After almost 4 months of work on Google Summer of Code 2017, finally I'm completing my proposal. Every widget migration and every commit/PR/issue/discussion with my mentors about Cricket , Toga and rubicon-objc were detailed on the Issue 58.

"Eating your own dog food"

The best way to show that a product is reliable to the customers is use it. So, the way to show that Toga is an effective tool to build a GUI is to build a complete application using it.

Cricket is a graphical tool that helps you run your test suites. Its current version is implemented using Tkinter as the main GUI framework. So, why not test Toga inside of another product from BeeWare? That's what I have acomplished during my GSoC work.

Results

The proposal focus not only on the port of Tkinter to Toga, but on mapping the necessary widgets for a real application using Toga framework. To help me to map this I studied more about Tkinter, Toga, Colosseum, rubicon-objc, Objective-C, Cocoa and CSS.

The work I did during GSoC were sent throught the PR 65, reported on the Issue 58 and the final demonstration of the work can be seen in this link. There were widgets used on Cricket that weren't ready yet on Toga, so some improvements were necessary on Toga so that I could use them on Cricket. In summary here are some PRs and issues that I contributed to get my work done in Cricket:

  • Issue 205 : adding MultiviewTextInput results in TypeError

Closed issue that I reported to Cricket:

  • Issue 59 : Run selected doesn't count/ runs every test selected in a test module, was fixed by me

Open issue that I reported to rubicon-objc Jonas Obrist repository:

  • Issue 1 : Seg Fault when iterate through a NSIndexSet using block notation

Future Plans

There are some features on Cricket that I want to help develop in a near future, for example:

  • A button to refresh all the tests tree
  • Cricket settings

Also, there are some issues remained after this migration to Toga. These issues will be fixed on Toga widgets in a near future too, for example:

  • A gap between the output and error boxes when there is no output message
  • Run a test if the user click on it

I truly believe that Toga will be the oficial framework on Python to build GUI for multiplatforms applications, so I'll continue to contribute to this project because I want to use in every application that I would need a GUI.

Final Considerations

I would like to truly thank my mentors Russell Keith-Magee and Elias Dorneles for guide and help me so much during this period. The opportunity to be part of this community was a great honor to me, thank you so much to accept me in this program Russell Keith-Magee. Also, I want to thank Philip James that made some reviews in my PRs and Jonas Schell that fixed one issue that I sent to Toga.
