[Qt-interest] efficient ways to store menu items in file with/without QSettings

[_h_]

Hi,
my Qt application requires to store the menu information (submenus,
menuitems, shortcut keys, etc), to persist across sessions.

1) Can you please suggest efficient ways to store this in file other than
QSettings?

2) how efficient QSetting is, in storing hierarchical data (without
repeating the same info) ?
     Just for illustration, how efficiently the QTreeWidgetItems can be
stored using QSetting, without repeating the info like...
    <example 'setting.txt' file>
    Line1: main_menu/File
    Line2: main_menu/File/Print
    ...
    Line 10: main_menu/Edit
    Line 11: main_menu/Edit/Copy
    ...
    Here you can see that the 'main_menu', 'File' and 'Edit' is redundant
info, using QSettings how it can be avoided ?

Thank you.
