One app should help to manage links between book pages, basically it has to handle a small database in which I can add books (title, ID) and linked pages (couples of numbers). The database must be obviously persistent. The other app should

问题 I'm having trouble implementing a QListWidget with custom items that can be reordered by dragging and dropping. The problem is when I make a fast double click (a very short drag&drop) on an item, the item sometimes disappears from the QListWidget. This is the constructor for my Widget: ListPopisiDragDrop::ListPopisiDragDrop(QWidget *parent) : QListWidget(parent) { setSelectionMode(QAbstractItemView::SingleSelection); setDragEnabled(true); viewport()->setAcceptDrops(true); setDefaultDropAction

问题 My application consists of one QMainWindow, and a nested QStackWidget containing the rest of the application "forms". I would like to have a soft-key activated menu on each of those sub forms. How is this possible? 回答1: Hi sabbour here is the link,which gives you a detailed info, perhaps this could be very useful 回答2: You need to create the Multiple widgets and associated menu items, when you load the widget in stack, you need to load your menu items accordingly in the mainwindow menu bar.
