- 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.
Using ImGui to draw cursor helps to reduce visual error between mouse cursor and position in ImGui. But it has been reported that this works really bad when frame-rate drops and becomes unusable below ~20 FPS. Taking that into account hardware cursor seems like a better default option. Old behaviour can be enabled with ImGui.DrawMouseCursor console variable.
- Removed usage of per-vertex ClipRect.
- Replaced usage of GSlateScissorRect with new FSlateWindowElementList::PushClip/PopClip functions.
- Defined WITH_OBSOLETE_CLIPPING_API to switch to old implementation for older engine versions.
- 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.
- Different handling of 'Esc' key. If ImGui has active items then it is used to exit edit mode, otherwise it is passed to editor to cancel session.
- Suppressing keyboard input when console is opened and retaking it when it is closed.
- Fixed issue with losing input when console is closed.
- Added ImGui.Debug.Widget console variable to enable/disable widget state debugging.
- Added ImGui ImGui debug for widget state.
- Added logging for widget state transitions.
- 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).
- Separate modifier keys interface and data from generic keys.
- Cleaned interface to better differentiate between full reset and clearing update data.
- Fixed bug in code clearing characters.
- Added ImGui Input State to collect and store input updates.
- Changed Slate ImGui Widget to handle Slate input events and store them in input state.
- Changed ImGui Context Proxy to copy input state to its context.
- Added ImGui Module Manager that that implements module logic and manages other module resources.
- Added Texture Manager to manage texture resources and maps them to index that can be passed to ImGui context.
- Added Context Proxy that represents and manages a single ImGui context.
- Added Slate ImGui Widget to render ImGui output.
- Added ImGui framework source directory.
- Added to ImGui module include paths pointing to ImGui source directory.
- Added to ImGui module implementation file that includes ImGui source code to be built as part of the module.
