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>
