<p>A form is a specific kind of selection list, where all items (fields) have
some editable content. </p>
<p>A form can be in the View state or in the Edit state. The item layouts
and functionality are different in these states:</p>
<ul>
<li><p>In the View state, the items are not editable. The form functions and
looks exactly like a similar selection list. Items can be selected to perform
an application-specific function. </p></li>
<li><p>In the Edit state, the user can edit all the fields. Forms can contain
text fields (alphanumeric or numeric content), pop-up fields and sliders.</p></li>
</ul>
<p>Forms work with single click. The view state of the form follows list behavior.
Edit state works with single click but it has the highlight always visible
to indicate the active form item. Note that the entire form component item
should be touch sensitive in normal state. This means that even if the user
does not touch the edit field but instead the field header, the item is still
activated.</p>
<p>The user can switch from the View state to the Edit state using the Edit
command in the Options menu. In the Edit state, the contents of the form can
be accepted using the right softkey labeled as Done. The form then returns
to the View state.</p>

forms in C++ applications</title><p>The API to use for creating forms is the <xref format="html" href="specs/guides/Form_API_Specification/Form_API_Specification.html" scope="peer">Form API</xref>. For implementation information, see <xref format="html" href="specs/guides/Form_API_Specification/Form_API_Specification.html#Form_API_Specification.topic3" scope="peer">Using the Form API</xref>.</p><p>Typically, a form will be derived
from the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknForm.html" format="application/java-archive"><codeph>CAknForm</codeph></xref> and

These are called when users
switch from edit mode to view mode and are prompted by the form as to whether
they wish to save their modifications.</p><p>For customization, the class <codeph>CAknForm</codeph> provides
a single-line or double-line layout and it is possible to use icons on forms. </p><p>In
the following example, the form is pushed on the cleanup stack before <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknForm.html#a7108b30a367ecb940f57e0dd35973bd" format="application/java-archive"><codeph>ConstructL()</codeph></xref> (a
