Display hexdecima format

taku-s

Hi all.

I want to display the string entered in lineEdit_1 in hexadecimal format in LineEdit_2.
For example, if I enter 12AB, yI want to display 31 32 41 42.

What should I do?

Thank you.

Hi @taku-s,

just to add an example to @ChrisW67's good hints:

lineEdit_2->setText(lineEdit1->text().toLocal8Bit().toHex(' '));

Note: if your text only contains ASCII characters, you can replace toLocal8Bit() with toLatin1(). If not, you should also check if toUtf8() might be the better solution, but keep in mind that one character in lineEdit_1 might result in several characters in lineEdit_2 then.

QString::toLocal8Bit() (or one of its sibling functions) and QByteArray::toHex()
