16 * @class Ext.BoxComponent
17 * @extends Ext.Component
18 * <p>Base class for any {@link Ext.Component Component} that is to be sized as a box, using width and height.</p>
19 * <p>BoxComponent provides automatic box model adjustments for sizing and positioning and will work correctly
20 * within the Component rendering model.</p>
21 * <p>A BoxComponent may be created as a custom Component which encapsulates any HTML element, either a pre-existing
22 * element, or one that is created to your specifications at render time. Usually, to participate in layouts,
23 * a Component will need to be a <b>Box</b>Component in order to have its width and height managed.</p>
24 * <p>To use a pre-existing element as a BoxComponent, configure it so that you preset the <b>el</b> property to the
25 * element to reference:<pre><code>
26 var pageHeader = new Ext.BoxComponent({
29 * This may then be {@link Ext.Container#add added} to a {@link Ext.Container Container} as a child item.</p>
30 * <p>To create a BoxComponent based around a HTML element to be created at render time, use the
31 * {@link Ext.Component#autoEl autoEl} config option which takes the form of a
32 * {@link Ext.DomHelper DomHelper} specification:<pre><code>
33 var myImage = new Ext.BoxComponent({
36 src: '/images/my-image.jpg'
40 * @param {Ext.Element/String/Object} config The configuration options.
43 Ext.BoxComponent = Ext.extend(Ext.Component, {
45 // Configs below are used for all Components when rendered by BoxLayout.
46 <div id="cfg-Ext.BoxComponent-flex"></div>/**
48 * <p><b>Note</b>: this config is only used when this Component is rendered
49 * by a Container which has been configured to use a <b>{@link Ext.layout.BoxLayout BoxLayout}.</b>
50 * Each child Component with a <code>flex</code> property will be flexed either vertically (by a VBoxLayout)
51 * or horizontally (by an HBoxLayout) according to the item's <b>relative</b> <code>flex</code> value
52 * compared to the sum of all Components with <code>flex</flex> value specified. Any child items that have
53 * either a <code>flex = 0</code> or <code>flex = undefined</code> will not be 'flexed' (the initial size will not be changed).
55 // Configs below are used for all Components when rendered by AnchorLayout.
56 <div id="cfg-Ext.BoxComponent-anchor"></div>/**
57 * @cfg {String} anchor <p><b>Note</b>: this config is only used when this Component is rendered

59 * based layout manager, for example:<div class="mdetail-params"><ul>
60 * <li>{@link Ext.form.FormPanel}</li>
61 * <li>specifying <code>layout: 'anchor' // or 'form', or 'absolute'</code></li>
63 * <p>See {@link Ext.layout.AnchorLayout}.{@link Ext.layout.AnchorLayout#anchor anchor} also.</p>

66 <div id="cfg-Ext.BoxComponent-tabTip"></div>/**
67 * @cfg {String} tabTip
68 * <p><b>Note</b>: this config is only used when this BoxComponent is a child item of a TabPanel.</p>
69 * A string to be used as innerHTML (html tags are accepted) to show in a tooltip when mousing over
70 * the associated tab selector element. {@link Ext.QuickTips}.init()
71 * must be called in order for the tips to render.

95 * <p><div class="mdetail-params"><ul>
96 * <li>If there is only one value, it applies to all sides.</li>
97 * <li>If there are two values, the top and bottom borders are set to the first value and the

99 * <li>If there are three values, the top is set to the first value, the left and right are set
100 * to the second, and the bottom is set to the third.</li>
101 * <li>If there are four values, they apply to the top, right, bottom, and left, respectively.</li>

153 <div id="cfg-Ext.BoxComponent-autoHeight"></div>/**
154 * @cfg {Boolean} autoHeight
155 * <p>True to use height:'auto', false to use fixed height (or allow it to be managed by its parent

157 * <p><b>Note</b>: Although many components inherit this config option, not all will

160 * <p>If the <i>browser</i> is managing the height, be aware that resizes performed by the browser in response
161 * to changes within the structure of the Component cannot be detected. Therefore changes to the height might
162 * result in elements needing to be synchronized with the new height. Example:</p><pre><code>
163 var w = new Ext.Window({
168 title: 'Collapse Me',
173 beforecollapse: function() {
176 beforeexpand: function() {
179 collapse: function() {

194 * <p><b>Note</b>: Although many components inherit this config option, not all will

200 <div id='grid-container' style='margin-left:25%;width:50%'></div>
202 * A Panel rendered into that target element must listen for browser window resize in order to relay its

233 /* // private internal config
