<p>A setting list is a specific kind of selection list containing setting
items that the user can adjust. Setting lists are displayed in the main pane.</p>

<p>A setting item can be adjusted by selecting it in the same way as selection
list items are selected in general; that is, by pressing the Selection key,
or choosing the Change command from the Options menu. The main pane then displays
the setting item editor where the value can be changed.</p>
<p>There are several setting item types available. They look the same in the
setting list: each item displays an attribute text (the title of the setting)
on one line and the current value on another line within the item. The adjusting
and editing functions differ between the setting item types.</p>

<entry><p>Pop-up setting</p></entry>
<entry><p>A pop-up setting allows the user to choose one value from a pre-defined
list. The setting editor displays the available values in a menu list.A pop-up
setting may also allow the user to enter a new textual value in addition to
the pre-defined values. In that case, the last option is named Other (or equivalent),
and selecting it opens a Data query for entering the new value.</p></entry>

<row>
<entry><p>Multi-selection list setting</p></entry>
<entry><p>A multi-selection list setting allows the user to choose several
simultaneous values from a pre-defined list. The setting editor displays the
available values as a multi-selection list. The setting item displays the
number of selected items versus all the items in the value field; for example:
3/8.</p></entry>
</row>
<row>
<entry><p>Text setting</p></entry>
<entry><p>The value of a text setting item is an alphanumeric or numeric string.
The editor can be of a specific type, such as the Date and Time editor.</p></entry>

<entry><p>Slider setting</p></entry>
<entry><p>With a slider, the user can adjust the value of a setting by sliding
a marker. The value of a slider is adjusted using the Arrow left and Arrow
right keys.</p></entry>

<p>In the setting editor, the Navi pane is empty, or in case of a text editor,
contains the editing indicators.</p>
<p>Further guidelines:</p>
<ul>
<li><p>Typically, a setting list is accessed via the <b>Options</b> menu (see <xref href="GUID-BFEEECCA-190B-4DDE-8A04-4FE918BE8690.dita">Options menu</xref>). </p></li>
<li><p>Setting lists can only contain setting items, not other types of items
mixed with them. (In case the settings are arranged in a hierarchical structure,
both setting items and setting folders may exist in one list.)</p></li>
<li><p>All the setting item types can co-exist in the same setting list.</p></li>
</ul>
<p>If a pop-up setting has only two available values (such as <b>On</b> and <b>Off</b>)
and no special procedure is needed when switching from one value to the other,
then the setting editor (list) must not be displayed when the user presses
the Selection key; the item's value is changed immediately. However, if the
user opens the setting item via the <b>Options</b> menu, or if an additional
procedure is required (for example a password) before the item's value can
be changed, the list is opened normally.</p>
<section><title>Using setting lists in
C++ applications</title><p>The APIs to use for setting lists are the Lists
API and the Setting
pages API. For implementation information, see Using
the Lists API and Using
the Setting pages API.</p></section>
