Hi.

I'm trying to set the window position and size of a popup modal window.
I've tried with:

    if (ImGui::BeginPopupModal(...)) {
        ImGui::SetWindowPos(wndPos);
        ImGui::SetWindowSize(wndSize);
        ...
        ImGui::EndPopup();
    }

but it doesn't seem to work...

Actually it seems that the window is always centered... am I missing some flag ?

Always use SetNextWindowPos,
  SetNextWindowSize()
  SetWindowPos/SetWindowSize may be removed.

Does it actually fix your issue?

Yes! Although I had also one frame delay before SetNextWindowPos was actually applied.
Not sure if that is something dealing with my specific (very complex) code...

Basically I had to call SetNextWindowPos(...) at the frame after the one in which I called for the first time ImGui::OpenPopup() and ImGui::BeginPopupModal().

However this frame-lag issue was very easy to handle for me.
