UI toolkit

The UI toolkit contains a set of views for designing applications that can run on multiple device types, such as mobile and desktop devices. All the views in the UI toolkit are suitable for use on both desktop and mobile devices.
Each view points to a specific set of files:
  • A JavaScript file that provides the behavior of the view
  • Image files to represent the view on the palette and on the canvas
  • A preview JavaScript file that shows a preliminary image of the view
The view can also have other files such as CSS and LESS files for styling, localization files and other view specific resource files, but these additional files are optional.
