Hello all,

I noticed today that, for example, my ‘QT GUI Time Sink’ blocks  
properties  
window is missing the config tab. This means I cannot change the label  
of  
my time sink plots. In general, all of my grc blocks have no tabs, only  
the  
main parameters window.

I’m using ubuntu 13.10 with gnuradio 3.7.3, installed using the  
master/unstable commands from the ettus research website.

Has anyone experienced something like this before? If so, what was the  
fix?

Thanks,  
Rich

Hi Rich,

The tab feature was introduced in 3.7.4, so if you need them, you’ll  
have  
to update. You can see all of the new features in that version here:

[http://gnuradio.org/redmine/projects/gnuradio/wiki/ChangeLogV3\_7\_4](http://gnuradio.org/redmine/projects/gnuradio/wiki/ChangeLogV3_7_4)

Note that you can middle-mouse click on the graph to get a menu that  
will  
allow you to change the labels and other features while the graph is  
running.
