[Discuss-gnuradio] Print variable run-time selected from QT GUI Range

Hi,

 

I have the following flow-graph:

Vector source à Throttle à Multiply constant à QT GUI Sink

 

I also have a QT GUI Range which is used to select the variables in Multiply constant block.

 

Now I want to print the constant value from the Multiply constant block as it changes and print into the console.

 

What is the best way to do so? Do I edit the code of the block and just print the variable ? Or any other simpler way?
