**Version/Branch of Dear ImGui: Docking Branch

**Back-end/Renderer/Compiler/OS OpenGL

Back-ends: imgui_impl_opengl3.cpp + imgui_impl_glfw.cpp

I've been trying to disable the close window buttons and hide tab bar buttons for my windows which are in the dockspace but the close tab button still shows after doing this.
ImGui::Begin("Property", nullptr)

I'd like if someone guided me as to how to disable the hide tab bar buttons as well.

Tried this
ImGui::Begin("Property", nullptr, ImGuiWindowFlags_NoTitleBar);
But even the titlebar still shows.
