I'm new to Sencha Touch and just trying to put a Toolbar inside of a TabPanel.
I do that because the TabPanel will be my main navigation and the Toolbar will provide several content-related operations, such as creating a new homework or sth like that.
Here is my "solution", that crtly doesn't work. The TabPanel appears, and the "Hello World" do so, too, but there won't be any Toolbar.
var tapHandler = function(btn, evt) {
alert("Button "+btn.text+" tapped");
}
var HomeScreen = new Ext.Panel({
fullscreen: true,
dockedItems: [
{
xtype: "toolbar",
title: "buttons",
ui: "light",
dock: "bottom",
items: [
{ui: "action", text: "Add"}
],
defaults: {
handler: tapHandler
}
}
],
html: "Hello World"
});
new Ext.Application({
name: "Hello World",
launch: function() {
var tabPanel = new Ext.TabPanel({
fullscreen: true,
ui: 'dark',
sortable: true,
items: [
{
title: "Home",
html: "Loading..."
}
]
});
tabPanel.items.get(0).update(HomeScreen, true);
}
});
Do you have any solutions?
Greetings,
Martin
I think the problem here may well be that the update() method expects an HTML string and HomeScreen is an Ext.Panel.
If it were me, I'd be adding HomeScreen to the items collection in tabPanel either by using the variable like this:
items: [
HomePanel
]
Or by defining it inside the items array as an object:
items: [{
xtype: "panel",
html: "Hello world",
dockedItems: [{
// You toolbar definition
}]
}]
Or by using the TabPanel.add() method:
tabPanel.add(HomePanel);

I'm new in Extjs. I would like to know. Which components I can use, to make a menu and toolbar like in desktop app?
I mean something like this.
I wrote this code, but the result is not similar to desktop app menu.
Ext.define('untitled.view.main.Main', {
extend: 'Ext.panel.Panel',
xtype: 'app-main',
width: 200,
height: 150,
tbar: [{
xtype: 'button',
text: 'Select',
menu: Ext.create('Ext.menu.Menu', {
items: [{
text: 'JavaScript',
handler: function () {
alert('Selected JavaScript');
}
}, {
text: 'Java',
}, {
text: 'C/C++'
}]
})
}]
});

Thank you very much, and the last question. How can I remove this arrow?
Here is fiddle for you - desktop-like toolbar (use your iconCls for Icon buttons).
Ask if you need something updated.
I just started using ExtJS 3.4 version. And I was not sure how to access the items within the panel when there is no id or itemId assigned to it. I have used Ext JS 4.2 before but I need to use 3.4 version for now.
In my case, I am using border layout here. I have a tree panel on the east region and a tabpanel in the center region. And I want to update the center region dynamically with grids or forms based on the tree node clicked.
here is my code for the tabpanel
{
xtype : 'tabpanel',
title : 'Center Panel',
width : 200,
region : 'center',
items:[gridpnl]
}
And here is the complete code that I tried
First ExtJs Page
Ext.onReady(function () {
Ext.namespace('Class');
Class.create = function() {
return this.init(config);
}
};
Ext.namespace('FirstOOPS');
FirstOOPS = Class.create();
FirstOOPS.prototype = {
init: function (config) {
var store= new Ext.data.ArrayStore({
fields: [{name: 'C1'},{ name: 'C3'}, {name: 'C5'}]
});
var myData= [['abcdC11','C3','C5'],['asdf','C3_asdf','C5_asdf']]
store.loadData(myData);
var gridpnl= new Ext.grid.GridPanel({
layout: 'fit',
height: 500,
width: 500,
store: store,
columns:[
{header: "C1", dataIndex: 'C1'},
{header: "C3", dataIndex: 'C3'},
{header: "C5", dataIndex: 'C5' }
]
});
var mainPanel = new Ext.Panel({
layout : 'border',
items : [
{
region: 'east',
collapsible: true,
title: 'Navigation',
xtype: 'treepanel',
width: 200,
autoScroll: true,
split: true,
loader: new Ext.tree.TreeLoader(),
root: new Ext.tree.AsyncTreeNode({
expanded: true,
children: [{
text: 'Grid',
leaf: true
}, {
text: 'Form',
leaf: true
}]
}),
rootVisible: false,
listeners: {
click: function(n) {
if(n.text=='Grid'){
Ext.Msg.alert(n.text);
}
}
}
},{
xtype : 'tabpanel',
title : 'Center Panel',
width : 200,
region : 'center',
items:[gridpnl]
}
]
});
new Ext.Viewport({
layout : 'fit',
items : [mainPanel]
});
}
};
var firstObj = new FirstOOPS();
});
</script>
</body>
</html>
Can someone tell me how to access this without id, so that I can update the tabpanel dynamically or create new tabs based on the tree node click.
Thanks in advance
you can use the following code to access tabpanel without using id or items id
this.up().items.items[1]
to test the above code I am alerting the title of the tab panel by following code
alert(this.up().items.items[1].title);
it will alerts the title of the tab panel
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.
I'm trying to get my test project working and have it set out with various viewports js files for each screen. I have now managed to load the data onto the screen with the code below however I am struggling with trying to set-up the onItemDisclosure function so that it switches to a detailed view which shows more information about the selection item.
MobileApp.views.Settings_screen = Ext.extend(Ext.Panel, {
title: "Settings ",
iconCls: "settings",
fullscreen: true,
layout: 'card',
dockedItems: [{
xtype: "toolbar",
title: "Settings"
}],
initComponent: function() {
detailPanel = new Ext.Panel({
id: 'detailPanel',
tpl: 'Hello, World'
}),
this.list = new Ext.List({
id: 'indexlist',
store: MobileApp.listStore,
itemTpl: '<div class="contact">{firstName} {lastName}</div>',
grouped: false,
onItemDisclosure: function() {
MobileApp.views.setActiveItem('detailPanel');
}
});
this.items = [this.list];
MobileApp.views.Settings_screen.superclass.initComponent.apply(this, arguments);
}
});
Ext.reg('settings_screen', MobileApp.views.Settings_screen);
I have tried to put some code here to switch to the detailPanel but it comes up with an undefined error.
onItemDisclosure: function() {
MobileApp.views.setActiveItem('detailPanel');
}
Thanks Aaron
You need to define this panel under Settings_screen's namespace, like this:
this.detailPanel = new Ext.Panel({
id: 'detailPanel',
tpl: 'Hello, World'
}),
Also, you need to add the detailPanel to the Settings_screen's items, so that it will become an item of it.
this.items = [this.list, this.detailPanel];
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());
