- Accordions serve a similar purpose to tab panes and card panes, only showing one
- of a collection of components at a time. Like tab panes, accordions provide built-in
- navigation support. However, rather than representing the content as a stack of
- components, they are presented like the folds of an accordion, with headers for
- navigating between panels.
- </p>
- <p>
- The following application demonstrates the use of the <tt>Accordion</tt> component.
- It is a simplified online checkout process consisting of three pages - shipping
- info, payment info, and order summary:

-
- <p>
- Note that, like <tt>TabPane</tt>, the default behavior of an accordion is to allow
- the user to freely navigate between panels. However, in this example, the user is
- only allowed to progress forward in the accordion by pressing the "Next" button.
- This restriction is imposed programmatically by the application, since the content
- of a subsequent page in such a checkout process may depend on the user's entries on
- a previous page. The user may freely navigate backward at any point, however.
- The last panel simulates the order confirmation by displaying an
- <a href="activity-indicators.html">activity indicator</a>.
- </p>
-
- <p>
- The BXML source for the example is shown below. It includes a number of external BXML
- files that define the content of each panel:
- </p>
-
- <pre class="brush:xml">
-
- <navigation:Accordions title="Accordions" maximized="true"
- xmlns:bxml="http://pivot.apache.org/bxml"
- xmlns:navigation="org.apache.pivot.tutorials.navigation"
- xmlns="org.apache.pivot.wtk">
- <Accordion bxml:id="accordion" styles="{padding:0}">
- <bxml:include bxml:id="shippingPanel" src="shipping.bxml" Accordion.headerData="Shipping Information"/>
- <bxml:include bxml:id="paymentPanel" src="payment.bxml" Accordion.headerData="Payment Information"/>
- <bxml:include bxml:id="summaryPanel" src="summary.bxml" Accordion.headerData="Summary &amp; Confirmation"/>
- </Accordion>
- </navigation:Accordions>
-
- </pre>
-
- <p>
- The Java source is as follows. The primary logic for maintaining the enabled state
- of the panels is defined in the <tt>updateAccordion()</tt> method; an
- <tt>AccordionSelectionListener</tt> is used to enable or disable panels when a
- selection change transition is about to occur, rather than waiting until it is
- complete, to provide a smoother user experience:

+ This restriction is imposed programmatically by the application, since the content
+ of a subsequent page in such a checkout process may depend on the user's entries on
+ a previous page. The user may freely navigate backward at any point, however.
+ The last panel simulates the order confirmation by displaying an
+ <a href="activity-indicators.html">activity indicator</a>.
+ </p>
+
+ <p>
+ The BXML source for the example is shown below. It includes a number of external BXML
+ files that define the content of each panel:
+ </p>
+
+ <pre class="brush:xml">
+
+ <navigation:Accordions title="Accordions" maximized="true"

+
+ <p>
+ The Java source is as follows. The primary logic for maintaining the enabled state

- Activity indicators are used to present an indeterminate progress state. They inform
- the user that a background task is in progress, but that the length of the task is
- not known. For example, an application might use an activity indicator to reflect
- network activity, a file load operation, or a long-running CPU operation. They are
- often animated to simulate the appearance of progress and to let the user know that
- the UI is still responsive.
- </p>
-
- <p>
- In Pivot, activity indicators are represented by instances of the
- <tt>ActivityIndicator</tt> component, shown below:

+ Activity indicators are used to present an indeterminate progress state. They inform
+ the user that a background task is in progress, but that the length of the task is
+ not known. For example, an application might use an activity indicator to reflect
+ network activity, a file load operation, or a long-running CPU operation. They are
+ often animated to simulate the appearance of progress and to let the user know that
+ the UI is still responsive.
+ </p>
+
+ <p>
+ In Pivot, activity indicators are represented by instances of the
+ <tt>ActivityIndicator</tt> component, shown below:
