extjs5 widgetcolumn multiple widgets in a single cell - javascript

I create a widgetcolumn as the panel in which several components. How can i link record parameters with these components?
For example:
{
xtype: 'widgetcolumn',
dataIndex: 'data',
widget: {
xtype: 'panel',
height: 77,
width: 642,
layout: {
type: 'vbox',
align: 'stretch'
},
items: [
{
xtype: 'button',
text: record.get('name') //<<-- how can i link this record from the grid with this component?
},
{
xtype: 'button',
text: record.get('type') //<<-- how can i link this record from the grid with this component?
},
{
xtype: 'button',
text: record.get('location') //<<-- how can i link this record from the grid with this component?
}
]
}
}
I have a following store:
var store = Ext.create('Ext.data.Store', {
fields:['name', 'type', 'location'],
data:[
{name: 'name1', type: 'type1', location: 'loc1'},
{name: 'name2', type: 'type2', location: 'loc2'}
]
});
Maybe, I can get access to the record via renderer function? Something like this:
renderer: function(value, meta, record) {
//How can I get access to widget instance?
}

I solved this problem. We need to get access to the parent element - widgetcolumn, and then call the function - getWidgetRecord.
{
xtype: 'label',
text: 'Some text...',
cls: 'gridcall-label-asgmt',
listeners: {
resize: function(label) {
var parent = label.up();
while(typeof parent.up() !== 'undefined') {
parent = parent.up();
} // --- while
var record = parent.getWidgetRecord();
if (typeof record === 'undefined') return;
label.setText(record.data.asgmt, false);
} // --- resize
} // --- listeners
}

Ext JS: tpl config is ignoring html in Panel

I need to use both of configs tpl and html within panel class but it's not let to render both configs.
How can be able to use both?
Ext.define('InfoCard.Main', {
extend: 'Ext.panel.Panel',
viewModel: {
type: 'infocardvm'
},
layout: {
type: 'table'
},
items: [{
xtype: 'infocard',
userCls: 'totalReCls',
bind: {
html: '{totalReBar}'
}, //Can't use 'tpl' here because it doesn't have setTpl()
glyph: 'xf015#FontAwesome',
// tpl: 'TotalReBar' //When I'm uncomment the config, then ignores 'bind: html'
}]
});
Here is full sample FIDDLE.
Question is related with this post at Software Engineering site.
You can use displayfield inside of items of panel. In display field have methods for setValue() and setFieldLabel(). So you can change on basis of requirement.
In this FIDDLE, I have created a demo using your code and put modification. Hope this will help/guide you to achieve your requirement.
CODE SNIPPET
Ext.define('InfoCard.Main', {
extend: 'Ext.panel.Panel',
tbar: [{
text: 'Refresh data',
handler: function () {
var vm = this.up('panel').getViewModel(),
store = vm.getStore('firstStore');
store.getProxy().setUrl('stat1.json');
store.load();
}
}],
viewModel: {
type: 'infocardvm'
},
layout: {
type: 'table'
},
defaults: {
xtype: 'infocard',
},
items: [{
items: {
xtype: 'displayfield',
fieldLabel: 'Total ReBar',
bind: '{totalReBar}'
},
glyph: 'xf015#FontAwesome'
}, {
items: {
xtype: 'displayfield',
fieldLabel: 'Total RoBar',
bind: '{totalRoBar}'
},
bodyStyle: {
"background-color": "#DFE684"
},
glyph: 'xf015#FontAwesome'
}, {
items: {
xtype: 'displayfield',
fieldLabel: 'Total PaBar',
bind: '{totalPaBar}'
},
bodyStyle: {
"background-color": "#fbe3ab"
},
glyph: 'xf015#FontAwesome'
}]
});
When I understand you correctly you want to render a static string with a variable value.
{
xtype: 'infocard',
bind: { data: '{totalReBar}' }, // bind the data for the tpl
tpl: 'TotalReBar {totalCount}' // use the data provided via binding in the tpl
}
The formula now has to return an object for the tpl data binding.
You can access the values in the tpl via the key's.
formulas: {
totalReBar: {
bind: {bindTo: '{firstStore}', deep: true},
get: function (store) {
var record = store.findRecord("code", "TOTALRE");
return {
totalCount: record ? record.get("totalcount") : "-1" // totalCount is now available in the tpl as a variable
};
}
},
See the modified fiddle.
I believe that what you want is this:
{
xtype: 'infocard',
userCls: 'totalReCls',
bind: {data: {'myVal': '{totalReBar}'}},
glyph: 'xf015#FontAwesome',
tpl: '{myVal}'
}
hope that helps

ExtJS 5 Uncaught TypeError: cannot read property 'parentNode' of null in Tab Panel

