[英]Qt - QProcess is not working
I try to launch internet explorer, So I use the below code 我尝试启动Internet Explorer,所以我使用下面的代码
QProcess * process=new QProcess(this);
QString temp="C:\\Program Files\\Internet\ Explorer\\iexplore.exe";
process->startDetached(temp.toStdString().c_str());
But it doesn't work. 但它不起作用。
Try: 尝试:
QProcess * process=new QProcess(this);
QString temp="\"C:\\Program Files\\Internet Explorer\\iexplore.exe\"";
process->startDetached(temp);
You need to use escaped quotes since the path has a space in it, or possibly escape all the spaces (you missed Program\\ Files
in the code you posted). 您需要使用转义引号,因为路径中有空格,或者可能转义所有空格(您在所发布的代码中错过了
Program\\ Files
)。
How about that? 那个怎么样?
QDir dir("C:\\");
QProcess::execute("explorer.exe", QStringList() << dir.toNativeSeparators(dir.path()));
