API</title><shortdesc>The Toolbar API is used for enabling quick access to functions

by displaying them in a toolbar.</shortdesc><prolog><metadata><keywords></keywords></metadata></prolog><conbody>

<p>A toolbar contains Avkon buttons. The toolbar supports touch, and can be

with focus or without focus. It contains application-specific buttons (at

least three) that launch application-specific commands. The toolbar content

is application-specific, but you can choose whether the toolbar is displayed

in an application view or not.</p>

<p>The Toolbar API supports two types of toolbars: a fixed toolbar for touch

UI, and a floating toolbar which can also be used in non-touch UIs.</p>

<p>The fixed toolbar doesn’t have focus, whereas the floating toolbar owns

the focus and it can be used also with navigation and selection keys. By default,

the floating toolbar owns the CBA buttons (<uicontrol>Select</uicontrol> and <uicontrol>Close</uicontrol>)

but the floating toolbar can be defined as not having the CBA buttons with

suitable flags. </p>

<p>The toolbars are also located differently: a fixed toolbar has a permanent

place in the layout but a floating toolbar can be freely located when it is

defined as having a flexible position.</p>

<p>The toolbar extension is a toolbar button that expands the fixed or floating

toolbar. When the extension button is pressed, a grid of toolbar items opens

up. The extension items can be used as actual toolbar items. </p>

<p>The extension button itself looks like an ordinary toolbar button. The

only difference is that there is a default icon for the extension button that

is shown if the application does not change the icon itself.</p>
