/gtkcellview.h:
* gtk/gtkcellview.c (gtk_cell_view_get_cell_renderers): New
function to obtain the cell renderers from a cell view. Also
export gtk_cell_view_set_cell_data().
* gtk/gtktreeselection.c (tree_column_is_sensitive):
* gtk/gtktreeselection.c (row_is_selectable): Helper functions
to determine whether all visible cells in a row are insensitive
and whether a row is selectable. A row is not selectable if the
user function says so or if all visible cells are insensitive.
* gtk/gtktreeselection.c (_gtk_tree_selection_internal_select_node):
* gtk/gtktreeselection.c (gtk_tree_selection_real_select_node):
Use row_is_selectable().
* gtk/gtkcombobox.c (row_is_sensitive):
* gtk/gtkcombobox.c (tree_column_row_is_sensitive):
* gtk/gtkcombobox.c (menu_row_is_sensitive): Helper functions
to determine row sensitivity in menu or list mode.
* gtk/gtkcombobox.c (update_menu_sensitivity): Helper function
to set up sensitivity menu items from the underlying rows.
* gtk/gtkcombobox.c (gtk_combo_box_popup):
* gtk/gtkcombobox.c (gtk_combo_box_menu_button_press): Use
update_menu_sensitivity().
* gtk/gtkcombobox.c (gtk_combo_box_list_setup): Setup the cell
data funcs.
* gtk/gtkcombobox.c (gtk_combo_box_key_press): Skip insensitive
rows.
* tests/testcombo.c (main): Make some rows insensitive.
