Part of T95802.
Showing properties with an RNA path in the UI isn't very user friendly.
Instead, represent the RNA path as a tree, merging together parts of the
RNA path that are shared by multiple properties. Properties and "groups"
(RNA structs/pointers) are now shown with their UI name and an icon if
any. The actually overridden properties still show the Library Overrides
icon. See the patch for screenshots.
Also: When a RNA collection item, like a modifier or constraint was
added via a library override, indicate that item and show all collection
items in the list, since the complete list of items and their orders may
be important context.

No user visible changes expected.
We have a bunch of "base" element types, just to show a label element
for grouping together other elements. There is no reason to have these
tied to a case, just have a generic label type for this. It requires a
string to display, and can display an icon too. The new element type
isn't used yet, but will be in one of the following commits. Would be
nice if the existing base elements can be replaced by this.

Use a shorter/simpler license convention, stops the header taking so
much space.
Follow the SPDX license specification: https://spdx.org/licenses

While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they

Also use doxy style function reference `#` prefix chars when
referencing identifiers.

Code to check if the Outliner tree-element type was the general ID one
would always check against "0" (explicity or even implicitly). For
somebody unfamiliar with the code this is very confusing. Instead the
value should be given a name, e.g. through an enum.
Adds `TSE_SOME_ID` as the "default" ID tree-element type. Other types
may still represent IDs, as I explained in a comment at the definition.
There may also still be cases where the type is checked against "0". I
noted in the comment that such cases should be cleaned up if found.

These weren't used since ages. Comment out the DNA define (value shouldn't be
reused to avoid compatibility breakage) and remove icon code for the types.
|
|
We generally prefer using enums over precompiler defines. This adds an actual
type for the values, which the compiler can use to throw warnings, give better
messages, etc.
|
|
This wasn't used for a long time and there are no plans to bring this back.

Having a centeral place to find a list of all library overrides should be
useful for managing production scenes where library overrides are used a lot.
This change adds the individually overridden properties of a data-block under
the data-block itself. Just how we show modifiers, constraints or pose channels
there. This way we can also expose library override operations/options better
in future.
There's also a filter option for the library overrides now, so they can be
hidden. It is only available in the View Layer display mode though, like the
other filter options.
One internal change this has to do is adding more informative return values to
undo pushes and the library override functions called by it. That way we can
send a notifier when library overrides change for the Outliner to know when to
rebuild the tree.

The icons for collapsed children already draw highlighted when hovered.
Because the item icons are now select targets (for outliner to properties
editor tab switching) this adds highlights on hover for all outliner
element icons.
|

Some DNA headers already did this, most did not. Even though many of them would
be included in C++ files and thus compiled as C++. This would be confusing and
developers may think they have to add `extern "C"` too a whole lot of
(indirect) includes to be able to use a C header in C++.
However, this is a misconception.
`extern "C"` does not cause code to be compiled with C rather than C++! It only
causes the linker to not use C++ function name mangling. See
https://stackoverflow.com/a/1041880.
Because extern DNA headers don't have function declarations, using `extern "C"`
actually should not have any effect. On the other hand, adding it causes no
harm and avoids confusion. So let's just have it consistently in C header
files.

This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.

Walk navigation used a separate flag to select the element. This is
because activation and mode toggling were connected until rB702e00f91088
cleaned up the selection logic.
Now walk navigation can activate objects and other elements without
changing modes. This also addresses renaming in the outliner which
did renaming from the active element, not the walk element.
|
|
Adds a keyboard walk navigation and selection operator to the
outliner. Up and down arrow keys walk up and down the list of
elements, and left and right will open and close elements if
the elements are closed or opened respectively. Holding shift
while walking up and down the tree expands the selection.
Holding shift while clicking or pressing left and right arrows
will expand or collapse all children elements recursively.
Pressing enter to openclose the hovered element is removed.
Also allows click+drag for openclose of element subtrees.
This moves openclose toggling to the openclose operator to
remove duplicate code. The outliner tree building is tweaked
slightly to set the proper parents in scene display mode for walk
select to walk to parents without errors.
|
|
Adds a toggle to the filter menu for outliner synced selection. Enabled
by default, this ensures selection is synced between objects, bones, and
sequences. An active outliner element theme color is added to indicate
which element is active.
Synced selection is controlled on the operator level. Each operator
that modifies selection for objects, bones, sequences, or outliner
elements needs to call the respective ED_outliner_select_sync_from..
function to tag outliners to be synced.
Syncing is done lazily on outliner draw.

