// [EXPERIMENTAL] Low-Level: Key/Input Ownership
|
||
|
|
// - 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.