I am using ExtJS version 5.1.0.
Problem: I have a Ext.panel.Panel in my view. In this panel's beforeRender, I am trying to add an xtype:'form' whose items contain a tabpanel with multiple tabs.
When I switch the tab after some seconds of waiting on other tab, I get this exception
Uncaught TypeError: cannot read property 'parentNode' of null
And as a result of this, entire view of the switched tab is lost(its blank).
I have been trying this for a time now, but unable to find a solution.
Any suggestions on this would be a great help.
Here is my code snippet:
Ext.define({
'myClass',
extend: 'Ext.panel.Panel',
layout: 'fit',
viewModel: {
type: 'abc'
},
beforeRender: function() {
var me = this;
me.add({
xtype: 'form',
trackResetOnLoad: 'true',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [
me.getContainer()
]
});
},
getContainer: function() {
var me = this;
var tabpanel = Ext.create({
'Ext.TabPanel',
allowDestroy: false,
reference: 'abc', //being used in application somewhere
layout: 'fit',
border: 0,
activeTab: 0,
items: [{
xtype: 'container',
bind: {
data: {
abcd
}
},
title: 'tab1',
layout: 'fit',
items: [
me.createContainer1() // contains form fields
]
},
{
xtype: 'container',
title: 'tab2',
layout: 'fit',
bind: {
data: {
abcf
}
},
items: [
me.createContainer2() // contains form fields
]
}
]
});
}
});
This is not a duplicate, it is a issue related to tabpanel and not simple HTML. It uses framework related knowledge. If anyone has idea about this, then please explain.
Firstly you need to use beforerender event instead of beforeRender and beforerender will be inside of listeners.
And also you can return directly xtype instead of creating like below example
createField: function() {
return [{
xtype: 'textfield',
emptyText: 'Enter the value',
fieldLabel: 'Test'
}];//You here return Object or Array of items
}

Extjs - How to invoke parent view controller methods from child view controller?

I added a listener onParentPagePopupCommit for button in popup which was declared in parent view controller and added the popup in view port, now the view model bindings are working as expected, but not sure how to invoke the parent view controller methods without exposing the same methods names in child view controller. Is there any way to extend View Controller during runtime in ExtJs Modern 6.5.
Fiddle
onShowChildPopup: function (sender) {
var popup = sender.up('panel').popups['childPopup'],
pageCtrler = sender.lookupController(),
pageVM = pageCtrler.getViewModel(),
page = pageCtrler.getView(),
popupCtrler = new Ext.app.ViewController({
parent: pageCtrler, //setting parent ctrler
//popup commit event on popup view controller
onPopupCommit: function () {
debugger;
Ext.Msg.alert("Popup Update", "Popup View Controller Invoked")
console.log("popup view controller - commit");
},
// this works but any other way
// same methods name on popup view ctrler...
/*onParentPagePopupCommit: function(){
debugger;
// I don't like this way of invoking a parent method
// this may introduce few more bugs if the parent gets value from its own
// view model - (this will be parent vm and not child/popup.)
// need something similar to extend inorder to reuse certain methods..
this.parent.onParentPagePopupCommit();
var vm = this.getViewModel().get('vm');
vm.set('fullName',this.getFullName());
}*/
}),
popupVM = new Ext.app.ViewModel({
parent: pageVM, //setting parent view model
links: {
//vm is not merging with parent
//vm: {
childvm: {
reference: 'ChildModel',
create: {
address: "child Address",
phone: "child Phone"
}
}
}
});
popup.controller = popupCtrler;
popup.viewModel = popupVM;
popup = Ext.create(popup);
popup.setShowAnimation({
type: 'slideIn',
duration: 325,
direction: 'up'
});
popup.setHideAnimation({
type: 'slideOut',
duration: 325,
direction: 'down'
});
popup.setCentered(true);
/* popup.on('show', function () {
debugger;
});*/
Ext.Viewport.add(popup).show();
//popup.showBy(page, "c-c");
}
For this you need to use extend config in controller.
For example:
Ext.define('Person', {
say: function(text) { alert(text); }
});
Ext.define('Developer', {
extend: 'Person',
say: function(text) { this.callParent(["print "+text]); }
});
In this FIDDLE, I have created a demo using your code and made some modification. I hope this will help or guide your to achieve you requirement.

