How to get the name of parameters ？

[sonichy]

I need to print the name of parameters.

QStringList player1;
player1 << "a" << "a" << "b" << "c";
duplicateCount(player1);
void MainWindow::duplicateCount(QStringList stringList)
{
    qDebug() << stringList.name << stringList;
}

Output:
player1 ("a" , "a" , "b" , "c")

Do you want fetch a, b, c etc separately ? What do u mean by get the name of parameters ?Did you check on stringList.at(index) function ?

In that case, you can use a macro. like this:

#define PRINT_VAR_NAME(name) printVarName(#name, (name))
void printVarName(const QString &name, const QStringList &list)
{
    qDebug() << name << list;
}
[...]
QStringList player1;
player1 << "a" << "a" << "b" << "c";
PRINT_VAR_NAME(player1);

void MainWindow::duplicateCount(QStringList stringList)
{
    qDebug() << Q_FUNC_INFO << stringList;
}

Q_FUNC_INFO just print:

void MainWindow::duplicateCount(QStringList)

But I want to print var name: player1.

You cannot do that in C++, because variable names are removed when your code is compiled.

You can pass the name as a separate parameter:

void MainWindow::duplicateCount(const QStringList &stringList, const QString &name)
{
    qDebug() << name << stringList;
}

Anyway, why do you need to know the name?

@JKSH It seems like SLOT needs sender().
