ExtJS 6. grid checkbox model with suppressed events

I have a grid with thousands of records. It works almost fine. When I programmatically call this method:
selectionModel.selectAll(true);
it works great. My script is not freezed, because of this true parameter, which according to docs suppresses any select events. However, when I select all records via a header checkbox (which selects and deselects all records), my script gets freezed. I guess, it is because by default select events are not suppressed. I tried to find a config, which globally supresses select events, but could not find it. So, my question is how can I fix this issue? How can I globally suppress select events in my grid selModel?

You can handle using overriding onHeaderClick method of grid CheckboxModel.
In this Fiddle, I have created a demo using same method onHeaderClick.
CODE SNIPPET
Ext.application({
name: 'Fiddle',
launch: function () {
var store = Ext.create('Ext.data.Store', {
fields: ['number'],
data: (() => {
let data = [];
for (let i = 1; i <= 50000; i++) {
data.push({
'number': i
})
}
return data;
})()
});
Ext.create('Ext.grid.Panel', {
title: 'Demo',
store: store,
itemId: 'demogrid',
columns: [{
text: 'Number',
flex: 1,
dataIndex: 'number'
}],
height: window.innerHeight,
renderTo: Ext.getBody(),
selModel: {
checkOnly: false,
mode: 'SIMPLE',
onHeaderClick: function (headerCt, header, e) {
var me = this,
store = me.store,
isChecked, records, i, len,
selections, selection;
if (me.showHeaderCheckbox !== false && header === me.column && me.mode !== 'SINGLE') {
e.stopEvent();
isChecked = header.el.hasCls(Ext.baseCSSPrefix + 'grid-hd-checker-on');
if (isChecked) {
console.time();
me.deselectAll(true);
console.timeEnd();
} else {
console.time();
me.selectAll(true);
console.timeEnd();
}
}
}
},
selType: 'checkboxmodel',
buttons: [{
text: 'Select All',
handler: function (btn) {
var grid = btn.up('#demogrid');
console.time();
grid.getSelectionModel().selectAll(true);
console.timeEnd();
}
}, {
text: 'Deselect All',
handler: function (btn) {
var grid = btn.up('#demogrid');
console.time()
grid.getSelectionModel().deselectAll(true);
console.timeEnd();
}
}]
});
}
});

use suspendEvents function on model to stop all events and after you done you can start all events by resumeEvents
grid.getSelectionModel().suspendEvents();
grid.getSelectionModel().resumeEvents();

EXT JS: How to hide the fourth tab of the item based on some if condition?

I am new to ext js and I am trying to hide the fourth tab on my screen based on certain entity condition. As, I have coded I am able to disable
(blur) the 4th Setting tab, but the hidden or hide() function is failing.
Basically, I want to hide the fourth tab in items Payment.PaymentSettingsCfg on certain condition.
Any help would really appreciate, thanks in advance.
var bsdataloded = false;
Payment.PaymentSettingsCfg = {
id: 'PaymentSettingsPanel',
title: getMsg('PaymentAdmin', 'PaymentSettingsHeader'),
xtype: 'PaymentSettingsPanels',
listeners: {
activate: function() {
if (!bsdataloded) {
this.loadSettings();
bsdataloded = true;
}
}
}
}
var hidePaymentSettingcfg = false;
debugger;
if (Payment.EntitySettings &&
Payment.EntSettings["EntSITE|Payment_SWitch"] === "Y") {
Payment.PaymentSettingsCfg.disabled = true; //working
// Payment.PaymentSettingsCfg.hidden = true;// not working, even hide() not working
hidePaymentSettingcfg = true;
}
init: function() {
Ext.QuickTips.init();
Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
expires: null
}));
app = new Payment.admin.AppContainer({
id: 'main-panel',
title: Payment.getMsg('PaymentAdmin', 'PaymentConfHeader'),
el: 'bodydiv',
border: true,
layout: 'fit',
defaults: {
border: false
},
items: [{
xtype: 'tabpanel',
activeTab: 0,
width: 500,
deferredRender: false,
hidden: false,
defaults: {
border: false
},
items: [
Payment.PaymentItemCfg,
Payment.PaymentPeriodCfg,
Payment.PaymentTypeCfg,
Payment.PaymentSettingsCfg
]
}]
});
app.render();
}
};
}();

Here is the example to hide and show the tab based on if condition
i am hiding and showing the tab on checkbox checking but you can get your idea
i hope it will help you
here is the Fiddle...

