The problem with getting the top container component. Extjs

When I click on a tree record, I try to set the values ​​of this record and set these values ​​in the form.
In the eventcler itemclick: this.showDataFields function is triggered:
....
showDataFields: function(view, record, item, index, event) {
//got a form with fields
var panel = view.up('maintab');
console.log(panel)
//var formfield = panel.down('actionform');
//assign values from selected record to form fields
//formfield.loadRecord(record);
},
..........
In this function, view.up ('maintab') is underfined.
The maintab is Ext.tab.Panel which houses the tree.
Why can not get the topmost container and how to do it correctly?
Made an example in fiddle
thank

You should use view.up('treepanel').nextSibling().getForm().setValues(record.data) in your showDataFields function to set these values ​​in the form.

You could have provided a better example, therefore within the limitations that were proposed.
The answer I got was this were the changes in the ActionFormTree class that got the code below:
Ext.define('Fiddle.view.ActionFormTree', {
extend: 'Ext.form.Panel',
alias: 'widget.actionformtree',
xtype: 'actionform',//mainform,
initComponent: function(){
var me = this;
Ext.apply(me,{
items: [{
xtype: 'form',
border: false,
anchor: '100%',
height: 100,
layout: {
type: 'vbox',
align: 'middle',
pack: 'center'
},
items: [{
xtype: 'textfield',
name: 'text',
fieldLabel: 'Наименование',
itemId: 'name_field',
}, {
xtype: 'textfield',
name: 'code',
fieldLabel: 'Код',
itemId: 'code_field',
}]
}],
buttons: [{
text: 'Save Changes',
scope: me,
handler: function (button) {
//Эта панель со значениями полей
form = me.down('form');
var mainpanel = me.up('#maincontainer');
var treeform = mainpanel.down('usertree');
var sel = treeform.getSelectionModel().getSelection()[0];
store = treeform.getStore();
console.log(treeform)
store.suspendAutoSync()
var child = sel.set({
text: 'Измененное',
leaf: true
});
sel.expand()
store.resumeAutoSync();
//var currRecord = form.getRecord();
//if (currRecord) {
// form.updateRecord();
// form.reset();
//}
}
}]
});
me.callParent(arguments);
}
});
So, in this example, for it to work, you will need to have a node selected to work.
Hope it helps and finalize your question.

How to scroll to the end of the form in ExtJS

I have a form with autoScroll feature. How can I scroll to the bottom of the form when I add a new item to it?
height: 200,
autoScroll: true,
Here is my sample code

If the field is added at the end of the form then the following solution might help:
EXTJS 5 & 6
http://docs.sencha.com/extjs/5.1.0/api/Ext.form.Panel.html#cfg-scrollable
In the form config:
scrollable: true,
In button handler:
{
xtype: 'button',
itemId: 'addChildBtn',
disabled: false,
text: 'Clone fieldset',
handler: function () {
// Clone field set
var set = Ext.getCmp('s1');
var s = set.cloneConfig();
form.add(s);
this.up('form').getScrollable().scrollTo(0, 9999);
}
}
EXTJS 4
http://docs.sencha.com/extjs/4.1.3/#!/api/Ext.form.Panel-method-scrollBy
In button handler:
{
xtype: 'button',
itemId: 'addChildBtn',
disabled: false,
text: 'Clone fieldset',
handler: function () {
// Clone field set
var set = Ext.getCmp('s1');
var s = set.cloneConfig();
form.add(s);
this.up('form').scrollBy(0, 9999, true);
}
}

How to add links to modal window in ExtJs

I am trying to create a list of links from a data store, and then use an XTemplate to loop through and display all the links in the data store. I am trying to display the links in a modal window. This is my code:
var win;
var tpl = new Ext.XTemplate("<p>Field1: {f1}, Field2: {f2} </p>").compile();
var data = {
f1: 'a',
f2: null
};
if(!win){
win = new Ext.Window({
el:'hello-win',
layout:'fit',
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'component',
autoEl: {
html: '<input type="text">'
},
listeners: {
render: function(_component) {
_component.getEl().on('keyup', function(e) {
//console.log(this);
console.log(this.dom.childNodes[0].value);
});
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data,
renderTo: Ext.get('hello-win')
}
]
});
}
win.show(this);
There are no errors in console, but the links never load. It just shows my modal window and my textbox, but no links. I would put in in a jsfiddle, but I don't know how (I'm new to ExtJs).
How can I display a list of links in this modal window?

