Recently I have been using Visul Basic for Apllication (VBA) and I made a userForm with it. Even if i didn’t enjoyed too much VBA I fallen completely in love with the ease of use of some tools inside it, you can make something like this with just a few clicks
Processing already has several GUI libraries, the most commonly used (based on number of questions I see in the forum) are controlP5 and G4P, both are long established and well supported libraries. G4P was first released on 22nd March 2009 so will be celebrating its 10th birthday soon, and controlP5 has been around longer still.
Now I must make a confession, I am the creator of G4P so am a little biased but G4P also has a visual design tool called GUI Builder. Both of these can be installed via Processing’s contribution manager also my website has extensive support for both including video guides to using GUI Builder.
That’s funny because when I first found Processing back in 2008 I thought it really needed a GUI library so I started on what became G4P and it was first released on 22nd March 2009 (almost 10 years ago) .
it was only later I discovered an existing library, controlP5. If I had discovered it earlier would I have created G4P, who knows.
No it is not. Although the discussion you link to suggests it might be possible, I have never used Python so the learning curve to make it compatible would be huge.
I am always ready to consider suggestions and although G4P comes with many examples I realise that some of them are too complex for a beginner.
If you or any other forum member would like to create some good quality examples suitable for newbies I would certainly consider including them in the next release or on the website or both. Full credit would be given to the author(s) in the sketch comments or on the website.
