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).
More cleanup!
- removed old UI font completely, including from uiBeginBlock
- emboss hints for uiBlock only have three types now;
Regular, Pulldown, or "Nothing" (only icon/text)
- removed old font path from Userdef
- removed all old button theme hinting
- removed old "auto block" to merge buttons in groups
(was only in use for radiosity buttons)
And went over all warnings. One hooray for make giving clean output :)
Well, we need uniform definitions for warnings, so people at least fix
them... here's the real bad bugs I found:
- in mesh code, a call to editmesh mixed *em and *me
- in armature, ED_util.h was not included, so no warnings for wrong call
to ED_undo_push()
- The extern Py api .h was not included in the bpy_interface.c, showing
a several calls using different args.
Further just added the missing includes, and removed unused vars.
* Fix sometimes non-working close/open button.
* Fix panels being a bit out of the view on startup.
* Fix too large totrct region for view2d.
* Fix wrong panel order when changing vertical <-> horizontal.
* Fix wrong panel positions after switching contexts.
* Fix an access of freed memory when collapsing panels.
* Free align mode works again.
* Animations work again.
- Register python panels
- Added a generic class checking function BPY_class_validate() for panels/operators.
- No button drawing yet
Brecht, Added RNA_enum_value_from_id() and RNA_enum_id_from_value() to rna_access.c to do lookups between identifiers and values of EnumPropertyItem's, Not sure if these should go here.
this can be brought back as a new space if someone decides to
work on it.
This also fixes remaining issues with the outliner tree open
and close buttons not working sometimes.
* operator class names
- Changed 'name' to '__label__' (since __name__ is already used for the class name)
- Changed 'properties' to '__props__'
* added a PyObject_GetAttrStringArgs(), utility function which Id like to see in pythons C api.
PyObject_GetAttrStringArgs(pyob, "someattr", "foo", "bar") /* pyob.someattr.foo.bar */
* As a test, used by:
* Object buttons, tried to make it match the mockup.
* Text window header.
* Text window properties panel.
* Panel interaction with view2d is still problematic, need to make
this work properly still.
* Templates are very basic, the ones there are simple but already
can follow the object buttons mockup quite closely.
* It's based on a three level system: panels, templates and items.
To get an idea of what that means in practice, see:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/UI_LayoutEngine#Panels.2C_Templates_and_Items
example...
bpyui.registerKey( C, bpyui.spaceTypes.SEQ, 0, "Sequencer", "SEQUENCER_OT_view_selected", bpyui.keyTypes.A, bpyui.keyValTypes.PRESS, 0,0, {})
May want to split this into multiple functions.
Can draw panels in the scripts space containing RNA and operator buttons.
* Added bpyui.register() so scripts can draw buttons and panels into the scripts space type.
* wrapped drawBlock, drawPanels and matchPanelsView2d
* Operator buttons take a python dictionary used to set the button defaults.
* BPY_getFileAndNum utility function to get the filename and line number python is currently running.
And a popup block with python callback with bpyui.pupBlock, beginBlock, popupBoundsBlock and endBlock funcions.
These functions should not be accessed by scripters directly.
