* Implement snap to grid
- Moves positioning logic to LGraph
- Simplifies code
- Adds Pointer API to alt-clone node
- Removes always_round_positions, replaced by always snap to grid (default size is 1 when always snapping)
Fix refator error
* Fix group items snapped without group
* Allow snapping of all items
- Add snapToGrid to Positionable
- Impl. on all types
- Deprecated: alignToGrid is now a wrapper
* Fix test import alias, update expectations
* Prevent desync of before / after change events
Adds ability to perform late binding of finally() during drag start.
* nit - Refactor
* Fix unwanted snap on node/group add
* nit - Doc
* Add shift key state tracking for snap to grid
Private impl., no state API as yet.
* Add snap guides rendering
Nodes, reroutes
* Optimisation - reroute rendering
Fixes exponential redraw
* Add snap guidelines for groups
* Add position rounding feature
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, Doc
* nit - Clean up legacy accessors
Marks as deprecated
* Fix TS type - IContextMenuOptions.scale
* [Refactor] dist2 for use in pointer API
* Add CanvasPointer - API for pointer events
Add TS strict types
Add final click drag distance math
Add option to retain events
* nit - Rename
* nit
* Remove Subgraph - unused & not maintained
* Remove live_mode
Unused, not maintained.
* Update README
Remove live_mode reference
* Update delete selected - include reroutes & groups
* Bypass link menu if alt/shift pressed
* Remove old dragged_node interface
Incomplete impl. - unused.
Superceded by selectedItems
* Fix top/left edge of rectangles not in hitbox
* [Refactor] Match function names to interface names
* Add interface to find widgets by Point
LGraphNode.getWidgetOnPos
* Add widget search param - includeDisabled
* nit - Doc
* 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
* Split middle click out from processMouseDown
* Use pointer API for link menus
* Narrow canvas event interfaces
* Fix canvas event types
Replaces original workarounds with final types
* Refactor - deprecated isInsideRectangle
* Add canvas hovering over state
- Centralises cursor set behaviour
- Provides simple downstream override
* nit
* [Refactor] Use measure functions
* Add double-click API to CanvasPointer
a
* nit - Doc
* Allow larger gap between double click events
* Rewrite double-click into CanvasPointer actions
* Improve double-click UX
Prefer down events over up events
* Add production defaults
* Add middle-click handling
* Remove debug code
* Remove redundant code
* Fix add reroute alt-click adds two undo steps
* Fix click on connected input disconnects
Old behaviour was to disconnect, then recreate a new link on drop.
* Add module export: CanvasPointer
