Hello,

I would like display a value over a custom background in gnu radio. In fact, the code should print the value somehow like a speedometer on semi-round. How can I achieve this? Is it possible to implement my idea into an Embedded Python Block which could take a value and then display it over the image? Or should I use the QT GUI Tab Widget (how can I add the picture, the value and display it OK)?

Thank you!

I do know if it is possible with Qt, If it is possible, it won’t be in the core librairy, but in an additional librairy. Or Maybe with KDE.
