A component that lets selecting a number from a numeric region. It's a horizontal aligned scroll-like control with its own input field (optional) present. The keyboard input in a field is possible (optional). Also it's possible to see the current value in the toolTip above a dragged handle control.

To create the simplest variant on a page use the following syntax:

Example:

...

    <rich:inputNumberSlider minValue="0" maxValue="100" step="1"/>  

...

Example:

import org.richfaces.component.html.HtmlInputNumberSlider;

...

HtmlInputNumberSlider mySlider = new HtmlInputNumberSlider();

...

<rich:inputNumberSlider> is used to facilitate your data input with rich UI Controls.

Here is the simplest variant of a slider definition with "minValue", "maxValue" and "step" (on default = "1") attributes, which define the beginning and the end of a numerical area and a slider property step.

Example:

<rich:inputNumberSlider></rich:inputNumberSlider>

It generates on a page:

Using "showInput" (default is true) and "enableManualInput" (default value is true) attributes, it's possible to output the input area near the slider, and make it read-only or editable.

To remove input area use "showInput="false" :

Example:

<rich:inputNumberSlider minValue="1"  maxValue="100" showInput="false"/>

It looks at page like:

Figure 6.92.  <rich:inputNumberSlider> without input field

It's also possible to switch off displaying of "boundary values" and a toolTip showing on a handle drawing. This could be performed with the help of the component defined attributes: "showBoundaryValues" which is responsible for "boundary values" displaying (default is true) and "showToolTip" which is responsible for tooltTip displaying (default is true).

Moreover, to add e.g. some JavaScript effects, events defined on it are used.

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for “DoubleRangeValidator.MAXIMUM”, {2} for “ShortConverter.SHORT”.

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:inputNumberSlider> components at once:

On the screenshot there are classes names that define styles for component elements.

Figure 6.93. Style classes

In order to redefine styles for all <rich:inputNumberSlider> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the table above) and define necessary properties in them. An example is placed below:

Example:

...

.rich-inslider-tip{

    background-color: #FFDAB9;

    font-family: Arial Black;

}  

...

This is a result:

Figure 6.94. Redefinition styles with predefined classes

In the example a tip background color and font family was changed.

Also it’s possible to change styles of particular <rich:inputNumberSlider> component. In this case you should create own style classes and use them in corresponding <rich:inputNumberSlider> styleClass attributes. An example is placed below:

Example:

...

.myClass{

    font-style: italic;

    font-weight:bold;

    font-size:12px;

}

...

The "inputClass" attribute for <rich:inputNumberSlider> is defined as it’s shown in the example below:

Example:

<rich: inputNumberSlider ... inputClass="myClass"/>

This is a result:

Figure 6.95. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for input text was changed.

Here you can see the example of <rich:inputNumberSlider> usage and sources for the given example.
