Many classes have shortcut names used when creating (instantiating) a class with a
configuration object. The shortcut name is referred to as an alias (or xtype if the
class extends Ext.Component). The alias/xtype is listed next to the class name of
applicable classes for quick reference.
Framework classes or their members may be specified as private or protected. Else,
the class / member is public. Public, protected, and private are access
descriptors used to convey how and when the class or class member should be used.
Public classes and class members are available for use by any other class or application code and may be relied upon as a stable and persistent within major product versions. Public classes and members may safely be extended via a subclass.
Protected class members are stable public members intended to be used by the
owning class or its subclasses. Protected members may safely be extended via a subclass.
Private classes and class members are used internally by the framework and are not intended to be used by application developers. Private classes and members may change or be omitted from the framework at any time without notice and should not be relied upon in application logic.
static label next to the
method name. *See Static below.Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).
Let's look at each part of the member row:
lookupComponent in this example)( item ) in this example)Ext.Component in this case). This may be omitted for methods that do not
return anything other than undefined or may display as multiple possible values
separated by a forward slash / signifying that what is returned may depend on the
results of the method call (i.e. a method may return a Component if a get method calls is
successful or false if unsuccessful which would be displayed as
Ext.Component/Boolean).PROTECTED in
this example - see the Flags section below)Ext.container.Container in this example). The source
class will be displayed as a blue link if the member originates from the current class
and gray if it is inherited from an ancestor or mixed-in class.view source in the example)item : Object in the example).undefined a "Returns" section
will note the type of class or object returned and a description (Ext.Component in the
example)Available since 3.4.0 - not pictured in
the example) just after the member descriptionDefaults to: false)The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.
classInstance.method1().method2().etc();false is returned from
an event handler- Indicates a framework class
- A singleton framework class. *See the singleton flag for more information
- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)
- Indicates that the class, member, or guide is new in the currently viewed version

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.
Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.
Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.
Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.
If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.
Both API docs and guides can be searched for using the search field at the top of the page.
On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.
The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.
Clicking on an empty search field will show your last 10 searches for quick navigation.
Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:
Ext.button.Button class has an alternate class name of Ext.Button). Alternate class
names are commonly maintained for backward compatibility.Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.
Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.
Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:
The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.
For an overview of calendar views see Ext.calendar.view.Base
The Weeks view shows the events for one or more weeks as full days similar to a conventional calendar. For a week view including an hourly timeline see Ext.calendar.view.Week.
The weeks view shows the week containing the current date (or the date set on the cfg-value config) plus any additional weeks totaling the cfg-visibleWeeks. The number of days shown per week is set using cfg-visibleDays. Each week begins on the day set on the cfg-firstDayOfWeek.
By default the first day is Sunday. If you want to create a "work week" type view
where the weekend days are omitted you can modify the visibleDays and
firstDayOfWeek to show only Monday - Friday.
Ext.create({
xtype: 'calendar-weeksview',
renderTo: Ext.getBody(),
height: 400,
width: 400,
firstDayOfWeek: 1, // starts the view on Monday
visibleDays: 5, // and displays it and the 4 days after
store: {
autoLoad: true,
proxy: {
type: 'ajax',
url: 'calendars.php'
},
eventStoreDefaults: {
proxy: {
type: 'ajax',
url: 'events.php'
}
}
}
});
Events show on the view with their start and end days correlating to the day labels. The events will display on the timeline according to your local timezone offset from GMT. The timezone offset can be applied explicitly using the cfg-timezoneOffset config option.
Dragging / swiping across multiple days will show the event add form with multiple days pre-populated in the form's start / end dates. A single all day type event can be added by tapping / clicking on a single day.
The movePrevious and moveNext methods modify the displayed date range by moving the range forward or backward the number of cfg-visibleWeeks.
i.e. view.moveNext(); called on a 7-day view with 2 visible weeks will advance the
view 2 weeks. Note that a view configured with 5 visibleDays would not advance
5 days, but rather will show the next full week with only 5 visible days.
If your view requires a header showing the days of the week consider using Ext.calendar.panel.Weeks instead. For a month view refer to Ext.calendar.view.Month.
