New GXT 4 Features
GXT 4 includes tablet support by introducing the touch and gesture system at the core of the framework. It also introduces a new theme, Triton, that is designed to work across desktop and tablet devices. Below are some highlights of the tablet support and Triton theme in GXT 4.
Tablet Support with Touch Gestures
GXT 4 provides support for devices with touch-screen input, including tablets and touch-screen laptops. This allows existing GXT applications to run on touch-screen devices with little or no modification. Support for devices with touch-screens can be broken down into two categories.
- Gesture System – which combines native browser events such as touchstart, touchmove, and touchend, and synthesizes them into gestures. Upon interpreting the sequence and timing of these touch events, the system recognizes more complex gestures such as drag, swipe, longpress, pinch, rotate, and tap.
- Touch Scroller (Momentum Scrolling) – for mobile (tablet) browsers, which improves the scrolling experience on touch sensitive devices.
Most complex UI components in GXT such as Grid, TreeGrid, Tree, and Data View are now optimized for a better scrolling experience on touch-enabled devices.
New Triton Theme
While adding Touch and Gesture support to GXT, we wanted to create a new theme that is optimized for a tablet application experience. Given the transition from a mouse and click interface on desktop devices to a touch-based interaction, we needed to enable the use of a wider contact surface (fingertips) on tablets. We’re introducing a new Triton theme in GXT 4 (inspired by Triton in Ext JS 6), which is a common new theme available for both desktop and tablet applications.
We’re proud to release this early access version to the community and continue to evolve GXT as the best way to deliver robust Java-based HTML5 applications for desktops and tablets. Read What’s New in GXT 4 for a complete view of all the new features.
