I am trying to create a universal titlebar with a back button for my application. I am including it in the various views by using {xclass:mUserStories.view.titlebar}.
Here is the code for the titlebar:
Ext.define('mUserStories.view.titlebar', {
extend: 'Ext.TitleBar',
id: 'narwhal',
config: {
docked: 'top',
// id: 'narwhal',
title: 'CHW Module',
items: [{
ui: 'back',
text: 'Back',
id: 'backButton'
// hidden: true
}]
}
})
However, when I try to dynamically change the toolbar when switching to different pages, the console.log of the titlebar says the _title has changed but the text on the titlebar and the "hidden" property of the button does not change.
Here is the code for the logic that occurs when the button is pressed to switch the page:
toPage: function (arg) {
var t = Ext.getCmp('narwhal');
var b = Ext.getCmp('backButton');
console.log(t,b)
if (arg === PAGES.PATIENT_LIST) {
t.setTitle('Patient List');
b.setHidden(true)
}
Ext.getCmp('viewPort').setActiveItem(arg);
}
I have also tried to include a ref at the top for Narwhal : '#narwhal' and use var t = this.getNarwhal(), but this does not work either.
I am not sure if the problem lies with where the id is being kept, how the id is being called, or because the page is not refreshing properly. Any advice would help!
Thank you for your time :)
I have had the same situation in my project.
I managed to get everything to work like you want it by having a controller owning a reference to the title bar and listening to activeItemChange on my tabPanel.

I have a togglefield in sencha as below
{
xtype: 'togglefield',
name: 'pushnotifications',
id: 'pushnotifications',
label: 'Enable Push Notifications?',
labelWidth: '40%',
height: '100%',
listeners: {
change: function(field, thumb, enabled) {
alert('sss');
}
}
}
The problem is that the event 'change' works only when the toggle button is dragged and not when it is changed by clicking.
How can I get the listener working even when clicking?Is there any other event that I am missing?
It's likely related to the id field. If views are not destroyed correctly and you end up with multiples of the same ID in the DOM then the event wiring can go wonky.
If you've used the id for a ref in the controller then try using the xtype instead.
I have an Ext.Panel with a card layout nested inside a navigation view. I did this to easily switch between a map and a list without having to pop and then push a whole different view (basically to avoid the animation). So, I have a button in the navigationBar that fires an action in the controller. This initial view, with a list, load fine, but the controller code to switch between the views (using setActiveItem()) does not work. No error message. I found something about a bug where you have to call show(). Although this works, it overlays the new activeItem (the Map, in this case) on top of the navigaionBar! (see screenshot). Also, if I just change activeItem to 1 in the config of the wrapper manually, it shows the map just fine, same as the list.
My wrapper panel looks like this:
Ext.define(ViewInfos.VendorWrapper.ViewName,{
extend: 'Ext.Panel',
id: ViewInfos.VendorWrapper.PanelId,
xtype: ViewInfos.VendorWrapper.Xtype,
config:
{
layout: 'card',
title: Resources.VendorsNearby,
activeItem: 0,
items: [
{
xtype: ViewInfos.VendorList.Xtype, //Initially shown, a list
},
{
xtype: ViewInfos.VendorMap.Xtype, //What I'm trying to show, a map
}
]
}
});
and here is my controller code:
Ext.define('OrderMapper.controller.VendorWrapper', {
extend: 'Ext.app.Controller',
config: {
refs: {
vendorMap: ViewInfos.VendorMap.Xtype,
vendorList: ViewInfos.VendorList.Xtype,
vendorWrapper: ViewInfos.VendorWrapper.Xtype,
main: ViewInfos.Main.Xtype,
vendorToggleButton: (ViewInfos.Main.Xtype + ' button[action=vendorViewToggle]')
},
control: {
vendorToggleButton:{
tap: function(){
var curView = this.getVendorWrapper().getActiveItem().id;
//active view == VendorList
if(curView == 'VendorList'){
//this shows up in the console
console.log('vendorToggleButton tapped, switching to map');
this.getVendorWrapper().setActiveItem(1);
//without this line, the view doesn't even change
this.getVendorWrapper().show();
this.getVendorToggleButton().setText('List');
}
//active view == VendorMap
else if (curView == 'VendorMap'){
console.log('vendorToggleButton tapped, switching to list');
this.getVendorWrapper().setActiveItem(0);
this.getVendorToggleButton().setText('Map');
}
}
}
}
}
And here is the screenshot of the wonky view that happens on this.getVendorWrapper().show()
Also, I tried changing the wrapper to a Carousel (instead of a regular panel with a card layout), and the carousel will swipe to change list/map but setActiveItem() STILL doesn't work.
