Re: [Discuss-gnuradio] displaying a hexidecimal value with QT GUI Label

[Marcus Müller]

That "formatter" needs to be a python callable that takes a single numeric argument. In your case something like:

hex

(hex is a python built-in callable that converts numbers to hex strings), or, giving you more flexibility:

"0x{:X}".format

(because "{:x}".format(15) returns "F", See [1]). That format allows you to do much more (fixed width, 0-filling etc).

If things get more complicated, you might just need to use a python lambda.

Best regards,

Hello All,

I would like to display an integer variable with the QT GUI label as a hex value. Is there a way to do that with the Formatter option? I cannot figure out the syntax of the formatter.

Thanks,

Ryan Marlow
