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.

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.
Ext.XTemplate
Ext.overrides.dom.Element
A mixin which allows a component to be configured and decorated with a label and/or error message as is common for form fields. This is used by e.g. Ext.form.field.Base and Ext.form.FieldContainer to let them be managed by the Field layout.
NOTE: This mixin is mainly for internal library use and most users should not need to use it directly. It is more likely you will want to use one of the component classes that import this mixin, such as Ext.form.field.Base or Ext.form.FieldContainer.
Use of this mixin does not make a component a field in the logical sense, meaning it does not provide any logic or state related to values or validation; that is handled by the related Ext.form.field.Field mixin. These two mixins may be used separately (for example Ext.form.FieldContainer is Labelable but not a Field), or in combination (for example Ext.form.field.Base implements both and has logic for connecting the two.)
Component classes which use this mixin should use the Field layout or a derivation thereof to properly size and position the label and message according to the component config. They must also call the initLabelable method during component initialization to ensure the mixin gets set up correctly.
If specified, then the component will be displayed with this value as its active error when first rendered. Use setActiveError or unsetActiveError to change it after component creation.
Gets the active error message for this component, if any. This does not trigger validation on its own, it merely returns any message that the component may already hold.
The active error message on the component; if there is no error, an empty string is returned.
Sets the active error message to the given string. This replaces the entire error message contents with the given string. Also see setActiveErrors which accepts an Array of messages and formats them according to the activeErrorsTpl. Note that this only updates the error message element's text and attributes, you'll have to call doComponentLayout to actually update the field's layout to match. If the field extends Ext.form.field.Base you should call markInvalid instead.
msg : String
The error message
The template used to format the Array of error messages passed to setActiveErrors into a single HTML string. if the msgTarget is title, it defaults to a list separated by new lines. Otherwise, it renders each message as an item in an unordered list.
Defaults to:
undefined
An optional string or XTemplate configuration to insert in the field markup
at the end of the input containing element. If an XTemplate is used, the component's render data
serves as the context.
An optional string or XTemplate configuration to insert in the field markup
after the label text. If an XTemplate is used, the component's render data
serves as the context.
An optional string or XTemplate configuration to insert in the field markup
after the label element. If an XTemplate is used, the component's render data
serves as the context.
An optional string or XTemplate configuration to insert in the field markup
after the subTpl markup. If an XTemplate is used, the
component's render data serves as the context.
Whether to adjust the component's body width to make room for 'side' error messages.
Defaults to:
true
The CSS class to be applied to the body content element.
Defaults to:
Ext.baseCSSPrefix + 'form-item-body'
An optional string or XTemplate configuration to insert in the field markup
at the beginning of the input containing element. If an XTemplate is used, the component's render data
serves as the context.
An optional string or XTemplate configuration to insert in the field markup
before the label text. If an XTemplate is used, the component's render data
serves as the context.
An optional string or XTemplate configuration to insert in the field markup
before the label element. If an XTemplate is used, the component's render data
serves as the context.
An optional string or XTemplate configuration to insert in the field markup
before the subTpl markup. If an XTemplate is used, the
component's render data serves as the context.
The CSS class to be applied to the error message element.
Defaults to:
Ext.baseCSSPrefix + 'form-error-msg'
An extra CSS class to be applied to the body content element in addition to baseBodyCls.
Defaults to:
''
The label for the field. It gets appended with the labelSeparator, and its position and sizing is determined by the labelAlign and labelWidth configs.
Defaults to:
undefined
Returns the label for the field. Defaults to simply returning the fieldLabel config. Can be overridden to provide a custom generated label.
The configured field label, or empty string if not defined
This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.
Set the label of this field.
label : String
The new label. The labelSeparator will be automatically appended to the label string.
A CSS class to be applied to the outermost element to denote that it is participating in the form field layout.
Defaults to:
Ext.baseCSSPrefix + 'form-item'
When set to true, the label element (fieldLabel and labelSeparator) will be automatically hidden if the fieldLabel is empty. Setting this to false will cause the empty label element to be rendered and space to be reserved for it; this is useful if you want a field without a label to line up with other labeled fields in the same form.
If you wish to unconditionall hide the label even if a non-empty fieldLabel is configured, then set the hideLabel config to true.
Defaults to:
true
Set to true to completely hide the label element (fieldLabel and labelSeparator). Also see hideEmptyLabel, which controls whether space will be reserved for an empty fieldLabel.
