#### 6.11.8.3. Details of Usage

<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" (by default is "1") attributes, which define the beginning and the end of a numerical area and a slider property step.

Example:

    <rich:inputNumberSlider></rich:inputNumberSlider>

Here is a component generated on a page:

Figure 6.159. Generated <rich:inputNumberSlider>

Using "showInput" (default value 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's displayed on a page like this:

Figure 6.160. <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 value is "true") and "showToolTip" which is responsible for tooltTip displaying (default value is "true").

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

- "onchange"

- "onmouseover"

- "onclick"

- "onfocus"

- "onmouseout"

- etc.

The "label" attribute is a generic attribute. The "label" attribute provides an association between the component and the message that the component (indirectly) produced. This attribute defines the parameters of a 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"`.

The "showArrows" boolean attribute when set to "true" enables additional controls for increasing and decreasing slider value. The controls (arrows by default) are placed in the beginning and in the end of a slider track:

Figure 6.161. <rich:inputNumberSlider> with additional controls

Clicking an arrow changes the driven value on the amount defined with "step" attribute. Keepeng an arrow control pressed changes the value continuous. Time that value takes to change from one step to another is definded with "delay" attribute.
