- Adaptive size is controlled by the ImGui Widget, which passes it from the view-port to the context proxy.
- Context only copies display size that is set from the outside.
- Removed feature dependency from the manager.
- Disabled move semantics in FImGuiContextProxy and removed code related to moving ImGui context.
- Changed FImGuiContextManager to store proxies as unique pointers.
- Added to SImGuiWidget and FImGuiInputHandler handling of touch started, move and ended events.
- Events are passed to FImGuiInputState to be copied to ImGui IO as a mouse move and left button down.
- Added one frame lag between touch ending event and ending processing, to allow ImGui handle mouse-up event.
Merged 4 commits fixing build errors when compiling this as an engine plugin:
- Changed include directives to use full paths (ex. <ICursor.h> -> <GenericPlatform/ICursor.h>).
- Added categories to FImGuiKeyInfo properties (required for all blueprint exposed types in engine plugins).
- Added explicit configuration of PCHUsage (without that it is assumed to be UseExplicitOrSharedPCHs in engine plugins and UseSharedPCHs in game ones) - amended to work also in the older engine versions.
- With the mouse sharing enabled, SImGuiWidget can update mouse position without enabling hit-tests. Actual input mode depends whether mouse cursor is hovering any ImGui window or not.
- Added to context proxy interface to read whether that context has mouse hovering any window.
- Added boilerplate code to support mouse sharing settings, properties and commands.
- Moved responsibility for updating input state from the widget to the input handler.
- Changed the widget to fully delegate input events to the input handler and only manage its own input state.
- Changed the input handler interface to allow handling of all the necessary input events.
- Changed the input handler interface to use FReply as a response type and removed obsolete FImGuiInputResponse.
Moving input state to context proxy decouples it a bit from a particular input source and although not used right now, it allows multiple sources to send input in parallel.
- Removed mouse status update.
- Removed mouse notifications.
- Removed unused function to copy modifier keys on mouse events (key down/up versions are still in use).
Current implementation of the IsInGameThread() doesn't make exceptions for a loading thread and lazy initialization of the Unreal resources ensures that plugin doesn't do any work before the game starts.
- 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.
- Added SImGuiLayout to resets layout and house SImGuiWidget.
- Module manager creates SImGuiLayout instead of SImGuiWidget (eventually it should be replaced with a higher level object, like AHUD).
- Reworked ImGui canvas dragging and scaling and moved to SImGuiCanvasControl.
- Removed dependency on ImGui internal cursor data. New presentation is cleaner and doesn't use cursor data.
- Rendering code could be simplified after layout reset provided by SImGuiLayout.
- SImGuiWidget still handles input, rendering of ImGui draw data and activation of SImGuiCanvasControl.
- All widgets are in own subfolder.
Instead of throwing assertion unsupported keys are mapped to 0, what guarantees that ImGui key map is always initialized and unsupported keys mapped to index that cannot be reached from key input events that have non-zero key codes.
- Divided ImGui settings into UImGuiSettings persistent object and FImGuiModuleSettings proxy that provides interface for other classes and handles delayed loading of UImGuiSettings.
- Removed from FImGuiModuleProperties and FImGuiModuleCommands direct dependencies on UImGuiSettings.
- Simplified FImGuiModuleProperties making it more robust when moving data after hot-reloading.
- Inverted binding logic by injecting FImGuiModuleProperties and FImGuiModuleCommands into FImGuiModuleSettings and letting it take care of synchronization. Dependencies are setup by module manager.
- Added to module manager FImGuiModuleSettings and interface to access it.
- Cleaned interface of FImGuiInputHandlerFactory and removed direct dependency on settings.
- Added properties defining whether keyboard or gamepad input should be shared between ImGui and game.
- Added interface and commands to dynamically change introduced properties.
- Updated ImGui Input Handler to base default input responses on sharing properties.
- 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.
Note that this commit contains a minor breaking change for custom implementations of UImGuiInputHandler.
- Changed "ImGui.SwitchInputMode" command name to "ImGui.ToggleInput".
- Changed SwitchInputModeKey property in settings to ToggleInput.
- Added temporary mechanism protecting from losing data by moving it from SwitchInputModeKey to ToggleInput and removing deprecated entry from the default config file.
- Renamed UImGuiInputHandler protected function from IsSwitchInputModeEvent to IsToggleInputEvent, so custom implementations of that class may require update.
- Moved property variables to ImGui Module Properties.
- Moved console command to ImGui Module Commands (one for now but more will be added).
- ImGui Module Commands is created by ImGui Module Manager, what means that commands are registered after module is loaded and unregistered when it is unloaded.
- Updated settings to allow more convenient use: Added global pointer to default object and event raised when it is loaded.
- Added common debug config file for module-wide debug symbols and loggers.
- Added IMGUI_MODULE_DEVELOPER symbol to enable or disable module developer mode, that is intended to add additional module debug options hidden from normal usage.
- ImGui Widget debug is only available in developer mode because in normal usage it adds noise to ImGui console variables while not being very useful.
- Merged LogImGuiInputHandler and LogImGuiInputHandlerFactory loggers as they are part of the same feature.
- Renamed LogImGuiInputState to LogImGuiInput.
- 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.
- Changed module type to 'Developer'.
- Added runtime loader that handles automatic module loading in runtime builds (feature can be selectively enabled).
