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.
classInstance.method1().method2().etc();false is returned from
an event handler- Indicates a framework class

- 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

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.
Background color to apply to the body element. If set to transparent or 'none' no background-color style will be set on the body element.
Defaults to:
transparent
True to add font-smoothing styles to all components
Defaults to:
true
The default font-family to be used throughout the theme.
Defaults to:
helvetica, arial, verdana, sans-serif
The default font-weight to be used throughout the theme.
Defaults to:
normal
The default font-weight for bold font to be used throughout the theme.
Defaults to:
bold
Flag to ensure GridField rules only get set once
Defaults to:
false
default file extension to use for images (defaults to 'png').
Defaults to:
'png'
True to include Internet Explorer specific rules for IE9 and lower. IE10 and up are considered to be "modern" browsers, and as such do not need any of the CSS hacks required for IE9 and below. Setting this property to false will result in a significantly smaller CSS file size, and may also result in a slight performance improvement, because the browser will have fewer rules to process.
Defaults to:
true
True to include files which are not found when compiling your SASS
Defaults to:
true
True to include right-to-left style rules. This variable gets set to true automatically for rtl builds. You should not need to ever assign a value to this variable, however it can be used to suppress rtl-specific rules when they are not needed. For example: @if $include-rtl { .x-rtl.foo { margin-left: $margin-right; margin-right: $margin-left; } }
Defaults to:
true
True to include rules for rounded corners produced by the slicer. Enables emulation of CSS3 border-radius in browsers that do not support it.
Defaults to:
$include-ie
True to include rules for background gradients produced by the slicer. Enables emulation of CSS3 background-gradient in browsers that do not support it.
Defaults to:
$include-ie
The default line-height to be used throughout the theme.
Defaults to:
normal
The prefix to be applied to all CSS selectors. If this is changed, it must also be changed in your JavaScript application.
Defaults to:
'x-'
True to use a relative image path for all new UIs. If true, the path will be "../images/". It can also be a string of the path value. It defaults to false, which means it will look for the images in the ExtJS SDK folder.
Defaults to:
false
default file extension to use for slicer images (defaults to 'gif').
Defaults to:
'gif'
The base path relative to the CSS output directory to use for theme resources. For example if the theme's images live one directory up from the generated CSS output in a directory named 'foo/images/', you would need to set this variable to '../foo/' in order for the image paths in the CSS output to be generated correctly. By default this is the same as the CSS output directory.
Defaults to:
''
Creates a background gradient.
Example usage: .foo { @include background-gradient(#808080, matte, left); }
$bg-color : Color
The background color of the gradient
$type : String/List (optional)
The type of gradient to be used. Can either
be a String which is a predefined gradient name, or it can can be a list of color stops.
If null is passed, this mixin will still set the background-color to $bg-color.
The available predefined gradient names are:
Each of these gradient names corresponds to a function named linear-gradient[name]. Themes can override these functions to customize the color stops that they return. For example, to override the glossy-button gradient function add a function named "linear-gradient-glossy-button" to a file named "sass/etc/mixins/background-gradient.scss" in your theme. The function should return the result of calling the Compass linear-gradient function with the desired direction and color-stop information for the gradient. For example:
@function linear-gradient-glossy-button($direction, $bg-color) {
@return linear-gradient($direction, color_stops(
mix(#fff, $bg-color, 10%),
$bg-color 50%,
mix(#000, $bg-color, 5%) 51%,
$bg-color
));
}
Defaults to: $base-gradient
$direction : String (optional)
The direction of the gradient. Can either be
top or left.
Defaults to: top
adds a css outline to an element with compatibility for IE8/outline-offset NOTE: the element receiving the outline must be positioned (either relative or absolute) in order for the outline to work in IE8
$width : Number (optional)
The width of the outline
Defaults to: 1px
$style : String (optional)
The style of the outline
Defaults to: solid
$color : color (optional)
The color of the outline
Defaults to: #000
$offset : Number (optional)
The offset of the outline
Defaults to: 0
$border-width : Number/list (optional)
The border-width of the element receiving the outline. Required in order for outline-offset to work in IE8
Defaults to: 0
Includes a google webfont for use in your theme.
$font-name : String
The name of the font. If the font name contains spaces use "+" instead of space.
$font-weights : String (optional)
Comma-separated list of font weights to include.
Example usage:
@include google-webfont(
$font-name: Exo,
$font-weights: 200 300 400
);
Outputs:
@import url(//fonts.googleapis.com/css?family=Exo:200,300,400);
Defaults to: 400
