推荐答案

写一个文件已经完全不相关到任何对话框，一般与UI无关。如果你有一个与.NET相关的印象，这只是因为你对.NET没有任何线索，无论你创建了多少代码。



理想情况下，编写文件不应与QT相关。然而，由于某些原因（我不认为这是讨论它们的地方），文件支持包含在QT中。请参阅：

http://doc.qt.digia.com/qt/qfile .html [ ^ ]，

http://doc.qt.digia.com/qt/qiodevice.html [ ^ ]，

http://doc.qt.digia.com/qt/qbuffer.html [< a href =http://doc.qt.digia.com/qt/qbuffer.html\"target =_ blanktitle =New Window> ^ ]。



使用C ++，您可以通过< cstdio> 或< iostream> ，但另请参阅上面QT参考页面参考中的评论，第一个。

Writing a file is already totally unrelated to any dialog, and unrelated to UI in general. If you had the impression that is it related in .NET, this is only because you have no clue about .NET as well, no matter how much of code you created.

Ideally, writing files should not be related to QT. Nevertheless, by some reasons (I don''t think this is a place to discuss them), file support is included in QT. Please see:
http://doc.qt.digia.com/qt/qfile.html[^],
http://doc.qt.digia.com/qt/qiodevice.html[^],
http://doc.qt.digia.com/qt/qbuffer.html[^].

With C++, you can directly use C++ API via <cstdio> or <iostream>, but see also the comments in the QT reference page reference above, the first one.
