[NetworkManager-libreswan/lr/gtk-4.0: 8/10] editor: split setup of advanced dialog widgets off




commit c9e594cf0f57434b11e1c653f070b9416757c74e
Author: Lubomir Rintel <lkundrak v3 sk>

    editor: split setup of advanced dialog widgets off
    
    Currently the advanced dialog always remembers what's set, regardless of
    whether the user confirms it or dismisses it. This is not what users
    expect and we'll fix it in the following commit.
    
    Splitting off the widget setup and readback of values is done in
    preparation for that.