You should not define renderTo in you panel config. Component defined in items array will be rendered to parent component automatically.
Your window have two items so you can not use fit layout. This layout can be used only if component have only one child component. You can remove layout definition and Ext JS framework will use auto layout or you can use some layout which support more child items, like hbox, vbox, etc.
Your code should look like this:
var win = new Ext.Window({
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'textfield',
enableKeyEvents: true,
listeners: {
keyup: function(c) {
console.log(c.getValue());
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data
}
]
});
Also you should consider using textfield component instead of creating textfield by using component with autoEl config.

html with value from function

Im really new to this java script and Sencha touch so sorry if this question is simple but I didn't find a way to do this.
I have a function that returns a value .
now I want to display the value from the function inside an html line.
how im calling this function from html element? how I show the value?
config: {
title: 'Me',
iconCls: 'user',
//layout: 'fit',
/* create a title bar for the tab panel */
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Singers'
},
{
html: [
'<h1>Hi!! ' + this.setName +'</h1>'
].join("")
}
],
},
setName: function (val) {
var store =Ext.getStore('user');
var last = st.last('user');
return val=(last.get('user'));
}
});

You could use the itemId property to reference the component and then update its html property via the initialise listener.
For example:
config: {
title: 'Me',
iconCls: 'user',
//layout: 'fit',
/* create a title bar for the tab panel */
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Singers'
},
{
itemId:'htmlContainer', //use itemIds like div ids
xtype:'container',
html: ''
}
],
/**
* #cfg listeners
* Parent Component listeners go here.
* Check sencha touch doc for more information and other available events.
*/
listeners:{
initialize: 'onInitialise'
}
},
onInitialise: function()
{
//set the html config item here
var c = this.down('#htmlContainer');
c.setHtml(this.setName());
},
setName: function (val) {
....
}

ExtJS GridPanel width

I'm using Ext JS 2.3.0 and have created the search dialog shown below.
The search results are shown in a GridPanel with a single Name column, but notice that this column does not stretch to fill all the available horizontal space. However, after I perform a search, the column resizes properly (even if no results are returned):
How can I make the column display correctly when it's shown initially? The relevant code is shown below:
FV.FindEntityDialog = Ext.extend(Ext.util.Observable, {
constructor: function() {
var queryTextField = new Ext.form.TextField({
hideLabel: true,
width: 275,
colspan: 2,
});
var self = this;
// the search query panel
var entitySearchForm = new Ext.form.FormPanel({
width: '100%',
frame: true,
layout:'table',
layoutConfig: {columns: 3},
items: [
queryTextField,
{
xtype: 'button',
text: locale["dialogSearch.button.search"],
handler: function() {
var queryString = queryTextField.getValue();
self._doSearch(queryString);
}
}
]
});
// the search results model and view
this._searchResultsStore = new Ext.data.SimpleStore({
data: [],
fields: ['name']
});
var colModel = new Ext.grid.ColumnModel([
{
id: 'name',
header: locale['dialogSearch.column.name'],
sortable: true,
dataIndex: 'name'
}
]);
var selectionModel = new Ext.grid.RowSelectionModel({singleSelect: false});
this._searchResultsPanel = new Ext.grid.GridPanel({
title: locale['dialogSearch.results.name'],
height: 400,
stripeRows: true,
autoWidth: true,
autoExpandColumn: 'name',
store: this._searchResultsStore,
colModel: colModel,
selModel: selectionModel,
hidden: false,
buttonAlign: 'center',
buttons: [
{
text: locale["dialogSearch.button.add"],
handler: function () {
entitySearchWindow.close();
}
},
{
text: locale["dialogSearch.button.cancel"],
handler: function () {
entitySearchWindow.close();
}
}
]
});
// a modal window that contains both the search query and results panels
var entitySearchWindow = new Ext.Window({
closable: true,
resizable: false,
draggable: true,
modal: true,
viewConfig: {
forceFit: true
},
title: locale['dialogSearch.title'],
items: [entitySearchForm, this._searchResultsPanel]
});
entitySearchWindow.show();
},
/**
* Search for an entity that matches the query and update the results panel with a list of matches
* #param queryString
*/
_doSearch: function(queryString) {
def dummyResults = [['foo'], ['bar'], ['baz']];
self._searchResultsStore.loadData(dummyResults, false);
}
});

It's the same issue you had in an earlier question, the viewConfig is an config item for the grid panel check the docs , so it should be
this._searchResultsPanel = new Ext.grid.GridPanel({
viewConfig: {
forceFit: true
},
....other configs you need,
To be more precise the viewConfig accepts the Ext.grid.GridView configs, feel free to read the docs on that one too.
Otherwise this seems to be the only problem, and i refer the column width, not the gridpanel width. On the gridpanel you have a title and two buttons who doesn't seem to be affected. So i repeat the gridPanel's width is ok, it's the columns width issue.

Try to remove autoWidth from GridPanel configuration, because setting autoWidth:true means that the browser will manage width based on the element's contents, and that Ext will not manage it at all.
In addition you can try to call .doLayout(false, true) on your grid after it was rendered.

Try to add flex: 1 to your GridPanel
