pop-up</title><prolog><metadata><keywords></keywords></metadata></prolog><conbody>

<p>The Slider pop-up component can be used for situations where a value is

changed with a slider, for example when changing zoom or volume level. The

common Slider pop-up component has a set of elements from which to select

and modify the slider in question, e.g. value ranges, whether to have current

value as text included, or additional icons related to the slider.</p>

<p>For application specific slider pop-up the application may define ways

to open the pop-up. For common pop-up such as Volume Control, ways to open

the pop-up are defined. The Slider pop-up has default timeout after which

it disappears, but for good reason this timeout can be overridden by the application. </p>

<p>Instead of using the pop-up, the application may define the slider to be

always visible i.e. fixed in the layout. If slider is fixed in the layout,

the pop-up is not shown.</p>

<p>The orientation of the slider pop-up can be either horizontal or vertical.

The orientation and location are always the same across applications, unless

application uses the slider as fixed in the layout. Value growth direction

in Slider is always either up or right depending on the Slider orientation

in the UI. </p>
