Question

I want to implement slider with two knobs in GWT? Can anyone help me?

Answer 1

If you don’t mind going with third-party library there is JQuery wrapper: spiffyui (demo) and it has Slider.java. Here is what it does:

/**
 * This widget wraps the JQuery UI Slider
 * and allows for single slider or double slider with range.
 * 
 * All options can be get or set using generic 
 * get/setIntOption, get/setStringOption, get/setBooleanOption
 * methods, but some convenience methods are provided for most popular such as
 * setValues and setMinimum and setMaximum.  See SliderOptions for full list of options.
 * @see SliderOption
 */
