Phyton Software Add Button and Autocomplete

Hi, I've a python software (I have the source too, of course), this software is a GUI that installs some script using the shell on some server. What I need: 1. I need to add 1 buttons to run: One line of code on the shell for button 1 (we need to grab some details from the GUI - root/password) - button will be blur(no active) until adding those details on the GUI. - It is only 1 linux command to run, nothign else! 2. Remove an autocomplte field (partially), this field autocompletes when filling other field, I want to only have the autocomplete active when I chose option 1 and not when choosing option 2 ...right now autocomplet works for option 1 and 2. 3. There is a little bug when filling all the field it is stil lasking to fill a missing field, that is not true! then I have to go and replace someting on that field and the nI can continue , that is not good, it should work without having to do that... it is just a form and I'm getting an alert saying the fields ar enot all filled in, when they are! 4. The software crashes sometimes, I need you to take a look at it. Finally, you will compile it and send it to me for testing, after all is ok, I'll release the milestones and get the new source. That's it, Thanks
