extjs 5网格的滚动条在边界布局面板中不起作用

问题描述

在边界布局面板中，即使网格的存储时间足以使网格溢出，网格的滚动条也无法正常工作！

如果我的网格在没有边框的布局面板中，滚动条是可以的，但是当我把网格放在边框布局面板中时，要么没有滚动条，要么是无效的滚动条！

  {
 //我想要的是让这个网格滚动！滚动条嵌套在边框布局面板中。 
 xtype：'grid'，
 title：'west bottom grid（我要求你的滚动条！）'，
列：[{
 text：'header'，
 dataIndex：'header'
}]，
 store：Ext.create（'MyApp.OverflowStore'），//这个存储足够长以使网格溢出
 autoScroll：真正的
} 
  

完整的代码：参见sencha fiddle：

如果有人可以帮助给网格一个正确的滚动条？

容器以及确保像网格这样的容器具有弹性值以便正确分配空间。

in border layout panel , the grid's scroll-bar doesn't work correctly even though the store of grid is long enough to make the grid overflow!

if my grid is in none border layout panel , the scroll-bar is OK, but when i put the grid in the border layout panel , either there is no scroll-bar ,either there is a invalid scroll-bar!

{
        // what i want is  to make this grid to scroll ! the scroll-bar is nested in a border layout panel.
        xtype: 'grid',
        title: 'west bottom grid(I am begging for your scrollbar !)',
        columns: [{
            text: 'header',
            dataIndex: 'header'
        }],
        store: Ext.create('MyApp.OverflowStore'), //this store is long enough to make the grid overflow
        autoScroll: true
    }

full code : see sencha fiddle : https://fiddle.sencha.com/#fiddle/ffv

if anyone could help to give the grid a correct scrollbar ?

解决方案

You should make sure you set up layouts for your components' containers as well as to make sure that containers like the grid have a flex value to have the space properly allocated.See corrected fiddle here
