[ase-users] Updating the gui window without opening a new window?

[Colin Bousige]

Hi Ask,

And thanks a lot for your answer.

What I want to do is a user-friendly tool with tkinter to build a specific structure with some parameters that the user enters. 
Then I want the resulting structure to be displayed, and update this display as the user changes the parameters – the slab was just an example.

So I guess a solution for this would be either:
- a way to trigger a gui update on demand or as it detects a change in the structure
- or display the gui as a frame within my tkinter app?
- or maybe just a way to close the gui window and then open a new one with view()
- or develop my app as an ASE plugin – which I would like avoiding doing...

And concerning edit(), it only results in crashing my python session, so I don’t know what I can do with it…
I use Anaconda python 3.6.2 on OSX and installed ASE with 'conda install -c conda-forge ase'.

Thanks a lot,
Colin
