Customize treeview expander for HiDpi [message #1745161]

Hi,

I hope this issue is not OT in this forum - please advise me the correct one, if I'm wrong ...

I'd like to change the size of the treeview expander (i.e. the dropdown in front of tree entries) in Eclipse Neon, as it's tiny on a QHD display.

I could get it to work by disabling GTK3 [1] and using a custom .gtkrc-2.0 [2],
but what needs to be configured for GTK3 [3]?

I've tried it with choosing the "default" theme in eclipse and a ~/.themes/default/gtk-3.0/gtk.css [4] only containing the following entry ... but no avail:

GtkTreeView {
        expander-size: 20
}

Best wishes,
Andi

I've solved it by adding the following to ~/.config/gtk-3.0/gtk.css

* {
-GtkTreeView-expander-size: 20;
}

It seems, gtk.css will be parse when it's accompanied by a settings.ini ... but I might be wrong. If unsure, you can use strace [1] to check which files are tried to be opened.
So it seems the styling [2] needs that dash-notation [3].

For further styling the inspector [4] is handy.
