Make the UI API more consistent and reduce confusion with some naming.
mainly:
- API function calls
- enum values
some internal static functions have been left for now
Added a special notifier now NC_WM|ND_UNDO in order to deal with such cases
and now compositor/image will refresh when undo happens.
There are much more ways to fail compo to update the resul, like undoing
while it's not visible and so, but as mont29 said -- let's at least fix
obvious crap in the workflow.
This is needed for popups to chance state once activated,
currently it makes use of operators `check` callback, after values are modified,
as the file selector does already.
Issue here is that upon entering sculpt mode, the mesh (and the object
mode) is stored in global undo. Now made the code similar to edit mode,
but since we don't really have any operator to push, this is just
ignored for now.
I have tried just disabling the sculpt toggle operator undo flag but
this didn't work due to the nature recursive of the operator calls
Undoing nodes that do not belong to the current object will cause the
saved bmesh log entry to be reverted instead. This entry can belong to
another object though.
This is easy to fix by enforcing name matching (this was borrowed by
edit mode but can definitely be improved) between current object name
and undo node name and deleting older entries.
However there are complications. Deleting dyntopo entries in this way
can leave a brush stroke as first dyntopo log entry. This can present
issues if we attempt to delete that entry since it's deleted mesh
elements may now have had their ids (which would still be valid at the
time) cleaned up. This can result in crashing if we attempt to resculpt
on the mesh. To fix this I have disabled releasing the deleted entries.
This entanglement between bm_log and undo is quite volatile but I hope
the system works better now.
Also minor cleanup, fix unneeded check warning
Issue fixed by:
* Not having constant width for all columns, but adapt each to its content's width;
* Adapting undo's menu height to undo list length (so that we never have more than three columns).
It is still possible to get issues in extreme cases (small screen, high DPI size,
long op names everywhere...), but this should now be rare corner cases.
Also fixes a minor glitch with undo menu (first column had one item less than the others...).
history operator (Ctrl + Alt + Z).
This will only show paint operations now while in an image paint mode.
The caveat is that user can delete previous paint operations too (even
on images not on the canvas currently) so it needs some care. This is
consistent with regular undo behaviour though.
Sculpting also suffers from lack of Undo history support, this will be
added in a separate commit.
draw mode. This happens because it uses node data structures in threads, now
it does same as preview render, which is to immediately stop the render thread
when e.g. deleting nodes.
internal viewport rendering. Lots of tweaks here, mainly:
* Stop 3D viewport render and free database before undo.
* Accumulate update flags rather than replace them each time it rerenders, to
avoid previous updates getting lost.
* Don't check against Render struct view parameters for changes, those are set
in the job thread which might not run before the next update call.
Forward enum declaration is a bad idea, especially for C++ which requires
enum specification to dteermine which data type to use to store it.
Alternative would be to not use enum as an arument and pass it as int,
but actually would rather be strict on typing -- using explicit enum
as parameter type helps understanding the code and prevents possible
mistakes when using the function.
Global undo/redo now clears the local undo editmode stack entirely.
Error goes back to the 2.3 days, when undo was added.
Global undo refreshes the entire internal database, so all ID pointers get invalid.
This cases editmode undo storage to fail, if it uses ID pointers as well.
The error was that for any Mesh undo stack, a single global undo would make the
mesh stack corrupt. Back in edit mode, on undo you'd lose assigned texture images,
or get bad crashes.
The downside is that people expect this to work... it's a fun feature to maintain
stacks separately. Having this instable is not acceptable though. Needs quite some
redesign work to solve it (like Dalai's kill-the-tface project :)
This means you can for example, uv unwrap in quad-view and change settings in the toolbar without defaulting back to the first quad-view region available.
This may be displayed to the user later, for now this is set on executing registrable operators.
Bug was in fact that the options for this operator couldn't be accessed (unless you knew to press f6), now the redo panel sets the window area before polling.
Now other operators that use the window region will show settings too.
Undoing/redoing in sculpt and other paint modes should only use the
mode-specific undo, not global undo. It is now consistent with edit
mode and avoids tricky interaction between the two systems.
--debug
--debug-ffmpeg
--debug-python
--debug-events
--debug-wm
This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.
problem was that BMesh had tessellation call when undo pushes were called.
if python called an operator with no undo push, tessfaces would not be created.
fix this by making it the responsibility of each editmesh operator to re-tessellate, as it is with notifiers and depsgraph.
added EDBM_update_generic() function to add notifier, tag for depsgraph update and optionally re-tessellate.
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
changes
* undo now checks screen jobs only, was checking all jobs before so a material preview could make an undo fail.
now this is only limiteds for render/fluid bake/bake.
* the redo UI is now disabled when screen operators run.