Defaults to:
false
The CSS class to use when marking the component invalid.
Defaults to:
Ext.baseCSSPrefix + 'form-invalid'
The rendering template for the field decorations. Component classes using this mixin should include logic to use this as their renderTpl, and implement the getSubTplMarkup method to generate the field body content.
Defaults to:
[
'{beforeLabelTpl}',
'<label id="{id}-labelEl" data-ref="labelEl" class="{labelCls} {labelCls}-{ui} {labelClsExtra} ',
'{unselectableCls}" style="{labelStyle}"<tpl if="inputId">',
' for="{inputId}"</tpl> {labelAttrTpl}>',
'<span class="{labelInnerCls} {labelInnerCls}-{ui}" style="{labelInnerStyle}">',
'{beforeLabelTextTpl}',
'<tpl if="fieldLabel">{fieldLabel}',
'<tpl if="labelSeparator">{labelSeparator}</tpl>',
'</tpl>',
'{afterLabelTextTpl}',
'</span>',
'</label>',
'{afterLabelTpl}',
'<div id="{id}-bodyEl" data-ref="bodyEl" role="presentation"',
' class="{baseBodyCls} {baseBodyCls}-{ui}<tpl if="fieldBodyCls">',

'<tpl if="bodyStyle"> style="{bodyStyle}"</tpl>>',
'{beforeBodyEl}',
'{beforeSubTpl}',
'{[values.$comp.getSubTplMarkup(values)]}',
'{afterSubTpl}',
'{afterBodyEl}',
// Unlike errorEl below ariaErrorEl is always rendered but is clipped out of existence
'<div id="{id}-ariaErrorEl" data-ref="ariaErrorEl" role="alert" aria-live="polite"',
' class="' + Ext.baseCSSPrefix + 'hidden-clip">',
'</div>',
'</div>',
'<tpl if="renderError">',
'<div id="{id}-errorWrapEl" data-ref="errorWrapEl" class="{errorWrapCls} {errorWrapCls}-{ui}',
' {errorWrapExtraCls}" style="{errorWrapStyle}">',

'data-anchorTarget="{tipAnchorTarget}">',
'</div>',
'</div>',
'</tpl>',
{
disableFormats: true
}
]
Controls the position and alignment of the fieldLabel. Valid values are:
Defaults to:
'left'
An optional string or XTemplate configuration to insert in the field markup
inside the label element (as attributes). If an XTemplate is used, the component's
render data serves as the context.
The CSS class to be applied to the label element. This (single) CSS class is used to formulate the renderSelector and drives the field layout where it is concatenated with a hyphen ('-') and labelAlign. To add additional classes, use labelClsExtra.
Defaults to:
Ext.baseCSSPrefix + 'form-item-label'
An optional string of one or more additional CSS classes to add to the label element. Defaults to empty.
The amount of space in pixels between the fieldLabel and the field body.
This defaults to 5 for compatibility with Ext JS 4, however, as of Ext JS 5
the space between the label and the body can optionally be determined by the theme
using the $form-label-horizontal-spacing (for side-aligned labels) and
$form-label-vertical-spacing (for top-aligned labels) SASS variables.
In order for the stylesheet values as to take effect, you must use a labelPad value
of null.
Defaults to:
5
Character(s) to be inserted at the end of the label text.
Set to empty string to hide the separator completely.
Defaults to:
':'
The width of the fieldLabel in pixels. Only applicable if labelAlign is set to "left" or "right".
Defaults to:
100
The location where the error message text should display. Must be one of the following values:
qtip Display a quick tip containing the message when the user hovers over the field.
This is the default.
Ext.tip.QuickTipManager#init must have been called for this setting to work.
title Display the message in a default browser title attribute popup.
under Add a block div beneath the field containing the error message.side Add an error icon to the right of the field, displaying the message in a popup on hover.none Don't display any error message. This might be useful if you are implementing custom error display.[element id] Add the error message directly to the innerHTML of the specified element.Defaults to:
'qtip'
true to disable displaying any error message set on this object.
Defaults to:
false
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
The div Element wrapping the component's contents. Only available after the component has been rendered.
This property is set to true after the destroy method is called.
Defaults to:
false
The div Element that will contain the component's error message(s). Note that depending on the configured msgTarget, this element may be hidden in favor of some other form of presentation, but will always be present in the DOM for use by assistive technologies.
This property is set to true during the call to initConfig.
Defaults to:
false
Available since: 5.0.0
Flag denoting that this object is labelable as a field. Always true.
