Is there any way to set the width of an ExtJS (version 4) ComboBox's dropdown menu to be wider than that of the actual input box?
I have a comboxbox that i want to be around 200px but I have paging on the results dropdown and that width is not even big enough to show all the paging bar's controls.
Here's my code to create the combo:
var add_combo = Ext.create('Ext.form.field.ComboBox',
{
id : 'gbl_add_combo',
store : Ext.create('Ext.data.Store',
{
remoteFilter : true,
fields : ['gb_id', 'title'],
proxy :
{
type : 'ajax',
url : 'index.php/store/get_items',
reader :
{
type : 'json',
root : 'records',
totalProperty : 'total',
successProperty : 'success'
},
actionMethods :
{
read : 'POST',
create : 'POST',
update : 'POST',
destroy : 'POST'
}
}
}),
listConfig:
{
loadingText: 'Searching...',
emptyText: 'No results found'
},
queryMode : 'remote',
hideLabel : true,
displayField : 'title',
valueField : 'gb_id',
typeAhead : true,
hideTrigger : true,
emptyText : 'Start typing...',
selectOnFocus : true,
width : 225,
minChars : 3,
cls : 'header_combo',
pageSize : 15
});
There are two parts to this. Firstly, you need to set matchFieldWidth: false in your combobox config. You can then specify width attributes in the listConfig section to style just the dropdown, while specifying the width of the combobox itself in the main config.
This varies from the pervious version, which just let you specify the listWidth property.
I didn't find way to change 'matchFieldWidth' property dynamically. So I found another solution:
{
xtype: 'combobox',
fieldLabel: 'Short Options',
queryMode: 'local',
store: ['Yes', 'No', 'Maybe'],
matchFieldWidth: false,
listConfig: {
listeners: {
beforeshow: function(picker) {
picker.minWidth = picker.up('combobox').getSize().width;
}
}
}
}

In ExtJS 7+ modern, you need to use the beforepickercreate event if you wish to control the width of the combobox's picker.
It's not very intuitive, but it works.
xtype: 'combobox',
...
listeners: {
beforepickercreate: {
fn: function(cmp, newV) {
newV.listeners = {
beforeshow: function(cmp) {
cmp.setMinWidth(400);
cmp.setWidth(400);
}
}
return newV;
}
}
}

