QLabel *lbl = new QLabel("Select");
QLineEdit *lineEdit = new QLineEdit();
lbl->setBuddy(lineEdit);
QCompleter *completer = new QCompleter(wordList);
completer->setCaseSensitivity(Qt::CaseInsensitive);//大小写匹配
//completer->setCompletionMode(QCompleter::InlineCompletion);//完整的匹配Inline （1）
completer->setCompletionMode(QCompleter::PopupCompletion); //匹配以弹出式显示（2）
//completer->setCompletionMode(QCompleter::UnfilteredPopupCompletion);//将全部信息以弹出式显示
//completer->setCompletionRole(0); //设置ItemDataRole
lineEdit->setCompleter(completer);
lay->addWidget(lbl);
lay->addWidget(lineEdit);
win->setLayout(lay);
win->show();
return a.exec();
