UI Component Infrastructure Modules: Managing Component Properties

The Elementary library is composed of many UI components to support Tizen native applications. While using UI components, you must manage their common properties. To meet this requirement, Elementary creates some infrastructure modules in order to support many UI components. Currently, Elementary provides following infrastructure modules:

• Component focus

  A UI component application always has 1 focused object, which is selected to receive input from the user. The focus can change between objects, and the focused object can be decorated on the screen to make it easily visible.

• Handling touch gestures for components

  UI components generally handle basic touch inputs, such as press, release and moving. However, in some use cases (for example, when the accessibility Assistive Technology (AT) client is working), handling for a variety of touch gesture events (such as tap, double-tap, triple-tap, double-tap and hold, and left/right/up/down swipe) is needed. Elementary can also create new touch gesture patterns according to application use cases.

• Customizing components

  Elementary provides basic UI components based on the Tizen UX styles which you can use. Usually, you can use the supported UI components themselves to make your application. However, if you need to use other styles than the basic ones, you must customize the UI component style.

• UI mirroring

  Elementary provides UI mirroring, which allows you to set UI mirroring on specific UI components or the whole interface. This facility is very useful to support applications which need both right-to-left and left-to-right languages.
