Walkthrough

This change removes the CURSOR enum from the constants module and replaces all its usages throughout the codebase with configurable cursor properties attached to handler configuration objects (EdgeHandlerConfig, HandleConfig, VertexHandlerConfig) and as an instance property in ConnectionHandler. The changelog is updated to reflect this breaking change. The update ensures that cursor styles for various interactive elements are now configurable rather than fixed, with the relevant cursor values relocated to the appropriate configuration objects or class properties.

CHANGELOG.md (1)

28-32: Changelog documents CURSOR enum removal and config migration
The breaking-changes section correctly notes the removal of constants.CURSOR and points readers to the new locations for cursor configuration. This aligns with the code refactor.

packages/core/src/view/handler/ElbowEdgeHandler.ts (2)

26-26: Approve import of cursor config
Replacing the old CURSOR enum import with EdgeHandlerConfig (and retaining HandleConfig for label sizing) is correct. Both are used in this file (EdgeHandlerConfig for cursors and HandleConfig in redrawInnerBends).

---

69-69: Use configurable cursorTerminal for bend handles
The source and target bend handles now call bend.setCursor(EdgeHandlerConfig.cursorTerminal) instead of a hardcoded enum, centralizing the cursor style.

Also applies to: 87-87

packages/core/src/view/handler/EdgeSegmentHandler.ts (1)

310-310: Apply cursorTerminal from config to segment bends
Both the source and target segment handles correctly use EdgeHandlerConfig.cursorTerminal, replacing the removed enum constants.

Also applies to: 339-339

packages/core/src/view/plugins/SelectionHandler.ts (3)

51-51: Update import for cursor configuration
Removed the CURSOR enum import in favor of EdgeHandlerConfig and VertexHandlerConfig from handler/config.ts, matching the refactor.

---

1031-1031: Use cursorMovable for edges
Edges now use EdgeHandlerConfig.cursorMovable for the move cursor, replacing the old hardcoded CURSOR.MOVABLE_EDGE.

---

1033-1033: Use cursorMovable for vertices
Vertices now use VertexHandlerConfig.cursorMovable for the move cursor, replacing the old hardcoded CURSOR.MOVABLE_VERTEX.

packages/core/src/view/handler/VertexHandler.ts (4)

20-20: Remove CURSOR enum import, retain only NONE
Dropping CURSOR from the constants import and keeping only NONE is correct, since all cursor styles are now provided via HandleConfig and VertexHandlerConfig.

---

235-235: Set selection border cursor from config
Using VertexHandlerConfig.cursorMovable for the selection border cursor aligns with the new flexible cursor configuration system.

---

280-280: Use labelCursor from handle config for label sizers
Applying HandleConfig.labelCursor to the label handle ensures the handle’s cursor style is configurable.

---

296-296: Use cursorMovable for small vertex label handle
For small, non-resizable vertices, the label handle now correctly uses VertexHandlerConfig.cursorMovable, matching the global cursor settings.

packages/core/src/view/plugins/ConnectionHandler.ts (3)

374-379: Appropriate addition of configurable cursor property

This new cursorConnect property helps implement the breaking change from having fixed cursor values in a CURSOR enum to making them configurable, as mentioned in the PR description. The property is well-documented with proper JSDoc.

---

655-655: Correctly updated to use new configurable cursor property

This change replaces what was likely a reference to the removed CURSOR.CONNECT enum value with the new configurable this.cursorConnect property.

---

1241-1241: Correctly updated to use new configurable cursor property

This change replaces what was likely a reference to the removed CURSOR.CONNECT enum value with the new configurable this.cursorConnect property in the method that sets the cursor on the current state.

packages/core/src/view/handler/EdgeHandler.ts (4)

247-247: Correctly updated to use configurable cursor property

Changed from using the removed CURSOR.MOVABLE_EDGE enum value to the new configurable EdgeHandlerConfig.cursorMovable property.

---

296-296: Correctly updated to use configurable cursor property

Changed from using the removed CURSOR.LABEL_HANDLE enum value to the new configurable HandleConfig.labelCursor property.

---

540-542: Correctly updated to use configurable cursor properties

Changed from using the removed CURSOR.TERMINAL_HANDLE and CURSOR.BEND_HANDLE enum values to the new configurable EdgeHandlerConfig.cursorTerminal and EdgeHandlerConfig.cursorBend properties.

---

572-572: Correctly updated to use configurable cursor property

Changed from using the removed CURSOR.VIRTUAL_BEND_HANDLE enum value to the new configurable EdgeHandlerConfig.cursorVirtualBend property.

packages/core/src/view/handler/config.ts (4)

54-77: Well-defined cursor configuration properties for EdgeHandler

These new properties (cursorBend, cursorMovable, cursorTerminal, cursorVirtualBend) provide a configurable way to set cursor styles for different states in the EdgeHandler, replacing the fixed values from the removed CURSOR enum. Each property has appropriate documentation and default values.

---

133-139: Proper implementation of cursor properties in EdgeHandlerConfig

The cursor configurations are properly implemented in the EdgeHandlerConfig object with appropriate default values that match the common cursors used in diagram editing:

• 'crosshair' for bend operations
• 'move' for dragging edges
• 'pointer' for terminal connections

These default values maintain the same user experience as before while making the cursors configurable.

---

182-187: Added label cursor configuration to HandleConfig

This addition to the HandleConfig object makes the label handle cursor configurable, consistent with the overall approach to making cursors configurable rather than fixed.

---

233-237: Added vertex cursor configuration to VertexHandlerConfig

This addition makes the cursor for movable vertices configurable via VertexHandlerConfig, consistent with the overall approach of the PR.