The configuration for the Ext.calendar.form.Add to be used
when an event is to be created. Use null to disable creation.
Defaults to:
{
xtype: 'calendar-form-add'
}
true to show the cfg-addForm when a selection is made on the body.
Use cfg-addOnSelect to control view selection itself.
Defaults to:
true
true to allow days to be selected via the UI.
Defaults to:
true
Sets the value of allowSelection
allowSelection : Boolean
true to display this view in compact mode, typically used
for smaller form factors. Setting to true applies any configured
cfg-compactOptions.
Defaults to:
false
A series of config options for this class to set when this class is in cfg-compact mode.
Defaults to:
null
Sets the value of compactOptions
compactOptions : Object
true to allow this view to set the date range on event stores
in reaction to the value changing. The need to disable this surfaces
when using multiple views together and allowing one view (the one with
the largest range) to be the in control of loading the stores.
Defaults to:
true
Sets the value of controlStoreRange
controlStoreRange : Boolean
The format for displaying the day in the cell. See Ext.Date for options.
Defaults to:
'j'
The configuration for the Ext.calendar.form.Edit to be used
when an event is to be modified. Use null to disable editing.
Defaults to:
{
xtype: 'calendar-form-edit'
}
The default configuration for Ext.calendar.Event widgets
Defaults to:
{
xtype: 'calendar-event'
}
The day on which the calendar week begins. 0 (Sunday) through 6 (Saturday).
Defaults to Ext.Date#firstDayOfWeek
Defaults to:
undefined
Sets the value of firstDayOfWeek
firstDayOfWeek : Number
A Ext.calendar.header.Base object to link to this view
Defaults to:
null
Text to show when events overflow on a particular day to allow the user to view the rest. This string is evaluated as a formatted string where the argument is the number of overflowing events. Depends on cfg-showOverflow.
Defaults to:
'+{0} more'
Show an overflow label that will display an overlay when there are too many events to render in the view. Valid configurations are:
topbottomPass null or '' to not show overflow.
The overflow text may be formatted using cfg-overflowText.
Defaults to:
'bottom'
A Ext.calendar.store.Calendars instance or configuration
Defaults to:
null
The timezone offset to display this calendar in. The value should be specified in the same way as the native Date offset. That is, the number of minutes between UTC and local time. For example the offset for UTC+10 would be -600 (10 hours * 60 minutes ahead).
Defaults to the current browser offset.
Defaults to:
undefined
Sets the value of timezoneOffset
timezoneOffset : Number
The start of the date range to show. The visible range of the view will begin at the firstDayOfWeek immediately preceding this value or the value if it is the firstDayOfWeek. For example, using the following configuration:
{
firstDayOfWeek: 0, // Sunday
value: new Date(2010, 2, 3) // Wed, 3 March 2010
}
The visible range would begin on Sun 28th Feb.
Defaults to:
new Date()
The number of days to show in a week, starting from the firstDayOfWeek.
For example, to show the view with days Mon - Fri, use:
{
visibleDays: 5,
firstDayOfWeek: 1 // Monday
}
Defaults to:
7
The days of the week that are the weekend. 0 (Sunday) through 6 (Saturday).
Defaults to Ext.Date#weekendDays.
Defaults to:
undefined
The value true causes config values to be stored on instances using a
property name prefixed with an underscore ("_") character. A value of false
stores config values as properties using their exact name (no prefix).
Defaults to:
true
Available since: 5.0.0
The value true instructs the initConfig method to only honor values for
properties declared in the config block of a class. When false, properties
that are not declared in a config block will be placed on the instance.
Defaults to:
true
Available since: 5.0.0
Setting this property to false will prevent nulling object references
on a Class instance after destruction. Setting this to "async" will delay
the clearing for approx 50ms.
Defaults to:
true
Available since: 6.2.0
Setting this property to true will result in setting the object's
prototype to null after the destruction sequence is fully completed.
After that, most attempts at calling methods on the object instance
will result in "method not defined" exception. This can be very helpful
with tracking down otherwise hard to find bugs like runaway Ajax requests,
timed functions not cleared on destruction, etc.
Note that this option can only work in browsers that support Object.setPrototypeOf
method, and is only available in debugging mode.
