This commit is aimed at cleaning up the filtering code by changing the
filtering idiom/pattern used. While the old code used a "check then
do" approach, the new code does a "grab then assimilate".
The main benefits are that:
* the code duplication that used to exist has now been removed, making
it easier to add new channel types for data
* a recursive "peeking" ability now means that the old problems with
data existing deep in the tree (i.e. figuring out whether a channel
should be shown based on whether it will have any descendents) should
now work much better than before.
In the process, I've found and fixed a few previously unnoticed bugs
with how some channels were constructed, so hopefully things work a
bit better now.
TODO's:
* Action-Group filtering stuff hasn't been refactored yet. This was
causing some grief in the past, so I still need to check this
carefully.
* Material Nodes support (missing in trunk) should be easy to slot in
now :)
Python:
* adds bpy.app.handlers which contains lists, each for an event type:
render_pre, render_post, load_pre, load_post, save_pre, save_post
* each list item needs to be a callable object which takes 1 argument (the ID).
* callbacks are cleared on file load.
Example:
def MyFunc(scene): print("Callback:", data)
bpy.app.handlers.render_post.append(MyFunc)
C:
* This patch adds a generic C callback api which is currently only used by python.
* Unlike python callbacks these are not cleared on file load.
Usage currently is limited to:
- Panel text, widget text and label text style:
point size, shadow effects
Setting individual fonts to these is not possible yet, it uses the
default for it.
Access goes via outliner now; check "User Preferences". UI team could
add this in userpref scripts :)
This was causing a lot of backward compatibility problems and side effects.
It has to be done properly, linked with Material ObjectColor shader_flag or at least the TF OBCOLOR (which apparently worked at some point so I've been told).
If you need to use OBCOLOR simply keyframe the obcolor and it will work as before.
* BL_DeformableGameObject is no longer responsible for handling keys, BL_ShapeDeformer is
* BL_ShapeDeformer also creates a copy of the key on construction and puts it back on the mesh when destructed. This avoids us permanently modifying Blender data.
* I'm not too fond of clearing out the key every frame, but this works and I can't think of another alternative at the moment (something may be possible with some key juggling)
In addition the billboards can be scaled by the particle velocity with optional head and tail factors (similar to line drawing options). This allows for pseudo-motionblur effects.
The rna set function clamps to the property range however properties with range functions were ignored when set by python or the animation system.
Now call the range function for ints and floats when setting.
* Insert Key on Selected Channels in Action Editor was broken
* Transform/Select All tools in Action Editor were broken as result of
filtering changes.
* Set Visibility operator, when used from Graph Editor now does
similar things to the TabKey lock/unlock operator with regards to the
flags it uses for filtering
the list of animated curves is closed
At long last, this old bludger can be put out to pasture. I figured it
would involve some of the visibility-filtering stuff I added, but this
required a bit extra effort than anticipated.
* This (big) commit is aimed at cleaning up the filtering flags used
by the animation channel filtering code. The list of filtering flags
has been growing a bit "organically" since it's humble origins for use
in the Action Editor some 3 years (IIRC) ago now during a weekend
hackathon. Obviously, some things have ended up tacked on, while
others have been the product of other flag options. Nevertheless, it
was time for a bit of a spring clean!
* Most notably, one area where the system outgrown its original design
for the Action Editor was in terms of the "visibility" filtering flag
it was using. While in the Action Editor the concept of what channels
to include was strictly dictated by whether the channel hierarchy
showed it, in the Graph Editor this is not always the case. In other
words, there was a difference between the data the channels
represented being visible and the channels for that data being visible
in the hierarchy.
Long story short: this lead to bug report [#27076] (and many like it),
where if you selected an F-Curve, then collapsed the Group it was in,
then even after selecting another F-Curve in another Group, the
original F-Curve's properties would still be shown in the Properties
Region. The good news is that this commit fixes this issue right away!
* More good news will follow, as I start checking on the flag usage of
other tools, but I'm committing this first so that we have a stable
reference (of code similar to the old buggy stuff) on which we can
fall back to later to find bugs (should they pop up).
Anyways, back to the trenches!
