I'm working in Sencha Touch framework, and want to design a navigation bar to push my additional views. However, I want to add either my cardlayout (eg: xtype: 'mycard' ) or a widget (eg: xtype: 'my').
How can I push my existing view which is already defined as Ext.define('MyProject.view.my', {//some deination}). I tried the following code but unable to call in my handler function when the button pressed in navigation bar.
I'm absolutely unable to pushany view as it is not working in my handler function, and unable to call the view.push.
How can I get my view and push as a navigation item?
Tried Code for push some view:
//create the navigation view and add it into the Ext.Viewport
var view = Ext.Viewport.add({
xtype: 'navigationview',
//we only give it one item by default, which will be the only item in the 'stack' when it loads
items: [{
//items can have titles
title: 'Navigation View',
padding: 10,
//inside this first item we are going to add a button
items: [{
xtype: 'button',
text: 'Push another view!',
handler: function () {
//when someone taps this button, it will push another view into stack
view.push({
//this one also has a title
title: 'Second View',
padding: 10,
//once again, this view has one button
items: [{
xtype: 'button',
text: 'Pop this view!',
handler: function () {
//and when you press this button, it will pop the current view (this) out of the stack
view.pop();
}
}]
});
}
}]
}]
});
My Code:
{
xtype: 'button',
text: 'btn',
id: 'btn1',
scope: this,
handler: function(b, e) {
//here I want to push my view named as xtype: 'my'
// my main viewport has the xtype: 'main' and alias: 'widget.mypanel'
}
}
Try to create the view on the fly then add it to the view's items collection. I.e. in your event handler try to add
var view = Ext.create('MyProject.view.my', {});
this.add([view]);

how do I point this menu item click to launch a method in a controller.
The item click is being hit successfully but the error message states No method named "onDownloadTopdayRecapContextButton" on ExtApplication4.view.main.MainController. That is the problem, you can see the view's controller is portalRealtime-portalRealtime.
So somehow its pointing to the wrong controller. Can someone show me what I am doing wrong?
menu code
var contextMenuTopday = Ext.create('Ext.menu.Menu', {
items: [{
text: 'Download Topday Recap',
iconCls: 'downloadIcon',
listeners: {
click: 'onDownloadTopdayRecapContextButton'
}
grid menu is held in
Ext.define('ExtApplication4.view.portalRealtime.PortalRealtime', {
extend: 'Ext.panel.Panel',
xtype: 'app-portalRealtime',
itemId: 'portalRealtimeItemID',
requires: [
'ExtApplication4.view.portalRealtime.PortalRealtimeController',
'Ext.form.action.StandardSubmit'
],
controller: 'portalRealtime-portalRealtime',
title: 'Main Portal',
layout: {
type: 'vbox'
},
items: [
//i deleted some grid code here
collapsible: true,
collapseDirection: 'left',
listeners: {
itemcontextmenu: function (view, rec, node, index, e) {
e.stopEvent();
contextMenuTopday.showAt(e.getXY());
return false;
}
{
You are creating the context menu outside of your view, so it does not inherit your controller.
Before using the below code please scroll to the bottom of the answer for a better solution, but this hopefully shows what is the cause of your issue.
If this doesn't solve your issue, please comment and provide a more complete code example, and I will update my answer
In these cases you can pass a controller manually, but you need to pass as a parent, as you get all kinds of problems if you re-use the same controller on multiple components (when you destroy one for example, it destroys the controller, leaving the other without)
So you could create from within your view like so:
Ext.define('ExtApplication4.view.portalRealtime.PortalRealtime', {
initComponent:function(){
this.callParent(arguments);
this.contextMenuTopday = Ext.create('Ext.menu.Menu', {
controller:{
parent: this.getController()
},
items: [{
text: 'Download Topday Recap',
iconCls: 'downloadIcon',
listeners: {
click: 'onDownloadTopdayRecapContextButton'
}
}]
});
}
Then rather than use a variable to access the context menu you can access the contextMenuTopday property, as you are within a child item you may need to traverse to your actual view, the simplest way of doing this is via the up method available on components, you would need to make sure you include an xtype to do this:
Ext.define('ExtApplication4.view.portalRealtime.PortalRealtime', {
xtype:'portalrealtime'
Then from within the context menu you can do:
itemcontextmenu: function (view, rec, node, index, e) {
this.up('portalrealtime').contextMenuTopday.showAt(e.getXY());
}
A better way
Best illustrated looking at this fiddle: https://fiddle.sencha.com/#view/editor&fiddle/1qpn
Define your menu as its own class:
Ext.define('Example.ContextMenu', {
xtype:'testmenu',
extend:'Ext.menu.Menu',
items: [{
text: 'Download Topday Recap',
iconCls: 'downloadIcon',
listeners: {
click: 'onDownloadTopdayRecapContextButton'
}
}]
});
Use a method on your controller for the itemcontextmenu event (This is good anyway as it provides a better separation of concerns):
itemcontextmenu: 'showContextMenu'
Then add a a few new methods to your portalRealtime-portalRealtime controller:
getContextMenu:function(){
if(!this.contextMenu){
this.contextMenu = this.getView().add({xtype:'testmenu'});
}
return this.contextMenu;
},
showContextMenu:function (view, rec, node, index, e) {
// we can't use showAt now we have added this to our view, as it would be positioned relatively.