Defaults to:
false
Available since: 6.2.0
This property is set to true after the destroy method is called.
Defaults to:
false
Get the period to move when using moveNext and movePrevious.
Defaults to:
Ext.privateFn
The period to move
This property is set to true during the call to initConfig.
Defaults to:
false
Available since: 5.0.0
This property is set to true if this instance is the first of its class.
Defaults to:
false
Available since: 5.0.0
This value is true and is used to identify plain objects from instances of
a defined class.
Defaults to:
true
Get the reference to the current class from which this object was instantiated. Unlike Ext.Base#statics,
this.self is scope-dependent and it's meant to be used for dynamic inheritance. See Ext.Base#statics
for a detailed comparison
Ext.define('My.Cat', {
statics: {
speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
},
constructor: function() {
alert(this.self.speciesName); // dependent on 'this'
},
clone: function() {
return new this.self();
}
});
Ext.define('My.SnowLeopard', {
extend: 'My.Cat',
statics: {
speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
}
});
var cat = new My.Cat(); // alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
Defaults to:
Base
A date where the month starts on a Sunday. Used to generate day names.
Defaults to:
new Date(2000, 9, 1)
true to track the date ranges in the view to add past/future date classes.
Defaults to:
false
This method applies a versioned, deprecation declaration to this class. This
is typically called by the deprecated config.
deprecations : Object
Call the original method that was previously overridden with Ext.Base#override
Ext.define('My.Cat', {
constructor: function() {
alert("I'm a cat!");
}
});
My.Cat.override({
constructor: function() {
alert("I'm going to be a cat!");
this.callOverridden();
alert("Meeeeoooowwww");
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
Deprecated since version 4.1.0
Use method-callParent instead.
Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext#define).
Ext.define('My.Base', {
constructor: function (x) {
this.x = x;
},
statics: {
method: function (x) {
return x;
}
}
});
Ext.define('My.Derived', {
extend: 'My.Base',
constructor: function () {
this.callParent([21]);
}
});
var obj = new My.Derived();
alert(obj.x); // alerts 21
This can be used with an override as follows:
Ext.define('My.DerivedOverride', {
override: 'My.Derived',
constructor: function (x) {
this.callParent([x*2]); // calls original My.Derived constructor
}
});
var obj = new My.Derived();
alert(obj.x); // now alerts 42
This also works with static and private methods.
Ext.define('My.Derived2', {
extend: 'My.Base',
// privates: {
statics: {
method: function (x) {
return this.callParent([x*2]); // calls My.Base.method
}
}
});
alert(My.Base.method(10)); // alerts 10
alert(My.Derived2.method(10)); // alerts 20
Lastly, it also works with overridden static methods.
Ext.define('My.Derived2Override', {
override: 'My.Derived2',
// privates: {
statics: {
method: function (x) {
return this.callParent([x*2]); // calls My.Derived2.method
}
}
});
alert(My.Derived2.method(10); // now alerts 40
To override a method and replace it and also call the superclass method, use method-callSuper. This is often done to patch a method to fix a bug.
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.
Consider:
Ext.define('Ext.some.Class', {
method: function () {
console.log('Good');
}
});
Ext.define('Ext.some.DerivedClass', {
extend: 'Ext.some.Class',
method: function () {
console.log('Bad');
// ... logic but with a bug ...
this.callParent();
}
});
To patch the bug in Ext.some.DerivedClass.method, the typical solution is to create an
override:
Ext.define('App.patches.DerivedClass', {
override: 'Ext.some.DerivedClass',
method: function () {
console.log('Fixed');
// ... logic but with bug fixed ...
this.callSuper();
}
});
The patch method cannot use method-callParent to call the superclass
method since that would call the overridden method containing the bug. In
other words, the above patch would only produce "Fixed" then "Good" in the
console log, whereas, using callParent would produce "Fixed" then "Bad"
then "Good".
args : Array/Arguments
The arguments, either an array or the arguments object
from the current method, for example: this.callSuper(arguments)
Returns the result of calling the superclass method

Get the reference to the class from which this object was instantiated. Note that unlike Ext.Base#self,
this.statics() is scope-independent and it always returns the class from which it was called, regardless of what
this points to during run-time
Ext.define('My.Cat', {
statics: {
totalCreated: 0,
speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
},
constructor: function() {
var statics = this.statics();

// equivalent to: My.Cat.speciesName
alert(this.self.speciesName); // dependent on 'this'
statics.totalCreated++;
},
clone: function() {

The offset date
Destroys a given set of linked objects. This is only needed if
the linked object is being destroyed before this instance.
names : String[]
The names of the linked objects to destroy.
this
Get a UTC date as a local date, taking into account the timezoneOffset.
