Theming allows us to adapt the look of an application in a similar way to CSS while styling allows us to do so within the code. In this tutorial I cover only a small fraction of the subject matter but after going thru it you should have a decent understanding of the forces at play and the tools you can use.Read More
Until this weeks release push notification was registered using
Display.registerPush(Hashtable, boolean) the thing is that both of these arguments to that method are no longer used or not the best way to implement registration. So we deprecated that method and introduced a new version of the method
One of the key takeaways I have from the bootcamp is the need to work on TDD in Codename One. We had a test framework and test recording framework for years, but it wasn't picked up by many developers and as such it stagnated. As we launched the
Toolbar API we didn't even check that framework and some basic stuff stopped working.
Tracking & logging errors is crucial for a stable application. There are several tools we offer in Codename One both in the seamless level (crash protection) and in the lower level inner workings of Codename One. I'll try to explain both and how they interact.Read More
Layouts are one of the hardest subjects to grasp in Codename One, there is a lot of nuance in getting layouts "right". Since the subject is so vast and complex this video only scratches the surface and is still relatively long for an introductory video. It's crucial to go thru this material though if you are not familiar with layouts or find them confusing.Read More
Recently I sent a build and had an issue installing it. It was late at night and I just forgot to add the build hint
ios.debug.archs=armv7 for installation on the 3rd gen iPad I was testing with. So we can all trip over basic mistakes when it comes to iOS installs. So for your convenience I made a list of common pitfalls you might run into if your iOS build won't install on your device.
This feature is still undergoing development but I wanted to share the progress here so we can start getting bug reports and suggestions. One of the frequent requests for the side menu UI is to provide a way for it to render on top of the UI instead of shift the UI. The old side menu was written when the facebook app was the chief application that used that UI paradigm so it was built to match that approach.Read More
I'm a bit conflicted about this tip. The
AutoCompleteTextField is a problematic class that is in dire need of a rewrite. When we created it we still didn't accept that lists "need to go". It also predated features like the
InteractionDialog which would have made this component much easier to use.
One of the biggest challenges facing new Codename One developers is the challenge of creating an elegant looking UI. This isn't trivial in any tool but we don't make it easy enough in some cases. In the tutorial below I'm focusing on one of the most important UI elements: the side menu.Read More