I'm currently working on a navigation.View where there is basically 4 main views from where you can push other subview. I did it like this :
Ext.define('App.view.Navigation', {
requires: [
...
],
xtype: 'mainviews',
extend: 'Ext.navigation.View',
config: {
cls: 'content',
layout:{animation:false}, // or whatever animation you want for push and pop
navigationBar: {
...
},
items: [{
xtype: 'container',
layout:'card',
items: [{
xtype: 'mainview1',
},{
xtype: 'mainview2',
},{
xtype: 'mainview3',
},{
xtype: 'mainview4',
}]
}]
}
});
Then it's really easy to either set the active item of the navigation view or push subviews
For instance, in a controller it would be
this.getMainviews().setActiveItem(X); // X = 0,1,2 or 3
and
this.getMainviews.push(view); // view = the view your want to push
and these is the references :
refs:{
mainviews: 'mainviews'
}
Hope this helps
First of all, if you just want to avoid the animation on push/pop, add this config to your navigation view:
layout: {
animation: null
}
Generally, you should not call .show() on items that are inside your Ext.navigation.View instance. They will be added to Ext.Viewport directly, thus appearing to be on top of the navigation bar.
Have a look at this JSFiddle example, might give you a hint.
I'm using extjs4 and I'm trying to create a tab panel, that each tab has a different grid that loads data from a store. (each grid different store)
I would like to load the particular store only when the user clicks on the respective tab.
I don't see how I can catch the user click on the panel.
How I can do that?
I had a similar performance loading issue and failed to solve it with deferredRender. You have to add the event activate for the tab you want to load when the tab is activated :
{
title: 'tab2',
bodyPadding: 10,
html : 'A simple tab',
listeners: {
'activate' : function(){
store2.load();
},
}
}
Worked fine for me even if it's a temporary solution. Extjs 4.1 should improve loading/rendering performances. We'll see.
You can activate the panel by placing setActiveItem() in tab handler.
Ok, I figured out, I just needed to have deferredRender=true and to add the respective store.load() on the beforerender event on every tab:
var lowerTabPanel = Ext.create('Ext.tab.Panel', {
deferredRender: true,
items: [
{
title: 'tab1',
bodyPadding: 10,
html : 'A simple tab',
listeners: {
'beforerender' : function(){
store1.load();
},
}
},
{
title: 'tab2',
bodyPadding: 10,
html : 'A simple tab',
listeners: {
'beforerender' : function(){
store2.load();
},
}
},
]
});
Ext.TabPanel has config option deferredRender. May be it helps you.
Documentation:
true by default to defer the rendering of child items to the browsers DOM until a tab is activated. false will render all contained items as soon as the layout is rendered. If there is a significant amount of content or a lot of heavy controls being rendered into panels that are not displayed by default, setting this to true might improve performance.
Update: Also look at autoLoad config option in Ext.data.JsonStore, it should be false.
i have a panel which should show the "description" field of "currently activeitem of nestedlist". nestedlist uses the model having fields:
id
text
description
when user taps on any item of nestedList [on selectionchange OR itemtap&backtap], i want to change description in the panel with description of "currently activeItem of nestedList".
Is this possible?
thanks for any help/solution/pointer.
