Sencha touch - change back button text for image in NavigationBar - sencha-touch

I'm usign Sencha Touch 2.1 so this code should work (link I used for inspiration):
defaultBackButtonText: null,
useTitleForBackButtonText: false,
backButton: {
// ui: 'toolbar-back',
// align : 'left',
iconCls: 'back',
iconMask: true
},
But I can still see icon and text as well.
Thanks a lot.

I use an empty string instead of null for defaultBackButtonText, and it removes the text (also using ST 2.1):
defaultBackButtonText: '',
EDIT: To clarify, this is an example of the full config for a nav view with a back button using an icon with no text:
Ext.define('MyApp.view.GroupNavView', {
extend: 'Ext.navigation.View',
xtype: 'groupnavview',
config: {
defaultBackButtonText: '',
navigationBar: {
backButton: {
iconCls:'arrow_left',
iconMask: true,
ui: 'dark',
cls: 'backButton'
}
},
items: [
{
xtype: 'mylist'
}
]
}
});

I think there is no "back" iconCls available in the default theme. Try using some other icon like "home". Also, you missed the navigationBar config. It should be like this:
defaultBackButtonText : null,
navigationBar: {
backButton : {
align : 'left',
iconCls: 'home',
iconMask: true,
ui : 'plain'
}
},
As I tested, I see only home icon there - nothing else.

How to change text in back button in a detailed view sencha touch?

What is the proper way to change the back button text?
Ext.define('myapp.view.post.PostDetail', {
extend: 'Ext.Panel',
alias: 'widget.postdetailpage',
xtype: 'postdetailpage',
config: {
navigationBar: {
config: {
//change the back button text?
defaultBackButtonText: 'Go Back',
useTitleForBackButtonText: false
}
},
scrollable: 'vertical',
styleHtmlContent: true,
tpl: ['{content}'],
}
});
The backbutton text is set in the navigation view before displaying the detailed view.
Ext.define('mimo.view.PostPanel', {
extend: 'Ext.NavigationView',
xtype: 'postPanel',
requires: [
'mimo.view.post.PostList'
],
config: {
title: 'Blog',
iconCls: 'home',
// set the back button text here
defaultBackButtonText: 'Volver',
items:[{
title: 'Las entradas de blog',
xtype: 'postlist'
}]
}
});
</pre>
You are extending Ext.Panel. Ext.Panel does not accept the navigationBar configuration, you probably want to use Ext.navigation.View. Then on that view you can pass the defaultBackButtonText property. Otherwise if you want to customize the button further, inside of navigationBar object you want to specify a button object with button properties.

Listener to Tab Item Click in Sencha

In my application, I'm using a tab panel with 5 items in it. Each item holds around 6 panels added in card layout. When I'm at the last panel inside a tab item, I need to get back to the initial panel by clicking on the bottom tab panel (somewhat similar to a normal tab view controller in iOS). I have came across some solutions I found here, but it seems to work only when I switch between the tabs. In fact I want to listen to the click event on the same tab icon. How can I do this?
I have worked on your problem. I think this is exactly what you want. Hope this helps. If not so, please leave a comment.
1). View (MyTabPanel1.js)
Ext.define('MyApp.view.MyTabPanel1', {
extend: 'Ext.tab.Panel',
config: {
scrollable: 'vertical',
items:
[
{
xtype: 'panel',
id:'cardpanel1',
title: 'Tab1',
layout: 'card',
items: [
{
html: "First Item",
items:
[
{
xtype: 'button',
text: 'Forward',
handler: function() {
Ext.getCmp('cardpanel1').setActiveItem(1);
console.log('Going to Second Item');
}
}
]
},
{
html: "Second Item",
items:
[
{
xtype: 'button',
ui: 'confirm',
text: 'Go back',
handler: function() {
Ext.getCmp('cardpanel1').setActiveItem(0);
console.log('Going to First Item');
}
}
]
}
]
},
{
xtype: 'panel',
title: 'Tab2',
scrollable: true,
items: [
{
xtype: 'button',
margin: 10,
ui: 'action',
text: 'Tab2'
}
]
},
{
xtype: 'panel',
title: 'Tab3',
scrollable: true,
items: [
{
xtype: 'button',
margin: 10,
ui: 'action',
text: 'Tab3'
}
]
}
]
}
});
2). Controller (MainController.js)
Ext.define('MyApp.controller.MainController', {
extend: 'Ext.app.Controller',
config: {
control: {
"tabpanel #ext-tab-1":{ //ext-tab-1 is the id for the 1st tab generated by Sencha
tap: 'ontap'
}
}
},
ontap: function (){
console.log('inside controller');
Ext.getCmp('cardpanel1').setActiveItem(0);
}
});
I would give a much simpler solution
This is my view called Viewport which is a TabPanel:
Ext.define('Sencha.view.iphone.Viewport',{
extend: 'Ext.TabPanel',
xtype: 'newviewport',
alias: 'widget.newTabPanel',
Now in my controller file:
Ext.define('Sencha.controller.iphone.main', {
extend: 'Ext.app.Controller',
config:
{
refs: {
theMainTabPanelTabbarTab: 'newTabPanel > tabbar > tab', //this the tab of the tabpanel, if we listen to it that way we will know of tab panel tap.
},
control: {
theMainTabPanelTabbarTab:{
tap: 'onTapMainTabPanel'
}
}
This is a working code and works fine. Hopefully this will help you.

