在我的小程序中,我正在尝试为嵌套列表的每个叶节点设置自定义容器。
以下是我试图测试的几个任意示例容器:
Ext.define('DetailContainer1', {
extend: 'Ext.Container',
xtype: 'detail-container1',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #a9a9a9;',
// flex: 1,
items: [{
html: 'Detail Container1'
}]
});
Ext.define('DetailContainer2', {
extend: 'Ext.Container',
xtype: 'detail-container2',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #c9c9c9;',
// flex: 1,
items: [{
html: 'Detail Container2',
flex: 1
}, {
xtype: 'button',
text: 'Hit me!',
flex: 1
}]
});
当用户点击叶节点时,如何切换新容器?
此操作应在onLeafItemTap()
中执行。顺便说一下,初始容器(#2)目前没有显示。这是布局问题吗?
以下是关于屏幕应该是什么样子的一些想法:

Ext.Loader.setConfig({
enabled: true
});
Ext.define('DetailContainer1', {
extend: 'Ext.Container',
xtype: 'detail-container1',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #a9a9a9;',
// flex: 1,
items: [{
html: 'Detail Container1'
}]
});
Ext.define('DetailContainer2', {
extend: 'Ext.Container',
xtype: 'detail-container2',
layout: {
type: 'vbox'
},
height: 300,
style: 'background-color: #c9c9c9;',
// flex: 1,
items: [{
html: 'Detail Container2',
flex: 1
}, {
xtype: 'button',
text: 'Hit me!',
flex: 1
}]
});
Ext.define('ListItem', {
extend: 'Ext.data.Model',
config: {
fields: ['text']
}
});
Ext.define('Sencha.view.MainView', {
extend: 'Ext.Container',
xtype: 'mainview',
layout: {
type: 'hbox'
},
initialize: function() {
this.treeStore = Ext.create('Ext.data.TreeStore', {
model: 'ListItem',
defaultRootProperty: 'items',
root: {
items: [{
text: 'Containers',
items: [{
text: 'Detail #1',
leaf: true
}, {
text: 'Detail #2',
leaf: true
}]
}]
}
});
this.detailContainer = Ext.create("DetailContainer2", {});
this.nestedList = Ext.create('Ext.NestedList', {
docked: 'left',
width: 300,
flex: 1,
store: this.treeStore,
detailCard: true,
detailContainer: this.detailContainer,
listeners: {
scope: this,
leafitemtap: this.onLeafItemTap
}
});
this.setItems([this.detailContainer, this.nestedList]);
},
onLeafItemTap: function(nestedList, list, index, node, record, e) {
var detailCard = nestedList.getDetailCard();
// nestedList.setDetailContainer(Ext.create("DetailContainer1", {}))
// detailCard.setHtml(record.get('text') + "...");
}
});
Ext.application({
launch: function() {
var container = Ext.create("Ext.Container", {
layout: {
type: 'hbox'
},
items: [{
xtype: 'mainview'
}]
});
Ext.Viewport.add(container);
}
});

最后,我找到了解决问题的正确方法。
一些解释:
hbox
的右侧显示“自定义detailContainer”,则很明显您应该为detailCard
禁用Ext.NestedList
配置,因为它旨在显示内嵌(即取代您的Ext.NestedList
)。Ext.define
时,所有内容都应包含在config
中(extend
,xtype
,alias
,id
除外,所以在此如果必须将layout
放入config
)。flex
也应在config
中定义。leafitemtap
事件中,只需更新您的detailContainer
配置并再次删除/添加,因为它不会动态更新。请查看下面的修改后的代码段,它对我来说非常适合。
Ext.Loader.setConfig({ enabled: true });
Ext.define('DetailContainer1', {
extend: 'Ext.Container',
xtype: 'detail-container1',
config: {
flex: 1,
layout: {
type: 'vbox'
},
style: 'background-color: #a9a9a9;',
items: [
{html: 'Detail Container1'}
]
}
});
Ext.define('DetailContainer2', {
extend: 'Ext.Container',
xtype: 'detail-container2',
config: {
flex: 1,
layout: {
type: 'vbox'
},
style: 'background-color: #c9c9c9;',
items: [
{html: 'Detail Container2', flex: 1},
{xtype: 'button', text: 'Hit me!', flex: 1}
]
}
});
Ext.define('ListItem', {
extend: 'Ext.data.Model',
config: {
fields: ['text']
}
});
Ext.define('Sencha.view.MainView', {
extend: 'Ext.Container',
xtype: 'mainview',
id: 'mainview',
config: {
layout: {
type: 'hbox'
},
},
initialize: function() {
this.treeStore = Ext.create('Ext.data.TreeStore', {
model: 'ListItem',
defaultRootProperty: 'items',
root: {
items: [
{
text: 'Containers',
items: [
{ text: 'Detail #1', leaf: true },
{ text: 'Detail #2', leaf: true }
]
}
]
}
});
this.detailContainer = Ext.create("DetailContainer2");
this.nestedList = Ext.create('Ext.NestedList', {
flex: 1,
store: this.treeStore,
listeners: {
scope: this,
leafitemtap: this.onLeafItemTap
}
});
this.setItems([this.nestedList, this.detailContainer]);
},
onLeafItemTap: function(nestedList, list, index, node, record, e) {
mainview = Ext.getCmp('mainview');
if (index==0) {
mainview.detailContainer = Ext.create("DetailContainer1");
} else {
mainview.detailContainer = Ext.create("DetailContainer2");
}
mainview.removeAt(1);
mainview.add(mainview.detailContainer);
}
});
Ext.application({
launch: function() {
Ext.Viewport.add(
Ext.create("Ext.Container", {
layout: {
type: 'card'
},
items: [
{ xtype : 'mainview'}
]
}));
}
});