Defaults to:
true
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
The label Element for this component. Only available after the component has been rendered.
Map for msg target lookup, if target is not in this map it is assumed to be an element id
Defaults to:
{
qtip: 1,
title: 1,
under: 1,
side: 1,
none: 1
}
Tells the layout system that the height can be measured immediately because the width does not need setting.
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
This method applies a versioned, deprecation declaration to this class. This
is typically called by the deprecated config.
deprecations : Object
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 methods.
Ext.define('My.Derived2', {
extend: 'My.Base',
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',
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 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 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
This method is called to cleanup an object and its resources. After calling this method, the object should not be used any further.
Gets an Array of any active error messages currently applied to the field. This does not trigger validation on its own, it merely returns any messages that the component may already hold.
The active error messages on the component; if there are no errors, an empty Array is returned.
Returns a specified config property value. If the name parameter is not passed, all current configuration options will be returned as key value pairs.
name : String (optional)
The name of the config property to get.
peek : Boolean (optional)
true to peek at the raw value without calling the getter.
Defaults to: false
The config property value.
Returns the initial configuration passed to constructor when instantiating this class.
name : String (optional)
Name of the config option to return.
The full config object or a single config value
when name parameter specified.
Get the input id, if any, for this component. This is used as the "for" attribute on the label element. Implementing subclasses may also use this as e.g. the id for their own input element.
The input id
Generates the arguments for the field decorations rendering template.
data : Object
optional object to use as the base data object. If provided, this method will add properties to the base object instead of creating a new one.
The template arguments
Gets the markup to be inserted into the outer template's bodyEl. Defaults to empty string, should be implemented by classes including this mixin as needed.
The markup to be inserted
Tells whether the field currently has an active error message. This does not trigger validation on its own, it merely looks for any message that the component may already hold.
Checks if the field has a visible label
True if the field has a visible label
Initialize configuration for this class. a typical example:
Ext.define('My.awesome.Class', {
// The default config
config: {
name: 'Awesome',
isAwesome: true
},
constructor: function(config) {
this.initConfig(config);
}
});
var awesome = new My.awesome.Class({
name: 'Super Awesome'
});
alert(awesome.getName()); // 'Super Awesome'
config : Object
this
Performs initialization of this mixin. Component classes using this mixin should call this method during their own initialization.
Adds a "destroyable" object to an internal list of objects that will be destroyed
when this instance is destroyed (via destroy).
name : String
value : Object
The value passed.
Updates the rendered DOM to match the current activeError. This only updates the content and attributes, you'll have to call doComponentLayout to actually update the display.
Set the active error message to an Array of error messages. The messages are formatted into a single message string using the activeErrorsTpl. Also see setActiveError which allows setting the entire error contents with a single string. Note that this only updates the error message element's text and attributes, you'll have to call doComponentLayout to actually update the field's layout to match. If the field extends Ext.form.field.Base you should call markInvalid instead.
errors : String[]
The error messages
Sets a single/multiple configuration options.
name : String/Object
The name of the property to set, or a set of key value pairs to set.
value : Object (optional)
The value to set for the name parameter.
this
Applies a set of default configuration values to this Labelable instance. For each of the properties in the given object, check if this component hasOwnProperty that config; if not then it's inheriting a default value from its prototype and we should apply the default value.
defaults : Object
The defaults to apply to the object.
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();
alert(statics.speciesName); // always equals to 'Cat' no matter what 'this' refers to
// equivalent to: My.Cat.speciesName
alert(this.self.speciesName); // dependent on 'this'
statics.totalCreated++;
},
clone: function() {
var cloned = new this.self(); // dependent on 'this'
cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName
return cloned;
}
});
Ext.define('My.SnowLeopard', {
extend: 'My.Cat',
statics: {
speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
},
constructor: function() {
this.callParent();
}
});
var cat = new My.Cat(); // alerts 'Cat', then alerts 'Cat'
var snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'
var clone = snowLeopard.clone();
alert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'
alert(clone.groupName); // alerts 'Cat'
alert(My.Cat.totalCreated); // alerts 3
Returns the trimmed label by slicing off the label separator character. Can be overridden.
The trimmed field label, or empty string if not defined
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
Clears the active error message(s). Note that this only clears the error message element's text and attributes, you'll have to call doComponentLayout to actually update the field's layout to match. If the field extends Ext.form.field.Base you should call clearInvalid instead.
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

}
});
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).
