From 881ff67fe2472a63c1bc700610cae8d8f9cf56de Mon Sep 17 00:00:00 2001 From: Benjamin Lu Date: Sat, 6 Sep 2025 12:43:17 -0700 Subject: [PATCH 1/8] [refactor] Use getSlotPosition for Vue nodes in link rendering MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace direct node position calls with getSlotPosition utility when Vue nodes mode is enabled. This ensures consistent slot positioning across the canvas rendering system. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/lib/litegraph/src/LGraphCanvas.ts | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/src/lib/litegraph/src/LGraphCanvas.ts b/src/lib/litegraph/src/LGraphCanvas.ts index 9e7ef226f..e0e0031d9 100644 --- a/src/lib/litegraph/src/LGraphCanvas.ts +++ b/src/lib/litegraph/src/LGraphCanvas.ts @@ -6,7 +6,6 @@ import { type LinkRenderContext, LitegraphLinkAdapter } from '@/renderer/core/canvas/litegraph/litegraphLinkAdapter' -import { getSlotPosition } from '@/renderer/core/canvas/litegraph/slotCalculations' import { layoutStore } from '@/renderer/core/layout/store/layoutStore' import { CanvasPointer } from './CanvasPointer' @@ -5560,9 +5559,7 @@ export class LGraphCanvas const link = graph._links.get(link_id) if (!link) continue - const endPos: Point = LiteGraph.vueNodesMode // TODO: still use LG get pos if vue nodes is off until stable - ? getSlotPosition(node, i, true) - : node.getInputPos(i) + const endPos = node.getInputPos(i) // find link info const start_node = graph.getNodeById(link.origin_id) @@ -5572,9 +5569,7 @@ export class LGraphCanvas const startPos: Point = outputId === -1 ?