this.getContextMenu().show().setPagePosition(e.getXY());
}
What we are doing here is adding the context menu to the view, so it inherits the controller (and a viewmodel if provided).
The best way to call methods on your controller for listeners/button handlers etc is to just specify the method name as a string i.e.:
listeners:{
itemcontextmenu: 'showContextMenu'
}
This will automatically look up the responsible controller and use the correct method.
If you need to call from within a component you will find that this.getController() fails unless you call on the actual component the controller is attached to - i.e. you are calling from a child component. In these cases you can use this.lookupController() to find the inherited/responsible controller and then call any methods from here e.g. this.lookupController().myMethod()
Good Morning All,
I have an ExtJS 5 tabpanel. When the tabpanel first appears there is a single tab inside with a star for the title. What I need is when the user clicks the star for it to create a new tabItem. I have tried the activate event but that only works with more than one tab present. I have also tried binding to the a click event and nothing happens for that. Here is the code I have now:
{
xtype:'tabpanel',
itemId:'tabCtr1',
width:785,
items:[
{ iconCls: 'btn-NewTab', html : 'A simple tab' }
]
}
function assetDetailsDialog_AfterRender(sender, eOpts)
{
parent.down('tabpanel').items.getAt(0).on('click', function(){
alert('Hello World');
});
}
Thanks everyone
Follow On Issue:
I am having one more issue with setting the active tab. When the button is click it creates the new tab not issue, but when I call setActiveTab it appears to do nothing. When I stepped through it in Chrome I can see it is actually changing the tab to the specified one but then switching it back to the original. Any help would be great. Any idea's?
I have created a fiddle which demonstrates how to add tabs dynamically on click, the code is also listed below in case the link breaks. In the code below, the significant thing is adding the listener to the tabConfig
Ext.application({
name: 'Fiddle',
launch: function() {
var tabPanel = Ext.create('Ext.tab.Panel', {
width: 800,
height: 400,
renderTo: document.body,
items: [{
title: 'Click me to add another tab',
tabConfig: {
listeners: {
click: function(tab) {
alert("Adding another tab");
var newTab = tabPanel.add({
// we use the tabs.items property to get the length of current items/tabs
title: 'Tab ' + (tabPanel.items.length + 1),
html: 'Another one'
});
}
}
}
}, {
title: 'Bar',
tabConfig: {
title: 'Custom Title',
tooltip: 'A button tooltip'
}
}]
});
}
});
Most of this code was taken from the documentation here
I have a dynamic form and i want to add a listener when change a field value, but i couldnt achive to do that. I added a click listener but when i change it to the change it doesnt work.
thanks in advance.
here is the code below :
panel = Ext.define('MyApp.view.dynamicform.Form', {
extend: 'Ext.form.Panel',
alias: 'widget.dynamicformform',
title: title,
id: 'dynamicform.Form',
bodyPadding: 5,
autoScroll: true,
layout: 'auto',
defaults: {
anchor: '100%'
},
dockedItems: [],
items : genItems(storeData),
listeners: {
afterrender: function (comp) {
var element = comp.getEl();
element.on('change', function(e,el) {
alert('blabla')
});
}
},
initComponent : function() {
this.callParent(arguments);
}
});
when i write click instead of change it works perfectly. I dont get what iam doing wrong.
The afterrender event you have added the listener for is purely for the panel component alone. Therefore trying to attach a change event wont work, since you are trying to do this on the panel:
afterrender: function (comp) {
var element = comp.getEl();
//element is the panel here, not child items such as spinners...
element.on('change', function(e,el) {
alert('blabla')
});
}
You say the click is working, but I think that's just because you are clicking anywhere on the panel including on the child items you are rendering. Instead, the child items coming back in the genItems() need to contain change event listener configs.
