Hi programmers, I need some advice on the application I am developing in python. It is an application that will be something like a network device that will include ping, traceroute, iperf, tshark, static IP address settings, DHCP, ARP table invocation, etc. and then implemented on RPi. Invoking these outputs is not so complicated, but the problem arises in developing UIs to be clear and simple for the user.
To give you a little insight into what my problem is.
If the user wants to ping an IP address, he / she will see a form in which he / she will write the IP address and after confirmation the output ping will show up on the right side of the application in real time. It all works fine.
However, the problem arises when I want to click on another function, such as traceroute, and do the same thing as the previous one. I will see 2 forms below each other and the output ping is still in place on the right.
I tried: I tried different conditions that could close the previous frames and listboxes so that the new selected form could be displayed. However, I did not succeed.
I want to achieve: As I mentioned, I am trying to close the previously used function and replace it with another function the user chooses.
Here is the source code:
Thank you
