I want to collapse or expand a node based on a condition in tree.panel in extjs 4.2.1
tree.on("beforeitemexpand",function(node) {
if (booleanFlag === true) {
//allow to expand
} else {
//donot allow to expand
}
});
I have tried the beforeitemExpand then return false if booleanFlag is false, but it is not working.
The event "beforeitemexpand" appears to have a bug in Extjs 4.2.1, its not ideal but you could use "beforeitemclick" and "beforeitemdblclick" to achieve the functionality that you want:
Ext.application({
name: 'Fiddle',
launch: function () {
var enableHomeExpand = false;
var enableBookExpand = false;
var store = Ext.create('Ext.data.TreeStore', {
root: {
children: [{
text: 'homework',
expanded: false,
children: [{
text: 'book report',
children: [{
text: 'test',
leaf: true
}, {
text: 'test 2',
leaf: true
}]
}, {
text: 'algebra',
leaf: true
}]
}, {
text: 'homework',
children: [{
text: 'book report',
children: [{
text: 'test',
leaf: true
}, {
text: 'test 2',
leaf: true
}]
}]
}]
}
});
var handleClick = function (node,rec,item){
if ((rec.data.text =="book report")&&(enableBookExpand)){
return true;
}
if ((rec.data.text =="homework")&&(enableHomeExpand)){
return true;
}
return false;
}
var treepanel = Ext.create('Ext.tree.Panel', {
title: 'Simple Tree',
width: 400,
height: 200,
store: store,
rootVisible: false,
renderTo: Ext.getBody(),
listeners:{
beforeitemdblclick: handleClick,
beforeitemclick: handleClick
},
buttons:[{
text:'Enable Expand "homework"',
handler: function(){ enableHomeExpand = true; }
},
{
text:'Enable Expand "book report"',
handler: function(){ enableBookExpand = true; }
}]
});
}
});
Here is the FIDDLE
Using AppSDK 2.0, how can I see the "Release" field in the PortfolioItem/Feature when I create a store?
Release needs to be among the fetched fields in WsapiDataStore:
fetch: ['FormattedID','Name','UserStories','Release']
But then in a Rally.data.custom.Store, to account for Features that are not assigned to a release, this condition is used:
Release: (release && release.Name) || 'None'
Here is the code:
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function() {
Ext.create('Rally.data.WsapiDataStore', {
model: 'PortfolioItem/Feature',
fetch: ['FormattedID','Name','UserStories','Release'],
pageSize: 100,
autoLoad: true,
listeners: {
load: this._onDataLoaded,
scope: this
}
});
},
_createGrid: function(features) {
this.add({
xtype: 'rallygrid',
store: Ext.create('Rally.data.custom.Store', {
data: features,
pageSize: 100
}),
columnCfgs: [
{
text: 'Formatted ID', dataIndex: 'FormattedID', xtype: 'templatecolumn',
tpl: Ext.create('Rally.ui.renderer.template.FormattedIDTemplate')
},
{
text: 'Name', dataIndex: 'Name'
},
{
text: 'Release', dataIndex: 'Release'
},
{
text: 'Story Count', dataIndex: 'StoryCount'
},
{
text: 'User Stories', dataIndex: 'UserStories',
renderer: function(value) {
var html = [];
Ext.Array.each(value, function(userstory){
html.push('' + userstory.FormattedID + '')
});
return html.join(', ');
}
}
]
});
},
_onDataLoaded: function(store, data){
var features = [];
var pendingstories = data.length;
//debugger;
Ext.Array.each(data, function(feature) {
var release = feature.get('Release');
var f = {
FormattedID: feature.get('FormattedID'),
Name: feature.get('Name'),
Release: (release && release.Name) || 'None',
_ref: feature.get("_ref"),
StoryCount: feature.get('UserStories').Count,
UserStories: []
};
var stories = feature.getCollection('UserStories');
stories.load({
fetch: ['FormattedID'],
callback: function(records, operation, success){
Ext.Array.each(records, function(story){
var number = story.get('DirectChildrenCount');
if (number == 0) {
f.UserStories.push({_ref: story.get('_ref'),
FormattedID: story.get('FormattedID')
});}
}, this);
--pendingstories;
if (pendingstories === 0) {
this._createGrid(features);
}
},
scope: this
});
