// - The idea is that instead of "eating" a given input, we can link to an owner id.
// - Ownership is most often claimed as a result of reacting to a press/down event (but occasionally may be claimed ahead).
// - Input queries can then read input by specifying ImGuiKeyOwner_Any (== 0), ImGuiKeyOwner_None (== -1) or a custom ID.
// - Legacy input queries (without specifying an owner or _Any or _None) are equivalent to using ImGuiKeyOwner_Any (== 0).
// - Input ownership is automatically released on the frame after a key is released. Therefore:
// - for ownership registration happening as a result of a down/press event, the SetKeyOwner() call may be done once (common case).
// - for ownership registration happening ahead of a down/press event, the SetKeyOwner() call needs to be made every frame (happens if e.g. claiming ownership on hover).
// - SetItemKeyOwner() is a shortcut for common simple case. A custom widget will probably want to call SetKeyOwner() multiple times directly based on its interaction state.
// - This is marked experimental because not all widgets are fully honoring the Set/Test idioms. We will need to move forward step by step.
// Please open a GitHub Issue to submit your usage scenario or if there's a use case you need solved.

// [EXPERIMENTAL] High-Level: Input Access functions w/ support for Key/Input Ownership
// - Important: legacy IsKeyPressed(ImGuiKey, bool repeat=true) _DEFAULTS_ to repeat, new IsKeyPressed() requires _EXPLICIT_ ImGuiInputFlags_Repeat flag.
// - Expected to be later promoted to public API, the prototypes are designed to replace existing ones (since owner_id can default to Any == 0)
// - Specifying a value for 'ImGuiID owner' will test that EITHER the key is NOT owned (UNLESS locked), EITHER the key is owned by 'owner'.
// Legacy functions use ImGuiKeyOwner_Any meaning that they typically ignore ownership, unless a call to SetKeyOwner() explicitly used ImGuiInputFlags_LockThisFrame or ImGuiInputFlags_LockUntilRelease.
// - Binding generators may want to ignore those for now, or suffix them with Ex() until we decide if this gets moved into public API.
IMGUI_APIboolIsKeyPressed(ImGuiKeykey,ImGuiIDowner_id,ImGuiInputFlagsflags=0);// Important: when transitioning from old to new IsKeyPressed(): old API has "bool repeat = true", so would default to repeat. New API requiress explicit ImGuiInputFlags_Repeat.

// - When using one of the routing flags (e.g. ImGuiInputFlags_RouteFocused): routes requested ahead of time given a chord (key + modifiers) and a routing policy.
// - Routes are resolved during NewFrame(): if keyboard modifiers are matching current ones: SetKeyOwner() is called + route is granted for the frame.
// - Route is granted to a single owner. When multiple requests are made we have policies to select the winning route.
// - Multiple read sites may use the same owner id and will all get the granted route.
// - For routing: when owner_id is 0 we use the current Focus Scope ID as a default owner in order to identify our location.

// Template functions are instantiated in imgui_widgets.cpp for a finite number of types.
// To use them externally (for custom widget) you may need an "extern template" statement in your code in order to link to existing instances and silence Clang warnings (see #2036).
