Base class for any {@link Ext.Component Component} that is to be sized as a box, using width and height.
- *BoxComponent provides automatic box model adjustments for sizing and positioning and will work correctly - * within the Component rendering model.
- *A BoxComponent may be created as a custom Component which encapsulates any HTML element, either a pre-existing - * element, or one that is created to your specifications at render time. Usually, to participate in layouts, - * a Component will need to be a BoxComponent in order to have its width and height managed.
- *To use a pre-existing element as a BoxComponent, configure it so that you preset the el property to the - * element to reference:
-var pageHeader = new Ext.BoxComponent({
- el: 'my-header-div'
-});To create a BoxComponent based around a HTML element to be created at render time, use the - * {@link Ext.Component#autoEl autoEl} config option which takes the form of a - * {@link Ext.DomHelper DomHelper} specification:
-var myImage = new Ext.BoxComponent({
- autoEl: {
- tag: 'img',
- src: '/images/my-image.jpg'
- }
-});Note: this config is only used when this BoxComponent is rendered - * by a Container which has been configured to use the {@link Ext.layout.BorderLayout BorderLayout} - * layout manager (e.g. specifying layout:'border').
See {@link Ext.layout.BorderLayout} also.
- */ - // margins config is used when a BoxComponent is rendered by BorderLayout or BoxLayout. - /** - * @cfg {Object} marginsNote: this config is only used when this BoxComponent is rendered - * by a Container which has been configured to use the {@link Ext.layout.BorderLayout BorderLayout} - * or one of the two {@link Ext.layout.BoxLayout BoxLayout} subclasses.
- *An object containing margins to apply to this BoxComponent in the - * format:
-{
- top: (top margin),
- right: (right margin),
- bottom: (bottom margin),
- left: (left margin)
-}May also be a string containing space-separated, numeric margin values. The order of the - * sides associated with each value matches the way CSS processes margin values:
- *Defaults to:
- * {top:0, right:0, bottom:0, left:0}
- * True to use height:'auto', false to use fixed height (or allow it to be managed by its parent - * Container's {@link Ext.Container#layout layout manager}. Defaults to false.
- *Note: Although many components inherit this config option, not all will - * function as expected with a height of 'auto'. Setting autoHeight:true means that the - * browser will manage height based on the element's contents, and that Ext will not manage it at all.
- *If the browser is managing the height, be aware that resizes performed by the browser in response - * to changes within the structure of the Component cannot be detected. Therefore changes to the height might - * result in elements needing to be synchronized with the new height. Example:
-var w = new Ext.Window({
- title: 'Window',
- width: 600,
- autoHeight: true,
- items: {
- title: 'Collapse Me',
- height: 400,
- collapsible: true,
- border: false,
- listeners: {
- beforecollapse: function() {
- w.el.shadow.hide();
- },
- beforeexpand: function() {
- w.el.shadow.hide();
- },
- collapse: function() {
- w.syncShadow();
- },
- expand: function() {
- w.syncShadow();
- }
- }
- }
-}).show();
-True to use width:'auto', false to use fixed width (or allow it to be managed by its parent - * Container's {@link Ext.Container#layout layout manager}. Defaults to false.
- *Note: Although many components inherit this config option, not all will - * function as expected with a width of 'auto'. Setting autoWidth:true means that the - * browser will manage width based on the element's contents, and that Ext will not manage it at all.
- *If the browser is managing the width, be aware that resizes performed by the browser in response - * to changes within the structure of the Component cannot be detected. Therefore changes to the width might - * result in elements needing to be synchronized with the new width. For example, where the target element is:
-<div id='grid-container' style='margin-left:25%;width:50%'></div>
-
-var myPanel = new Ext.Panel({
- renderTo: 'grid-container',
- monitorResize: true, // relay on browser resize
- title: 'Panel',
- height: 400,
- autoWidth: true,
- layout: 'hbox',
- layoutConfig: {
- align: 'stretch'
- },
- defaults: {
- flex: 1
- },
- items: [{
- title: 'Box 1',
- }, {
- title: 'Box 2'
- }, {
- title: 'Box 3'
- }],
-});
-{width:10, height:20}.
- * @param {Mixed} width The new width to set. This may be one of:{width: widthValue, height: heightValue}.undefined to leave the width unchanged.undefined to leave the height unchanged.Returns the outermost Element of this Component which defines the Components overall size.
- *Usually this will return the same Element as {@link #getEl},
- * but in some cases, a Component may have some more wrapping Elements around its main
- * active Element.
An example is a ComboBox. It is encased in a wrapping Element which
- * contains both the <input> Element (which is what would be returned
- * by its {@link #getEl} method, and the trigger button Element.
- * This Element is returned as the resizeEl.