features.push(f);
}, this);
}
});
starting with the MVC demo project guide I added an extra actioncolumn and I was wondering how to wire it in the controller file ?
guide: http://www.sencha.com/learn/the-mvc-application-architecture/
Ext.define('app.view.admin.viewlist', {
extend: 'Ext.grid.Panel',
columnLines: true,
region: 'center',
menuDisabled: true,
layout: 'fit',
initComponent: function (cnfg) {
this.columns = [
{
text: 'date',
dataIndex: 'Series',
sortableColumns: false,
hideable: false,
enableLocking: false,
width: 100
},{
hidden : true,
text:'Values',
sortableColumns : false,
hideable: false,
columns:[{
header: 'D1',
hidden: true,
dataIndex: 'D10EOD',
sortableColumns : false,
hideable: false
},{
xtype: 'actioncolumn',
icon: '/static/img/icon/table_refresh.png',
tooltip: 'Reset',
align: 'center'
}]
}
];
this.callParent(arguments);
}});
Controller init function
init: function() {
this.control({
'volatilityedit actioncolumn img' : { <--- ??
click: this.reset
}
});
},
reset: function(grid, rowIndex, colIndex) {
//var rec = grid.getStore().getAt(rowIndex);
alert("Go");
},
Thanks
Depend on what your actions should do you can decide if you need controler or not.
You should use controller when your action interacts with other components - otherwise you can write own methods inside component (grid)
Here you have simple example of grid with actioncolumn:
Ext.onReady(function () {
Ext.create('Ext.data.Store', {
storeId: 'employeeStore',
fields: ['firstname', 'lastname', 'seniority', 'dep', 'hired'],
data: [{
firstname: "Michael",
lastname: "Scott"
}, {
firstname: "Dwight",
lastname: "Schrute"
}, {
firstname: "Jim",
lastname: "Halpert"
}, {
firstname: "Kevin",
lastname: "Malone"
}, {
firstname: "Angela",
lastname: "Martin"
}]
});
Ext.create('Ext.grid.Panel', {
title: 'Action Column Demo',
store: Ext.data.StoreManager.lookup('employeeStore'),
columns: [{
text: 'First Name',
dataIndex: 'firstname'
}, {
text: 'Last Name',
dataIndex: 'lastname'
}, {
xtype: 'actioncolumn',
width: 50,
items: [{
icon: 'app/resources/images/cog_edit.png',
// Use a URL in the icon config
tooltip: 'Edit',
handler: function (grid, rowIndex, colIndex) {
var rec = grid.getStore().getAt(rowIndex);
alert("Edit " + rec.get('firstname'));
}
}, {
icon: 'app/resources/images/delete.png',
tooltip: 'Delete',
handler: function (grid, rowIndex, colIndex) {
var rec = grid.getStore().getAt(rowIndex);
alert("Terminate " + rec.get('firstname'));
}
}]
}],
width: 250,
renderTo: Ext.getBody()
});
});
This is an example with an action column and a function in a controller:
View:
{
xtype: 'actioncolumn',
id:'actionColumnGridCas',
flex: 1,
hideable: false,
items: ['->',{
icon: '/images/user_edit.png',
tooltip: 'edit',
iconCls:'act-edit'
},
{
icon: '/images/user_delete.png',
tooltip: 'delete',
iconCls:'act-delete'
}]
}
Controller:
'.grid_alias actioncolumn[id=actionColumnGrid]': {
click: me.onActionColumnGridCasSelect
}
onActionColumnGridCasSelect: function(view, cell, rowIndex, colIndex, e) {
var m = e.getTarget().className.match(/\bact-(\w+)\b/);
if (m === null || m === undefined) {
return;
}
var action = m[1];
switch (action) {
case 'edit':
alert('edit');
break;
case 'delete':
alert('delete');
break;
}
}
I am trying to create a list on the fly and then show it dynamically in a navigation view but when I try and Do this, I get no errors and the list doesnt show. I was wondering how one can show a list from within a navigation view.
Ext.define('MyApp.view.Navigation', {
extend: 'Ext.navigation.View',
id: 'NavView',
xtype: 'navigationcard',
config: {
title: 'Schedule',
iconCls: 'settings',
//we only give it one item by default, which will be the only item in the 'stack' when it loads
items: [
{
xtype: 'mainview'
}
]
}
});
Ext.define('MyApp.view.Main', {
extend: 'Ext.TabPanel',
xtype: ['mainview','widget.mainview'],