I'm trying to invoke headerclick event using ext js listener but unable to invoke.
here is my code:
var myGrid = Ext.Create('Ext.grid.Panel', {
renderTo: 'shrGrid',
renderTo: myGrid,
store: myStore, //JSON object
columns: myGrid.columns, //JSON object
viewConfig: {
listeners: {
cellclick: function (view, cell, cellIndex, record, row, rowIndex, e) {
alert("cell clicked");
},
headerclick function (shrGrid, columns , e, t, eOpts) {
alert("header clicked");
}
}
}
});
Here the cellclick is being invoked without any issue.
but headerclick is neither being invoked neither nor giving any error.
I just used headerclick here only. pls help me I missed anything or give me some example link.
Your myGrid.columns probably looks something like this:
columns : [{
header : 'Name',
dataIndex : 'name',
sortable : false,
field : {
allowBlank : false
}
}, {
id: 'headerid', //Set your id here
header : 'Description',
dataIndex : 'description',
sortable : false,
field : {}
}, {
header : 'Order',
width : 40,
dataIndex : 'sortOrder',
hidden : true
}, {
header : '',
dataIndex : 'id',
width : 30,
fixed : true,
sortable : false,
hideable : false,
align : 'center',
renderer : function (v, p, r) {
return "<img alt='Delete this record' src='images/icons/delete.gif'>";
}
}],
If you do that you can access the id and add a listener like this
var myGrid = Ext.Create('Ext.grid.Panel', {
renderTo: 'shrGrid',
renderTo: myGrid,
store: myStore, //JSON object
columns: myGrid.columns, //JSON object
viewConfig: {
listeners: {
render: function(component) {
Ext.get('headerid').on('click',function() { //reference the id you defined for the column header
alert('header clicked');
});
}
}
}
});
I have an ExtJS window that has 2 separate panels with checkboxgroups. They both show the same values, but user cannot select the same item from both checkboxgroups.
I want to deal with this a little fancier than just checking and alerting a warning in both ckeckboxgroup's listeners when user selects already selected value in another checkboxgroup.
To avoid alerts, I want to either hide or disable the box.
I have tried to add hidden:true or disabled:true but no luck:
Ext.create('widget.window',
{
title : 'Select a value',
draggable : true,
modal : true,
closable : true,
closeAction : 'destroy',
width : 400,
height : 350,
layout:
{
type : 'hbox',
align : 'stretch'
},
items :
[{
xtype : 'panel',
title : 'Success',
autoScroll : true,
flex : 1,
items :
[{
xtype : 'checkboxgroup',
itemId : 'success',
columns : 1,
vertical : true,
items : yes_checkbox,
listeners :
{
change: function(field, newValue, oldValue, eOpts)
{
// newValue.rb
}
}
}]
},
{
xtype : 'panel',
id : 'panel_failure',
title : 'failure',
autoScroll : true,
flex : 1,
items :
[{
xtype : 'checkboxgroup',
itemId : 'failure',
columns : 1,
vertical : true,
items : no_checkbox,
listeners :
{
change: function(field, newValue, oldValue, eOpts)
{
// newValue.rb
}
}
}],
}],
});
I tried to get the panel_failed like Ext.getCmp('panel_failed').items.add(//something here) inside the change listener. But I cannot figure out whether the add() is the right method, and if is, what is the format to write inside the function.
Thanks
You can define itemId of all your checkboxes and then will be easy to select and disable them with setDisabled(true);
I want to add client side validation for file upload using HTML5 "accept" attribute and ExtJs "inputAttrTpl" config.
My ExtJs code is following (ExtJs 4.1):
{
xtype : 'filefield',
action : 'upload',
name : 'file',
inputAttrTpl: 'accept="image/*"',
hideLabel : true,
buttonOnly : true,
anchor : '100%',
buttonText : 'Upload img...',
margin: 5
}
But when I am checking file field in firebug, it doesn't contain "accept" attribute.
Can you suggest some solutions for this issue?
Thanks for your replies.
{
xtype:'filefield',
listeners:{
afterrender:function(cmp){
cmp.fileInputEl.set({
accept:'audio/*'
});
}
}
}
You can set accept to "" to remove the restriction.
Fiddle
{
xtype: 'fileuploadfield',
name: 'file',
fieldLabel: 'Photo',
labelWidth: 50,
allowBlank: false,
buttonText: 'SelectPhoto',
anchor: '100%',
reset: function () {
var me = this,
clear = me.clearOnSubmit;
if (me.rendered) {
me.button.reset(clear);
me.fileInputEl = me.button.fileInputEl;
me.fileInputEl.set({
accept: 'image/*'
});
if (clear) {
me.inputEl.dom.value = '';
}
me.callParent();
}},
listeners:{
change: 'fileInputChange',
afterrender:function(cmp){
cmp.fileInputEl.set({
accept:'image/*'
});
}
},
regex: /(.)+((\.png)|(\.jpg)|(\.jpeg)(\w)?)$/i,
regexText: 'Only PNG and JPEG image formats are accepted'
}
Ext js combo is not working in IE7. I need this combo act like textbox with virtual combo (like google search). It is working in IE9 and FF but not in IE7
This is my code:
SearchIncidentForm=new Ext.FormPanel ({
border:false,
renderTo:'searchIncidentDiv',
id: 'searchIncidentForm',
items : [{
xtype:'panel',
id :'panelsearchIncident',
layout:'column',
defaults:{
columnWidth:0.50,
labelAlign : 'top',
layout:'form',
border:false,
bodyStyle:'margin-top:5px; '
},
border:false,
items : [{
defaults:{anchor:'100%'},
items:[{
id : "incidentId",
fieldLabel : 'Incident Id',
labelStyle: 'color: #6C6C6C;width:85px;padding-top:7px;height: 22px;',
xtype : 'combo',
store:incidentStores,
//style: 'width:85px;height: 18px;',
width:100,
allowBlank : false,
labelAlign: 'top',
displayField : 'incidentId',
valueField : 'incidentId',
selectOnFocus : true,
typeAhead : false,
mode : 'remote',
triggerAction : 'all',
editable: true,
msgTarget:'qtip',
listAlign : 'tl-bl?',
//anchor : '80%',
minChars : 1,
hideTrigger:true,
hiddenName: 'incidentId',
listWidth:100,
listHeight:50,
submittValue:true,
listeners : {
specialkey : function(field, e){
var key=e.getKey();
if (key==e.ENTER) {
incidentSearchButtonHandler();
}
},
beforequery : function(){
var val=Ext.getCmp('incidentId').getValue();
if(isNaN(this.getEl().dom.value)){
Ext.Msg.alert("","Please type numeric value");
}
else{
Ext.getCmp('incidentId').getStore().proxy.setUrl('getIncidentId.html?&query='+this.getEl().dom.value);
}
}
}
}]
},{
items:[{
xtype : 'button',
text : 'Search',
style: 'margin-top:19px;margin-left:20px;width:50px;',
width: 35,
height:15,
handler : incidentSearchButtonHandler
}]
}]
}]
});
}
but it's not working in IE. When I press Search button, an alert is shown that please type Id. That means it doesn't take the value that has been typed. Please help.
I've been bitten by this before with IE: you have an extra comma after the last element of your array:
items:[{
submittValue:true,
listeners : {
specialkey : function(field, e){
var key=e.getKey();
if (key==e.ENTER) {
incidentSearchButtonHandler();
}
}, // <------ Extra comma. Delete it.

I am building a login window with ExtJs, using the following code :
Ext.define('DTL.view.windows.LoginWindow', {
extend : 'Ext.window.Window',
alias : 'widget.login',
id : 'loginWindow',
autoShow : true,
width : 400,
height : 180,
layout : 'border',
border : false,
modal : true,
closable : false,
resizable : false,
draggable : false,
initComponent : function () {
this.items = [{
region : 'north',
height : 52,
bodyCls : 'app_header'
}, {
id : 'login_form',
region : 'center',
xtype : 'form',
bodyStyle : 'padding:10px; background: transparent;border-top: 0px none;',
labelWidth : 75,
defaultType : 'textfield',
items : [{
fieldLabel : 'Username',
name : 'username',
id : 'usr',
allowBlank : false
}, {
fieldLabel : 'Password',
name : 'password',
inputType : 'password',
id : 'pwd',
allowBlank : false
}
]
}
];
this.buttons = [{
id : 'login_button',
text : 'Login',
disabled : true
}
];
this.callParent(arguments);
}
});
Now everything looks fine, except the fact that the password field has no borders.
I tried various code modifications, but nothing helped.
Does anyone have an idea to fix this?
I am using ExtJs 4.0.7
EDIT :
I made another interesting discovery. If I add a third textfield the bug will move to that one.
Apparently it affects always the last textfield.
The problem is caused by how you create the window. See this Sencha forum post:
Textfield Border Problem
i.e. you need to use Ext.create('DTL.view.windows.LoginWindow'); rather than xtype: 'login'
