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

<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>
