In extjs, is there any way to change a property for a specific type of control across the entire project from one place, essentially making it the default value for this property on all new instances of that class?
In particular, I want to change all the msgTarget's on all field controls from 'qtip' to 'side'.
This should work:
Ext.onReady( function() {
Ext.override( Ext.form.Labelable, {
msgTarget: 'side'
});
});
See this answer for more info.
The only thing that is working for me is something like this:
Ext.define('FooMsgTargetOverride', {
override: 'Ext.form.field.Base',
msgTarget: 'under'
});

Does anyone know here how to override the messagebox to put icons for the buttons? i.e: check icon for YES/OK, cross button for NO, etc.
I've tried to override the makeButton function of Ext.window.MessageBox but it doesn't seem to work and doesn't even hit the debugger:
Ext.override(Ext.window.MessageBox, {
makeButton: function (btnIdx) {
debugger;
var btnId = this.buttonIds[btnIdx];
return new Ext.button.Button({
handler: this.btnCallback,
itemId: btnId,
scope: this,
text: this.buttonText[btnId],
minWidth: 75,
iconCls: ['check', 'no', 'cancel', 'blah'][btnId]
});
}
});
As #scebotari66 have stated, Ext.Msg and Ext.MessageBox are singletons of Ext.window.MessageBox. So when you override Ext.window.MessageBox.makeButton, this will have no effect if you are using the singletons for this class.
However, there is a way to apply your overrides to Ext.window.MessageBox to the singleton. Guess how.
(drumroll)
tantantanan!
Ext.MessageBox = Ext.Msg = new Ext.window.MessageBox();
Yep, that's correct. You just need to re-assign the singleton after your override.
So:
Ext.override(Ext.window.MessageBox, {
makeButton: function (btnIdx) {
var btnId = this.buttonIds[btnIdx];
return new Ext.button.Button({
handler: this.btnCallback,
itemId: btnId,
scope: this,
text: this.buttonText[btnId],
iconCls: ['okbutton', 'yesbutton', 'closebutton', 'cancelbutton'][btnIdx],
minWidth: 75 //or you can also remove this to make the icons close to the label
});
}
});
//re-assign singleton to apply overrides
Ext.MessageBox = Ext.Msg = new Ext.window.MessageBox();
Next time you call Ext.Msg.alert(), your icons are now showing too.
I hope you find this helpful.
NOTE: The iconCls config should be in the order [ok, yes, no, cancel]
As you can see from the source code, the makeButton method is called from initComponent of Ext.window.MessageBox.
I assume that you are using the Ext.MessageBox (or Ext.Msg) singleton instance for displaying message boxes. This instance is created in the callback function immediately after the Ext.window.MessageBox is created (check the third argument from Ext.define). This also means that it happens before your override.
So you can directly override the buttons of the singleton instance like so:
Ext.Msg.msgButtons.ok.setIconCls(okBtnCls);
Ext.Msg.msgButtons.yes.setIconCls(yesBtnCls);
Ext.Msg.msgButtons.no.setIconCls(noBtnCls);
Ext.Msg.msgButtons.cancel.setIconCls(cancelBtnCls);
You can also rely on your makeButton override if you will show message boxes by creating a new instance of the class:
var myMsg = Ext.create('Ext.window.MessageBox', {
closeAction: 'destroy'
}).show({
title: 'Custom MessageBox Instance',
message: 'I can exist along with Ext.Msg'
});
I need to customize the yes no combo within a specific panel, local to the panel without affecting the parent yesnocombo box configuration. Is there a way to do this?
I am referring to the form I posted earlier in another thread in the Sencha forums, but no one has answered. The url is:
http://www.sencha.com/forum/showthre...ng-Sencha-form
I tried this:
var myNewStore =[
"", "Yes", "Revoke"];
Ext.define('YesNoCombo',{
extend:'Ext.form.ComboBox',
store:myNewStore,
value:'',
emptyText:'Select...',
labelalign:'left',
labelWidth:550,
inputWidth:80,
allowBlank:true,
listeners:{
select:function(comp,record,index){
if(comp.getVelue() == "" || comp.getVale() ===" ")
comp.setValue(null);
}
}
});
but this broke the format of the form.
Is there a way to create a local combo with custom variables like this:
var UserForm_BlahBlahBlah=Ext.create('YesNoCombo', {
name:"UserForm_BlahBlahBlah",
fieldLabel:"BlahBlahBlah",
values:" Yes" "Revoke",
});
I tried this but it will not work. But you get the idea- It is just creating a local extension within a specific panel with new values.
Is this possible? Or is there a better way that sencha implements customizing the combo box with out affecting the parent class?

