The previous commit surfaced a bug introduced in rBab4654cdfe8f in which
a boolean wasn't initialized to false.
|
|
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.
|
|
Prefix a return parameter with `r_` to follow the style guide. No
functional changes.
|
|
Move the logic for determining if the item at a given x position is an
icon into the function. This is used for determining selection over an
icon, and will be used in a later commit for checking for hover over an
icon. No functional changes.
|
|
According to feedback the outliner to properties editor tab switching
was annoying when it always changed tabs on selection, especially for
selecting individual objects. This limits the tab switching behavior to
only when the icons in the outliner are selected.

This adds an invert toggle for the outliner object state filters.
There are some cases where we want a filter for invertable states (Selected,
Unselected) and having a single toggle to invert the filter reduces the
number of separate filter types needed. This removes the "Hidden" filter
which can now be replicated with an inverted "Visible" filter.

During some operators like rotate in grease pencil edit mode the
hierarchy lines in the outliner would draw twice as thick. Set the width
before drawing the lines in the outliner.

After rB452a1c7b3838 there were still a few cases where the old
collection icon was used in the interface. Replace these with the new
filled collection icon.

This commit makes the property editor switch to the physics tab instead
of the modifier tab when selecting physics modifiers. Since the modifier
isn't visible then, it's confusing to change the expansion, so this commit
also disables the modifier expansion for these modifiers.

It's odd to include a C++ header (".hh") in C code, we should avoid that. All
of the Outliner code should be moved to C++, I don't expect this C header to
stay for long.

"View" leads to weird names like `TreeViewViewLayer` and after all they are
specific to what we call a "display mode", so "display" is more appropriate.
Also add, update and correct comments.
|
|
See https://developer.blender.org/D9499.
* Use C++17 nested namespaces.
* Use `_` suffix rather than prefix for private member variables.
Also: Simplify code visually in `tree_view.cc` with `using namespace`.
|
|
See https://developer.blender.org/D9499.
* Turn functions into member functions (makes API for a type more obvious &
local, allows implicitly sharing data through member variables, enables order
independend definition of functions, allows more natural language for
function names because of the obvious context).
* Prefer references over pointers for passing by reference (makes clear that
NULL is not a valid value and that the current scope is not the owner).
* Reduce indentation levels, use `continue` in loops to ensure preconditions
are met.
* Add asserts for sanity checks.
|
|
See https://developer.blender.org/D9499.
Also:
* Add `space_outliner/tree/common.cc` for functions shared between display
modes.
* I had to add a cast to `ListBaseWrapper` to make it work with ID lists.
* Cleanup: Remove internal `Tree` alias for `ListBase`. That was more confusing
than helpful.
|
|
See https://developer.blender.org/D9499.
Also remove unnecessary forward declaration.

* Add comments to explain the design ideas better.
* Follow code style guide for class layout.
* Avoid uninitialized value after construction (general good practice).
|
|
See https://developer.blender.org/D9499.
* Use `blender::Map` over `GHash`
* Use `blender::Vector` over allocated `ListBase *`
Benefits:
* Significantly reduces the amount of heap allocations in large trees (e.g.
from O(n) to O(log(n)), where n is number of objects).
* Higher type safety (no `void *`, virtually no casts).
* More optimized (e.g. small buffer optimization).
* More practicable, const-correct APIs with well-defined exception behavior.
Code generally becomes more readable (less lines of code, less boilerplate,
more logic-focused APIs because of greater language flexibility).

* Turn functions into member functions (makes API for a type more obvious &
local, allows implicitly sharing data through member variables, enables order
independend definition of functions, allows more natural language for
function names because of the obvious context).
* Move important variables to classes rather than passing around all the time
(shorter, more task-focused code, localizes important data names).
* Add helper class for adding object children sub-trees (smaller, more focused
units are easier to reason about, have higher coherence, better testability,
can manage own resources easily with RAII).
* Use C++ iterators over C-macros (arguably more readable, less macros is
generally preferred)
* Add doxygen groups (visually emphasizes the coherence of code sections,
provide place for higher level comments on sections).
* Prefer references over pointers for passing by reference (makes clear that
NULL is not a valid value and that the current scope is not the owner).

