Terms, Icons, and Labels

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.

Access Levels

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.

Member Types

Config - The configuration options for a class.
Property - Set once a class is instantiated. *See Read Only below.
Method - Actions that can be performed by a class. Methods should be read as instance methods and can only be called from a instance of a given class. Static methods that can be called directly from the class itself will have a static label next to the method name. *See Static below.
Event - Events are specific to the framework event system allowing for classes to programmatically raise an event to be handled by one or more event handler methods. DOM events, while handled by the framework event system, are not specifically described within the API documentation. *For DOM events refer to the event reference page from MDN.
Theme Variable - Variables used by the visual theme engine employed by the framework.
Theme Mixin - Functions used by the visual theme engine employed by the framework and may use values set in various Theme Variables.

Member Syntax

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).

lookupComponent ( item ) : Ext.Component

Called when a raw config object is added to this container either during initialization of the items config, or when new items are added), or {@link #insert inserted.

This method converts the passed object into an instanced child component.

This may be overridden in subclasses when special processing needs to be applied to child creation.

item : Object

The config object being added.

Ext.Component

The component to be added.

Let's look at each part of the member row:

Expand/Collapse - On the left-hand size of the member row is a control used to expand and collapse each member row to show / hide member details.
Member Name - The name of the class member (lookupComponent in this example)
Method Param - Any required or optional params used by a method (or passed to an event handler method) will be listed next to the method name within parenthesis (( item ) in this example)
Return type - The class instance or javascript object returned by the method or property (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).
Flags - Any flags applicable to the member will be displayed next (PROTECTED in this example - see the Flags section below)
Member Origin - On the right-hand side of the member row is the class where the member was initially described (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.
Member Source - On the right-hand side below the member origin class is a link to view the member's source (view source in the example)
Params List - Each param for a class method will be listed using the same name found above in parenthesis, the type of class or object expected, and a description of the param (item : Object in the example).
Returns - If a class returns a value other than undefined a 'Returns' section will note the type of class or object returned and a description (Ext.Component in the example)
Since (not shown in the example) - Some members will show which version of the product the member was first introduced (i.e. Available since 3.4.0 - not pictured in the example) just after the member description
Default (not shown in the example) - Configs often show the default config value to be applied to a class instance if not overridden (i.e. Defaults to: false)

Member Flags

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.

Required - Required config when instantiating a class
Bindable - The config has a setter which allows this config to be set via ViewModel binding
Read Only - The property may be read, but cannot be used to configure / re-configure a class instance at runtime
Singleton - Singleton classes are instantiated immediately once defined and may not be instantiated manually
Static - A static method or property is a method or property belonging to the class itself, not an instance of the class
Chainable - Refers to methods that return the class instance back when called.
This enables chained method calls like: classInstance.method1
