Hinweis der Redaktion
- Multiple operating systems by a large set of vendors (-> next slide) Infact we have the slides for desktop fragmentation as well, but this is a mobile conference, right?
- Interesting market with a lot of competetion. Good for the customer. Bad for the developer.
- Even 6 are imaginable... oops
- Pause...
- That makes us different from a lot of cross platform web projects. We really want the user to not see any difference to native applications.
- So I like to start with platforms we definitely do not support. Infact we excluded these from the very beginning and focused on the modern platforms instead.
- We use it for JavaScript OO, event system etc. on mobile and for widgets on desktops
- Enhancing the feature set of web applications on mobile devices.
- Supercharged CSS
- The standard for building desktop web applications.
- Thanks to T-Labs for their help to bring BONDI standards to PhoneGap.
- Let‘s focus on the Unify specific features here...
- Here you can take a quick look on some of our components. Basically we do not create components for every single element and wrap every HTML element. I guess that would be too expensive. We just wrap elements which have some kind of non-HTML functionality.
- One thing which was invisible on the previous slide are layers. A layer is basically a DOM element which includes all specific content for the current location in the application.
- Layers are used to animate from one location to another. This way the user get a feeling of where in the structure of the application he resides.
- Each layer which has a parent also comes with a back button (or close button on modal layers)
- Layers are shared. A layer which shows the timeline is only creates once and updated according to the position in the application and/or an optional parameter.
- The ViewManager controls the visible view/layer. The LayerManager manages state changes between layers (controls animations, zIndex, etc.) Each view has one exclusive layers.
- We started with the visible things (controls). Now let‘s get a little bit deeper. Layers are managed by the LayerManager which is itself controlled by the ViewManager.
- Ever used the wheather app on the iPhone?