Add (right) Button to Sencha Navigation View

I want to dynamically add a (right aligned) button to the active navigation view depending on view Im showing. Is there any proper way to do it? I found many half good examples online, but didnt get them to work. Here is what I tried:
Ext.define('Sencha.view.user.Login', {
extend:'Ext.navigation.View',
//fullscreen: true,
xtype: 'loginview',
requires:[
'Ext.form.FieldSet',
'Ext.field.Email',
'Ext.field.Password'
],
config: {
title: 'Log in',
iconCls: 'use',
cls: 'kidsbackground',
scrollable: false,
navigationBar: {
items: [
]
},
items:[
{
xtype: 'loginform'
}
]
},
addRightButton:function(button){
var navigationBar = this.config.navigationBar;
console.log("navigationBar: "+navigationBar);
var rightButton = Ext.Button.create({
xtype: 'button',
ui: 'action',
iconCls: 'action',
iconMask: true,
align: 'right' });
console.log("rightButton: "+rightButton);
//navigationBar.addItem(rightButton);
var oNavigationbar = {
docked: 'top',
backButton : {
margin: 7,
docked: "left",
ui : 'back'
},
items: [
Ext.create("Ext.Button", {
text: "Button1"
}),
Ext.create("Ext.Button", {
text: "Button2",
align: "right"
})
]
};
this.setNavigationBar(oNavigationbar);
/*this.setNavigationBar({
items: [
{
id: 'rightButton',
xtype: 'button',
text: 'yes!'
//placeHolder: 'Search...',
//align: 'right'
}
]
});*/
console.log("wow, no crash, really ?");
}
});
When I run the above code I get strange errors, one of this is this (see attachment):
You can try this code (in Chrome Developer Tools' console) on the Sencha Touch 2 Navigation View example :
Ext.ComponentQuery.query('navigationview')[0].getNavigationBar().add({
xtype:'button',
text:'Right',
align:'right'
});
It basically get the navigationview, then the navigation bar of this view and finally add the button to it.
This is the proper way to add a button to the navigation bar.
Hope this helps
different way
var navigationView = Ext.create('Ext.NavigationView',
{
useTitleForBackButtonText: false,
scrollable: false,
layout:
{
type: 'card',
animation: null
},
navigationBar:
{
items:
[
{
xtype: 'togglefield',
name: 'smsmode',
align: 'right',
value: 0,
disabled: true
},
{
text: '',
iconCls: 'delete',
align: 'right',
ui: 'back',
listeners:
{
tap: function()
{
navigator.app.exitApp();
}
}
}
]
}
});

