<concept id="GUID-D0F6E95B-B35A-4EA1-8CC3-D86D1E0E6DD3" xml:lang="en"><title>Creating
stylus pop-up menu</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>Construct the menu using the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknStylusPopUpMenu.html#9dda70f72d42d0877cbbf9ca299649af" format="application/java-archive"><codeph>NewL()</codeph></xref>in the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknStylusPopUpMenu.html" format="application/java-archive"><codeph>CAknStylusPopUpMenu</codeph></xref>.</p>
<note> <p>The last parameter in the constructor is a pointer to the preview
pop-up from which the stylus pop-up menu is launched. If you are not constructing
a pop-up menu for a preview pop-up, set the parameter as <codeph>NULL</codeph>.</p></note>
<p>To construct the menu from a resource, use the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknStylusPopUpMenu.html#75cd95c35a6ed4734b93713596bb51d5" format="application/java-archive"><codeph>CAknStylusPopUpMenu::ConstructFromResourceL()</codeph></xref>.</p>
<p>The following example illustrates a stylus pop-up menu opened in the location
(not a preview pop-up) where the user taps with the stylus as well as the
resource that defines the menu items:</p>
<note><p>The menu is constructed only once: when <codeph>HandlePointerEventL</codeph> runs
for the first time. Later the already constructed menu is shown again.</p></note>
