QFile doesn’t create the file - qt

Question

I am writing a simple program. The program has 2 QStrings set with following variables: path and name of file, there is a 3rd QString which I later on use to put the result of the append of the first 2 QString together in. What I want to do is append the 2 QStrings and put them in the appendAll QString, and then send the appendAll QString to the QFile variable constructor. Now when I do that, it prints "Failed to Create File", this is the code I used:
#include <QString>
#include <QTextStream>
#include <QFile>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QTextStream output(stdout);
QString location = "/home/mahmoud/Destkop";
QString name = "mahmoud.txt";
QString appendAll;
if( !location.endsWith("/") )
{
location.append("/");
}
appendAll = location.append(name);
output << appendAll << endl;
QFile myFile(appendAll);
if(myFile.open(QIODevice::WriteOnly | QIODevice::Text ))
{
output << "File Has Been Created" << endl;
}
else
{
output << "Failed to Create File" << endl;
}
QTextStream writeToFile(&myFile);
writeToFile << "Hello World" << endl;
myFile.close();
return a.exec();
}
But when I type the string directly into the QFile variable constructor in the same program it prints, "File Has Been Created" and I find it on my desktop, the below code works fine:
QFile myFile("/home/mahmoud/Desktop/mahmoud.txt");
if(myFile.open(QIODevice::WriteOnly | QIODevice::Text ))
{
output << "File Has Been Created" << endl;
}
else
{
output << "Failed to Create File" << endl;
}
I want to be able to already have QStrings and append them and send them to the QFile variable constructor, any suggestions on how to solve my problem? Thank You

Answer 1

Do not hard-code this filesystem location. Instead, in Qt4 you should be using QDesktopServices:
QString location =
QDesktopServices::storageLocation(QDesktopServices::DesktopLocation);
In Qt5, it's QStandardPaths:
QString location =
QStandardPaths::writableLocation(QStandardPaths::DesktopLocation);
This is important because /home/username/Desktop is not guaranteed to be the user's Desktop folder.

Answer 2

There is typing error in your code: Destkop should be Desktop. Qt can't create file in non-existent directory.