This introduces a new C++ abstraction "tree-display" (in this commit named
tree-view, renamed in a followup) to help constructing and managing the tree
for the different display types (View Layer, Scene, Blender file, etc.).
See https://developer.blender.org/D9499 for more context. Other developers
approved this rather significantly different design approach there.
----
Motivation
General problems with current design:
* The Outliner tree building code is messy and hard to follow.
* Hard-coded display mode checks are scattered over many places.
* Data is passed around in rather unsafe ways (e.g. lots of `void *`).
* There are no individually testable units.
* Data-structure use is inefficient.
The current Outliner code needs quite some untangling, the tree building seems
like a good place to start. This and the followup commits tackle that.
----
Design Idea
Idea is to have an abstract base class (`AbstractTreeDisplay`), and then
sub-classes with the implementation for each display type (e.g.
`TreeDisplayViewLayer`, `TreeDisplayDataAPI`, etc). The tree-display is kept
alive until tree-rebuild as runtime data of the space, so that further queries
based on the display type can be executed (e.g. "does the display support
selection syncing?", "does it support restriction toggle columns?", etc.).
New files are in a new `space_outliner/tree` sub-directory.
With the new design, display modes become proper units, making them more
maintainable, safer and testable. It should also be easier now to add new
display modes.

- scrolling would be restricted (usually, if the object to be renamed is
in view, this prevents scrolling away without finishing the rename
operation)
- renaming by typing and confirming with Enter was not possible (you
would have to escape, scroll to the object and use F2 again)
- other shortcuts like A and H are still active instead of being handled
as text input
Avoid all these issue by forcing the item into view using
outliner_show_active / outliner_scroll_view.

Scrolling to an item after opening relevant parents can go wrong if said
parent e.g. the last in the list [as in: then the Outliner does not
scroll down all the way]
It stems from the fact that 'region->v2d.tot.ymin' is not up-to-date in
outliner_scroll_view after outliner_show_active opens up parents, 'tot'
will only update on a redraw.
Now calculate the trees height on the fly using
'outliner_tree_dimensions()'.

Selection should be possible from the left gutter in object mode. When
in other modes the mode column displays icon buttons which should be
prioritized for selection only in those modes.

Caused by rBb077de086e14.
Not entirely sure why this was rebuilding the tree prior to above
commit, but sending an ND_OB_SHADING notifier is appropriate (and also
what the Outliners listener listens to).

When editbones were selected from the Outliner (and they were connected
to a parent) with the 'Sync Selection' option turned ON, they could not
get duplicated.
For duplication to work, the (connected) parent bone's tip also has to
be selected [which was not the case when selection is done from the
Outliner under above circumstances]. The reason being that
armature_duplicate_selected_exec ->
ED_armature_edit_sync_selection clears the BONE_ROOTSEL flag if the
parent bone's BONE_TIPSEL is not set.
Caused by rB71eb65328078 btw.
The correct "parent-tip-selection" would actually happen in activation
- `tree_element_active_ebone`
-- `tree_element_active_ebone__sel`
but for 'Sync Selection' this happens [also] in
- `outliner_sync_selection_from_outliner`
-- `outliner_select_sync_to_edit_bone`
which did not do the "flushing" to the parent bone's tip
Now use existing dedicated function for this.

Ensure that When checking "Hide in Viewport" option for a collection
that child objects are drawn grayed out for consistency with the
"Disable in Viewports" toggle.
For checking an object visibility in the viewport the flag
BASE_VISIBLE_VIEWLAYER should be used instead of BASE_VISIBLE_DEPSGRAPH
because the latter ignores viewport visibility.

Switching modes no longer adds multiple undo steps
from a user perspective.
|
|
For edit/pose modes clicking in the mode-column would include other
selected objects (besides the active object), causing other objects to
remain in the mode even though Control wasn't held.
Also replace `ED_object_mode_generic_exit(...)` on all objects with a
single call to `ED_object_mode_set(...)` so switching modes will only
exit the current mode, leaving objects in other modes unchanged.

When outliner datablocks are selected, switch to the corresponding tab
for that datablock in properties editors. Only properties editors
that share an edge with the outliner will change tabs.
Additionally, when modifiers, constraints, and shader effects are
selected from the outliner, the panel will be expanded in all properties
editors.

For objects with shared data, it makes sense to show the mode icon for
every object sharing the same data if one of them is in edit mode.
This also disables the "extend" functionality in this case, because
being in edit mode for multiple objects with the same data isn't
supported.

One can now use 'make local' from the Outliner or the 3DView to also