]
}
});
var scheduleStore = Ext.create('Ext.data.Store', {
storeId: 'schedulestore',
fields: ['scheduleId', 'templateName', 'startDate', 'times'],
sorters: 'day',
grouper: {
groupFn: function (record) {
var startDate = $.datepicker.formatDate('DD, MM dd', new Date(record.get('startDate')));
return startDate;
},
sortProperty: 'startDate',
}
}); // create()
Ext.define('MyApp.view.Schedule', {

var self = Ext.getCmp('NavView');
var listRecord = list.getStore().getAt(index);
var scheduleId = listRecord.get('scheduleId');
var scheduleItem = GetScheduleItemById(scheduleId);
var button = Ext.create('Ext.Button', {
iconCls: 'compose',
text:'Forms',
iconMask: true,
handler: function () {
var self = Ext.getCmp('NavView');
var cListStore = Ext.create('MyApp.view.ScheduleFormsList');
var panelForms = Ext.create('Ext.Panel', {
id: 'panelForms',
items: [{ xtype: 'schedulecard' }]
});
var newView = {
title: scheduleItem.AppointmentType.Name,
id: 'ScheduleItemDetailForms',
items: [cListStore]
};
self.push(newView);
}
});
var panelScheduleDetails = Ext.create('Ext.Panel', {

});
var scheduleDetailsContainer = Ext.create('Ext.Container', {

var newView = {

Try adding the xtype of list in the main
Main.js
Ext.define('MyApp.view.Main',{
extend:'Ext.TabPanel',
xtype:'mainView',
id:'idMain',
config:{
tabBar:{
docked:'bottom',
hidden:true
},
items:[
{ xtype: 'schedulecard' }
]
}
});
Schedule.js
Ext.define("MyApp.view.Schedule", {
extend: "Ext.Container",
xtype: 'schedulecard',
config: {
title: 'Schedule',
iconCls: 'time',
layout:'fit',
items: [
{
xtype: 'navigationview',
id:'idScheduleListNavView',
items: [
{
xtype:'list',
onItemDisclosure:true,
loadingText: "Searching ...",
emptyText: "<div class=\"empty-text\">No Places Found.</div>",
id:'idSearchNavList',
store: 'schedulestore',
itemTpl: '<span style="font-weight:bold;">{templateName}</span><br/>{times}',
},
],
}
]
}
});
ScheduleController.js
In your controller create the new view and push it
Ext.define('MyApp.controller.ScheduleController',{
extend:'Ext.app.Controller',
config:{
refs:{
idScheduleList:'schedulecard',
navScheduleList:'#idScheduleListNavView',
},
control:{
'#idScheduleListNavView' : {itemtap:'showScheduleDetails'},
}
},
showScheduleDetails : function(){
var navScheduleList = this.getNavScheduleList();
navScheduleList.push(newView);
}
});

I'm using eclipse and LogCat tab keeps marking this red
02-08 11:11:58.741: E/Web Console(13886): Uncaught TypeError: Cannot read property 'contacts' of undefined at file:///android_asset/www/app.js:35
I'm guessing this has something to with why I can't see the contacts in the contactsListContainer.
Any help please?
I'm not a Sencha expert but I do know that this line:
var App = new Ext.Application({
will cause problems with PhoneGap as we also declare a variable called App. It would be better to change that line to be something like:
var myApp = new Ext.Application({
to avoid the name conflict.
If that doesn't resolve your problem I suggest you read over my post on searching contacts. I'd make sure I could successfully search for contacts before adding in Sencha.
