Add toolbar to sequencer regions.
A bit of refactoring has to be done in RNA space.
Currently there is only cut tool implemented to serve as template for
anybody who would like to add more.
This defaults to selection when not using a gizmo.
The previous behavior to drag anywhere can be set in the tool settings
or by selecting the fallback tool (Alt-W).
See: T66304
Implement T66304 as an experimental option,
available under the preferences "Experimental" section.
- When enabled most tools in the 3D view have a gizmo.
- Dragging outside the gizmo uses the 'fallback' tool.
- The fallback tool can be changed or disabled in the tool options
or from a pie menu (Alt-W).
Changing the workspace or mode from one window may need to change the
active tool in another window since two different workspaces
may share an object.
This wasn't working with multiple windows,
WM_toolsystem_do_msg_notify_tag_refresh could use a workspace
from a different window to the screen that owned the area.
Instead of fixing, remove these since they aren't needed anymore
since changing modes now refreshes the tool system.
This makes Shift and Ctrl work properly to extend and subtract selections.
This also moves Cut Links to Ctrl-RMB, which doesn't conflict with the selection tool.
In 2.7x UV sculpt was a kind of sub-mode
(a toggle with it's own key-map & drawing code).
Move this to an operator that uses the tool-system,
this simplifies internal logic, especially brush selection
which now matches sculpt and other paint modes.
- Remove toggle used to enable uv sculpt.
- Expose the brush, which was already used but there was no way to
select different brushes.
- Make UV sculpt use paint paint tool slots
(using brushes how all other paint mode currently do).
- Move UV Sculpt keymap to the tools keymap.
- Remove Q to toggle UV sculpt mode,
S/P/G keys to switch tools.
Prepare for exposing tool registration to the Python API.
- Generated tools can use their own prefix so naming collisions
won't happen between hard coded & generated tools.
- Add-on authors can use the add-on name as a prefix.
Currently the names match, renaming will happen next.
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
- Key-map items properties now override tool-options
so modifier keys can have different behavior to the default action.
- Box & circle select now have `wait_for_input` properties
instead of detecting this based on selection options being set or not.
This relied on the key-map setting properties which may need to be
initialize from the tool settings.
For users that want the 2.7 LMB keymap behavior, this provides a way of
working without tools interfering. For RMB select this operator is quite
redundant with the Cursor tool, we may have to find a solution for that.
Note that we also might later add transform tweak to the transform tools,
when nothing is selected. But this is important for existing users who
preferred the existing workflow.
