-/**
- * Class TAccordion.
- *
- * TAccordion displays an accordion control. Users can click on the view headers to switch among
- * different accordion views. Each accordion view is an independent panel that can contain arbitrary content.
- *
- * A TAccordion control consists of one or several {@link TAccordionView} controls representing the possible
- * accordion views. At any time, only one accordion view is visible (active), which is specified by any of
- * the following properties:
- * - {@link setActiveViewIndex ActiveViewIndex} - the zero-based integer index of the view in the view collection.
- * - {@link setActiveViewID ActiveViewID} - the text ID of the visible view.
- * - {@link setActiveView ActiveView} - the visible view instance.
- * If both {@link setActiveViewIndex ActiveViewIndex} and {@link setActiveViewID ActiveViewID}
- * are set, the latter takes precedence.
- *
- * TAccordion uses CSS to specify the appearance of the accordion headers and panel. By default,
- * an embedded CSS file will be published which contains the default CSS for TTabPanel.
- * You may also use your own CSS file by specifying the {@link setCssUrl CssUrl} property.
- * The following properties specify the CSS classes used for elements in a TAccordion:
- * - {@link setCssClass CssClass} - the CSS class name for the outer-most div element (defaults to 'accordion');
- * - {@link setHeaderCssClass HeaderCssClass} - the CSS class name for nonactive accordion div elements (defaults to 'accordion-header');
- * - {@link setActiveHeaderCssClass ActiveHeaderCssClass} - the CSS class name for the active accordion div element (defaults to 'accordion-header-active');
- * - {@link setViewCssClass ViewCssClass} - the CSS class for the div element enclosing view content (defaults to 'accordion-view');
- *
- * When the user clicks on a view header, the switch between the old visible view and the clicked one is animated.
- * You can use the {@link setAnimationDuration AnimationDuration} property to set the animation length in seconds;
- * it defaults to 1 second, and when set to 0 it will produce an immediate switch with no animation.
- *
- * The TAccordion auto-sizes itself to the largest of all views, so it can encompass all of them without scrolling.
- * If you want to specify a fixed height (in pixels), use the {@link setViewHeight ViewHeight} property.
- * When a TAccordion is nested inside another, it's adviced to manually specify a {@link setViewHeight ViewHeight} for the internal TAccordion
- *
- * To use TAccordion, write a template like following:
- * <code>
- * <com:TAccordion>
- * <com:TAccordionView Caption="View 1">
- * content for view 1
- * </com:TAccordionView>
- * <com:TAccordionView Caption="View 2">
- * content for view 2
- * </com:TAccordionView>
- * <com:TAccordionView Caption="View 3">
- * content for view 3
- * </com:TAccordionView>
- * </com:TAccordion>
- * </code>

Each accordion view is an independent panel that can contain arbitrary content. + * + * A TAccordion control consists of one or several {@link TAccordionView} controls representing the possible + * accordion views. At any time, only one accordion view is visible (active), which is specified by any of + * the following properties: + * - {@link setActiveViewIndex ActiveViewIndex} - the zero-based integer index of the view in the view collection. + * - {@link setActiveViewID ActiveViewID} - the text ID of the visible view. + * - {@link setActiveView ActiveView} - the visible view instance. + * If both {@link setActiveViewIndex ActiveViewIndex} and {@link setActiveViewID ActiveViewID} + * are set, the latter takes precedence. + * + * TAccordion uses CSS to specify the appearance of the accordion headers and panel. By default, + * an embedded CSS file will be published which contains the default CSS for TTabPanel. + * You may also use your own CSS file by specifying the {@link setCssUrl CssUrl} property. + * The following properties specify the CSS classes used for elements in a TAccordion: + * - {@link setCssClass CssClass} - the CSS class name for the outer-most div element (defaults to 'accordion'); + * - {@link setHeaderCssClass HeaderCssClass} - the CSS class name for nonactive accordion div elements (defaults to 'accordion-header'); + * - {@link setActiveHeaderCssClass ActiveHeaderCssClass} - the CSS class name for the active accordion div element (defaults to 'accordion-header-active'); + * - {@link setViewCssClass ViewCssClass} - the CSS class for the div element enclosing view content (defaults to 'accordion-view'); + * + * When the user clicks on a view header, the switch between the old visible view and the clicked one is animated. + * You can use the {@link setAnimationDuration AnimationDuration} property to set the animation length in seconds; + * it defaults to 1 second, and when set to 0 it will produce an immediate switch with no animation. + * + * The TAccordion auto-sizes itself to the largest of all views, so it can encompass all of them without scrolling. + * If you want to specify a fixed height (in pixels), use the {@link setViewHeight ViewHeight} property. + * When a TAccordion is nested inside another, it's adviced to manually specify a {@link setViewHeight ViewHeight} for the internal TAccordion + * + * To use TAccordion, write a template like following: + * <code> + * <com:TAccordion> + * <com:TAccordionView Caption="View 1"> + * content for view 1 + * </com:TAccordionView> + * <com:TAccordionView Caption="View 2"> + * content for view 2 + * </com:TAccordionView> + * <com:TAccordionView Caption="View 3"> + * content for view 3 + * </com:TAccordionView> + * </com:TAccordion> + * </code> + * + * @author Gabor Berczi, DevWorx Hungary <gabor.berczi@devworx.hu> + * @version $Id: TAccordion.php 2915 2011-05-15 16:26:11Z ctrlaltca@gmail.com $ + * @package System.Web.UI.WebControls + * @since 3.2 + */ + +class TAccordion extends TWebControl implements IPostBackDataHandler +{ + private $_dataChanged=false; + + /** + * @return string tag name for the control + */ + protected function getTagName() + { + return 'div'; + } + + /** + * Adds object parsed from template to the control. + * This method adds only {@link TAccordionView} objects into the {@link getViews Views} collection. + * All other objects are ignored. + * @param mixed object parsed from template + */ + public function addParsedObject($object) + { + if($object instanceof TAccordionView) + $this->getControls()->add($object); + } + + /** + * Returns the index of the active accordion view. + * Note, this property may not return the correct index. + * To ensure the correctness, call {@link getActiveView()} first. + * @return integer the zero-based index of the active accordion view.
