Qt: Get ASCII Code From QChar

I need to get the ASCII code from a QChar.

In Qt 5.2 QChar::ToAscii has been removed.

Here is my code. How can I get the ASCII code?

QString data;
int key;
key = data.at(i);
Solution

  • Use:

    char QChar::toLatin1() const

    From the doc:

    Returns the Latin-1 character equivalent to the QChar, or 0. This is mainly useful for non-internationalized software.

    From a Qt5.0 version

    char QChar::toAscii() const

    This function is deprecated. Returns the Latin-1 character value of the QChar, or 0 if the character is not representable.

    Example

    QString test("test");
QChar c = test.at(0);
int v_latin = c.toLatin1();
int v_ascii = c.toAscii();
qDebug() << v_latin << " " << v_ascii;

    Output:

    116   116
