I got a question the other day about a UI design for an upcoming Codename One app. In this UI the title floated on top of the content as the content scrolled past and tabs were a part of the title area in the style of material design.
Our tabs component predated material design by many years and wasn't designed for this sort of UI. When you scroll out of a tab it scrolls out. Using it for this sort of UI doesn't make much sense. The solution was to use a custom title area with two toggle radio buttons representing each tab with a line below to indicate the selected button.
I've mentioned before that our biggest priority in 3.8 is refining the UI design of Codename One applications. This is a difficult task as it is so vague. There are so many small things we can do, when they are viewed in unison they seem approachable but as we start going thru the tasks priorities muddle. That's why we need feedback from you guys on what bothers you about the UI and its refinement.Read More
We were prepared for an uphill effort in terms of getting Kotlin up and running... Turns out that getting the basic support out of the door was much easier than expected with a few expected caveats that will hopefully be acceptable moving forward. Steve did pretty much all of the work on this, I asked him to write a post where he explains the challenges as this isn't the first time he ported a JVM language to Codename One.Read More
On occasion I answer a question on stackoverflow, the discussion forum or elsewhere and I get a response of the form of: "this wasn't clear from the docs". We improved the docs but befitting a huge project run by engineers without a technical writer in sight this is a bit of a problem... The thing is that this is a problem you can fix regardless of your level in engineering or in English.Read More
Push gets a lot of support queries, it's a hard subject to wrap your head around especially with all of the conflicting and shifting landscape around it. To make matters worse every OS conceptualizes it very differently. I go into some of the really advanced stuff such as fallback behavior in the advanced course but basic stuff is still a crucial first step.Read More
I wrote in the past about importing a Codename One demo from github but I left the whole working with git as an open subject. Mostly because I considered it a bit out of scope for the discussion. I have a section in the free online course about the anatomy of a Codename One application which I completely forgot to upload until I wrote this!Read More
