Unexpected Keyboard Focus Between Adjacent Vertical Boxes

[Revisto (Alireza Shabani)]

Hi! I have a question about keyboard navigation between boxes.

This is a minimal example of my issue. I have two vertical boxes with buttons, placed side by side in a horizontal box. When I use the arrow keys to navigate, for example, moving right from Button 1A skips to Button 3B instead of Button 1B.

Is this expected? Is there a workaround?

Here’s a minimal Blueprint version of the issue:

using Gtk 4.0;
using Adw 1;

Box {
  orientation: horizontal;
  spacing: 20;

  Box {
    orientation: vertical;
    spacing: 10;

    Gtk.Button {
      label: "Button 1A";
    }

    Gtk.Button {
      label: "Button 2A";
    }

    Gtk.Button {
      label: "Button 3A";
    }
  }

  Box {
    orientation: vertical;
    spacing: 10;

    Gtk.Button {
      label: "Button 1B";
    }

    Gtk.Button {
      label: "Button 2B";
    }

    Gtk.Button {
      label: "Button 3B";
    }
  }
}

Hi,

That’s looks like a bug, yes.
In gtk3, the left/right arrows used to focus the widget on the same “visual row”, but it looks like it’s not the case anymore in gtk4.
