Can't save topology and level 2 script in MiniEdit

[andredemori]

Expected/Desired Behavior:

save topology and save Level 2 script

Actual Behavior:

It is not saving the .mn and .py files. After saving the files are created with 0 bytes, that is, empty.

Detailed Steps to Reproduce the Behavior:

I'm just using a virtual machine that was downloaded from Mininet's own website. Link: https://github.com/mininet/mininet/releases/

Mininet 2.3.0
mininet-2.3.0-210211-ubuntu-20.04.1-legacy-server-amd64-ovf.zip
Latest release

Additional Information:

It's working fine, but apparently it can't save and consequently import saved .mn files. Do you have any recommendations for a release that is working better?

I used "Mininet 2.3.0" with VM files "mininet-2.3.0-210211-ubuntu-20.04.1-legacy-server-amd64-ovf.zip latest release". But when I run Miniedit and save the .mn files. The .mn file that I saved is empty when open. Any solution can I fix this problem?

this line needs to be changed in miniedit.py

mininet/examples/miniedit.py

Line 2019 in 6eb8973

for widget, item in self.widgetToItem:

instead of for widget, item in self.widgetToItem:
it should be for widget, item in self.widgetToItem.items():

because items() must be called on dict and it correct everwhere else other than this line.
