请问QT中如何实现文件复制呢？？？

用QFile::copy

附Qt Assistant说明

bool QFile::copy ( const QString &fileName, const QString &newName ) [static]

This is an overloaded member function, provided for convenience.

Copies the file fileName to newName. Returns true if successfulotherwise returns false.

If a file with the name newName already exists, copy() returns false (i.e., QFile will not overwrite it).

See also rename().

#include <QFile>

QFile::copy(const QString &fileName, const QString &newName)

//using static funtion
