Qdebug display hex value

Question

I am trying to display a number using QDebug in the Hex format. Below is the code which I have written. It is working but the output has string contents enclosed in double quot

Answer 1

Use noquote() to avoid the quotation marks. As in:

qDebug().noquote() << QString::number(value, 16);

Answer 2

May be a little late, but in case someone needs this:

As statet in the answere by Kuber Ober, Qt only removes the quotes if it's a const char * passed to qDebug. However, Qt provides a macro to do the same with a QString - The qPrintable macro:

qDebug() << qPrintable(QString("String without quotes")) << QString("String with quotes");

This way, you can use the QString::number function (as provided by TheDancinZerg) to format the string:

int value = 0xFFFF;
qDebug() << qPrintable(QString::number(value, 16));

Answer 3

int value = 0xff005542;
qDebug() << QString("%1").arg(value , 0, 16).toUpper();

>>> FF005542

That'll give you hex output at whatever length is required. But if you'd like fixed width output, this is handy (example of four hex digits):

int value = 0xff;
qDebug() << QString("%1").arg(value, 4, 16, (QChar)'0').toUpper();
//      Here's the fixed field length⬆︎

>>> 00FF