You can easily extend Ext.form.ComboBox class and create your own combo box class. Then you can use your combobox in forms.
In the exmaple I create custom combobox by using its xtype which I defined by alias: 'widget.yesNoCombo'. You can also create instance of custom combobox by var combo = Ext.create('YesNoCombo');
Ext.define('YesNoCombo',{
alias: 'widget.yesNoCombo',
extend:'Ext.form.ComboBox',
store: ["No", "Yes", "Revoke"],
emptyText:'Select...',
allowBlank:true
});
Ext.create('Ext.form.Panel', {
renderTo: Ext.getBody(),
items:[
{
xtype: 'yesNoCombo',
fieldLabel:'Yes No Label',
name: 'combo',
},
{
xtype: 'textfield',
fieldLabel: 'Another field',
name: 'anotherField',
},
]
});

I want to change the "labelAlign" of all field component in the page to "right".
Now, I have to add the default config below to all panel in the page to implement that.
defaults:
{
labelAlign: 'right',
labelSeparator: "："
}
Is there any once code way to change the default values of the properties I specified of all the extjs components in the page?
Thank you for any help in advance!
Setting defaults in the highest level container of the view should apply that config to any children that do not already have a value set.
If one or more of the children (field components) already have a labelAlign config then you might try doing:
allYourFields = Ext.ComponentQuery.query('textfield');
Ext.forEach(allYourFields, function(field){
field.labelAlign = 'right';
});
Are there any color picker for extjs (such as photo shop color picker) that developed only on extjs (not in jQuery).
I’m using (Ext.ux.ColorPicker) ux.colorpicker but, it can’t fill my requirement.
Thanks,
Thanuja.
ExtJS has a simple colorpicker.
xtype: 'colorpicker'
From the help:
Ext.create('Ext.picker.Color', {
value: '993300', // initial selected color
renderTo: Ext.getBody(),
listeners: {
select: function(picker, selColor) {
alert(selColor);
}
}
});
You can also look at this one which is more Photoshop-esque and works with Ext JS 4x+, but does require canvas support.
I realize this is an old question. but nevertheless for people looking to have these two libraries play nice... here is what I did. The problem lay in that jscolor expects all the inputs with class "color" to be available on window.load, which is called via jscolor.install(). Of course, ExtJs elements are not available at that time. Try this:
Ext.create("Ext.form.field.Text",{
renderTo: Ext.getBody(),
fieldCls:"color",
name:"TestPost",
listeners: {
afterrender: {
delay:200,
fn:function(item){
jscolor.init();
}
}
}
});
Running jscolor.init() will start it all up. If you like, you can comment out the jscolor.install() call at the bottom of the jscolor.js file, so long as you call jscolor.init() as a listener that runs after the rendering of the textfield you want to be your color picker.
I have an Ext TabPanel, and I am trying to set the hidden property for one of the Tabs, programmatically. I am able to select the object and call methods such as disable() and enable() but so far have been unable to find a means by which I can manipulate the Tab's 'hidden' property.
The Tab is defined as
{
id: "view-task",
hidden: false,
title: "View"
}
and the code attempting to manipulate it
twin = ( Ext.getCmp('view-task'));
twin.disable();
The above call to disable works, so the component is being correctly selected but I do not know how to manipulate the hidden property.
Any assistance will be much appreciated.

Try this:
var tabs = Ext.createWidget('tabpanel', {
items: [{
itemId: 'home',
contentEl:'script',
title: 'Short Text',
closable: true
}]
});
tabs.child('#home').tab.hide();
You can find this code in examples on the API page
You haven't explained which version of ExtJS you're using. But in version 3.x you can do the following (I don't know, but it might also work in ExtJS 4.x):
var tabPanel = Ext.getCmp('myTabPanel');
var tabToHide = Ext.getCmp('myTab');
tabPanel.hideTabStripItem(tabToHide);
To show the tab again:
tabPanel.unhideTabStripItem(tabToHide);
Hope this helps you :)
