The Python API to define Panels and Operators is based on subclassing,
this makes that system more generic, and based on RNA. Hopefully that
will make it easy to make various parts of Blender more extensible.
* The system simply uses RNA properties and functions and marks them
with REGISTER to make them part of the type registration process.
Additionally, the struct must provide a register/unregister callback
to create/free the PanelType or similar.
* From the python side there were some small changes, mainly that
registration now goes trough bpy.types.register instead of
bpy.ui.addPanel.
* Only Panels have been wrapped this way now. Check rna_ui.c to see
how this code works. There's still some rough edges and possibilities
to make it cleaner, though it works without any manual python code.
* Started some docs here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/RNATypeRegistration
* Also changed some RNA_property and RNA_struct functions to not
require a PointerRNA anymore, where they were not required (which
is actually the cause of most changed files).
* Don't call generic layout hints templates anymore, i.e.
TemplateRow becomes Row, etc.
* Added more general layout nesting, using uiLayoutSplit()
and uiLayoutBox() functions, for which the sublayouts
can then be accessed using uiLayoutSub(), to put items
in those sublayouts.
* Some steps to make the layout decisions, like which items
to put in which columns, independent of the width of the
window or the text in the buttons. We want the layout to
be stable under resizes and translations.
* Added an "expand" parameter to uiItemR, used now to expand
enums into a row instead of using a menu.
There is a problem importing 3ds files where I cant find a way to check if the transforms are applied to the vertex locations or not.
Since 2.44 I made the importer assume they were not since you can manually remove transformations, but not reverse.
Nevertheless most 3ds files have the matrix applied, better not give a bad import by default.
Did some research and other 3ds importers (lib3ds for eg), have the same problem and just assume the transformations applied.
3dsMax imports both correctly so there must be a way to tell but I could not link it to the 3ds version or other mesh options.
Added an option to workaround this problem in rare cases where its needed.
- KX_GameObject.cpp & KX_Scene.cpp, clear the dict before removing the reference in case there is a circular reference.
- added DWG support, adapted Stani Michiels idea for binding an extern DXF-DWG-converter
The external DXF-DWG converter "dconvertcon.exe" 355kb comes from openDesignAlliance www.opendwg.org, is free, but not opensource, not GPL-compatible (can not be bundled with commercial programs), so must be downloaded and installed in Blender script folder by user. It is a DOS console application, can be started in background mode, works on Windows, and in Wine on Linux and OSX. Version 1.0 (2002) supports conversion between DXF<->DWG for autocad release: 2.5, 2.6, 9, 10, 11, 12, 13, 14, 2000, 2002.
Version string is compatible with all previous releases, but report
subversion if not 0.
Keep distribution dir so you can run from there without needed of unpack,
and make messages and cmds be in sync.
The bug was todo with bpy.data and bpy.types becoming invalid, temporary fix is to re-assign them to the bpy module before running python operators or panels.
will look into a nicer way to get this working.
this means it caches the compiled pyc files after importing fro the first time.
My times for importing 501 buttons_objects.py files were.
- running each as a script 1.9sec
- importing for the first time 1.8sec
- importing a second time (using pyc files) 0.57sec
Also added "bpy" to sys.modules so it can be imported.
* Added very basic loading of .py files on startup to define panels.
It now executes all .py files in .blender/ui on startup. Right now
this contains the object buttons, the C code for it is commented out.
These files should get embedded in the blender executable as well
eventually, that's a bit more complicated so this works for now.
* For scons and cmake it seems to copy & find the files OK, for make
only "make release" works (same with scripts/ folder it seems).
* Added BLI_gethome_folder function in BLI_util.h. This is adapted
from bpy_gethome, and gives the path to a folder in .blender like
scripts or ui.
There's plenty of things to figure out here about paths, embedding,
caching, user configs ...
Notes:
* Sequence transform strip uses G.scene global, this is commented
out now, should be fixed.
* Etch-a-ton code was most difficult to merge. The files already in
2.5 got merged, but no new files were added. Calls to these files
are commented out with "XXX etch-a-ton". editarmature.c and
transform_snap.c were complex to merge. Martin, please check?
* Game engine compiles and links again here for scons/make/cmake
(player still fails to link).
* added filter buttons to header
* changed large icon for movie files to match small icon
* fixed small stack corruption in interface_draw.c (Matt, check if this is ok)
* moved nice display of file size to storage.c, where string is created.
- cleaned up warnings (mostly unneeded variables)
- new icons for filebrowser (large refresh and parent icons missing though)
- fixed error in large icon drawing due to texture coordinates calculated outside subpart of texture.
- removed library loading stuff from filelist
There was very little structure in this code, using many globals
and duplicated code. Now it should be better structured. Most
things should work, the main parts that are not back yet are the
python plugins and markers. Notes:
* Blenfont is used for drawing the text, nicely anti-aliased.
* A monospace truetype font was added, since that is needed for
the text editor. It's Bitstream Vera Sans Mono. This is the
default gnome terminal font, but it doesn't fit entirely well
with the other font I think, can be changed easily of course.
* Clipboard copy/cut/paste now always uses the system clipboard,
the code for the own cut buffer was removed.
* The interface buttons should support copy/cut/paste again now
as well.
* WM_clipboard_text_get/WM_clipboard_text_set were added to the
windowmanager code.
* Find panel is now a kind of second header, instead of a panel.
This needs especially a way to start editing the text field
immediately on open still.
* Operators are independent of the actual space when possible,
was a bit of puzzling but got it solved nice with notifiers,
and some lazy init for syntax highlight in the drawing code.
* RNA was created for the text editor space and used for buttons.
* Operators:
* New, Open, Reload, Save, Save As, Make Internal
* Run Script, Refresh Pyconstraints
* Copy, Cut, Paste
* Convert Whitespace, Uncomment, Comment, Indent, Unindent
* Line Break, Insert
* Next Marker, Previous Marker, Clear All Markers, Mark All
* Select Line, Select All
* Jump, Move, Move Select, Delete, Toggle Overwrite
* Scroll, Scroll Bar, Set Cursor, Line Number
* Find and Replace, Find, Replace, Find Set Selected,
Replace Set Selected
* To 3D Object
* Resolve Conflict
This patch solves some major problems of the svg script :
- reading of the inkscape svg format
- parsing of the scientific numbers
- redundant arc data in the same path for only one command "a"
- blending of curves after several files import and at the end a more correct management of the current point.
- Scripts Help Browser: error parsing doc info wrapped in triple single quotes, like done in the 3ds importer. Thanks Jean-Michel (jms) for informing me about it.
- visualizing data, rendering scenes automatically and character rendering on a server.
This example script shows how you can run blender in background mode, parse arguments from the command line to generate a simple scene and render/save it.
