I have been using gnurad-companion for some time now but for the last few months I have been getting errors that prevent use. My system is an up to date Mint OS. The version of the application is 3.7.6.1. I am experiencing errors that according to internet searches appear every now and then for several years. What is inhibiting me is when the top\_block is executed, it dies with “no attribute"GetWIn”. Unfortunately, all remedies I have tried have not helped. Any suggestions, pointers or other help would be appreciated. 73, Alan - W6ARH ---

Hi Alan, my first guess here would be that you’re using WX blocks and your “options” block is set to QT or console only (or maybe QT usage with WX option). If that is not it, can you paste the full output? Greetings, Marcus ---

Marcus, Thanks for the assistance. I changed the display for qt-gui to wx-gui and it now runs correctly. My only remaining concern is why doesn’t it work with qt-gui. I have QT4 installed. 73, Alan - W6ARH From: discuss-gnuradio-bounces+alan.r.hill=removed\_email\_address@domain.invalid [[mailto:discuss-gnuradio-bounces+alan.r.hill=removed\_email\_address@domain.invalid](mailto:discuss-gnuradio-bounces+alan.r.hill=removed_email_address@domain.invalid)] On Behalf Of Marcus M.

Because your blocks are WX-GUI. Changing the parameter only changes the “boilerplate” code that is emitted. So, if you’re using QT-GUI boilerplate with WX-GUI blocks, that won’t work.

If your options block is set to “qt-gui” you can use qt-gui and only qt-gui blocks in your flowgraph. Likewise, if your options block is set to “wx-gui” you can use wx-gui and only wx-gui blocks in your flowgraph. Since wx-gui blocks are working for you, I can conclude your options block is set to wx-gui. Are you aware of the options block field we are referencing? I’m thinking you might not be. The options block is one of two default blocks that are included in a flowgraph when you first create a new blank one. Check it out. v/r, Rich
