QwtText warning: Type conversion already registered from type QString to type QwtText

[Uwe]

I'm using qwt-6.2-git and am getting a warning "Type conversion already registered from type QString to type QwtText" in the terminal when doing the following:

QString myString("hello");
QwtText myText(myString);

QString myString("hello");
QwtText myText(myString);

To copy to clipboard, switch view to plain text mode 

I can't find anything in my code that's registering a QString to QwtText.

Is there a way I can turn off this warning or understand what's causing it?

The converter is registered here: https://sourceforge.net/p/qwt/git/ci...c/qwt_text.cpp
Maybe you can use the debugger to find out why it is called twice or if there is another place where such a converter is registered.
