Getting ginput to read axes on an appdesigner GUI

7 views (last 30 days)
I am trying to use ginput() on a GUI that I am building with appdesigner. The problem is that when I call ginput(), it creates a new figure window and then acts on that window, instead of on my GUI.
I've tried preceding it with a call to axes, i.e.
axes(app.ImageAxes);
[x, y] = ginput(1);
But that has the same effect, it still creates a new figure window and then puts the cross hairs on the new window.
What is the proper way to get ginput() to read from the axes in my GUI?
I just upgraded today so I am running in R2022a.

Thank you. I just want to summarize that what appears to be the best answer (I haven't tried it yet) is the one titled "ginput is now supported in AppDesigner starting in r2020b". This was in fact the reason I upgraded from R2020a, after reading on the mathworks site that ginput was supported in later versions. So I was a little frustrated when after the update, it still didn't seem to work.
According to that answer, the key apparently is to set handle visibility. So I'm going to experiment with that.
Update: Yes, that solution worked. Also new to me was using
set(0, 'CurrentFigure', fig);
to set the focus to the desired figure.
