This means we can do operator drawing without passing self.properties as an argument.
while this check if quite specific, if this gives problems later on we should probably change operators not to try to mix an operator and its properties, it looks nice to a scripter but internally is not easy to manage.
* Fix var declaration in bpy_interface.c
* Remove forward declarations from py_capi_utils.h: they are unnecessary and break compiles (there were probably many warnings about this during compile with GCC).
- BKE_add_image_extension now sets the extension rather then appending. (no more image.jpg.tga)
- py/rna functions which have no return value now raise an error if a non-None value is returned.
- added back the red-alert flag so buttons can have a red highlight if somethings wrong.
The reason this didnt work is all sibclasses of pythons type() or PyType_Type in C, have to have their size set to sizeof(PyHeapTypeObject) rather then sizeof(PyTypeObject) as you might expect.
This is strange since its not a heap-class (defined in pythons runtime), but a static C type, so Im not sure about this, and cant find any documentation but it seems to work ok.
- operator properties are now converted into python property() class members which bypass the operator 'properties' member.
self.properties.mysetting
... can now be written as ...
self.mysetting
- fix for error reloading rigify
eg:
bpy.types.Scene.myprop = BoolProperty()
note, this uses an ugly python metaclass, this should be replaced with a C implimentation which is included but commented out, causing crashes in pythons GC which gives no hint as to where the bug comes from.
- rna internal deferred properties now store the functions as PyObjects rather then C function pointers
- Property functions now allow the first non keyword argument to be a class.
Setting the classes __dict__ member directly didnt update the types slots (python internal type stuff used with subclassing), so class.bl_rna was returning an incorrect value.
Set the value using typical python setattr command.
cant test if this fix solves the problem matt is having but it at least fixes an error caused by classes created in exec(),
when the properties pointers were copied the hash key still referred to the python object which could be freed. in most cases this wouldnt happen (would be kept in bytecode) but with exec() the property string is freed immediately.
- ID properties now suopport non utf-8 strings for their values but not their keys.
- moved utility functions into py_capi_utils.c from bpy_utils and bpy_rna.
- import/export paths have to be printed with repr() or %r, so non utf-8 chars are escaped.
- OBJ import/export now work with non utf8 paths. (all exporters and importers need changes like this)
- strip non utf8 chars from new ID blocks (also applies to renaming)
- set the file rename button to allow non-utf8 chars.
- user input gets non utf8 chars stripped all text input other then file paths.
- python has the same limitations, it will raise an error on non utf8 strings except for paths use unicode escape literals so its possible to deal with saving to these file paths from python.
- new string functions
BLI_utf8_invalid_byte(str, len) returns the first invalid utf8 byte or -1 on on success.
BLI_utf8_invalid_strip(str, len) strips non utf-8 chars.
- mesh.add_geometry(v, e, f) --> mesh.vertices.add(tot), mesh.edges.add(tot), mesh.faces.add(tot)
- mesh.add_material(mat) --> mesh.materials.link(mat)
changed material.link so it always adds a material even if it exists in the list, this behavior is good for users but not scripts since it can mess up indicies (some formats may have the same material set twice).
eg:
row.prop_search_self(scene, "active", "keying_sets", text="")
...becomes
row.prop_search(scene.keying_sets, "active", scene, "keying_sets", text="")
This is more flexible since it works for other UI functions too.
eg:
bpy.context.StringProperty(attr='myprop'); del bpy.context.myprop
- made rna StringProperty/PointerProperty & similar into class methods.
- file selector hide option was inverted
- they now share the same code so it wont happen again.
- added id_data to properties so we can do...
matrix = C.object.matrix_world
obj = matrix.owner.id_data # get the original object back.
An example of how this is useful - an importer mixin could define the filepath properties and a generic invoke function which can run the subclasses exec for each selected file.
- Panels and Menus now skip the property check when registering.
- renamed _idproperties_ to _idprops_ in function names, function names were getting very long.
