для вашего основного контейнера, я предлагаю макеты hbox и / или vbox.эти макеты - это то, что вы ищете.вот пример:
var testPanel = new Ext.Viewport( {
id : 'vp_test',
layout : 'hbox',
align : 'stretch',
items : [
{
id : 'pnl_child_1',
title : 'Test 1',
flex : 2
},
{
id : 'pnl_child_2',
title : 'Test 2',
flex : 3,
layout : 'vbox',
align : 'stretch',
items : [
{
id : 'pnl_child_3',
title : 'Test 3',
flex : 1
},
{
id : 'pnl_child_4',
title : 'Test 4',
flex : 1
}
]
},
]
} );
вы можете обратиться к документации, viewport , hbox , vbox
itemRts = {
xtype: 'panel',
title: 'Route',
// region: 'north', <<< we don't need this anymore
flex: 1, // this means that this container has 1 flexible share
// autoHeight: true, <<< this will ruin all layout
layout: 'form',
// width: 294, <<< we don't need this anymore
bodyStyle: 'padding:10px 12px 10px',
id: 'ROUTE_PANEL',
el:'Route_Setup',
items: [
{
xtype:'button',
text:'Go',
anchor:'0',
id:'GO_BTN'
}
]
};
itemEvts = {
xtype: 'panel',
title: 'Events',
// region: 'center', <<< we don't need this anymore
flex: 1, // this means that this container has 1 flexible share
layout: 'column',
tpl: 'Please put events here.', // <<<< if you're not going to use xTemplates you should use html property instead
//bodyStyle: 'padding:10px 12px 10px',
border: false,
hideBorders: true,
id: 'EVENT_PANEL',
el : 'Event_Legend',
autoScroll: true
};
newView = new Ext.Viewport({
//// if you have only one child component you can use fit layout for viewport.
//// and consider removing that only child. use viewport as main container.
layout : "border",
items: [
{
xtype: 'panel',
margins: '10 0 10 10',
region: 'center',
// width: 200, <<<< width has no effect on center region
/// we'll use hbox with align stretch
layout: 'hbox',
align: 'stretch',
// split: true, <<<< split has no effect on center region
