## 單詞補全
對 QLineEdit 進行自動補全
```
QStringList wordList;
wordList << "alpha" << "omega" << "omicron" << "zeta";
//進行排序
wordList.sort(Qt::CaseInsensitive);



QCompleter *completer = new QCompleter(wordList, this);
completer->setCaseSensitivity(Qt::CaseInsensitive);


// ① QCompleter::PopupCompletion，是指正常的彈出單詞列表顯示。
// ② QCompleter::InlineCompletion，不彈出列表，將最接近的一個單詞顯示到編輯框里，補全的后半截字符用選中的高亮顯示。
// ③ QCompleter::UnfilteredPopupCompletion，如名字一樣，把單詞補全器里所有可能的單詞都列出來，不做匹配篩選。

completer->setCompletionMode(QCompleter::PopupCompletion);
ui->lineEdit_2->setCompleter(completer);
```
