- 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.
- 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.
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.
- Updated InputNavigation CVar to support 1: keyboard navigation, 2: gamepad navigation and 3: keyboard + gamepad navigation simultaneously.
- Added ImGui interoperability utilities mapping gamepad input events to values in ImGui navigation inputs array.
- Added to ImGui Input State support for gamepad navigation inputs.
- Refactored ImGui Input State to keep consistent interface for keyboard, mouse and gamepad updates.
- 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.
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.
- 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.