For example, if the current date is:
Thu May 05 2016 10:00:00 GMT+1000 and the timezoneOffset is -60, then the value will
be Thu May 05 2016 01:00:00 GMT+1000.
d : Date

Adds new config properties to this class. This is called for classes when they are declared, then for any mixins that class may define and finally for any overrides defined that target the class.
config : Object
mixinClass : Ext.Class (optional)
The mixin class if the configs are from a mixin.
Add methods / properties to the prototype of this class.
Ext.define('My.awesome.Cat', {
constructor: function() {
...
}
});
My.awesome.Cat.addMembers({
meow: function() {
alert('Meowww...');
}
});
var kitty = new My.awesome.Cat();
kitty.meow();
members : Object
The members to add to this class.
isStatic : Boolean (optional)
Pass true if the members are static.
Defaults to: false
privacy : Boolean (optional)
Pass true if the members are private. This
only has meaning in debug mode and only for methods.
Defaults to: false
Add / override static properties of this class.
Ext.define('My.cool.Class', {
...
});
My.cool.Class.addStatics({
someProperty: 'someValue', // My.cool.Class.someProperty = 'someValue'
method1: function() { ... }, // My.cool.Class.method1 = function() { ... };
method2: function() { ... } // My.cool.Class.method2 = function() { ... };
});
members : Object
this
Borrow another class' members to the prototype of this class.
Ext.define('Bank', {
money: '$$$',
printMoney: function() {
alert('$$$$$$$');
}
});
Ext.define('Thief', {
...
});
Thief.borrow(Bank, ['money', 'printMoney']);
var steve = new Thief();
alert(steve.money); // alerts '$$$'
steve.printMoney(); // alerts '$$$$$$$'
fromClass : Ext.Base
The class to borrow members from
members : Array/String
The names of the members to borrow
this
Create a new instance of this Class.
Ext.define('My.cool.Class', {
...
});
My.cool.Class.create({
someConfig: true
});
All parameters are passed to the constructor of the class.
the created instance.
Create aliases for existing prototype methods. Example:
Ext.define('My.cool.Class', {
method1: function() { ... },
method2: function() { ... }
});
var test = new My.cool.Class();
My.cool.Class.createAlias({
method3: 'method1',
method4: 'method2'
});
test.method3(); // test.method1()
My.cool.Class.createAlias('method5', 'method3');
test.method5(); // test.method3() -> test.method1()
alias : String/Object
The new method name, or an object to set multiple aliases. See flexSetter
origin : String/Object
The original method name
Returns the Ext.Configurator for this class.
Get the current class' name in string format.
Ext.define('My.cool.Class', {
constructor: function() {
alert(this.self.getName()); // alerts 'My.cool.Class'
}
});
My.cool.Class.getName(); // 'My.cool.Class'
className
Used internally by the mixins pre-processor
name : Object
mixinClass : Object
Override members of this class. Overridden methods can be invoked via Ext.Base#callParent.
Ext.define('My.Cat', {
constructor: function() {
alert("I'm a cat!");
}
});
My.Cat.override({
constructor: function() {
alert("I'm going to be a cat!");
this.callParent(arguments);
alert("Meeeeoooowwww");
}
});
var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
// alerts "I'm a cat!"
// alerts "Meeeeoooowwww"
Direct use of this method should be rare. Use Ext.define instead:
Ext.define('My.CatOverride', {
override: 'My.Cat',
constructor: function() {
alert("I'm going to be a cat!");
this.callParent(arguments);
alert("Meeeeoooowwww");
}
});
The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).