EDIT
You could loop through the child items on comp in your afterrender event and for any that are spinners, etc, add the change events that way.
I have a Tab Panel as my initial item inside a Navigation View. When I change tab, I'm updating the Title in the Navigation Bar via:
activeitemchange: function(container){
var navigationView = container.up('navigationview'),
navigationBar = navigationView.getNavigationBar(),
newTabTitle = value.tab._title;
navigationBar.setTitle(newTabTitle);
}
The problem is that when I push a new view onto the Navigation View, the Text for the Back Button uses the old/original Title, and not the updated Title. Clicking the Back Button also sets the Navigation View Title to the old/original Title.
The closest I got to finding a solution was this:
http://www.sencha.com/forum/showthread.php?189284-Navigation-View-Title-(IPad-App)
But I get an 'undefined' error on the navigationBar.refreshProxy() call, so I'm assuming that only works for an older version of ST.
Any help would be great,
Thanks.
I don't know if you found any answer for this question or solved it by your own since question is quite old. But I tried what you wanted to do and I managed to get the result successfully. So here's the code. I'm following MVC strictly so posting necessary files that need this to work. Basically, views and controllers.
Main.js containing TabPanel
Ext.define('SO.view.Main', {
extend: 'Ext.tab.Panel',
xtype: 'main',
requires: [
'Ext.TitleBar',
'Ext.Video'
],
config: {
tabBarPosition: 'bottom',
items: [
{
title: 'Welcome',
iconCls: 'home',
styleHtmlContent: true,
scrollable: true,
html: [
"You've just generated a new Sencha Touch 2 project. What you're looking at right now is the ",
].join("")
},
{
title: 'Get Started',
iconCls: 'action',
items: [
{
xtype: 'button',
text: 'Push a new view!',
action:'push_new_view'
}
]
}
]
}
});
Nav.js having navigation view and default item as above tab panel
Ext.define('SO.view.Nav', {
extend: 'Ext.NavigationView',
xtype: 'nav',
config:{
fullscreen: true,
items: [
{
title: 'Default View',
xtype:'main'
}
]
}
});
And finally, controller. I did every user interaction handling in controller itself.
Ext.define('SO.controller.Nav',{
extend:'Ext.app.Controller',
config:{
refs:{
views:['SO.view.Main','SO.view.Nav'],
navView:'nav',
tabView:'main'
},
control:{
tabView:{
activeitemchange:'changeTitle'
},
'button[action=push_new_view]':{
tap:'pushNewView'
}
}
},
changeTitle:function(container,value,oldValue,eOpts ){
console.log(value.title);
this.getNavView().getNavigationBar().setTitle(value.title);
},
pushNewView:function(){
var activeTabTitle = this.getTabView().getActiveItem().title;
var controller = this;
controller.getNavView().push({
title: 'Second',
html: 'Second view!'
});
controller.getNavView().getNavigationBar().getBackButton().setText(activeTabTitle);
controller.getNavView().getNavigationBar().getBackButton().on('tap',function(self){
controller.getNavView().getNavigationBar().setTitle(activeTabTitle);
});
}
}
);
As you can see, I've attached function that changes title according to selected tab in changeTitle function.
the function pushNewView pushes new view and let's you ovverride back button behavior on tap. What I did is simply, get activeItem() from tab panel which holds a button that pushes new view. Once we got activeItem we can get it's title and that title need to be set to backButtnoText. So I traverse navigation view and getBackButton instance and simply by calling setText() method changed back button text.
Same time, I've attached event handler to back button, as we do want to change navigation bar title to previous title. So once, use taps back button, we set back the title to title we got in above step. You might want to detach event handler once you're done with eveything as it might cause problems or I'd rather say it'd be good.
Just try this, it just works.
You will need to change the title of the parent viewport, not just to the navigation view tile. Basically the Navigation title is already changing by itself based on the parent view title, and all pushed component title.
var view = Ext.create('Ext.NavigationView', {
fullscreen: true,
items: [{
title: 'Change this title ',
items: [{
xtype: 'button',
text: 'Push a new view!',
handler: function() {
view.push({
title: 'Second Title',
html: 'Second view!'
