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 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.
Send log messages to the console, filtered by log level.
The log levels available are properties on this object:
Ext.space.Logger.LOG // "LOG"
Ext.space.Logger.ERROR // "ERROR"
Ext.space.Logger.WARN // "WARN"
Ext.space.Logger.INFO // "INFO" (default)
Ext.space.Logger.DEBUG // "DEBUG"
Each log level has a corresponding method that logs its arguments to the console
using the appropriate method on the console, optionally prefixed by the name of
the log level. Messages logged with Ext.space.Logger.log(...) are always logged
regardless of the current log level, but the rest take it into account.
var logger = Ext.space.Logger;
logger.level(); // "INFO" by default
logger.log("This message is always logged no matter what");
logger.info("Info level message, gets skipped.");
logger.level(logger.DEBUG);
logger.info("Info level message, gets shown this time.");
logger.usePrefix = true;
logger.warn("This one will be prefixed by 'WARN'");
logger.error("Multiple", ["argument", "error"], {prop: "message"});
Note that the "ERROR" log level doesn't throw actual errors; that's up to the application itself.
You can also track custom application-defined events (defined as a collection of basically arbitrary strings: category, action, label (optional), extra (optional)) with Ext.space.Logger.logEvent(). These get logged at the level provided to Ext.space.Logger.eventLevel(...) (default Ext.space.Logger.INFO), and also submitted to the Sencha Web Application Manager server for report generation in the administration console.

Send a custom event to the server.
Events are a somewhat free-form set of arbitrary strings that facilitate
grouping in administrative reports. They're required to have a category and
action and can optionally also be given a label and/or extra data. Sencha
Web Application Client will attempt to submit the event data to the server,
and if the server is not accessible (for example, if the user is offline), it
will store the event for submission later.
Ext.space.Logger.logEvent({
category: "Contact",
action: "Contact form submission",
label: "From footer",
extra: "[email protected]"
}).then(function() {
// do something, if you want
}, function(error) {
// something went wrong, nothing worked, everything is terrible
});
kwArgs : Object< / a>
Custom event definition
category : String
Event category name
action : String
Event action name
label : String (optional)
Event label
extra : String (optional)
Extra event information
