- Converts type assertions to use inference via discriminated unions
- Removes the LayoutElement class (only used by node slots, and recently
reduced to a single function)
- Splits `boundingRect` property out from `Positionable` interface
- Slots now use the standard `boundingRect` property
- Perf improvements / Removes redundant code
https://github.com/Comfy-Org/ComfyUI_frontend/pull/3323
Some widgets are only used for display purpose (The preview image
widget), their value shouldn't be serialized into the workflow. This PR
adds a flag to allow widget to skip value serialization.
This PR is the litegraph side change necessary for widget sockets
feature in ComfyUI_frontend. Changes include
- Add readonly `Widget.computedDisabled` property for getting the
computed disabled state. When the associated socket is connected, the
widget is disabled
- Dynamically show the associated socket when
- the mouse is over the widget
- the slot is valid during link drop
- the slot is connected
- Removes the legacy widget drop behavior
Ref: https://github.com/Comfy-Org/rfcs/pull/9
Currently widget needs to get access to `LGraphCanvas` instance to know
whether the canvas is rendering in low quality (Zoomed out). Usually
canvas object is obtained from `ComfyApp` instance.
This PR passes the lowQuality value to `IWidget.draw` to decouple the
dependency on `LGraphCanvas`.
- Updates UUIDv4 generator
- Adds a unique id & revision support to graphs
- `revision` to be incremented downstream (e.g. on save)
- `id` automatically assigned if not provided
- Fixes root cause of minor in-memory-only corruption when deleting
reroutes from output slots
- Already automatically corrected via serialisation
- If `reroutes` or `links` are empty arrays, removes them from newer
object-based serialised output entirely
- Minor refactors
- Removes unused code
- Fixes some serialisation types
- Adds `ReadonlyLinkNetwork` interface
Resolved issues with history due to merges, opened a new pull request.
A more visual widget that the usual number/slider. Differentiates itself
from the functionality of a slider by not setting the value on click,
only stepping, emulating an actual knob.
- Left/Right takes 1 step at a time
- Up/Down moves 1% or 1 step, whichever is larger
- Move + Shift moves by 10% or 1 step, whichever is larger
This also includes a fixes to some size logic.
- [x] ~~Still missing being able to drag the knob itself, as the
clicking of the widget is not recognized if it's outside of where a
normal height widget would be.~~

- Prefer comments above lines over end-of-line comments
- Makes auto-formatting easier
- Subjective, but it is generally easier to read in JS
- Standardises JSdoc format
- Auto-fixes for many issues (applies on save w/ESLint extension)
- Part of effort to convert LGraphNode to TS strict
- Adds some small runtime changes - no impact expected, but it is
possible
- Runtime changes are in separate commits from compile-time type changes
- Risk of downstream impact is low

Replaces previous impls. which only worked on some items, and were triggered when unexpected e.g. clicking a node that hadn't been moved.
Update test expectations
* Narrow TS types - readonly

* nit - Clean up legacy accessors
Marks as deprecated

LGraphNode.getWidgetOnPos

* Rewrite canvas mouse handling
- Rewrites most pointer handling to use CanvasPointer callbacks
- All callbacks are declared ahead of time during the initial pointerdown event, logically grouped together
- Drastically simplifies the alteration or creation of new click / drag interactions
- Click events are all clicks, rather than some processed on mouse down, others on mouse up
- Functions return instead of setting and repeatedly checking multiple state vars
- Removes all lines that needed THIRTEEN tab indents

No longer mutates nodes when copying

Set default centre marker to arrow
* Add module export: LinkMarkerShape

Moves last_link_id, last_node_id and creates same for group and reroute
