<section id="GUID-0381A2A3-571D-4C1D-A418-AA0C71ECB681"><title>Preview pop-up

in a touch interface</title><p>Preview pop-up is a floating component used

for displaying more detailed data about an item that has the focus in the

main pane. It is not a touch-only component, and its basic functionality is

described above. Although it is not recommended to place buttons or other

items that appear touch-enabled into the preview pop-up, it is still possible

to give some items touch-only functions. It is up to each application to decide

whether to make use of this support in some sensible way. For example, a tap

on a www hyperlink displayed in the preview pop-up would open Browser and

open the Web site in question. However, it should be noted that using touch-enabled

items in the preview pop-up is an advanced, heavy-user feature.</p><p>A tap

on an item in the preview pop-up can also open the stylus pop-up menu, when

there is no obvious direct function for that item. For more information, see <xref href="GUID-C4E728B4-3E84-49A4-83CB-DF146420D78A.dita">Stylus pop-up menu</xref>.</p></section>

<section id="GUID-BE7B9950-53D3-4BB5-8971-4CBD0D57CE51"><title>Preview pop-up

for touch only</title><p>The above section describes the general case for

touch and the preview pop-up. There is, however, a variance possibility for

the preview pop-up, which is to limit it strictly for touch. In this case,

the guideline for having no buttons or other obvious touch items in the preview

pop-up can be ignored for the most part: if the preview pop-up can only be

opened with a stylus, it is perfectly acceptable to make touch functions plainly

touch-enabled.</p></section>

<section id="GUID-AC64544E-D3D9-451C-B0EF-FF3F54B280DF"><title>Using

preview pop-ups in C++ applications</title><p>The API to use for creating

the preview pop-up component is the <xref format="html" href="specs/Guides/Information_Preview_Popup_API_Specification/Information_Preview_Popup_API_Specification.html" scope="peer">Information preview pop-up API</xref>.</p><p>Preview pop-ups

can be used in two modes: in the default mode where the pop-up is hidden automatically

as a result of time-out or input event (either a key press or a pointer event),

or in permanent mode where the pop-up stays visible until it is dismissed

by the application code. </p><p>For implementation information, see <xref format="html" href="specs/Guides/Information_Preview_Popup_API_Specification/Information_Preview_Popup_API_Specification.html#Information_Preview_Popup_API_Specification.topic3" scope="peer">Using the Information Preview Pop-up API</xref>. </p></section>