Sencha Touch 2: Reloading a treeStore in nestedList to reflect user selection

I have a nested list in my application, and when users make a selection they are taken to a detailCard with some options. One of these options is to "confirm" their selection. Once confirmed, the selection should be removed from the list. This works on the server side, so if the app is refreshed the selection is gone. However I was hoping to remove the selection in the treeStore itself and refresh the view somehow so that users can immediately see the effect of their confirmation. I was following a tutorial for nestedList that I can't seem to find anymore, and this code is based on that:
var itemId = '';
Ext.define('MyApp.view.MainView',
{
extend: 'Ext.tab.Panel',
xtype: 'main',
alias: "widget.mainview",
requires: [
'Ext.dataview.NestedList',
'Ext.data.proxy.JsonP'
],
config:
{
tabBarPosition: 'bottom',
items: [
{
xtype: 'nestedlist',
title: 'Listings',
iconCls: 'home',
displayField: 'listingValue',
scrollable: true,
detailCard:
{
xtype: 'panel',
scrollable: true,
styleHtmlContent: true,
items: [
{
xtype: 'fieldset',
readOnly: true,
title: 'Schedule Information:',
items: [
{
name: 'from',
id: 'from',
xtype: 'textareafield',
label: 'From',
readOnly: true
},
{
name: 'to',
id: 'to',
xtype: 'textareafield',
label: 'To',
readOnly: true
},
{
name: 'moreInfo',
id: 'moreinfo',
xtype: 'textfield',
label: 'More Info',
readOnly: true
},
]
},
{
xtype: 'container',
flex: 1,
items: [
{
xtype: 'button',
text: 'Confirm',
action: 'confirmSelection',
margin: '10 5',
padding: '5',
ui: 'confirm'
}]
}]
},
listeners:
{
itemtap: function (nestedList, list, index,
element, post)
{
var detailCard = this.getDetailCard();
detailCard.setHtml('');
itemId = post.get('id');
Ext.getCmp('from').setValue(post.get(
'from'));
Ext.getCmp('to').setValue(post.get('to'));
Ext.getCmp('moreinfo').setValue(post.get(
'moreinfo'));
}
},
store:
{
type: 'tree',
fields: [
'id', 'from', 'to', 'fromcity', 'tocity',
'time', 'address',
{
name: 'leaf',
defaultValue: true
},
{
name: 'listingValue',
convert: function (value, record)
{
listingValue = '$<b>' + record.get(
'address') + '</b> ' + record
.get('fromcity') + ' to ' +
record.get('tocity');
return listingValue;
}
}
],
root:
{
leaf: false
},
proxy:
{
type: 'jsonp',
url: 'http://myURL.com/page.php?action=go',
reader:
{
type: 'json',
rootProperty: 'root'
}
}
}
},
{
title: 'Dashboard',
iconCls: 'action',
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Dashboard'
},
]
}]
}
});
I have no idea what to do at this point, because the store is set up in the view and I'm not sure how to access it in my controller. I learned about treeStore.removeAll() and treeStore.load(), but how can I call those functions in a controller when the store is set up without any type of reference name? Is there a way I can remove the user's selection and display the view, or perhaps reload the view altogether so it can retrieve the new list from the server?
Because my list is on the first page of my app, I managed to get away with window.location.reload(); and reloading the whole app. Its not the most elegant solution, but the changes are reflected.
I won't accept my own answer just yet in case someone comes along with a better solution.

Extjs fill fields inside a tabpanel with config variables

I am trying to populate a tabpanel with an extension I've created. Inside this extension i have a panel with 2 fields (timefield and datefield) which may have the values from my store.
Each of these fields may have different values in each tab. I am passing these values from the extended component via config. So far I can see these values in the console.log() but I can't put these values inside the fields.
This is how my extended component is:
Ext.define('PlaylistGrid', {
extend: 'Ext.panel.Panel',
alias: 'widget.playlistgrid',
border: false,
config: {
plIndex: 0,
plDate: '1970-10-10',
plTime: '00:00:00'
},
constructor: function(cfg) {
Ext.apply(this, cfg);
this.callParent(arguments);
},
items: [{
layout: 'hbox',
bodyStyle: 'padding: 5px',
border: false,
xtype: 'form',
name: 'myForm',
items: [{
xtype: 'datefield',
fieldLabel: 'Data de início',
name: 'datefld',
itemId: 'datefld'
}, {
xtype: 'timefield',
fieldLabel: 'Horário de início',
name: 'timefld'
}, {
xtype: 'button',
iconCls: 'save',
style: 'margin-left: 10px',
tooltip: 'Salvar data e hora',
handler: function() {
Ext.Msg.alert('Salvando...', 'Implementar');
}
}]
}, {
xtype: 'grid',
border: false,
width: '100%',
height: 476,
columns: [{
header: 'Ordem',
dataIndex: 'order',
width: 50
}, {
header: 'Video',
dataIndex: 'video',
width: 308
}, {
header: 'Duracao',
dataIndex: 'duration',
width: 100
}, {
header: 'Formato',
dataIndex: 'format',
width: 75
}]
}],
listeners: {
render: function(e, eOpts) {
console.log(e.getPlDate());
}
}
});
And this is how I am adding this component inside the tabpanel:
var plSt = Ext.getStore('playlistStore');
plSt.load();
plSt.on('load', function(store, records, successful, eOpts) {
plSt.each(function(record, idx) {
var playlist = {
xtype: 'playlistgrid',
title: 'Playlist ' + (records[idx].data.playlistId),
name: 'playlist' + idx,
plIndex: records[idx].data.playlistId,
plDate: records[idx].data.playlistDate,
plTime: records[idx].data.playlistTime
};
e.add(playlist);
});
if (records.length > 0) {
e.setActiveTab(1);
}
})
The data seems to be ok, but it does not display in the datefield... Do you have any point about it?
I have already search how to do this, but couldn't find the answer at all.
SOLVED
OK, I got it. The solution was simple. I just added a new config var that passes the current tab index, and the afterRender method.
I did this
afterRender: function(e, eOpts) {
var idx = e.getTabIdx();
var dateFld = Ext.ComponentQuery.query('datefield[name=datefld]');
dateFld[idx].setValue(new Date(e.getPlDate()));
//console.log(e.getPlDate());
}
Thank you!
