* The python 'math' library is now included in the py-namespace used to evaluate button expressions. So it is now possible to do 'radians(somevalue)' to get a rotation value that Blender can understand...
* Shapekey path getting function now uses the appropriate wrapper for grabbing the pointer to the ID block for the ShapeKey
* Made the Graph Editor's minimum zoom size finer...
I've finally given in, and implemented a '2d-cursor' for the Graph Editor. This is simply represented as an additional horizontal line that meets with the current frame indicator, forming a cross-hair. It can be disabled from the View menu.
Currently, the only tool which takes this into account is the Snapping tools (Shift-S), where I've hooked up a tool I added some time ago.
TODO:
- expose this cursor to the transform tools for scaling/rotation options...
Toggling one of the visibility toggles in the Graph Editor now flushes the new value up/down the hierarchy.
- when enabling a visibility toggle, all the 'higher' up and lower down channels get their visibility turned on
- when disabling a visibility toggle, only the ones lower down get their visibility turned off (since there might still be other channels at the same level which are still enabled.
This makes showing/hiding groups of F-Curves much easier, since previously you'd have to use multiple clicks to isolate particular F-Curves. For example, to isolate only X Location curves, previously, the workflow would have been to select all AKEY, hide all VKEY, then toggle the individual X Location curves in group, then make sure the groups and objects, etc. were also visible. Now, the steps of making sure that the parents were visible too has been eliminated.

Also, fixed a few minor bugs with the animation-backend code for Graph Editor.
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
to .py files as well to make creating distributable configurations
easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.
* Updating Preview Range settings results in correct updates for Animation Editors
* Compositing nodes now correctly animate when the values were set by IKEY/RMB on suitable node parameters. Beware that these nodes are not relinkable node-trees, hence the standard code not working.
* Ctrl-P to parent objects to bones now works in Pose Mode too. I needed to add a special keymap entry for this, though I thought this would have been better to be automatically inherited/present from Object keymap already?
* Ctrl-P -> Parent to Bone option now works correctly again. 1.5 lines of code missing here...
* Breakdowns tool now shows custom cursor during 'modal' phase so that it's not that confusing what's going on.
their handlers based on notifiers, which is simpler and more
reliable.
This fixes for example editmode or uv edit keymaps not working
when creating a new 3dview or image space.
Notifiers
---------
Various fixes for wrong use of notifiers, and some new notifiers
to make things a bit more clear and consistent, with two notable
changes:
* Geometry changes are now done with NC_GEOM, rather than
NC_OBJECT|ND_GEOM_, so an object does need to be available.
* Space data now use NC_SPACE|ND_SPACE_*, instead of data
notifiers or even NC_WINDOW in some cases. Note that NC_SPACE
should only be used for notifying about changes in space data,
we don't want to go back to allqueue(REDRAW..).
Depsgraph
---------
The dependency graph now has a different flush call:
DAG_object_flush_update(scene, ob, flag)
is replaced by:
DAG_id_flush_update(id, flag)
It still works basically the same, one difference is that it now
also accepts object data (e.g. Mesh), again to avoid requiring an
Object to be available. Other ID types will simply do nothing at
the moment.
Docs
----
I made some guidelines for how/when to do which kinds of updates
and notifiers. I can't specify totally exact how to make these
decisions, but these are basically the guidelines I use. So, new
and updated docs are here:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/NotifiersUpdateshttp://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataNotifiers
Now the mute/protect/expand/etc. toggles are drawn using UI widgets. This means that special event handling code to determine when they were clicked on is no longer needed, and also means that there can now be tooltips for these items too.
Also, added visibility toggles for ID-block expanders, which will cause all the F-Curves in the linked datablock to not get drawn. The backend filtering code to make this work will come later...
* Animated ShapeKey F-Curves/Drivers are now visible in the Animation Editors.
* As a result of this, the old 'ShapeKeys' mode (which would display all the shapekey channels, even if they had no keyframes yet) in the DopeSheet, no longer works for now. However, it would have been of no use as no sliders were shown anyway.
* Drivers which depended on the rotation of bones now work again. These now point to the right RNA properties, and get some extra 'time' corrections (for degrees -> radians change).
* When resizing the window, the top position is now preserved,
instead of the center position.
* Fix zoom level not being preserved in various cases, when
changing both with and height. This replaces some earlier code
which did this at screen level but wasn't very reliable.
* Different tabs now each preserve their own scroll.
* When switching between tabs, it now scrolls to show as many
buttons as possible, instead of possibly showing empty space.
