Instance 1 File : examples/common/imgui/imgui_widgets.cpp Enclosing Function : SplitterBehavior@ImGui Function : ButtonBehavior@ImGui https://github.com/lighttransport/nanort/blob/135a452385a2903592db7518fbb80479d99ab9c3/examples/common/imgui/imgui_widgets.cpp#L1199 Issue in: held, hovered

Code extract:

    bool hovered, held;
    ImRect bb_interact = bb;
    bb_interact.Expand(axis == ImGuiAxis_Y ? ImVec2(0.0f, hover_extend) : ImVec2(hover_extend, 0.0f));
    ButtonBehavior(bb_interact, id, &hovered, &held, ImGuiButtonFlags_FlattenChildren | ImGuiButtonFlags_AllowItemOverlap); <------ HERE
    if (g.ActiveId != id)
        SetItemAllowOverlap();
