- Removed code allowing to register game delegates outside of the delegates container.
- Removed unused multi-context delegate that is not part of the container.
- Moved implementation of the DPI scale from context manager to context proxy.
- Passing the DPI scale to the context proxy constructor for the initial setup.
- Removed explicit PCH.
- Fixed includes to compile for all supported engine versions, including non-unity builds.
- Configured build.cs to treat ImGui as an engine module and added stricter compilation rules.
- The old DPI Scale setting was replaced by DPI Scaling Info, which contains information about scale and method of scaling.
- ImGui Context Manager handles scaling in ImGui by scaling all styles, rebuilding fonts using a different size, and raising OnFontAtlasBuilt event.
- ImGui Module Manager uses OnFontAtlasBuilt event to rebuild font textures.
- The update policy in Texture Manager was loosened to update existing resources rather than throwing an exception. This is less strict but it is now more useful since our main texture can now change. The throwing behavior used in the public interface is now handled before calling to the Texture Manager.
- Disabled move semantics in FImGuiContextProxy and removed code related to moving ImGui context.
- Changed FImGuiContextManager to store proxies as unique pointers.
- Added to FImGuiDelegates interface early debug delegates called during world tick start.
- Delegates are called in fixed order: multi-context early debug, world early debug (called during world tick start), world debug, multi-context debug (called during world post actor tick or if not available, during world tick start).
- Removed from build script configuration of debug delegates.
- Added new FImGuiDelegates interface for ImGui debug delegates.
- Added FImGuiDelegatesContainer for ImGui delegates.
- Added code preserving delegates during hot-reloading and moving them to a new module.
- Depreciated old FImGuiModule delegates interface and FImGuiDelegateHandle.
- Delegates registered with depreciated interface are redirected and get benefit of being preserved during hot-reloading. This can be controlled with IMGUI_REDIRECT_OBSOLETE_DELEGATES.
- Added IMGUI_WITH_OBSOLETE_DELEGATES allowing to strip depreciated interface from builds.
- Modified context manager and context proxy to work with FImGuiDelegatesContainer.
- Removed ImGui Module Properties singleton interface and released construction constraints.
- Added ImGui Module Properties to ImGui Module Manager.
- Moved ImGui Demo to ImGui Module Manager.
- ImGui Demo and ImGui Module Commands keep reference to ImGui Module Manager that gives them access to properties.
- Replaced 'ImGui.DebugDrawOnWorldTick' with DRAW_EVENTS_ON_WORLD_TICK_START switch to enforce consistency in project setup.
- Added DRAW_EVENTS_ON_POST_ACTOR_TICK to support post actor tick events (only for UE 4.18 or later).
- Added DRAW_EVENTS_ORDER_WORLD_BEFORE_MULTI_CONTEXT to allow explicitly define order between multi-context and world-context draw events.
- Rules can be configured in ImGui.Build.cs file.
- Upgraded ImGui framework to 1.61 WIP, which adds a few improvements to context management.
- Removed from plugin implementation all the references to default ImGui context.
- Removed from ImGui Context Proxy destructor code switching to default ImGui context (there is no default context and decision is left for a higher level manager when to switch and to what context).
- Added own font atlas that is shared by all contexts and used explicitly to create Slate resources.
- Removed from ImGui Context Proxy workaround that was previously needed for copying cursor data to dynamically created contexts.
- Removed explicit saving of context settings before its destruction as this is now handled in ImGui::DestroyContext().
- Reimplemented ImGuiImplementation::GetCursorData() to use new interface.
- ImGui Context Proxy Tick function has been split for Tick and Draw. Both functions may now be called separately from different places but they will be processed only once per frame. This opens possibility to define own mechanisms to trigger draw events and to independently update contexts.
- Multi-context draw event delegate is passed to ImGui Context Proxy during construction rather than as an argument of Tick function.
- To minimise lag between ending ImGui frame and rendering its output, ImGui Widget updates its own context just before painting.
- Contexts without widget (editor, dedicated server) are updated by manager during post-tick event.
- Instead of setting global CurrentContextIndex by ImGui Context Manager, information about context is passed to ImGui Demo as part of a closure.
- Fixed bug in ImGui Demo where inactive contexts were triggering multi-PIE warning.
- Added to ImGui Context Proxy a name that is mapped to ini file set in ImGui context.
- ImGui Context Manager generates unique context names from world type and context index.
- Refactored ImGui Context Manager to have a cleaner separation between editor and non-editor bits.
- Fixed context update rules in ImGui Context Manager.
- Changed widgets management in ImGui Module Manager to allow automatic garbage collection after viewports are closed and manual removal when module is shutting down.
- ImGui Widgets are in full control of communication with context proxies.
- Added basic world context utilities.
- Refactored world context index utilities and replaced ambiguous 'default context index' with 'editor' and 'game' ones.
- Added ImGui Context Manager to create and manage ImGui Context Proxies.
- Changed ImGui Context Proxy to dynamically create context and allow pairing with input state.
- Changed ImGui Module Manager to create one widget per context.
- Changed ImGui Widget to work in different input modes.
- Changed ImGui Input State to allow partial reset (only mouse or keyboard).
