Is there a resize to content mode for an axis using ImGui::BeginChild()?

I want to have horizontal scrolling but I don't want there to be vertical scrolling. I want it to resize to the size of the contents vertically. Is there anything like this?

I can manually set a fixed size, but then I need to calculate and compensate for when the horizontal scrollbar might be visible.

In the meanwhile, maybe using both flags ImGuiWindowFlags_HorizontalScrollbar | ImGuiWindowFlags_AlwaysHorizontalScrollbar can allow you to compute that extra height for the scrollbar since it won't change any more.

Hello @skl131313, unfortunately it isn't possible at the moment. I see what you are trying to do and agree it would be helpful. I have an idea of how to implement it but it's not a trivial change and I don't know when I'll be able to tackle it.

No worries if it requires a big change, it's more of a nice to have feature than a requirement.
