This will override all linked data-blocks in the tree branch leading to
the selected one.

Code is mature enough now to not need this anymore, people who do not
want to use liboverrides can just not create them.

Duplication and deletion code of modifiers was totally wrong for
particle system, that special weird thing needs its own custom
management.
Note that for now I chose not to duplicate the particle settings ID when
duplicating the modifier...

No functional changes. Convert all C++ style comments to C comments.
Also capitalize and add full stops.
The comments themselves were not cleaned up. Some could be removed or
reworded.
|

No functional changes. Remove commented calls to extern_set_butspace
and unused text activation code.
|
|
No functional changes. Use _fn instead of _cb.

This addresses warnings from Clang-Tidy's `readability-else-after-return`

Pan the view when dragging elements near the borders. This uses the same
operator that scrolls the region during modifiers drag and drop.

Previously it was not possible to tell appart a linked data-block from its
override copy. In fact you couldn't tell appart any data-blocks with the same
name (which is possible with linking).
Now we show the library state icon as we do for data-blocks in other display
modes.

Rather than a `L` (linked), `O` (overridden) or `M` (missing) prefix for the
name, show the existing library status icons. See D7999 for screenshots.
Note that when using preview icons, or if the search menu contains items with
own icons (e.g. brush icons), we still fallback to the prefix solution.
Zero or fake user is still indicated with a prefix.

Steps to reproduce were:
* Load factory settings
* Link any library
* Change to "Blender File" display mode in Outliner
* Enable filtering
* -> Assert fails
This may have had further side-effects for linked IDs.
Checked with Bastien, the NULL-check seems reasonable. It was initially there
but removed in d74f9c4b7b4f.
Fine to backport.

Using 'name' for the full path of a file reads badly,
especially when id.name is used in related code.
|
|
Make it clear that this is the absolute path,
allow the 'name' to be renamed to 'filepath'.
Rename is safe since this is only for run-time.

View2DScrollers used the memory manager to allocate memory. This isn't a
problem but in a upcoming change the scrollers will be drawn more often
than it used to (See {D8066}). To limit the number of allocations and
frees this patch will use the stack for allocation.

The icons for toggling fake users on orphan datablocks in the outliner
were drawn as the quit and x icons instead of the fake user icon. This
changes to the correct icon, and removes the redundant "F" column.

No functional changes. Don't use walk_element now that the walk element
flag is removed.
|
|
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.
|
|
No functional changes. The outliner selection operators shared many
different functions for selection, activation, mode toggling, and other
actions, but the code paths were not always clear, making any changes
difficult.
This cleans up the code and uses outliner_item_select() as the base
function for selection, activation, mode toggling between the different
selection operators. It also prepares for future features and fixes.

Steps to reproduce were:
* From factory settings, change Outliner Display Mode to "Blender File"
* Open "Screens" item, make sure all listed screens are visible
* Open Preference window, close it
* Mouse hover the outliner -> crash
Fix is to force an Outliner tree rebuild when closing screens.

The lookup to find the hovered Outliner tree element would possibly check
children that can be skipped with a simple check.
I experimented with various ways to avoid work in this lookup. This one is
simple and reliable, which others wouldn't have been afaics. Plus, there's not
much performance to be gained here anyway.
|
|
In big files, the Outliner would have a noticeable lag when opening or
collapsing items. That was because the entire tree was rebuilt, which isn't
actually needed in most cases. So we avoid it where possible now.
|
|
When leaving the Outliner's area, the highlight would be removed and cause a
full rebuild of the tree. This caused a noticable lag in bigger files.

Pose groups previously showed a dot icon. Now it draws the correct icon.

Previous commits to fix parent selection introduced incorrect behavior
when selecting objects linked to multiple collections. The clicked
object would be selected, but also the first listed object in the tree
would be selected.
Instead of always searching for a parent object to select, only search
back when the selected element is not an ID_OB. This prevents multiple
selection of objects linked to multiple collections.
|
|
Main change from user side, besides that all pointers should now be
properly remapped to new IDs, is that linked objects are no longer
preserved when doing a full copy of scenes.
Will open a task to check whether we actually still want that behavior
(and re-code it in a more correct way then).
This is the main part of work done here, it aims at uniformizing and
sanitizing that 'deep copy' process for supported IDs (currently scenes,
collections and objects).
Note that there will be more follow up commits after that one, but this
should be the most risky and changing one.

This resolves T73673 by allowing delete hierarchy in all outliner view
modes. It also unifies the collection and object hierarchy delete into a
single operator like in rBae98a033c856. This makes it easier to delete
all selected collection and object hierarchies at once.
This also removes the old object delete hierarchy code in favor of the
batch delete code which has been default for over a year.

It makes no sense to deep-copy a collection and not also copy its
children collections... Parameter was not used anymore anyway.
So now this duplicate function will always at least deep-duplicate all
of its children collections, recursively.
|
|
|
|
When linking or overriding an instanced collection, the new collection item in
the Outliner is now un-collapsed by default.
Linking and overriding is typically used in production scenes, where
collections tend to contain many items (children, grand-children, etc.). If all
collections in that hierarchy are expanded by default, the Outliner gets
flooded with items. So users ended up manually collapsing the collections.
Part of T76555.

Add selection syncing for object add named (e.g. drag and drop from
outliner to 3D view), outliner right click (a sync when the context menu
is cancelled), and for object selection from Python.

Allow setting drivers and keyframes for the bone visibility restriction
icon in the outliner. Before the button was a simple icon button, but it
is now connected to the RNA property to show the driven or keyframed
state.
Also when hiding a bone from the outliner it would be deselected, but
from the properties editor it would remain selected. This moves the
deselection to the RNA update function to ensure the bone is always
deselected.

Bug was actually in outliner code, paste operator would not generate any
undo step...
This was not correct ever, but with new undo code this has become a
critical issue, it cannot survive a situation where current main data
has been changed without a proper undo push.
This illustrates again how much of a catastrophic mess the 'tools'
callbacks of the outliner are currently, it has already caused us quiet
some pain in the past, and will keep doing so until this is fully
sanitized am afraid.
Would strongly suggest getting rid of thosw nasty mix of custom
callbacks requiring manual undo pushes, I do not see the added value of
this compared to regular menus calling regular operators. It only adds
confusion and extra code for nothing...

Right now:
- drag-drop in the Outliner prevents dropping inside linked collections
- drag-drop in the Outliner allows dropping inside overridden
collections (should not be the case)
- `Object Properties` > `Collections` panel allows to add to overridden
collection (should not be the case)
- `Object Properties` > `Collections` panel filters out non-local
collections (so adding to linked collections is forbidden)
- `bpy collection.objects.link()` allows to add to linked collections
(should not be the case)
- `bpy collection.objects.link()` allows to add to overridden
collections (should not be the case)
While this might be supported in the future for overriden collections,
these cases should not be allowed atm. since objects get lost on file
reload.
Note: for the case of the `Object Properties` > `Collections` panel,
this could be improved further to filter out overridden collections as
well.

Overriding datablock should never have an editable name.
This also moves the check for linked/overridden datablocks above the
check for master-collection (otherwise a linked/overriden collection
could still be renamed)

For now the "Simulation" modifier only exists for point cloud objects, because
we need this for the particle system. Right now, the modifier is doing nothing.
There is a new `DEG_add_simulation_relation` function that is used
by the modifier to make sure that the simulation is evaluated before
the modifier is executed.
