This is actually just an intermediate refactoring that uses
gimp_image_get_foo_list() inetad of get_foo_iter(), but it also
sanitizes saving the image's selection (it's now simply added to the
list of channels to save, instead of using some sick code to save it
in the same loop that saves channels), so i want to have this in a
separate commit from actual tree saving/loading.
The opposite of gimp_item_get_path(), just that it doesn't return an
item, it returns a parent item and an index that can be used to add
the item to an item tree.
As when loading channel props (which can replace the GimpChannel by a
GimpSelection), pass a GimpLayer** instead of a GimpLayer* to
xcf_load_layer_props(), so the function can replace the GimpLayer to
load by another type (e.g. GimpGroupLayer).
Add XCF property PROP_LOCK_CONTENT and save/load it for all layers and
channels. Vectors saving needs some refactoring here I'm afraid, so I
ignored it for now.
Use the new API whenever we want to determine the item's effective
lock state (whether we can write to the item's content or not). Use
gimp_item_get_lock_content() only in code that actually deals with
*this* item's locked state, which is only the PDB wrappers and GUI to
modify the flag on the item itself.
Begin to consider GimpObject::name as private and always use
gimp_object_get_name(). Change gimp_object_get_name() to take an
untyped pointer so we don't have to do so awfully many casts. There is
a runtime check for the type inside the function anyway.
"lock-content" will be separate from "is-group" soon, so add separate
checks for groups. Also remove some checks that were added to make
wrappers invokable even though the group appeared locked.
New function returns FALSE and sets an appropriate error if invoked on
a group item. Use it from gimp_pdb_get_vectors_stroke() because if we
ever get vectors groups, they will have no strokes.
The idea that group layers count as locked was a bad one, start adding
separate checks for group layers, and refuse to modify them with
distinct error messages.
- gimp_container_tree_view_prepend_toggle_cell_renderer() to
gimp_container_tree_view_add_toggle_cell()
- gimp_container_tree_view_prepend_cell_renderer() to
gimp_container_tree_view_add_renderer_cell()
because "prepend" is an implementation detail, "renderer" is obsolete,
and in the second case it's not "cell renderer" but really a "renderer
cell".
Even though a user can only save to XCF in File->Save, the "All
images" filter shall show all images to allow a user to steal names
from non-XCF images and vice versa for File->Export, so make that
happen.
Make sure a group layer really emits all needed size change signals
when children get added and removed, so the group layer above it can
also update itself based on these signals. Spotted (again) by tobi.