Added the logic to the listeners and it worked.
listeners : {
afterrender : function(){
var testTab = this.getTabEl(3);
if (Payment.EntSettings["EntSITE|Payment_SWitch"] === "Y") {
testTab.hide();
}
}
}

Unable to create a delete button in Meteor using reactive-table

I building a sortable table in Meteor with Reactive-Table and having trouble getting my delete button to work for removing entries from the table.
Please see my javascript code below:
Movies = new Meteor.Collection("movies");
if (Meteor.isClient) {
Template.body.events({
"submit .new-movie": function (event) {
var title = event.target.title.value;
var year = event.target.year.value;
var genre = event.target.genre.value;
Movies.insert({
title: title,
year: year,
genre: genre
});
event.target.title.value = "";
event.target.year.value = "";
event.target.genre.value = "0";
return false;
}
});
Template.moviestable.events({
"click .deletebtn": function (event) {
Movies.remove(this._id);
}
});
Template.moviestable.helpers({
movies : function () {
return Movies.find();
},
tableSettings : function () {
return {
showFilter: false,
fields: [
{ key: 'title', label: 'Movie Title' },
{ key: 'year', label: 'Release Year' },
{ key: 'genre', label: 'Genre' },
{ key: 'edit', label: 'Edit', fn: function () { return new Spacebars.SafeString('<button type="button" class="editbtn">Edit</button>') } },
{ key: 'delete', label: 'Delete', fn: function () { return new Spacebars.SafeString('<button type="button" class="deletebtn">Delete</button>') } }
]
}
}
});
}
Can anyone tell me what I'm doing wrong?

In the reactive tables docs, there's an example of how to delete rows from the table. Adapting the example in the docs for your needs, your event should look like this:
Template.moviestable.events({
'click .reactive-table tbody tr': function (event) {
event.preventDefault();
var objToDelete = this;
// checks if the actual clicked element has the class `deletebtn `
if (event.target.className == "deletebtn") {
Movies.remove(objToDelete._id)
}
}
});
The problem you are having is that you are trying to find the _id property on the button click instead of the row click.
If you do console.log(this) on your button click event (as you have it in your question above) you will get something like this Object {key: "delete", label: "", fieldId: "2", sortOrder: ReactiveVar, sortDirection: ReactiveVar} which does not contain the property _id
It is easier to register the row click, where the row object is the actual document you are trying to delete, and then check if the event's target has the delete class you added.

w2ui - toolbar change button image on click

I am using w2ui. I have a toolbar with one button. This button has the icon-image "icon-delete".
When I click on the button, I want it to change the icon-image to "icon-add", but my code doesn't work.
toolbar: {
items: [{
type: 'button',
id: 'hide',
caption: 'Menü',
img: 'icon-delete'
}],
onClick: function (target, data) {
if (target == 'hide') {
this.items.img('icon-add');
}
}
}

You can use toolbar.set() method to update toolbar button icon. So in your onClick event do the following:
onClick: function (target, data) {
this.set(target, { icon: 'new_icon' });
}
See more here: http://w2ui.com/web/docs/w2toolbar.set

I created a hidden button "show" with the "icon-add" image.
when the button "hide" is clicked, it get hidden and the button "show" get shown.
toolbar: {
name: 'toolbar',
items: [
{ type: 'button', id: 'hide', caption: 'Menü', img: 'icon-delete' },
{ type: 'button', id: 'show', hidden: 'true', caption: 'Menü', img: 'icon-add' }
],
onClick: function (target, data) {
if (target == 'hide' ) {w2ui['layout'].toggle('left', window.instant);
this.hide('hide');
this.show('show');
}
if (target == 'show' ) {w2ui['layout'].toggle('left', window.instant);
this.hide('show');
this.show('hide');
}
}
}

