Кароч, такая поебота, название слайдера уезжает в грецию, что делать?
вот код слайдера
C++:
ImGuiContext& g = *GImGui;

// Draw frame
window->DrawList->AddRectFilled(frame_bb.Min - ImVec2(0, 3) + ImVec2(0, 2), frame_bb.Max - ImVec2(0, 5) + ImVec2(0, 2), GetColorU32(ImGuiCol_Border), style.FrameRounding);
window->DrawList->AddRectFilled(frame_bb.Min + ImVec2(1, -2) + ImVec2(0, 2), frame_bb.Max - ImVec2(1, 6) + ImVec2(0, 2), GetColorU32(ImGuiCol_FrameBg), style.FrameRounding);
