关于QProcess的start函数

[shn521]

start函数的路径不能有空格，如果路径是有空格的该怎么处理？

[jody_go]

用/s转义。Qt帮助文档中关于 QProcess的start函数有例子的

[写不动代码的人]

QProcess process; process.start("del /s *.txt"); // same as process.start("del", QStringList() << "/s" << "*.txt");

请问例如路径为：C:\124 45\56 78\bb.exe。该怎么写？

空格不用管在要执行的路径前和后加上双引号就可以。 比如process.start("D:\Program Files\XiaZaiBa.exe"); 写成process.start("\"D:\Program Files\XiaZaiBa.exe\"");就可以了。

window和Linux处理是不同的转义 qt助手上是如下写的 The program string can also contain quotes, to ensure that arguments containing spaces are correctly supplied to the new process. For example: QProcess process; process.start("dir \"My Documents\""); If the QProcess object is already running a process, a warning may be printed at the console, and the existing process will continue running. Note that, on Windows, quotes need to be both escaped and quoted. For example, the above code would be specified in the following way to ensure that "My Documents" is used as the argument to the dir executable: QProcess process; process.start("dir \"\"\"My Documents\"\"\"");

process.start("C:\\124 45\\56 78\\bb.exe"); 或者 process.start("C:\\124 \s 45 \s \\56 \s 78\\bb.exe");