* Drag and drop between multiple outliners now works.
* Dragging the icon and text now give the same results.
* Fixes various crashes.
|

OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

* "Scenes" now shows for each scene lists of all view layers, collections and
objects contained in it. This is the place to see all collections and objects
in the scene even if they are not used in any view layer. Objects are nested
according to parenting here.
* "Collections" now shows all collections in the view layer, and the objects
in those collections. Objects are not nested by parenting, only collections
since it would be too confusing if the children are in a different collection.
* "Groups" is unchanged.
* "View Layer" was removed, replaced by "Collections".

We have different ways of explore the scene objects, namely View Layer and
Collections. This change let us focus on compositing elements only such as:
* View Layers
** Collections
** Render Passes
* Freestyle
* Grease Pencil?
Not included in this commit is an option to handle filtering of
collections passes, ... Not sure if we would like, though.
Since they are all properly nested under a "Collections" / "Passes"
parent.

This is not the original reported issue, but it is a second issye mentioned
that, the only one reminding.
|
|
|
|
Collections are now identified by their pointer.
Also had to correct TSE_IS_REAL_ID to fix undefined behavior on undo.
|
|
|
|
Reordering is disabled for now. Link, unlink and override operators
are only available while in "Active Layer" mode, not in "All
Collections".
|
|
Adds a new outliner display mode "Collections" which draws the active
collection. We might want to rename it to "Active Collection" if we don't
plan to support showing other collections there.
Also added the buttons for restricting visibility and selectability.
@dfelinto, code in restrictbutton_collection_hide_cb and
restrictbutton_collection_hide_select_cb is duplicated from
rna_LayerCollection_hide_update and
rna_LayerCollection_hide_select_update, maybe utility functions would be
handy for this?

This reverts commit 5aa19be91263a249ffae75573e3b32f24269d890 and b4a721af694817fa921b119df83d33ede7d7fed0.
Due to postponement of particle system rewrite it was decided to put particle code
back into the 2.8 branch for the time being.

Some little UI polish to get familiar with outliner code (but also because it's a useful feature). Committing to blender2.8 branch but can also port to master (2.7) if wanted.
This basically causes the mouse hovered element to be highlighted. Contrast of the highlight should be fine, even with a non-default theme. Also did some minor cleanup.

To reproduce the crash:
* Add some shapekeys to default cube.
* Add at least on driver (can be default empty one) to a shapekey value.
* **Make this driver visible in Outliner**.
* Delete all shapekeys.
* Undo.
* Crash.
Root of the issue is outliner reading code in `blo_lib_link_screen_restore()`,
which would try to `restore_pointer_by_name()` for all `TreeStoreElement->id` pointers.
Thing is, those id pointers are not always IDs, they can be animdata, sequence, RNA struct/property...
That's really not so great design, but also has reasons like size of the struct, we have to live with it.
So now:
* TreeStoreElement->type defines are braught back into DNA.
* There we also define a `TSE_IS_REAL_ID` macro to check whether a given TreeStoreElement actually stores an ID pointer or not.
* And in Outliner read code we only try to retore pointers by name for actual ID ones, and set the others to default NULL value.
Also, added clear comment to TSE types that do not store a real ID pointer!

- performance of outliner was low because of unoptimal data structures.
- now it uses BLI_mempool instead of custom mempool and GHash to make searches for duplicates faster.
- also fix undesired behaviour of BLI_mempool_as_arrayN
thanks to Campbell Barton and Lukas Tönne for helping me get a better fix put together.

From description:
One thing with the outliner filter box is it only filters items that
are currently visible. To find what you want you need to manually
expand a few levels so that what you want to find is visible.
This small patch expands items when filtering is done - effectively
turning it into a search.
Currently this does not alter the datablocks view as expanding all
entries takes waaaay tooooo long.
I prevent the expansion of RNA entries for userprefs which prevents
infinite recursion but the datablocks list is just too big for this
approach. I think it would need a custom outliner_build_tree for a
full search.

this can be brought back as a new space if someone decides to

This also fixes remaining issues with the outliner tree open
