- Set 'io.BackendFlags |= ImGuiBackendFlags_HasGamepad' + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys.
- For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly.
Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
- BEFORE 1.87, BACKENDS USED TO WRITE TO io.NavInputs[]. This is now obsolete. Please call io functions instead!
- If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing,
with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.

When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
You can read releases logs https://github.com/ocornut/imgui/releases for more details.
- 2024/11/06 (1.91.5) - commented/obsoleted out pre-1.87 IO system (equivalent to using IMGUI_DISABLE_OBSOLETE_KEYIO or IMGUI_DISABLE_OBSOLETE_FUNCTIONS before)
- io.KeyMap[] and io.KeysDown[] are removed (obsoleted February 2022).
- io.NavInputs[] and ImGuiNavInput are removed (obsoleted July 2022).
- pre-1.87 backends are not supported:
- backends need to call io.AddKeyEvent(), io.AddMouseEvent() instead of writing to io.KeysDown[], io.MouseDown[] fields.
- backends need to call io.AddKeyAnalogEvent() for gamepad values instead of writing to io.NavInputs[] fields.
- for more reference:
- read 1.87 and 1.88 part of this section or read Changelog for 1.87 and 1.88.
- read https://github.com/ocornut/imgui/issues/4921
- if you have trouble updating a very old codebase using legacy backend-specific key codes: consider updating to 1.91.4 first, then #define IMGUI_DISABLE_OBSOLETE_KEYIO, then update to latest.
- 2024/10/18 (1.91.4) - renamed ImGuiCol_NavHighlight to ImGuiCol_NavCursor (for consistency with newly exposed and reworked features). Kept inline redirection enum (will obsolete).
- 2024/10/14 (1.91.4) - moved ImGuiConfigFlags_NavEnableSetMousePos to standalone io.ConfigNavMoveSetMousePos bool.
moved ImGuiConfigFlags_NavNoCaptureKeyboard to standalone io.ConfigNavCaptureKeyboard bool (note the inverted value!).
