Config Options | Defined By | |
---|---|---|
allowDomMove : Boolean
Whether the component can move the Dom node when rendering (defaults to true).
|
Component | |
applyTo : Mixed The id of the node, a DOM node or an existing Element corresponding to a DIV that is already present in the document ...
The id of the node, a DOM node or an existing Element corresponding to a DIV that is already present in the document that specifies some structural markup for this component. When applyTo is used, constituent parts of the component can also be specified by id or CSS class name within the main element, and the component being created may attempt to create its subcomponents from that markup if applicable. Using this config, a call to render() is not required. If applyTo is specified, any value passed for renderTo will be ignored and the target element's parent node will automatically be used as the component's container.

Component | |
autoHeight : Boolean True to use height:'auto', false to use fixed height (defaults to false). Note: Although many components inherit this...
True to use height:'auto', false to use fixed height (defaults to false). Note: Although many components inherit this config option, not all will function as expected with a height of 'auto'. Setting autoHeight:true means that the browser will manage height based on the element's contents, and that Ext will not manage it at all.
|
BoxComponent | |
autoShow : Boolean True if the component should check for hidden classes (e.g. 'x-hidden' or 'x-hide-display') and remove them on render...
True if the component should check for hidden classes (e.g. 'x-hidden' or 'x-hide-display') and remove them on render (defaults to false).

True to use width:'auto', false to use fixed width (defaults to false). Note: Although many components inherit this config option, not all will function as expected with a width of 'auto'. Setting autoWidth:true means that the browser will manage width based on the element's contents, and that Ext will not manage it at all.

An optional extra CSS class that will be added to this component's container (defaults to ''). This can be useful for adding customized styles to the container or any of its children using standard CSS rules.
|
Component | |
disabled : Boolean
Render this component disabled (default is false).
|
Component | |
disabledClass : String
CSS class added to the component when it is disabled (defaults to "x-item-disabled").
|
Component | |
fieldLabel : String The label text to display next to this Component (defaults to '') This config is only used when this Component is ren...
The label text to display next to this Component (defaults to '')
This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use: |
Component | |
height : Number
The height of this component in pixels (defaults to auto).
|
BoxComponent | |
Render this component hidden (default is false).
|
hidden : Boolean Component | |
hideLabel : Boolean True to completely hide the label element (defaults to false). By default, even if you do not specify a fieldLabel th...
True to completely hide the label element (defaults to false). By default, even if you do not specify a fieldLabel the space will still be reserved so that the field will line up with other fields that do have labels. Setting this to true will cause the field to not reserve that space.
This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use: |
Component | |
hideMode : String How this component should be hidden. Supported values are "visibility" (css visibility), "offsets" (negative offset p...
How this component should be hidden. Supported values are "visibility" (css visibility), "offsets" (negative offset position) and "display" (css display) - defaults to "display". For Containers which may be hidden and shown as part of a card layout Container such as a TabPanel, it is recommended that hideMode is configured as "offsets". This ensures that hidden Components still have height and width so that layout managers can perform measurements when calculating layouts. |
Component | |
hideParent : Boolean True to hide and show the component's container when hide/show is called on the component, false to hide and show the...
True to hide and show the component's container when hide/show is called on the component, false to hide and show the component itself (defaults to false). For example, this can be used as a shortcut for a hide button on a window by setting hide:true on the button when adding it to its parent container.
|
Component | |
id : String The unique id of this component (defaults to an auto-assigned id). You should assign an id if you need to be able to ...
The unique id of this component (defaults to an auto-assigned id). You should assign an id if you need to be able to access the component later and you do not have an object reference available (e.g., using Ext.ComponentMgr.getCmp). Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.
|
Component | |
itemCls : String An additional CSS class to apply to the wrapper's form item element of this field (defaults to the container's itemCl...
An additional CSS class to apply to the wrapper's form item element of this field (defaults to the container's itemCls value if set, or ''). Since it is applied to the item wrapper, it allows you to write standard CSS rules that can apply to the field, the label (if specified) or any other element within the markup for the field.
This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager. Example use: |
Component | |
labelSeparator : String The standard separator to display after the text of each form label (defaults to the value of Ext.layout.FormLayout.l...
The standard separator to display after the text of each form label (defaults to the value of Ext.layout.FormLayout.labelSeparator, which is a colon ':' by default). To display no separator for this field's label specify empty string ''.

An optional extra CSS class that will be added to this component's Element when the mouse moves over the Element, and removed when the mouse moves out. (defaults to ''). This can be useful for adding customized "active" or "hover" styles to the component or any of its children using standard CSS rules.

An object or array of objects that will provide custom functionality for this component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.Component. When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality.

An array of events that, when fired, should trigger this component to save its state (defaults to none). These can be any types of events supported by this component, including browser or custom events (e.g., ['click', 'customerchange']).
See stateful for an explanation of saving and restoring Component state. |

The unique id for this component to use for state management purposes (defaults to the component id if one was set, otherwise null if the component is using a generated id).
See stateful for an explanation of saving and restoring Component state. |
Component | |
stateful : Boolean A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startu...
A flag which causes the Component to attempt to restore the state of internal properties from a saved state on startup. The component must have either a stateId or id assigned for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a component. For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available. To set the state provider for the current page: Components attempt to save state when one of the events listed in the stateEvents configuration fires. You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events |

The registered xtype to create. This config option is not used when passing a config object into a constructor. This config option is used only when lazy instantiation is being used, and a child item of a Container is being specified not as a fully instantiated Component, but as a Component config object. The xtype will be looked up at render time up to determine what type of child Component to create.
The predefined xtypes are listed here. If you subclass Components to create your own Components, you may register them using Ext.ComponentMgr.registerType in order to be able to take advantage of lazy instantiation and rendering. |
Component | |
y : Number
The local y (top) coordinate for this component if contained within a positioning container.

render( [Element/HTMLElement/String container ], [String/Number position ] ) : void Render this Component into the passed HTML element.
If you are using a Container object to house this Component, then...
Render this Component into the passed HTML element. If you are using a Container object to house this Component, then do not use the render method. A Container's child Components are rendered by that Container's layout manager when the Container is first rendered. Certain layout managers allow dynamic addition of child components. Those that do include Ext.layout.CardLayout, Ext.layout.AnchorLayout, Ext.layout.FormLayout, Ext.layout.TableLayout. If the Container is already rendered when a new child Component is added, you may need to call the Container's doLayout to refresh the view which causes any unrendered child Components to be rendered. This is required so that you can add multiple child components if needed while only refreshing the layout once. When creating complex UIs, it is important to remember that sizing and positioning of child items is the responsibility of the Container's layout manager. If you expect child items to be sized in response to user interactions, you must configure the Container with a layout manager which creates and manages the type of layout you have in mind. Omitting the Container's layout config means that a basic layout manager is used which does nothing but render child components sequentially into the Container. No sizing or positioning will be performed in this situation.