There is a trade-off here between doing that keeping the
buttons in the same place, no ideal solution exists I think.
* Change zooming in/out to be symmetric, for example doing
numpad + then - did not give the original zoom level back.
* Added some calls to avoid hanging tooltips when manipulating
the view.
Internals:
* Added V2D_KEEPOFS_X and V2D_KEEPOFS_Y to keep the top/bottom
rather than the center.
* Renamed V2D_KEEPZOOM to V2D_LIMITZOOM (seems more appropriate),
and make V2D_KEEPZOOM preserve the zoom level.
* Split strips now uses the current frame as the splitting-point for selected strips if the current frame falls within in the bounds of the strip. Otherwise, the code defaults to splitting by the midpoints of the strips.
* Time-range for Graph Editor is saner now when there is only a single keyframe or none at all.
I've gone through all the Animation Editor operators, making sure they send appropriate notifiers, and that these notifiers are handled.
* Added a separate category for animation-related notifiers, since the old-style ones attached to specific datatypes only was turning out to be not too feasible.
* For now, the focus has been on making sure that all Animation Editors update when there have been any potentially suitable changes at all. Later on, we can filter these more carefully to only take the ones we really need (for optimisation purposes)
* When influence/time for NLA-strips are animated, settings in the other panels which used to control these are now greyed out to show that they won't have any impact over the result.
* NKey panel for Graph Editor now opens on Right-Hand Side, just like for NLA Editor. The small sub-region above the Channels region was too troublesome to work with.
Cleanup of scroller drawing in 2D windows.
Before:
http://download.blender.org/institute/rt11.jpg
After:
http://download.blender.org/institute/rt12.jpg
Will add 'zoom' widget circles later, as mockupped here:
http://www.reynish.com/files/blender25/fcurve_scrollbar.png
Also note the scale values are inside scroller; drawing it
on top conflicts with current frame item and markers.
Currently scroller disappear entirely when view is total.
For Joshua:
To make sliders behave nicely, the boundbox (v2d->tot) has to
be refreshed on each change. I've added it in graph drawing
now, but it could be notifier based I guess... not sure what
the correct anim api call would be. Can discuss tomorrow!
On todo:
Layout config hints so people can make scroller positions swap.
* Fix buttons jumping around when resizing and zoom. Part of this was
adding a tiny a 0.001f offset in UI_view2d_view_ortho, otherwise the
rounding is unpredictable (used to be 0.375f, but that was disabled).
* Fix various issues with zooming, panning panels. V2D_LOCKOFS_X/Y is
now taken into account in more places in the view2d code, to avoid
zooming into the center or panning out of the view.
* Remove "Free" align mode in buttons window (it's not really useful).
* View3D/Graph/Image editors now use the same PanelType system as the
buttons window, means some deprecated panel code could be removed.
* Some small visual tweaks for panels.
* View 2D Reset operator (Home key), to reset zoom and panning for panels.
* Added argument to set number buttons as sliders (slider=True for itemR).
* Ignore labels for button alignment (doesn't look right).
* Fix some use of context.main in py scripts, should get data from active
object instead.
* Fix autotexspace -> auto_texspace in py script.
Summary of ain features:
- Themes and Styles are now editable.
- CTRL+U "Save user defaults" now goes to new .B25.blend, so you
can use 2.4x and 2.5x next to each other. If B25 doesn't exist, it
reads the regular .B.blend
- Press Tkey in 3d window for (unfinished) toolbar WIP. It now only
shows the last operator, if appropriate.
Nkey properties moved to the other side.
A lot of work was done on removing old themes for good and properly
getting it work with the 2.5 region system. Here's some notes;
- Buttons now all have a complete set of colors, based on button classifications
(See outliner -> user prefs -> Interface
- Theme colors have been extended with basic colors for region types.
Currently colors are defined for Window, Header, List/Channels and
for Button/Tool views.
The screen manager handles this btw, so a TH_BACK will always pick the
right backdrop color.
- Menu backdrops are in in Button theme colors. Floating Panels will be in
the per-space type Themes.
- Styles were added in RNA too, but only for the font settings now.
Only Panel font, widget font and widget-label work now. The 'group label'
will be for templates mostly.
Style settings will be expanded with spacing defaults, label conventions,
etc.
- Label text colors are stored in per-space Theme too, to make sure they fit.
Same goes for Panel title color.
Note that 'shadow' for fonts can conflict with text colors; shadow color is
currently stored in Style... shadow code needs a bit of work still.
