Hi I m trying to make a wireshark statistics menu like that of the 'WLAN Traffic' under the statistics menu. My code has been compiling but I am unable to see the menu appear once complied. I am running it on Ubuntu. This is the code, the main packet tapping code is not important right now. All I want right now is the button appearing on the statistics menu.