The same problem I had today, and no solution had been found with a nested list, because no single field can be taken from a Ext.data.TreeStore. One solution could be that you have lots of "if-function 'do with all the ID's and then you give each ID a text. But that's not good.
I've decided to make a simple list.
if you want I can show you my solution for the simple list
ps.: I use Sencha Touch 1.1
Update:
NotesApp.views.NaviList = new Ext.List({
fullscreen: true,
flex: 1,
layout: 'card',
scroll: false,
useToolbar: false,
itemTpl: '{text}',
store: store,
listeners: {
itemtap: function (obj, idx, el, e) {
var record = this.store.getAt(idx);
var tle = record.get('text');
index = record.get('index');
NotesApp.views.notesListContainer.setActiveItem(index, { type: 'slide', direction: 'left' });
}
}
}
});
description:
My App has the name: "NotesApp".
"notesListContainer" is a Container where all my List are displayed. "index" is an ID that I get from the store and the calls list.
Now when you tap on my NaviList you set a new ActiveItem in this Container.
thanks a lot for the reply. I also tried using simple list with one Ext.button(back button in case of nestedlist). On itemtap and buttonclink, i change list's content by
var t = new Ext.data.Store and list.setStore(t).
Please let me know if there is any other better option to do it.
I'm trying to implement a list filter in a text field in sencha touch. For example, I'd have a bunch of contacts, and when I typed in the field, it might filter by name. When I click the circular X button to clear the textfield, I'd like to reset the filter to filter none of the contacts.
The problem is, I can't seem to figure out a way to detect the click on the clear button. There doesn't appear to be any type of event, and I can't seem to hack in a workaround.
If anyone has any idea how to detect a textfield clearing in sencha touch, I'd be much obliged.
I've tried in safari and xcode simulator, and am using sencha touch 1.1.0. Am I missing something? Is this not an issue when it's actually a mobile app?
You can listen for tap events on clearIconContainerEl inside the text field or override the onClearIconTap method.
Ext.setup({
icon: 'icon.png',
tabletStartupScreen: 'tablet_startup.png',
phoneStartupScreen: 'phone_startup.png',
glossOnIcon: false,
onReady: function() {
var searchField = new Ext.form.Search({
name : 'search',
placeHolder: 'Search',
useClearIcon: true,
onClearIconTap: function() {
if (!this.disabled) {
this.setValue('');
console.log('onClearTap: Clear button tapped!');
}
}
});
var viewport = new Ext.Panel({
fullscreen: true,
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
items: [searchField]
}]
});
console.log(searchField.useClearIcon);
searchField.mon(searchField.clearIconContainerEl, {
scope: searchField,
tap: function() {
if (!this.disabled) {
console.log('clearIconContainerEl: Clear button tapped!');
}
}
});
}
});
For sencha touch 2.0 users:
If your using new mvc structure, you can use this in the controller init
this.control({
'#yourTextFieldId clearicon': {
tap: function(){console.log('ClearICON tapped');}
}
....
)};
The problem is the little X is not added in by sencha touch. It is a feature of the "search" input with html5. To capture this event you need to look for the search event. How I solved this was I edited sencha-touch.js
I modified -
if (this.fieldEl) {
this.mon(this.fieldEl, {
focus: this.onFocus,
blur: this.onBlur,
keyup: this.onKeyUp,
paste: this.updateClearIconVisibility,
mousedown: this.onBeforeFocus,
scope: this
});
to be -
if (this.fieldEl) {
this.mon(this.fieldEl, {
focus: this.onFocus,
blur: this.onBlur,
keyup: this.onKeyUp,
paste: this.updateClearIconVisibility,
mousedown: this.onBeforeFocus,
search: this.onSearch,
scope: this
});
inside of Ext.form.Text = Ext.extend(Ext.form.Field, { ...
Now in my implementation of the searchfield I can make a function called onSearch which will be called when the "search" event is called. Note that the "search" event is not only called for the X but for some things like the enter key. The bottom line is sencha touch 1.1 does not check for this event at all and it is the only time the X fires an event so the only solution is to modify sencha-touch.js.
