I have an application which has to be screen readable (for blind people) and I'm struggling to read a FontAwesome Icon. Right now I have this for example:
{
xtype: 'actioncolumn',
items: [
{
iconCls: 'x-fa fa-envelope',
}],
dataIndex: 'edit',
text: 'Send E-Mail'
}
And I use NVDA Screen reader -> https://www.nvaccess.org/download/
However it cannot read this text ("Send E-Mail") on mouse hover. I know that font-awesome has option to include aria-label="Send E-Mail" but how can I apply it to ExtJS item?
Have you tried this:
{
iconCls: 'x-fa fa-envelope',
tooltip: 'Send E-Mail',
}
I wasn't able to find a way to make the "actioncolumn" compliant, so I have converted them to a "widgetcolumn" and that works better. The downsides to this is that you cannot have multiple "widgets" in one column, so each of actions will get its own column and you have buttons in the columns instead of the more elegant icons. But, what can you do, Ext....
{
xtype: 'widgetcolumn',
text: 'Edit', //column header
align: 'center',
width: 60,
widget: {
xtype: 'button',
width: 40,
iconCls: 'x-fa fa-pencil',
ariaLabel: 'click to edit',
handler: 'edit'
}
}
For the handler, the arguments are a little different since it's now a button (this is specific to my case, using the record id):
edit: function(button) {
var grid = button.up('grid'),
store = grid.getStore(),
recordId = button.getWidgetRecord().getId(),
record = store.findRecord('id', recordId);
//and so on....
}

I have an ExtJS 6.2 modern app. What is the proper way to add a button to a grid cell?
I tried using the column renderer fn to return a button but I just see the HTML tags rendered, not the actual element. I also tried using the "widgetcell" component which does render the button but not the button text.
Fiddle.
Using your fiddle as an example, you can make a widget button like this
columns: [
//other columns
{
dataIndex: 'description',
flex: 1,
cell: {
xtype: "widgetcell",
widget: {
xtype: "button",
}
}
}
]
You can do it without widgetcell by:
{
text: "Button Widget ",
flex: 1,
cell: {
xtype: 'button',
text: 'CLICK ME'
}
}
Or with panel
{
text: "Button Widget ",
flex: 1,
cell: {
xtype: "widgetcell",
widget: {
xtype: 'panel',
header: false,
items: [{
xtype: 'button',
text: 'CLICK ME'
}]
}
}
}
I wanted to accomplish the same task but thought I would include a little more complete example. This was the first resource I came across so figured I should post here.
So for my problem I just wanted to pass the data and render a view utilizing that data.To do that I add a column to my grid and added a widgetcell inside that column. The grid column requires a dataIndex but my button wasn't associated with a specific column in my model, so I just added a non-existent column for the required value which worked.
After that you can specify a widget object as a cell config. You can add a handler key and access the record object from the grid like below.
{
xtype: 'gridcolumn',
flex: 1,
width: 80,
dataIndex: 'button',
text: 'Details',
cell: {
xtype: 'widgetcell',
widget: {
xtype: 'button',
text: 'View',
width: '100%',
handler: function(button,e){
let accountData = this.up().up()._record.data
console.log(accountData);}
}
}
}
I can add my own button to the built-in tools "Help" etc on the panel header:
tools:[
{
type:'help',
tooltip: 'Get Help',
handler: function(event, toolEl, panel){
// show help here
}
}],
header: {
layout: {
type: 'hbox',
align: 'right'
},
items: [{
xtype: 'button',
text: 'test'
}]
} ...
but button 'test' appears far left before the panel title ... header layout hbox right obviously not the way to do it :-). Button 'test' just a placeholder - I want to eventually add a menu button - so another css tool would not work - is there a simple way of doing this or do I need to use dom element positiong etc? tia.
If you're using ExtJS 4.2, you can use the titlePosition property to accomplish this. See http://jsfiddle.net/U8MSd/
tools: [{
type: 'help',
tooltip: 'Get Help',
handler: function (event, toolEl, panel) {
// show help here
}
}],
header: {
titlePosition: 0,
items: [{
xtype: 'button',
text: 'test'
}]
}
i define a treeGrid with plugin CellEditing like
Ext.define('MyExample', {
extend: 'Ext.tree.Panel',
id: 'example',
alias: 'example',
....
plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1,
listeners: {
beforeedit: function(plugin, edit){
alert('don't run second time');
}
}
})
],
...
And i have a button when i click this button will call below window (this window has treeGrid above)
Ext.create('Ext.window.Window', {
title: 'Phân xử lý',
modal:true,
height: 500
width: 500
layout: 'border',
...
item[
{
title: 'example',
region: 'center',
xtype: 'example', // that here
layout: 'fit'
}
]
Everything working at first time but when i close the window at first time and click button to call window again then CellEditting still working but listeners not working ?
How to fix that thanks
EDIT
Please see my example code in http://jsfiddle.net/E6Uss/
In first time when i click button. Everything working well like
But when i close Example window and open it again I try click to blocked cell again i get a bug like
How to fix this bug? thanks
The problem here is that you are using Ext.create inside the plugins array for the tree grid. This have the effect of creating it once and attaching the result adhoc to your defined class.
If you close the window, all the resources within the window are destroyed. The second time you instantiate the tree panel, the plugin is not there. Take a look at this fiddle : I see what your issue is. Take a look at http://jsfiddle.net/jdflores/E6Uss/1/
{
ptype : 'cellediting',
clicksToEdit: 1,
listeners: {
beforeedit: function(plugin, edit){
console.log('EDITOR');
if (edit.record.get('block')) {
alert('this cell have been blocked');
return false;
}
}
}
}
You're recreating the window on every click of the button. This recreation may be messing with your configuration objects or destroying associations or references within them, or something similar. Try to reuse the window everytime by replacing your button code with something like:
Ext.create('Ext.Button', {
text: 'Click me',
visible: false,
renderTo: Ext.getBody(),
handler: function(button) {
if(!button.myWindow)
{
button.myWindow = Ext.create('Ext.window.Window', {
title: 'Example',
height : 300,
width : 500,
layout: 'border',
closeAction: 'hide',
items: [{
region: 'center',
floatable:false,
layout:'fit',
xtype: 'example',
margins:'1 1 1 1'
}
]
});
}
button.myWindow.show();
}
});
Maybe it needed complete the editing cell, try finish it:
...
beforeedit: function(plugin, edit){
alert('don't run second time');
plugin.completeEdit();
}

