Missing expansion arrows in gtk+3 tree view

Missing expansion arrows in gtk+3 tree view

I have written a personal finance manager (which I call Newcash and which I 
will be releasing on github as soon as I finish the documentation). It is 
gtk+3-based and makes use of gtk's treeview to display the tree of 
accounts. This display normally has little arrows to the left of expandable 
accounts (those accounts in the tree with children). It works correctly on 
Arch Linux, Linux Mint, OpenBSD, FreeBSD and I may have forgotten something 
on which I've tested it. The arrows are missing when I run the application 
on a newly installed Void system. Clicking in the area of the missing 
arrows does expand the account, so that functionality works, but the lack 
of the display of those little icons is unacceptable. I suspect it's due to 
the font chosen by default, but that's pure speculation on my part. And 
anticipating a question, yes, I did completely rebuild my application 
having installed Void's gtk+3 and gtk+3-devel packages.

I really like some of the ideas behind void (particularly the non-use of 
systemd), but it feels like it's not quite ready for prime time. I realize 
that putting a Linux distribution together is a huge amount of work 
involving a gazillion details and so I'm not surprised that Void feels as 
if it's not quite there yet, given its relative youth.

You could try gtk3-widget-factory from the gtk+3-demo package.
On Page 3 there is a TreeView (is it the same?) that is working for me, 
they change if i switch the gtk theme.
Which gtk theme do you use currently?

No, not the same. See attached screenshot of the top-level window of my 
application, showing the top of the accounts tree. This screenshot was done 
on an Arch Linux system, so the little expansion arrows are visible, as 
they should be. On the Void system, they are not visible, but clicking the 
blank space where you would expect them to be does expand accounts with 
children. The problem is that you can't distinguish those with children 
from those without (leaves). This is a show-stopper for me.

I use whatever the default is. According to the Arch Wiki, Adwaita is the 
default for Gtk+3, though it's not clear from their language whether that's 
specific to Arch or a default set by Gtk. In any case, I tried forcing the 
Adwaita theme on Void and it made no difference.

Thanks for trying to help.

Donald, did you find a solution for the problem? I'm struggling with the 
same behaviour (only difference is that I use Rust bindings for gtk3).
