How to overide extJS grid filter

I am creating a new project in that I am using Grid.
Here is my grid.
Ext.define('myProj.view.base.grid.myGrid', {
extend: 'Ext.grid.Panel',
alias: 'widget.myGrid',
controller: 'myProj-controller-base-grid-myGridcontroller',
requires: [
"myProj.controller.base.grid.myGridcontroller",
'Ext.grid.feature.Grouping',
'Ext.grid.plugin.BufferedRenderer',
'Ext.grid.filters.Filters',
],
mixins: ['Deft.mixin.Injectable'],
inject: ["gridStore"],
config: {
gridStore: null,
},
emptyText : "No data available",
plugins: {
gridfilters: true
},
overflowY: 'auto',
width:'100%',
stripeRows: false,
columnLines: false,
selModel: {
selType: 'checkboxmodel',
mode: 'SINGLE',
allowDeselect: true
},
initComponent: function () {
let _this=this;
Ext.apply(this, {
store: this.getListGridStore(),
});
this.callParent(arguments);
}
});
Now I want to overideto my filter. I have writtent my override code I am looking many examples but I am not geeting how to connect these two codes. ANy help will be usefull.
The overide code which I wanted to place here look like this.
Ext.override(Ext.grid.filters.filter.List, {
createMenuItems: function (store) {
debugger;
}
});

I believe the override works but the createMenuItems function is not called.
Did you define the filter for each column? Like in the code example shown here.
{
dataIndex: 'rating',
text: 'Rating',
width: 75,
filter: {
type: 'list',
value: 5
}
}

how can i close the view parent from view child?

I m using the template admin-dashbord from the ext framework 6.2.0.
When i use this, in my AuthenticationController
this.getView().destroy();
only the child view login close.Not the parent.
The app-main component is build behind the parent view.
I don't know how to close the parent view.
I have this following structure :
LoginWindow.js
Ext.define('Admin.view.authentication.LockingWindow', {
extend: 'Ext.window.Window',
xtype: 'lockingwindow',
requires: [
'Admin.view.authentication.AuthenticationController',
'Ext.layout.container.VBox'
],
cls: 'auth-locked-window',
closable: false,
resizable: false,
autoShow: true,
titleAlign: 'center',
maximized: true,
modal: true,
....
});
Login.js
Ext.define('Admin.view.authentication.Login', {
extend: 'Admin.view.authentication.LockingWindow',
xtype: 'login',
requires: [
'Admin.view.authentication.Dialog',
'Ext.container.Container',
'Ext.form.field.Text',
'Ext.form.field.Checkbox',
'Ext.button.Button'
],
title: 'Let\'s Log In',
defaultFocus: 'authdialog', // Focus the Auth Form to force field focus as well
....
{
xtype: 'button',
reference: 'loginButton',
scale: 'large',
ui: 'soft-green',
iconAlign: 'right',
iconCls: 'x-fa fa-angle-right',
text: 'Login',
formBind: true,
listeners: {
click: 'onLoginButton'
}
},
});
AuthenticationController.js
Ext.define('Admin.view.authentication.AuthenticationController', {
extend: 'Ext.app.ViewController',
alias: 'controller.authentication',
onLoginButton: function() {
var me = this;
localStorage.setItem("TutorialLoggedIn", true);
// Remove Login Window
this.getView().destroy();
// Add the main view to the viewport
var main = Ext.create({
xtype: 'app-main'
});
me.redirectTo('dashboard', true);
},
});

Get the view :login
Get the parent :LockingWindow
destroy the parent: LockingWindow
here is my method added to AuthenticationController.js and called in onLoginButton() method.
createInterface : function(){
var me = this,
view = me.getView(),
window = view.up('window');
Ext.create({
xtype: 'app-main'
});
window.destroy();
me.redirectTo('dashboard', true);
}

I have a component define by itemid how I can get it in controller

i m new in sencha . i always use id to define my component . but now i want to change it to itemid . and i found the Ext.getcmp('id'), is not work . and when i use Ext.componentquery.query('itemid') ,the console in chrome said Ext.componentquery is not a function. what can i do?
my view code:
Ext.define('ylp2p.view.Main', {
extend: 'Ext.tab.Panel',
xtype: 'main',
requires: [
'Ext.TitleBar',
'Ext.carousel.Carousel',
'ylp2p.store.datainterests',
'Ext.Label',
'Ext.List'
],
config: {
fullscreen: true,
tabBarPosition: 'bottom',
scrollable: 'vertical',
items: [
{
title: '首页',
iconCls: 'home',
styleHtmlContent: true,
//true to automatically style the HTML inside the content target of this component (body for panels).
scrollable: true,
layout: 'card',
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'ylp2p'
},
{
xtype: 'container',
layout: 'vbox',
items:[
{
xtype: 'label',
itemId: 'datalabel',---------this component is what i want
height: 50,
store: 'datainterests',
tpl: '金额：{data},利息：{earn}',
}//end label
]
}
]//end items
}
]
},//end config
//end listeners
});
my controller code :
Ext.define('ylp2p.controller.viewdata',{
extend: 'Ext.app.Controller',
launch: function(){
console.log('hello ! here is controller launch function');
var storeId = Ext.create('ylp2p.store.datainterests');
storeId.load({
callback: function(records, operation, success){
Ext.each(records, function(record) {
Ext.ComponentQuery.query("main > datalabel").setData({----it cant work . why?
data : record.get('data'),
earn : record.get('earn')
});
});
}
});
}
});
the console error said:
Uncaught TypeError: Ext.ComponentQuery.query(...).setData is not a function

i got it
var label = Ext.ComponentQuery.query('main #datalabel')[0];
label.setData({
data : record.get('data'),
earn : record.get('earn')
});