I put together a working example here: http://jsfiddle.net/jdflores/6vJZf/1/
I think the problem with your column is that it's dataIndex is expecting that the editor value be a boolean type (because 'block' was set as datIndex instead of 'date'). I assume you are using the 'block' field just to identify which are blocked to be edited. I modified the fidle provided here: http://jsfiddle.net/jdflores/6vJZf/1/
{
text: 'Block Date',
dataIndex: 'date',
xtype: 'datecolumn',
format: 'd/m/Y',
editor: {
xtype: 'datefield',
allowBlank: true,
format: 'd/m/Y'
}
}
I have a formPanel set up with a text field. When a button is pressed, I would like it to change the disabled property of the text field from true to false, allowing it to be editable. The problem is that I don't know how to make this stick. Here's the form code:
myApp.views.formContainer = new Ext.form.FormPanel({
id: 'inspectionForm',
layout: 'vbox',
width: '100%',
items: [{
xtype: 'textfield',
name: 'myText',
id: 'myText',
label: 'License Plate',
width: '90%'
},
{
xtype: 'button',
text: 'Submit',
height: 40,
ui: 'confirm-round',
handler: function()
{
Ext.get('myText').disabled = false;
}
}]
});
The thing about Ext.get('mytext'),disabled = false; is that it works. Checking it later shows that the disabled attribute is set to false. But you still can't edit it. Does anyone know how to do this?
By calling Ext.getCmp('mytext').disabled = false; you only change the initial config property. To actually modify the component use Ext.getCmp('mytext').enable(); and Ext.getCmp('mytext').disable();
For making a toolbox, I want to know how to make a radiogroup with regular buttons and not radiobuttons in latest extJS
Like this with jQueryUI: http://jqueryui.com/demos/button/#radio
Thanks in advance,

I think you should look at using a set standard ExtJS buttons. A button can be assigned to a group so that they act as the elements shown in your link.
See this example:
{
xtype: 'button',
text: 'Choice 1',
toggleGroup: 'mygroup'
}, {
xtype: 'button',
text: 'Choice 2',
toggleGroup: 'mygroup'
}, {
xtype: 'button',
text: 'Choice 3',
toggleGroup: 'mygroup'
}
Buttons also have a property called enableToggle, that allows them to toggle, and is automatically set to true when you set a toggleGroup, and toggleGroup tells ExtJS how they are related.
Note, they look like regular ExtJS buttons, but behave like you want.
There is a less complicated (better?) way to disallow deselecting a button. Set the allowDepress config option to false:
{
xtype: 'radiogroup',
layout: 'hbox',
defaultType: 'button',
defaults: {
enableToggle: true,
toggleGroup: 'mygroup',
allowDepress: false,
items: [
{ text: 'Choice 1'},
{ text: 'Choice 2'},
{ text: 'Choice 3'}
]
}
}
Just to answer #mastak's comment (in the answer above), in order to disallow the action of de-selecting a button, add this listener to each button:
listeners: {
click: function(me, event) {
// make sure a button cannot be de-selected
me.toggle(true);
}
}
That way, each click on a button will re-select it.
-DBG
Just adding to the #deebugger post. You can also use the following button property to not allow to deselect a selection
Ext.create('Ext.Button', {
renderTo : Ext.getBody(),
text : 'Click Me',
enableToggle : true,
allowDepress : false
});
