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.

Member Types

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.


The component to be added.

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

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.

Class Icons

- 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

Member Icons

- Indicates a class member of type config

- Indicates a class member of type property

- Indicates a class member of type method

- Indicates a class member of type event

- Indicates a class member of type theme variable

- Indicates a class member of type theme mixin

- Indicates that the class, member, or guide is new in the currently viewed version

Class Member Quick-Nav Menu

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.

Getter and Setter Methods

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.

History Bar

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.

Search and Filters

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.

API Doc Class Metadata

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:

Expanding and Collapsing Examples and Class Members

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.

Desktop -vs- Mobile View

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:

Viewing the Class Source

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.

Architect 4


What's New in Architect 4

We are pleased to announce the release of Architect 4. Architect 4.0 provides support for Ext JS 6 Modern toolkit, whilc will allow you to build advanced mobile applications with a single code base.

You can download Architect 4.0 here. Please be sure to give us your feedback in the Architect 4.0 forum so that we can make the GA everything you want it to be.

What's New

Ext JS 6 Modern Toolkit Support

Architect 4.0 supports Ext JS 6 Modern toolkit along with Classic toolkit, so you can easily develop new Ext JS modern applications within Architect for use on mobile devices as well as for modern browsers on desktop. You should consider migrating to Ext JS 6 Modern toolkit if you’re currently using Sencha Touch. Please refer to the upgrade documentation guide for details.

Architect 4.0 offers the ability to use the Triton theme for your Ext JS 6 modern application. Triton is a flat and minimalistic theme with support for “font icons”. Architect comes with a GUI-based themeroller to help you modify existing themes or create your own.

Hybrid Mobile Apps with Ext JS Modern Toolkit

Architect 4.0 helps you create hybrid mobile applications for iOS and Android. Architect 4.0 provides a UI to add a Cordova/PhoneGap build profile in app.json, add Cordova within an Ext JS modern app, build a native app, and run in an emulator. You should have Node.js, Cordova/PhoneGap along with XCode for creating iOS apps, and Android Studio/SDK for creating Android apps.

Import from Sencha Themer

Architect 4.0 allows you to import themes created using our new tool, Sencha Themer. You can create custom themes using Sencha Themer and simply open that theme package within Architect by adding it as a Theme resource. Architect will copy the theme package into the project folder and apply the theme.

Live Update using Sencha Cmd and Fashion

Architect 4.0 allows you to modify the SASS files in your Ext JS 6 modern application and see the changes live. Architect leverages the Ext JS theme compiler, Fashion, to compile SASS and inject updated CSS into your running web apps. This means you don't have to reload to see theme changes, instead you see the updates in near real-time, directly in your browser.

Enhanced Performance

Architect 4.0 uses the latest GitHub Electron for packaging, which brings performance improvements and stability to the Architect application.

Supported Versions

Architect 4.0 enables users to create Ext JS apps using Ext JS 6 Modern toolkit and Ext JS 4.x, 5.x and 6.x Classic toolkit. Architect 4.0 does not support Sencha Touch. Touch users can continue to use Architect 3.5.