});
}
}]
}]
});
It should look something like this:
activeitemchange: function(container){
var newTabTitle = value.tab._title;
container.setTitle(newTabTitle);
}
//viewAppt is the reference of the view
//Use this
viewAppts.query('#headerTitlebar')[0].setTitle('Title');
// Instead of this
this.getApptsHeaderTitlebar().setTitle('Title');
Let's say I have a main controller, then my application has a controller for each "module". This main controller contains the viewport, then a header (with a menu) + a "centered" container, which is empty at the beginning.
A click in the menu will change the current module/controller and the adhoc view (which belongs to this controller) will be displayed in the centered container.
I think it's a very simple scenario, but strangely I didn't find the proper way to do it. Any ideas? Thanks a lot!
Here is what I do: I have a toolbar on top, a left navigation and the center location is work area (basically a tab panel) like you mentioned. Lets take each part fo the application and explain.First, here is how my viewport look like:
Ext.define('App.view.Viewport',{
extend: 'Ext.container.Viewport',
layout: 'border',
requires: [
'App.view.menu.NavigationPane',
'App.view.CenterPane',
'App.view.menu.Toolbar'
],
initComponent: function() {
Ext.apply(this, {
items: [{
region: 'north',
xtype: 'panel',
height: 24,
tbar: Ext.create('App.view.menu.Toolbar')
},{
title: 'Navigation Pane',
region: 'west',
width: 200,
layout: 'fit',
collapsible: true,
collapsed: true,
items: Ext.create('App.view.menu.NavigationPane')
},{
region: 'center',
xtype: 'centerpane'
}]
});
this.callParent(arguments);
}
});
You can see that I have a toolbar (App.view.menu.Toolbar) with menu and left navigation (App.view.menu.NavigationPane). These two, components make up my main menu or gateway to other modules. Users select the menu item and appropriate module views (like form, grid, charts etc) get loaded into the 'centerpane'. The centerpane is nothing but a derived class of Ext.tab.Panel.
Like you said, I have a main controller that handles all the requests from the toolbar and navigation pane. It handled only the toolbar and navigation pane's click actions. Here is my AppController:
Ext.define('CRM.controller.AppController',{
extend: 'Ext.app.Controller',
init: function() {
this.control({
'apptoolbar button[action="actionA"]' : {
click : function(butt,evt) {
this.application.getController('Controller1').displayList();
}
},
.
. // Add all your toolbar actions & navigation pane's actions...
.
'apptoolbar button[action="actionB"]' : {
click : function(butt,evt) {
this.application.getController('Controller2').NewRequest();
}
}
});
}
});
Look at one of my button's handler. I get hold of the controller through the 'application' property:
this.application.getController('Controller2').NewRequest();
With the help of getController method, I get the instance of the controller and then call any method inside my controller. Now lets have a look at the skeleton of my module's controller:
Ext.define('CRM.controller.Controller2',{
extend: 'Ext.app.Controller',
refs: [
{ref:'cp',selector: 'centerpane'}, // reference to the center pane
// other references for the controller
],
views: ['c2.CreateForm','c2.EditForm','c2.SearchForm','c2.SearchForm'],
init: function() {
this.control({
'newform button[action="save"]' : {
// Do save action for new item
},
'editform button[action="save"]' : {
// update the record...
},
'c2gridx click' : {
// oh! an item was click in grid view
}
});
},
NewRequest: function() {
var view = Ext.widget('newform');
var cp = this.getCp(); // Get hold of the center pane...
cp.add(view);
cp.setActiveTab(view);
},
displayList: function() {
// Create grid view and display...
}
});
My module's controller have only the actions related to that module (a module's grid, forms etc). This should help you get started with rolling in right direction.
In main controller add child controller in the click event handler of menu
Ext.define('MyAPP.controller.MainController',{
...
init:function()
{
this.control({
'menulink':
{
click:this.populateCenterPanel
}
});
},
populateCenterPanel:function()
{
this.getController('ChildController');
}
});
In launch function add listener to controller add event like this -
Ext.application({
...
launch:function(){
this.controllers.addListener('add',this.newControllerAdded,this);
},
newControllerAdded:function(idx, ctrlr, token){
ctrlr.init();
}
});
Now put code for dynamically embedding views in the viewport in init method of ChildController.
Ext.define('MyAPP.controller.ChildController',{
...
refs: [
{ref:'displayPanel',selector:'panel[itemId=EmbedHere]'}
]
init:function(){
var panel=this.getDisplayPanel();
panel.removeAll();
panel.add({
xtype:'mycustomview',
flex:1,
autoHeight:true,
...
});
}
});
HTH :)
