Detailed Description

Polymorphic interface for all graph editor renderers.

Implementations are owned by TabManager via raw pointers (C++14 style). Lifetime: the owning EditorTab deletes the renderer when the tab is closed.

Member Function Documentation

GetCanvasStateJSON()

virtual std::string Olympe::IGraphRenderer::GetCanvasStateJSON ( ) const

inlinevirtual

Get canvas state as JSON string for persistence.

Returns

JSON representation of current canvas state

Reimplemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

Definition at line 96 of file IGraphRenderer.h.

GetCurrentPath()

virtual std::string Olympe::IGraphRenderer::GetCurrentPath ( ) const

pure virtual

Returns the last path successfully loaded/saved, or empty string.

Implemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

GetGraphType()

virtual std::string Olympe::IGraphRenderer::GetGraphType ( ) const

pure virtual

Returns the graph type string, e.g.

"VisualScript", "BehaviorTree".

Implemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

IsDirty()

virtual bool Olympe::IGraphRenderer::IsDirty ( ) const

pure virtual

Returns true when the graph has unsaved changes.

Implemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

Load()

virtual bool Olympe::IGraphRenderer::Load ( const std::string &  path )

pure virtual

Loads a graph from a file on disk.

Parameters

path	Absolute or relative path to the .ats / .json file.

Returns

true on success.

Implemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

Render()

virtual void Olympe::IGraphRenderer::Render ( )

pure virtual

Renders the graph canvas into the current ImGui child window.

Implemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

RestoreCanvasState()

virtual void Olympe::IGraphRenderer::RestoreCanvasState ( )

inlinevirtual

Restore previously saved canvas viewport state Called when tab is reactivated.

Ensures smooth tab switching without losing layout.

Reimplemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

Definition at line 90 of file IGraphRenderer.h.

Save()

virtual bool Olympe::IGraphRenderer::Save ( const std::string &  path )

pure virtual

Saves the current graph state to disk.

Parameters

path	Destination path. If empty, save to the path passed to Load().

Returns

true on success.

Implemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

SaveCanvasState()

virtual void Olympe::IGraphRenderer::SaveCanvasState ( )

inlinevirtual

Save the current canvas viewport state (pan, zoom, etc.) Called when tab is deactivated.

Used to preserve viewport when switching between multiple tabs.

Reimplemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.

Definition at line 83 of file IGraphRenderer.h.

SetCanvasStateJSON()

virtual void Olympe::IGraphRenderer::SetCanvasStateJSON ( const std::string &  json )

inlinevirtual

Restore canvas state from JSON string.

Parameters

json	JSON representation of saved canvas state

Reimplemented in Olympe::BehaviorTreeRenderer, Olympe::EntityPrefabRenderer, and Olympe::VisualScriptRenderer.
