Extjs4布局layout

来源:互联网 发布:苹果下歌用什么软件 编辑:程序博客网 时间:2024/05/24 05:49
1)Ext.layout.container.Border 
    layout : 'border'表示我们使用了Border布局,这种布局方式称为边界布局,它将页面分隔成为:west,east,south,north,center这五个部分,我们在items里面使用region参数为它组织定义具体的位置。
    north和south部分只能设置高度(height),west和east部分只能设置宽度(width)。northsouth west east区域变大了,center区域就变小了。
    参数 split:true 可以拖动除了center四个区域的大小。
    参数 collapsible:true激活折叠功能,前面title必须设置,因为折叠按钮是出现标题部分
注意:center区域是必须使用的,而且center 区域不允许折叠。
Ext.create('Ext.panel.Panel',{
           width:500,
            height: 400,
             layout: 'border',
            items: [{
                title: 'South Region isresizable',
                region: 'south'    //position for region
                xtype: 'panel',
                height: 100,
                split: true        //enable resizing
                margins: '0 5 5 5'
            },{
                 //xtype: 'panel' implied by default
                title: 'West Region iscollapsible',
                region:'west',
                xtype: 'panel',
                margins: '5 0 0 5',
                width: 200,
                collapsible: true  //make collapsible
                id: 'west-region-container',
                layout: 'fit'
            },{
                title: 'Center Region',
                region: 'east'    //center region is required, no width/heightspecified
                xtype: 'panel',
                layout: 'fit',
                margins: '5 5 0 0'
            }],
            renderTo: Ext.getBody()
        });

2)Ext.layout.container.Fit
    layout:'fit'表示我们引用了fit布局。当客户要求一个窗口里显示一个Grid表格,可以让它自动适应窗体的大小的变化,窗体变大时候Grid表格也变大,窗体变小的时候也变小。
注意:layout :'fit'组件的items只能放一个组件,如果放了多个组件,那么也只有一个子组件会起作用。
Ext.define('ParentWindow',{
                extend: 'Ext.window.Window',
                title: 'ParentWindow',
                width: '300px',
                height: '200px',
                layout: 'fit',
                items: {
                     xtype: 'gridpanel',
                     store:store,
                  stateful: true,
                  layout : 'fit',
                  columns: [
                      {
                          text    : 'Company',
                          flex    : 1,
                          sortable : false,
                          dataIndex: 'company'
                      },
                      {
                          text    : 'Price',
                          width    :75,
                          sortable : true,
                          renderer : 'usMoney',
                          dataIndex: 'price'
                      },
                      {
                          text    : 'Change',
                          width    :75,
                          sortable : true,
                          dataIndex: 'change'
                      },
                      {
                          text    : '% Change',
                          width    :75,
                          sortable : true,
                          
                          dataIndex: 'pctChange'
                      },
                      {
                          text    : 'Last Updated',
                          width    :85,
                          sortable : true,
                          renderer : Ext.util.Format.dateRenderer('m/d/Y'),
                          dataIndex: 'lastChange'
                      }]
                }
           });


3)Ext.layout.container.Accordion
     layout: 'accordion'代表使用了accordion布局方式。
var accrodion= Ext.create('Ext.panel.Panel',{
              
               layout:'accordion',
              defaults: {
                  bodyStyle: 'padding:15px'
              },
              layoutConfig: {
                  titleCollapse: true,
                  animate: true,
                  activeOnTop: false
              },
              items: [{
                  title: 'Panel 1',
                  html: 'Panel content!'
              },{
                  title: 'Panel 2',
                  html: 'Panel content!'
              },{
                  title: 'Panel 3',
                  html: 'Panel content!'
              }],
              

           });


4)Ext.layout.container.Card
    layout : 'card'Card布局可以看做是一叠卡片,从上面看起来就像是一张卡片,我们可以把中间的卡片抽出来,放到最上面,可是每次只能显示一张卡片。
<</span>script type="text/javascript">
     var navigate= function(panel,direction){
           var layout= panel.getLayout();
           layout[direction]();
          Ext.getCmp('move-prev').setDisabled(!layout.getPrev());
          Ext.getCmp('move-next').setDisabled(!layout.getNext());
     }
     var cardPanel= Ext.create('Ext.panel.Panel',{
         layout: 'card',
        activeItem:0, // make sure the active item is set on thecontainer config!
        bodyStyle: 'padding:15px',
        defaults: {
             //applied to each contained panel
            border: false
        },
           bbar: [{
                     id:'move-prev',
                     text: '上一章',
                     xtype: 'button',
                     listeners :{
                         'click' : function(btn){
                   navigate(btn.up('panel'),'prev');
                         }
                           }
                     