I think you were missing the refresh line in your original approach. Here is an example that worked for me. I added an else part
if (event.target == 'hide') {
if (this.items[0].icon == 'icon-delete') {
this.items[0].icon = 'icon-add';
//do something code
} else {
this.items[0].icon = 'icon-delete';
//do something else code
}
w2ui['toolbar'].refresh('hide');
}

How to get Ext JS component from DOM element

Trying to create an inline edit form.
I have a form that looks like this:
var editPic = "<img src='https://s3.amazonaws.com/bzimages/pencil.png' alt='edit' height='24' width='24' style='margin-left: 10px;'/>";
var submitPic = "<img id='submitPic' src='https://s3.amazonaws.com/bzimages/submitPic.png' alt='edit' height='24' width='24'/>";
Ext.define('BM.view.test.Edit', {
extend: 'Ext.form.Panel',
alias: 'widget.test-edit',
layout: 'anchor',
title: 'Edit Test',
defaultType: 'displayfield',
items: [
{name: 'id', hidden: true},
{
name: 'name',
fieldLabel: 'Name',
afterSubTpl: editPic,
cls: 'editable'
},
{
name: 'nameEdit',
fieldLabel: 'Name',
xtype: 'textfield',
hidden: true,
cls: 'editMode',
allowBlank: false,
afterSubTpl: submitPic
}
]
});
The controller looks like this (a lot of events):
init: function() {
this.control({
'test-edit > displayfield': {
afterrender: this.showEditable
},
'test-edit': {
afterrender: this.formRendered
},
'test-edit > field[cls=editMode]': {
specialkey: this.editField,
blur: this.outOfFocus
}
});
},
outOfFocus: function(field, event) {
console.log('Lost focus');
this.revertToDisplayField(field);
},
revertToDisplayField: function(field) {
field.previousNode().show();
field.hide();
},
formRendered: function(form) {
Ext.get('submitPic').on('click', function (event, object) {
var field = Ext.get(object).parent().parent().parent().parent();
var cmp = Ext.ComponentQuery.query('test-edit > field[cls=editMode]');
});
},
editField: function(field, e) {
var value = field.value;
if (e.getKey() === e.ENTER) {
if (!field.allowBlank && Ext.isEmpty(value)){
console.log('Not permitted!');
} else {
var record = Ext.ComponentQuery.query('test-edit')[0].getForm().getRecord();
Ext.Ajax.request({
url: '../webapp/tests/update',
method:'Post',
params: {
id: record.getId(),
fieldName: field.name,
fieldValue: field.value
},
store: record.store,
success: function(response, t){
field.previousNode().setValue(value);
t.store.reload();
var text = response.responseText;
// process server response here
console.log('Update successful!');
}
});
}
this.revertToDisplayField(field);
} else if (e.getKey() === e.ESC) {
console.log('gave up');
this.revertToDisplayField(field);
}
},
showEditable: function(df) {
df.getEl().on("click", handleClick, this, df);
function handleClick(e, t, df){
e.preventDefault();
var editable = df.nextNode();
editable.setValue(df.getValue());
editable.show();
editable.focus();
df.hide();
}
},
I'm using the 'afterSubTpl' config to add the edit icon, and the accept icon.
I have listeners set up to listen on click events concerning them, but after they are clicked, I only have the element created by Ext.get('submitPic'). Now I want to have access to the the Ext field and form that surround it. The parent method only brings back other DOM elements. How do I connect between them? You can see what I tried in formRendered.
I hope someone can clarify this little bit for me.

Walk up the DOM tree until you find a component for the element's id:
getCmpFromEl = function(el) {
var body = Ext.getBody();
var cmp;
do {
cmp = Ext.getCmp(el.id);
el = el.parentNode;
} while (!cmp && el !== body);
return cmp;
}
Ext.Component.from(el) does exactly this since ExtJS 6.5.0, as I just learnt. Doc
Source

You can get the component by id, but only if your component and its dom element have the same id (they usually do):
Ext.getCmp(yourelement.id)
But this is not exactly good practice -- it would be better to set up your listeners so that the handler methods already have a reference to the component. For example, in your 'submitPic' component, you could define the click listener like this:
var me = this;
me.on({
click: function(arguments){
var cmp = me;
...
});
