SetItemUsingMouseWheel Obsoleted?

[michaelquigley]

Version: v1.89.1

What happened to SetItemUsingMouseWheel? What's the current mechanism to achieve this in 1.89.1?

    // Obsolete functions
#ifndef IMGUI_DISABLE_OBSOLETE_FUNCTIONS
    inline void     SetItemUsingMouseWheel()                                            { SetItemKeyOwner(ImGuiKey_MouseWheelY); }      // Changed in 1.89

According to the above, it looks like I can maintain the functionality using:

ImGui::SetItemKeyOwner(ImGuiKey_MouseWheelY);

Will ImGui maintain this capability going forward? It looks like the SetItemKeyOwner stuff is "experimental"?

See #2891 (comment) for some info on this deprecated function and a suggestion to use SetItemKeyOwner as part of the more generic system that replaces it.

Also linking to #4207, cross-posting
Everything in imgui_internal.h is technically not guaranteed to be stable, but SetItemKeyOwner() is the way forward.
As SetItemUsingMouseWheel() was mentioned in #5108 #4303 #4207 #2891 #2704 I added a redirection function in imgui_internal.h but those are fairly exceptional and the SetItemUsingMouseWheel() inline function will eventually be removed.

There is a very small change that SetItemKeyOwner() will evolve but either way the feature will be preserved.
