Edit: Upon further examination I discovered that I hadn't included certain namespaces. Adding the relevant name spaces now gives the error:
'myapp.mainpanel has no method setActiveItem'
I am trying to build a sencha touch web app using the card layout mechanism. I make use of the following handler on a button on the landing page:
handler:function(){
myapp.mainpanel.setActiveItem(myapp.cards.vehicleSearchResults, { type: 'slide', cover: false, direction: 'left'})
}
But when I click on the button I get the error: Sencha Touch error: 'myapp.mainpanel has no method setActiveItem'
Does this mean myapp.cards.vehicleSearchResults is undefined?
I define it here:
myapp.cards.vehicleSearchResults = new Ext.Panel({
scroll:false,
layout:{
type:"vbox",
align:"stretch"
},
id: "vehicle-search-results-card",
dockedItems: [myapp.toolbars.searchResultsTitle, myapp.toolbars.searchResultsNav, myapp.toolbars.searchResultsCaption]
})
Any clues as to what I am doing wrong based on the above code?
The setActiveItem() method is only available if the panel has a card layout. Make sure you add the 'card' layout property in your panel definition.

I'm trying to use .setActiveItem to display detailed info on items in a listview (Ext.dataview.List) in a Sencha 2.1 MVC app. The problem is that I can't get the detailed view to load the data.
I've tried many different methods of getting the detailed view to show data including setData, setRecord and Update (see below for some of my latest tries).
Most of the results I keep getting when searching the forums, stackoverflow and google are for sencha apps not using the MVC model.
(Oh, using .push this works fine but due to other reasons I'm moving away from the navigation view).
From my controller:
showDetail: function(list, record) {
/*this.getMain().push({
xtype: 'labdetail',
title: record.fullName(),
data: record.getData()
});*/
//The code above works, but only as long as I stay with navigation view...
console.log("showDetail");
//Ext.getCmp('labdetail').update(record.data);
//LabDetail.update(record.data);
//Ext.fly('labdetail').setData(record.data);
//Ext.getCmp('labdetail').setData(record.data);
//Ext.component('Labblistan.view.LabDetail').destroy();
//Ext.getCmp('Labblistan.view.LabDetail').destroy();
//Ext.fly('labdetail').destroy();
//var DetailView = Ext.create('Labblistan.view.LabDetail'); //If I create the view the console complains I need to destroy previous views with the same ID, hence the different destroy() approaches above
//DetailView.setRecord(record);
Ext.getCmp('mainpanel').setActiveItem('labdetail'); //This navigates to the right view, but it's empty
},
My detailview:
Ext.define('Labblistan.view.LabDetail', {
extend: 'Ext.Panel',
xtype: 'labdetail',
id: 'labdetail',
config: {
title: '{Analysis}',
styleHtmlContent: true,
scrollable: 'vertical',
fullscreen: true,
tpl: [
'<div style=position:absolute;top:50px;><p>Info about {Analysis}</p><p>{Comment}</p></div>'
],
},
});
Don't know if this is best practice but this is how I got it working:
Ext.getCmp('mainpanel').setActiveItem({
xtype: 'labdetail',
title: 'Detaljinformation',
data: record.getData()
});
I want to show the data from the following API in List :
http://customer.appxtream.com/astro.apps.cms/jsonFeed.action/?service=astroSportsDataService&action=grabJsonText&mimeType=application/json&p1=HighlightNewsList&p2=EURO2012
when I get the data, the Network of Chrome shows me that all elements have been retrieved but List shows only the data from the last item in the API here is my code:
View
Ext.define('astro.view.HighliteNews', {
extend: 'Ext.DataView',
xtype: 'highliteNews',
config:{
title:'xren',
store: 'highliteNewsStoreId',
itemtap: true,
scrollable:'horizontal',
inline:{
wrap:false
},
itemTpl:[
'<div><img src="{imageLink}"/> </div>',
],
},
});
Store
Ext.define('astro.store.HighliteNewsStore',{
extend: 'Ext.data.Store',
xtype:'highliteNewsStore',
config:{
model: 'astro.model.HighliteNewsModel',
autoLoad: true,
storeId: 'highliteNewsStoreId',
proxy:{
type:'ajax',
url :'http://customer.appxtream.com/astro.apps.cms/jsonFeed.action',
extraParams:{
service:'astroSportsDataService',
action:'grabJsonText',
p1:'HighlightNewsList',
p2:'EURO2012',
mimeType:'application/json'
},
reader:{
type:'json',
rootProperty:'cmsHighlightNewsList',
},
},
}
});
Model
Ext.define('astro.model.HighliteNewsModel',{
extend: 'Ext.data.Model',
config:{
fields: ['imageLink'],
}
});
So the network shows that 3 images are sent from API but the List shows ONLY LAST IMAGE.