This feature takes a 'snapshot' of the visible+selected F-Curves, and displays these in the background as 'ghosts curves' in the background. Such curves are drawn semi-transparent, slightly darker, and with dotted lines.
To use, simply click the 'curve' button beside the Auto-Snapping selector. To clear, simply click that button again (with a different icon now).
These 'ghost curves' are stored per Graph Editor instance, and are not saved to file (i.e. per session only). They are useful to be used as guides when refining the shape of existing curves.
* Currently, this only works for the 'Expanded polynomial' mode, but this will be expanded to include the other modes too. Now you can modify the values and interactively see the graph in the view change.
* Disabled the backdrops (modifier 'panels') temporarily, as ROUNDBOX UI elements currently swallow all events, which is not good.
Note: the code here still uses the old-style UI definition code since the new stuff is still under heavy construction.
* Rewrote the Generator modifier to be more efficient and support more options
* A few UI tweaks for this, but the UI for this is still not yet functional though.
- Completed cleaning up the drawing code so that F-Curves with modifiers now get drawn to reflect this.
- Added a temporary operator to add modifiers (hotkey Ctrl-Shift-M)
Useful goodies: most buttons for Image window back.
Not every button works! But what you can do:
- press Nkey to show/hide options
- use curves, with realtime updating
- image properties panel, load, browsing layers,
setting types
- paint panel
- plus new paint color picker panel! (why it wasn't
there in 2.4x is probably obvious, but now it can!)
Hrm... radial control should be added here too, and a nice
paint size cursor?
Graph Editor: added region for buttons (properties), so we can
check drivers again! Works like view3d, press NKEY. No buttons
there yet though... no time anymore today, it'll require some
RNA magic probably.
Made sliders behave correct in SpaceGraph and SpaceAction.
- no slider draw when all is visible
- sliders update correct when visibility changes.
Still an issue here to tackle; view2d->tot is used incorrect...
it's set on window size now (??), it should be the boundbox of
the entire contents. That allows correct slider draws and ops
like 'view home'.
Will poke Joshua tomorrow. :)
Graph editor: added refresh tagging on initialize; this is called
on browsing space types, as well on read files or switch screens.
(Makes the fancy fluorescent rainbow colors in channels appear!)
Now F-Curve channels in channels region are drawn with the same colour as their respective curve is drawn in the curves area. I've had to make a compromise to store such colour info in F-Curves themselves, which is not terribly ideal if the F-Curve gets reused in some way. However, for now, this will do (special tweaks can be made to make this work better though).
I've also added a colour-determination mode per curve which should in future allow more control over this. By default, all curves still use the old 'rainbow' style. The available types area:
* Old Rainbow - Colour is determined 'automatically' using a magic method which uses curve position + total curves to generate a colour.
* Auto RGB - Color is determined using the 'array index' stored in F-Curve for data-access. An unresolved issue with this is that all the curves with this will end up with exactly the same colour, leading to confusion (i.e. all location.x and scale.x properties could potentially all be the same red colour).
* Custom colour - self explanatory
Currently, there's a minor bug when loading old files where the colours don't get initialised yet. For now, just clicking in the Graph Editor after file-load will solve any of these problems.
Ton: it looks like area->refresh() isn't getting called after file read.
* Scene and World AnimDatas are now included in animation editors
* Keyframes for integer-value settings now get the FCURVE_INT_VALUES flag set for their F-Curves, which restricts those curves to only having integer-values. F-Curve displays have been altered accordingly, but some editing tools may still need tweaks to work with this.
* Fixed notifiers for Insert Keyframe -> Active Keying Set.
When inserting keyframes on previous un-animated Objects/bones, F-Curves will be added into Action Groups into either "Object Transform" or <PoseChannel Name>. Ob->Material settings are not grouped for now to illustrate what's possible.
Old files are currently not patched to use do this, as it's still not clear whether this will be ideal.
* Removed Sequencer's own 'border zoom' tool. There is a generic one in View2D that should be used instead.
* Changed the hotkey for View2D's version of borderzoom to Shift-B
* Fixed a few hotkey mentions entries in old menus
* Added set start/end frame operators for TimeLine. (SKEY and EKEY)
* Fixed various issues in Graph Editor
- channels area is now drawn wide enough to show the 'protect' toggles without needing to scroll
- new Graph Editors have 'auto-snap' enabled by default
As creator of the Ipo I also reserve to right to kick it out
definitely :) To honour the wonderful contributions from Joshua
here it is; renamed space_ipo to space_graph!
Note; make, cmake and scons should work, msvc will require some
work now!