How to aligh in the centre of the screen with Sencha Touch

I'm using Sencha Touch, at the moment I'm adding to the view some HTML code and underneath a button. I would like have the content of the HTML code together with the button to be in the centre of the screen.
Could you suggest me how to do it? thanks for your time
Ext.define('Project.view.SettingsSuccess', {
extend: 'Ext.Panel',
xtype: 'settingformsuccess',
config: {
title: 'Settings',
iconCls: 'info',
cls: 'settings-success',
scrollable: true,
styleHtmlContent: true,
items: [
{
xtype: 'titlebar',
docked: 'top',
title: 'Settings',
items: [
{
xtype: 'spacer'
},
{
text: 'Back',
ui: 'back'
}
]
},
{
html: [
'<p>You have successfully authorised.</p>'
].join("")
},
// Go to Dashboard Button
{
xtype:'button',
text: 'Visit your Home Page',
ui: 'normal'
}
]
}
});
Try that:
Pack the Html Content and the Button in a Container:
http://docs.sencha.com/ext-js/4-0/#/api/Ext.container.Container
Place the Container where you want, see the setPosition(..) Method:
http://docs.sencha.com/ext-js/4-0/source/Component3.html#Ext-Component-method-setPosition

Sencha Touch v2 toolbar title alingment

When I create a toolbar like below the title is misplaced to the right of the last button, any ideas how to fix it?
{
xtype: 'toolbar',
docked: 'top',
title: 'Chat',
items: [{
xtype: 'button',
text: 'Places',
ui: 'back',
id: 'backToPlaces'
},
{
xtype: 'spacer'
},
{
xtype: 'button',
text: 'People',
ui: 'forward',
id: 'toProfiles'
}
I was also fighting with the toolbar. Then I discovered the navigationbar.
The title is in the center. With a button aligned left and right. (see align property)
{
docked: 'top',
xtype: 'navigationbar',
title: 'Chat',
items: [
{
xtype: 'button',
ui: 'back',
action: 'back',
text:'BACK',
itemId: 'backButton'
},
{
xtype: 'button',
ui: 'decline',
action: 'cancel',
text:'Cancel',
itemId: 'cancelButton',
align : 'right'
}
]
}
just after answered this, i found the "centered" attribute and looked at creation of title element of sencha, so just forget this above and use in your config:
var myToolbar = new Ext.Toolbar({
docked : 'top',
title: {
title: 'my Title',
centered: true
},
items : []
});
In Sencha 2 there is no "special" title element, it is created as simple element in the "items". So i future, you can just add it at right place direcly by placing the config to your docked bar:
var myToolbar = new Ext.Toolbar({
docked : 'top',
items : [{
xtype: 'spacer',
},{
xtype: 'title',
title : 'Hello World'
},{
xtype: 'spacer',
}]
});
Only with spacer it is in the middle.
It is clearly stated in the docs that NavigationBar is a private class for internal use by the framework http://docs.sencha.com/touch/2-0/#!/api/Ext.navigation.Bar and the centered attribute metioned by anj does not work as expected (at least in the latest release).
According to this post http://www.sencha.com/forum/showthread.php?161082-PR3-Toolbar-title-position-broken-when-spacers-control-button-positioning&p=691928 it is simply a bug that the title is not centered and we should wait for next release. In the meantime you might use navigationbar if you need to.
If you want to leverage something similar to how titles in Toolbar behaves of Ext.navigation.Bar. see the Ext.TitleBar http://docs.sencha.com/touch/2-0/#!/api/Ext.TitleBar
This class handles things like long titles for you by automatically adding ellipses and the title is always centered horizontally.
There is no longer a NavigationBar component which is public. It is simply used internally by NavigationView. You should never use this.
Instead, you should use Ext.TitleBar. This allows you to center the title config and also use the align property on items (normally buttons) to align them to the left or right.
It also has built in support when the title is too long, or any items are too wide. It will automatically limit the length of all items to a certain width, and add ellipse to the title if needed.
Here is a simple example:
var titleBar = Ext.create('Ext.TitleBar', {
docked: 'top',
title: 'Navigation',
items: [
{
iconCls: 'add',
iconMask: true,
align: 'left'
},
{
iconCls: 'home',
iconMask: true,
align: 'right'
}
]
});
Ext.Viewport.add(titleBar);
