Detailed Description

ICanvasEditor adapter for ImNodes-based editors (VisualScript)

Wraps ImNodes::BeginNodeEditor/EndNodeEditor with standardized interface

@design

• Minimal wrapper around imnodes
• Exposes pan control via EditorContextGetPanning/EditorContextResetPanning
• Zoom is read-only (always 1.0f - imnodes doesn't support zoom)
• Coordinates use grid space (pan-independent storage)
• Grid delegated to CanvasGridRenderer with Style_VisualScript preset

@usage // In VisualScriptEditorPanel::RenderCanvas() m_canvasEditor = std::make_unique<ImNodesCanvasEditor>("VisualScript", canvasScreenPos, canvasSize);

m_canvasEditor->BeginRender(); { // Render nodes using ImNodes API as usual ImNodes::BeginNode(nodeId); // ... node content ImNodes::EndNode(); } m_canvasEditor->EndRender();

@compatibility C++14
