@tvcastillod and @JoaoDell, Can you look at this PR ? Thank you

[tvcastillod]

Hi @ganimtron-10, overall it looks like this new FileDialog component is working fine so far.

I just want to understand better which issues you addressed and how did you fix them, for example, for the ZeroDivisionError I saw you fixed it by adding a condition over denom variable, In which cases did this error occur before? or with the Overflow issue, what does it refer to? is it about the file names display?

Also, the example looks good, it's simple and easy to understand.

Hey @ganimtron-10, I have just finished reviewing your PR. All the tests passed and the example shows well the feature you worked on. About the scripts, everything seems fine and well organized. Overall looks fine and ready to merge, so good job! I guess I just wanted to better understand the same details @tvcastillod pointed out in her review, as I checked the current folder's path indeed expands out of the textbox. Is it described somewhere in your blogposts?
