/**
|
* This is a layout that inherits the anchoring of {@link Ext.layout.container.Anchor} and adds the
|
* ability for x/y positioning using the standard x and y component config options.
|
*
|
* This class is intended to be extended or created via the {@link Ext.container.Container#layout layout}
|
* configuration property. See {@link Ext.container.Container#layout} for additional details.
|
*
|
* @example
|
* Ext.create('Ext.form.Panel', {
|
* title: 'Absolute Layout',
|
* width: 300,
|
* height: 275,
|
* layout: {
|
* type: 'absolute'
|
* // layout-specific configs go here
|
* //itemCls: 'x-abs-layout-item',
|
* },
|
* url:'save-form.php',
|
* defaultType: 'textfield',
|
* items: [{
|
* x: 10,
|
* y: 10,
|
* xtype:'label',
|
* text: 'Send To:'
|
* },{
|
* x: 80,
|
* y: 10,
|
* name: 'to',
|
* anchor:'90%' // anchor width by percentage
|
* },{
|
* x: 10,
|
* y: 40,
|
* xtype:'label',
|
* text: 'Subject:'
|
* },{
|
* x: 80,
|
* y: 40,
|
* name: 'subject',
|
* anchor: '90%' // anchor width by percentage
|
* },{
|
* x:0,
|
* y: 80,
|
* xtype: 'textareafield',
|
* name: 'msg',
|
* anchor: '100% 100%' // anchor width and height