                  },{
                     id:'move-next',
                     text: '下一章',
                     xtype: 'button',
                     listeners :{
                         'click' : function(btn){
                   navigate(btn.up('panel'),'next');
                         }
                           }
                  }],
           items: [
                   {
                      id: 'card0',
                      html: '

Welcometo card0!

第一章:好好学习'
                   },{
                      id: 'card1',
                      html: '

Welcometo card1!

第二章:天天向上'
                   },{
                      id: 'card2',
                      html: '

Welcometo card2!

第三章:good good study'
                   },{
                      id: 'card3',
                      html: '

Welcometo card3!

第四章:天天'
                   },{
                      id: 'card4',
                      html: '

Welcometo card4!

第五章:顶顶顶'
                   }
                   ]
     });
     Ext.onReady(function(){
           Ext.create('Ext.window.Window',{
                title: 'CardLayoutWindow',
                width: '300px',
                height: '200px',
                layout: 'fit',
                items: cardPanel
           }).show();
     });
</</span>script>

5)Ext.layout.container.Anchor
   layout:'anchor'设置为anchor布局模式。在每一个panel中的items中有一个参数anchor,参数是一个字符串。
    anchor: '75%20%',中间用一个空格隔开,空格前后是%的数字。第一个参数75%:意思是宽度设置为整体的75%;第二个参数20%:是设置高度为整体的20%。
    anchor:'-300 -200',中间用一个空格隔开,空格前后是整数,第一个参数-300:表示距离右侧的相对距离;第二个参数-200:表示距离底部的相对距离。
    <</span>script type="text/javascript">
     Ext.onReady(function(){
           Ext.create('Ext.Panel',{
              width: 500,
              height: 400,
              title: "AnchorLayout Panel",
               layout: 'anchor',
              renderTo: Ext.getBody(),
              items: [{
                  xtype: 'panel',
                  title: '75%宽度 20%高度',
                  anchor: '75% 20%'
              },{
                  xtype: 'panel',
                  title: 'Offset -300 Width & -200Height',
                  anchor: '-300 -200'    
              },{
                  xtype: 'panel',
                  title: 'Mixed Offset andPercent',
                  anchor: '-250 20%'
              }]
           });
     });
</</span>script>



6)Ext.layout.container.Absolute
    layout:'absolute'。我们可以对每一个控件的位置进行控制。
    x:设置x坐标;y:设置y坐标
    var alayout= Ext.create('Ext.form.Panel',{
        width: 300,
        height: 275,
         layout:'absolute',
       
        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
        }]
        
     });


7)Ext.layout.container.Column
   layout:'column':表格布局。
    注意items中 columnWidth的数值必须是0~1之间的小数,它表示每个子组件在整体中所占的百分比。它们的总和应该是1,否则会出现没有填满的情况。
    var columnLayout= Ext.create('Ext.panel.Panel',{
        width: 350,
        height: 250,
         layout:'column',
        items: [{
            title: '表格Layout 1',
            columnWidth: .25
        },{
            title: '表格Layout 2',
            columnWidth: .55
        },{
            title: '表格Layout 3',
            columnWidth: .20
        }],
        renderTo: Ext.getBody()
    });


8)Ext.layout.container.Table
    layout : 'table'表格布局。table布局把页面定义成一个表格包括行和列。它在生成代码的时候就是生成了html代码中的标签。
         var tableLayout= Ext.create('Ext.panel.Panel',{
                width:300,
            height: 150,
                layout: {
                     type: 'table',
                     columns: 3
                },
                defaults:{
                 //applied to each contained panel
                bodyStyle:'padding:20px'
            },
                items:[{
                html: 'A table',
                rowspan: 2
            },{
                html: 'B table',
                colspan: 2
            },{
                html: 'C table',
                cellCls: 'highlight'
            },{
                html: 'D table'
            }]

           });

<<span>tbody>
<<span>tr>
<<span>td id="" class="x-table-layout-cell " colspan="1" rowspan="2">
