Thanks to you.

With gtk+3-3.18.9, if I resize the window, the PANE_BOX (with the buttons
[ ]unite [ ]sync etc) is over the SND_PANE.

The child is added with gtk_paned_add1() and it is equivalent to

    gtk_paned_pack1(paned, child, false, true)

If we set the argument "shrink" to "false", that problem seems fixed:
