    What do you mean by "later" ? You want the data to be available next time you start the app, or few minutes "later" during program execution ?

    You can store them in QList, ans use them later, if you want to use next time the application starts then save into QList, and then save QList to a file or database... or even QSettings can be used

    Hi, I use this to refresh file and directory list in my "browse folder" application. I store items opened or selected in a map but there is a problem when I collapse item. The "on_treeWidgetName_itemCollapsed()" private slot of my c++ class are not called (=> closed item is not removed from map).
    Have you any suggestion to solve this?
