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.

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
- Indicates a class member of type config
- Indicates a class member of type property
- Indicates a class member of type

- 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 and inheritance. This is done using the checkboxes at the top of
the page. Note that filtering out private
members also filters the API class
navigation tree.
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.
Key/Value store for files. Files stored using this API are encrypted automatically using Sencha Web Application Manager's security infrastructure.
var files = Ext.space.SecureFiles.get('secrets');
files.get('myKey').then(function(contents){
// do something with the content of the file.
});
files is an instance of Ext.space.files.Collection. See Ext.space.files.Collection for a complete list of file operations.
This module also allows you to run queries across all of an application's Collections:
Ext.space.SecureFiles.query({ name: "*.txt" }).then(function(files) {
// got 'em
});
Parse the most likely compression encoding from the given filename.
name : String
File name to parse
Compression encoding, or "" if unknown
Create a function that caches query results in a dummy collection.
Function that takes a query result and caches it in a dummy collection (necessary to run queries without collections and still allow various file operations to work correctly)
Remove a file from any loaded collections.
When a file gets overwritten by some operation, the object in memory needs to be removed from any collections we've loaded; this function traverses through every collection this module is tracking and does just that.
key : String
File key
Compress the provided files into an archive.
Ext.space.SecureFiles.compress({
files: arrayOfFileObjects,
archiveName: "somefiles.zip"
}).then(function(file) {
// do something with the archive file
});
// or specify more options:
Ext.space.SecureFiles.compress({
files: arrayOfFileObjects,
archiveName: "somefiles.blob",
path: "myArchivePath",
type: "zip"
}).then(function(file) {
// do something with the archive file
});

archiveName : String
Name of the archive file to create
path : String (optional)
Path into which to save the archive; defaults to ""
type : String (optional)
Compression type ("zip", "zip", "bzip2", "rar"); if this is omitted, the system will attempt to determine the compression type from the archiveName, and if it cannot be determined, defaults to "zip".
Promise that resolves with the Ext.space.files.File object for the new archive.
Get a collection by name. Collections are automatically created if they do not exist, and multiple requests for collections with the same name will all return the same collection object.
name : String
The name of the collection to get.
the secure collection.
Create a file from its file Key. The collection the file belongs to is updated If the File's Collection is not in memory then it is automatically created.
key : String
The key of the file on the file system.
Query the application's file system for files that match the given criteria.
The query is a dictionary with data against which to match files. The fields supported are:
name
: "exactName.txt", "*.txt", etc...type
: MIME type ("text/plain", etc...)createdBefore
: Date objectcreatedAfter
: Date objectmodifiedBefore
: Date objectmodifiedAfter
: Date objectThe query will combine the criteria specified and produce an array of matching files. If you omit the query completely, the query operation will return an array of all files in the collection.
The options
is a dictionary describing how you want the results to be presented:
fetch
