cpp/Qt : per class debugging

Question

I'm developing a Qt application. For each class, I'm trying to mimic the framework, such as error() and errorString() method, use of Private implementation.

But I would like to add a per class debugging:

• Set a macro to the desired level of debug,
• have a macro or a function that knows the level of debug, and use qDebug() or qWarning() which is class independant, and will know the current class's name (for some pretty prints)

Anyone have a good idea to implement this ?

Answer 1

Hi.

You may write a class, for example CDebug with all needed debug methods, and use it in other classes, like:

class CMyDialog : public QDialog, public CDebug {...};

Answer 2

Maybe the QxtLogger class, part of the Qxt library (an extension library for Qt) provides what you need.

I would definitely consider using something already existing and tested rather than implementing my own logging solution.
