UI</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>When designing a Symbian application, the UI must be designed so that all

tasks can be performed with touch. Therefore, the design must not rely on

hardware keys (except for turning the power ON and OFF).  </p>

<p>The touch UI in the Symbian platform involves various specific touch components,

component and UI behavior changes, layout changes and additions to the <xref href="GUID-0D093C3D-4D85-455E-B685-064A9B25B1FE.dita">user experience</xref>. The

main differences or additions in touch UI include the following:</p>

<ul>

<li><p>Resistive touch screen (HW).</p><p> For more information, see <xref href="GUID-1FCD0312-7B28-47F9-BE54-822B74A8934C.dita">Designing applications for

touch UI</xref></p></li>

<li><p>Capacitive touch screen (HW). </p><p>For more information, see <xref href="GUID-1FCD0312-7B28-47F9-BE54-822B74A8934C.dita">Designing applications for

touch UI</xref></p></li>

<li><p>Single tap. For more information, see <xref href="GUID-F66AC845-58B8-4029-AE04-C283226B7C12.dita">Single

tap</xref>.</p></li>

<li><p>Multi-touch</p>.<p>For more information, see <xref href="GUID-17C64C2F-9426-4B41-9F0A-23060289D644.dita">Multi-touch</xref>.</p></li>

<li><p>Toolbar component in touch UI</p><p>For

more information, see <xref href="GUID-EB212C35-5416-4CA7-8091-61B45D78E220.dita">Toolbar</xref>.</p></li>

<li><p>Touch input component (virtual keyboard, hand-writing recognition and

virtual ITU-T) </p><p>For more information,

see <xref href="GUID-57B7DA8C-A62F-4C65-B754-47D9F5E76416.dita">Text

input</xref>.</p></li>

<li><p>Stylus pop-up menu component </p><p>For

more information, see <xref href="GUID-C4E728B4-3E84-49A4-83CB-DF146420D78A.dita">Stylus

pop-up menu</xref>.</p></li>

<li><p>On-screen dialer application </p></li>

<li><p>Additional touch functionality to some components (for example, Preview

pop-up) </p><p>For more information,

see <xref href="GUID-E7EFAD50-3323-49A6-A5D9-95B95F0FBF0E.dita">Preview

more information, see <xref href="GUID-BB8B3A11-0BBC-4759-A7F4-A28C9E70573F.dita">Touch

support for UI components</xref>.</p></li>

</ul>

<p>There are two generic layouts for touch UI -portrait orientation and landscape

orientation, see the following figure. The <xref href="GUID-771AF721-E2D7-41C8-BF97-5BD30D1A28AD.dita">Status

pane</xref> in Touch UI has three variants: extended, flat and small.</p>
