Aligning gb4e examples with tikz-qtree

Question

I would like to fit multiple tree structures onto one and the same page (preferably next to each other), while also numbering them with gb4e so I can refer to them later on. Although this seems to work, I have a problem with the alignment of the gb4e numbers; for some reason they do not align properly.

I have included working code below, together with an example.

I have tried working with multicols, inserting different kinds of skips, hline, hfill, text with phantom, but nothing seems to work properly.

Any recommendation whatsoever would be really helpful!

\usepackage[utf8]{inputenc}
\usepackage{tikz-qtree,tikz-qtree-compat}
\usepackage{gb4e}

Answer 1

Okay, so I solved it by using multicols together with something I found over here on centering trees with the help \hfil and on using [baseline] to keep the example numbers above the trees. This made my trees go into the margins, so I provided a \newline after each \ex and that seemed to solve that issue. I'm sure, however, that this is very rough-and-ready and that there are probably way better ways to solve this, so feel free to comment!

Updated code:

\begin{exe}
    \begin{multicols}{3}
        \ex SVO
        \newline
        \hfil
        \resizebox{\linewidth}{!}{
            \begin{tikzpicture}[baseline]
            \Tree
            [.AgrSP \node(subj){Subj}; 
                [.AgrS\1 
                    [.AgrSº \node{AgrSº};\node(verb){Vº}; ]
                    [.VP \node(subjtrace){$<$Subj$>$};
                        [.V\1 \node(verbtrace){$<$Vº$>$}; ]                         
                    ]
                ]
            ]
            \end{tikzpicture}\hfil}
        \columnbreak
        \ex VSO
        \newline
        \hfil
        \resizebox{\linewidth}{!}{