Please help
I solved the problem guys :) , there is an conflict between Sencha and JsonP, so if you assign a idproperty to your Model, the problem will be sloved :
config:{
idProperty: 'HighliteIdProperty',
fields: ['imageLink'],
}
A few things I would suggest :
Add a listener to the load event of the store
This is just to check that all the data is load in your store.
You can do it in different ways :
In a controller
store.on({
load:function(){
console.log(store.getCount());
}
});
or directly in the store config with the listeners attribute
listeners:{
load:function(store){
console.log(store.getCount());
}
}
Check the DOM
In the Web Inspector / Firebug, check if your items are there or only the last one.
I think you could also try this command in the console :
Ext.DomQuery.select('div[class=x-dataview-item]').length
It will return the number of items in your dataview.
Set a width and height to your image
I also had the same problem with a dynamically loaded dataview. All the picture were there in the DOM but too small to be seen. So I suggest, you give them a CSS class with a defined width and height.
That's all I can think of for now.
Hope this helps
Thanks Arash for this question and answer. We are facing similar problem and found that we didn't have model defined. Defining the model worked in our case. However, it worked while we retrieved playlist from youtube and now while retrieving the list from google spreadsheet. Hope this helps others who are using google spreadsheet.
adjust the height in the config of view......this might be a problem
I am trying to take a picture using camera in Sencha Touch 2. Here i have one button 'Take a Picture', when i will press it, camera should start. As i am new to this sencha touch 2, i am unable to figure it out, how to do this?
For this i used the below code:
Sencha Fiddle Link
Please help me. I do not want to use Phone gap.
You have to add device folder of Sencha Library in root directory
and add below code in
Ext.require('Ext.device.Camera');
and use this code for capture image using camera
Ext.device.Camera.capture({
success: function(image) {
imageView.setSrc(image);
},
quality: 75,
width: 200,
height: 200,
destination: 'data'
});
If you want to use purely sencha, then you can check this code:
xtype: 'button',
handler: function(button, event) {
Ext.device.Camera.capture({
source: 'camera',
destination: 'data',
success: function(imagedata) {
var img = Ext.getCmp('theimage');
img.setSrc('data:image/jpeg;base64,' +imagedata);
},
failure: function() {
Ext.Msg.alert('Error', 'There was an error when acquiring the picture.');
},
scope: this
});
But if you want to use phonegap camera features, may be you have to change the code. As sencha is giving the default feature to handle the camera, i wish not to go with phonegap. Hope it will help..
I am using the Sencha Touch framework for the development of my iPad application.
I am in need of using Map as a part of the screen(say half a page). When I try to do put a map component into my page, its covering the full page overlapping the previous components.
Please share your suggestions.
Thanks in advance,
Easwar
Please post some code to show what you have done / tried yourself so far.
Anyway, I think you're looking for the method: http://docs.sencha.com/ext-js/4-0/#!/api/Ext.form.Panel-cfg-dockedItems
var panel = new Ext.panel.Panel({
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
items: [{
text: 'Docked to the top'
}]
}]
});
So working though the mostly absent docs on templates - unable to get it to work.
Ext.define('MyAPp.view.Login', {
extend: 'Ext.Component',
xtype: 'welcomeLogin',
config: {
html: 'This shows',
tpl: Ext.create ('Ext.XTemplate', '<div>Please show something</div>', {
compiled: true
})
}
});
Why does the template content now show? I have tried adding apply(), applyTemplate() on and on and on... Please help!!!
#ilija139 is right.
you need to define the data property, even if it's empty.
data: {}
Edit:
Also, the compile attribute isn't needed. It only applies to Ext.Templates not XTemplates (according to the docs). Works the same for me without compile
