8 * @class Ext.layout.AccordionLayout
\r
9 * @extends Ext.layout.FitLayout
\r
10 * <p>This is a layout that manages multiple Panels in an expandable accordion style such that only
\r
11 * <b>one Panel can be expanded at any given time</b>. Each Panel has built-in support for expanding and collapsing.</p>
\r
12 * <p>Note: Only Ext.Panels <b>and all subclasses of Ext.Panel</b> may be used in an accordion layout Container.</p>
\r
13 * <p>This class is intended to be extended or created via the <tt><b>{@link Ext.Container#layout layout}</b></tt>
\r
14 * configuration property. See <tt><b>{@link Ext.Container#layout}</b></tt> for additional details.</p>
\r
15 * <p>Example usage:</p>
\r
17 var accordion = new Ext.Panel({
\r
18 title: 'Accordion Layout',
\r
21 // applied to each contained panel
\r
22 bodyStyle: 'padding:15px'
\r
25 // layout-specific configs go here
\r
26 titleCollapse: false,
\r
32 html: '<p>Panel content!</p>'
\r
35 html: '<p>Panel content!</p>'
\r
38 html: '<p>Panel content!</p>'
\r
43 Ext.layout.AccordionLayout = Ext.extend(Ext.layout.FitLayout, {
\r
45 * @cfg {Boolean} fill
\r
46 * True to adjust the active item's height to fill the available space in the container, false to use the
\r
47 * item's current height, or auto height if not explicitly set (defaults to true).
\r
51 * @cfg {Boolean} autoWidth
\r
52 * True to set each contained item's width to 'auto', false to use the item's current width (defaults to true).
\r
53 * Note that some components, in particular the {@link Ext.grid.GridPanel grid}, will not function properly within
\r
54 * layouts if they have auto width, so in such cases this config should be set to false.
\r
58 * @cfg {Boolean} titleCollapse
\r
59 * True to allow expand/collapse of each contained panel by clicking anywhere on the title bar, false to allow
\r
60 * expand/collapse only when the toggle tool button is clicked (defaults to true). When set to false,
\r
61 * {@link #hideCollapseTool} should be false also.
\r
63 titleCollapse : true,
\r
65 * @cfg {Boolean} hideCollapseTool
\r
66 * True to hide the contained panels' collapse/expand toggle buttons, false to display them (defaults to false).
\r
67 * When set to true, {@link #titleCollapse} should be true also.
\r
69 hideCollapseTool : false,
\r
71 * @cfg {Boolean} collapseFirst
\r
72 * True to make sure the collapse/expand toggle button always renders first (to the left of) any other tools
\r
73 * in the contained panels' title bars, false to render it last (defaults to false).
\r
75 collapseFirst : false,
\r
77 * @cfg {Boolean} animate
\r
78 * True to slide the contained panels open and closed during expand/collapse using animation, false to open and
\r
79 * close directly with no animation (defaults to false). Note: to defer to the specific config setting of each
\r
80 * contained panel for this property, set this to undefined at the layout level.
\r
84 * @cfg {Boolean} sequence
\r
85 * <b>Experimental</b>. If animate is set to true, this will result in each animation running in sequence.
\r
89 * @cfg {Boolean} activeOnTop
\r
90 * True to swap the position of each panel as it is expanded so that it becomes the first item in the container,
\r
91 * false to keep the panels in the rendered order. <b>This is NOT compatible with "animate:true"</b> (defaults to false).
