Employment/Purpose

A slider component represents a slider with a scale and a knob. It can be used to let user select a value by sliding the knob along the scale. A slider accepts a range of value starting from 0 to certain maximum value. The default maximum value of slider scale is 100. You could change the maximum allowed value by the maxpos property. However the default minimum is 0 and cannot be changed.

Example

  <slider id="slider" orient="vertical"/>
  <slider curpos="1" maxpos="20"  />

Page Increment

By default, the slider will move to the position of the try on which an user clicks. If you prefer to move in a fixed amount (like the scrollbar does), you could specify the amount of value to move by use of Slider.setPageIncrement(int).

  <slider pageIncrement="10"/>

Supported Events

Name	Event Type
onScroll	Event: ScrollEvent Denotes the content of a scrollable component has been scrolled by the user.
onScrolling	Event: ScrollEvent Denotes that the user is scrolling a scrollable component. Notice that the component's content (at the server) won't be changed until onScroll is received. Thus, you have to invoke the getPos method in the ScrollEvent class to retrieve the temporary position.

• Inherited Supported Events: XulElement

Available molds of a component are defined in lang.xml embedded in zul.jar.