I found Sencha's own code to use menu.down('#groupMenuItem') to access itemId:'groupMenuItem'. So you should be fine using:
Ext.ComponentQuery.query('#itemid')

Use this.
var label = Ext.ComponentQuery.query('main #datalabel'); -- check on console label should not undefined
label.tpl.updateData -- you will find methods with tpl

ExtJs DataView height inside a vbox

I've got a profile home view (Home2). In this view a want to show a top docked title bar, a user profile info and user's posts.
Ext.define('FreescribbleApp.view.Home2', {
extend: 'Ext.Panel',
xtype: 'homepage2',
config: {
title: 'Home',
iconCls: 'home',
styleHtmlContent: true,
scrollable: true,
items:[
{
xtype: 'titlebarview'
},
{
xtype: 'userinfoview',
itemId: 'userInfoWrapper',
height: 150
},
{
itemId: 'homeStage',
autoScroll: true
}
]
}
});
I also have a DataView:
Ext.define('FreescribbleApp.view.PostList', {
extend: 'Ext.dataview.DataView',
xtype: 'postlist',
config: {
scrollable: false,
defaultType: 'postitem',
useComponents: true
}
});
which lists DataItems:
Ext.define('FreescribbleApp.view.PostItem', {
extend: 'Ext.dataview.component.DataItem',
xtype: 'postitem',
requires: ['Ext.field.Text'],
config: {
style: 'background-color: #f00',
height: 100,
styleHtmlContent: false,
authorName: {
height: 30,
style: 'background-color: #0f0'
},
dataMap: {
getAuthorName: {
setHtml: 'userName'
}
},
},
applyAuthorName: function(config) {
return Ext.factory(config, Ext.Component, this.getAuthorName());
},
updateAuthorName: function(newAuthorName, oldAuthorName) {
if (newAuthorName) {
this.add(newAuthorName);
}
if (oldAuthorName) {
this.remove(oldAuthorName);
}
}
});
in my HomeController I create a PostStore, fill it with some posts and add to the DataView. After that I add the DataView to my Home2-View Element HomeStage:
var postStore = Ext.create('FreescribbleApp.store.PostStore', {
params: {
user: localStorage.getItem('userId'),
token: localStorage.getItem('token'),
target: localStorage.getItem('userName')
}
});
postStore.load();
postStore.on('load', function(){
var currentView = Ext.create('FreescribbleApp.view.PostList');
currentView.setStore(postStore);
homeStage.add(currentView);
});
I can't see any items till I set height of the DataView. It is a common issue, bun in my case I cannot set my HomeStage to 'fit' since it's only a part of Home2 and the item userinfo should get scrolled with the posts. So how can I set size of my DataView dynamicly?
I also see in my Sencha debuger for Chrome that between my DataView-List and my DataItems is a Container, which has the right heigh of all the items inside. can I just get the size of this container and set i for my DataView? Will it work and will it be a good practice?

I'm sorry, i just had to set scrollable: null, and not false in my DataView!

Sencha Touch List Component Inside Tabbed Toolbar

I am working with the Sencha touch framework and there list item component. I have only been working with this for about 2 weeks now and I can not figure out how to get the "onItemDisclosure" to open up the "detailPanel". I am trying to follow this example: http://vimeo.com/19245335. I have pasted my code below. Any help is very much appreciated.
GoW3Guide.views.detailPanel = Ext.extend(Ext.Panel, {
id: 'detailpanel',
tpl: 'Hello, {firstName}!',
dockedItems: [
{
xtype: 'toolbar',
items: [{
text: 'back',
ui: 'back',
handler: function() {
GoW3Guide.Viewport.setActiveItem('disclosurelist', {type:'slide', direction:'right'});
}
}]
}
]
});
Ext.reg('detailPanel', GoW3Guide.views.detailPanel);
GoW3Guide.views.listPanel = Ext.extend(Ext.List, {
id: 'disclosurelist',
store: GoW3Guide.ListStore,
itemTpl: '<div class="contact">{firstName} {lastName}</div>',
grouped: true,
onItemDisclosure: function(record, btn, index) {
GoW3Guide.views.detailPanel.update(record.data);
GoW3Guide.views.Guidescard.setActiveItem('detailpanel');
}
});
Ext.reg('listPanel', GoW3Guide.views.listPanel);
GoW3Guide.views.Guidescard = Ext.extend(Ext.Panel, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'slide',
initComponent: function() {
Ext.apply(this, {
items: [GoW3Guide.views.listPanel, GoW3Guide.views.detailPanel]
});
GoW3Guide.views.Guidescard.superclass.initComponent.apply(this, arguments);
}
});
Ext.reg('guidescard', GoW3Guide.views.Guidescard);

Are you getting any javascript errors?
According to the docs setActiveItem either needs a component instance, a number (card index), or a config object, e.g. {xtype:'detailPanel'}
If you want to make a new detail panel active try
GoW3Guide.views.Guidescard.setActiveItem({xtype:'detailpanel'});
or
GoW3Guide.views.Guidescard.setActiveItem(new GoW3Guide.views.detailPanel());
