Ext.slider.Multixtype: multislider

@deprecated 4.0 Replaced by {link:#addCls} Adds a CSS class to the top level element representing this component.

Parameters

• cls : String

  The CSS class name to add

Returns

• Ext.Component   

  Returns the Component to allow method chaining.

Adds a CSS class to the top level element representing this component.

Parameters

• cls : String

  The CSS class name to add

Returns

• Ext.Component   

  Returns the Component to allow method chaining.

Adds a cls to the uiCls array, which will also call addUIClsToElement and adds to all elements of this component.

Parameters

• cls : String/Array

  A string or an array of strings to add to the uiCls

Returns

• void   

Adds the specified events to the list of events which this Observable may fire.

Parameters

• o : Object/String

  Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters.

• : String

  [additional] Optional additional event names if multiple event names are being passed as separate parameters. Usage:

  this.addEvents('storeloaded', 'storecleared');
  

Returns

• void   

Appends an event handler to this object.

Parameters

• eventName : String

  The name of the event to listen for. May also be an object who's property names are event names. See

• handler : Function

  The method the event invokes.

• scope : Object

  (optional) The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

• options : Object

  (optional) An object containing handler configuration. properties. This may contain any of the following properties:

  • scope : Object
    The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.
  • delay : Number
    The number of milliseconds to delay the invocation of the handler after the event fires.
  • single : Boolean
    True to add a handler to handle just the next firing of the event, and then remove itself.
  • buffer : Number
    Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.
  • target : Observable
    Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.
  • element : String
    This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

    This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

    new Ext.panel.Panel({
        title: 'The title',
        listeners: {
            click: this.handlePanelClick,
            element: 'body'
        }
    });
    

    When added in this way, the options available are the options applicable to Ext.core.Element.addListener

  
  

  Combining Options
  Using the options argument, it is possible to combine different types of listeners:
  
  A delayed, one-time listener.

  myPanel.on('hide', this.handleClick, this, {
  single: true,
  delay: 100
  });

  Attaching multiple handlers in 1 call
  The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

  myGridPanel.on({
      cellClick: this.onCellClick,
      mouseover: this.onMouseOver,
      mouseout: this.onMouseOut,
      scope: this // Important. Ensure "this" is correct during handler execution
  });
  

  .

Returns

• Component   

  this

Perform custom animation on this object.

This method is applicable to both the the Component class and the Element class. It performs animated transitions of certain properties of this object over a specified timeline.

The sole parameter is an object which specifies start property values, end property values, and properties which describe the timeline. Of the properties listed below, only to is mandatory.

Properties include

• from
  An object which specifies start values for the properties being animated. If not supplied, properties are animated from current settings. The actual properties which may be animated depend upon ths object being animated. See the sections below on Element and Component animation.
• to
  An object which specifies end values for the properties being animated.
• duration
  The duration in milliseconds for which the animation will run.
• easing
  A string value describing an easing type to modify the rate of change from the default linear to non-linear. Values may be one of:

  • ease
  • easeIn
  • easeOut
  • easeInOut
  • backIn
  • backOut
  • elasticIn
  • elasticOut
  • bounceIn
  • bounceOut
• keyframes
  This is an object which describes the state of animated properties at certain points along the timeline. it is an object containing properties who's names are the percentage along the timeline being described and who's values specify the animation state at that point.
• listeners
  This is a standard listeners configuration object which may be used to inject behaviour at either the beforeanimate event or the afteranimate event.

Animating an Element

• x
  The page X position in pixels.
• y
  The page Y position in pixels
• left
  The element's CSS left value. Units must be supplied.
• top
  The element's CSS top value. Units must be supplied.
• width
  The element's CSS width value. Units must be supplied.
• height
  The element's CSS height value. Units must be supplied.
• scrollLeft
  The element's scrollLeft value.
• scrollTop
  The element's scrollLeft value.
• opacity
  The element's opacity value. This must be a value between 0 and 1.

Be aware than animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to directly animate certain properties of Components.

Animating a Component

• x
  The Component's page X position in pixels.
• y
  The Component's page Y position in pixels
• left
  The Component's left value in pixels.
• top
  The Component's top value in pixels.
• width
  The Component's width value in pixels.
• width
  The Component's width value in pixels.
• dynamic
  Specify as true to update the Component's layout (if it is a Container) at every frame of the animation. Use sparingly as laying out on every intermediate size change is an expensive operation.

For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:

myWindow = Ext.create('Ext.window.Window', {
    title: 'Test Component animation',
    width: 500,
    height: 300,
    layout: {
        type: 'hbox',
        align: 'stretch'
    },
    items: [{
        title: 'Left: 33%',
        margins: '5 0 5 5',
        flex: 1
    }, {
        title: 'Left: 66%',
        margins: '5 5 5 5',
        flex: 2
    }]
});
myWindow.show();
myWindow.header.el.on('click', function() {
    myWindow.animate({
        to: {
            width: (myWindow.getWidth() == 500) ? 700 : 500,
            height: (myWindow.getHeight() == 300) ? 400 : 300,
        }
    });
});

For performance reasons, by default, the internal layout is only updated when the Window reaches its final "to" size. If dynamic updating of the Window's child Components is required, then configure the animation with dynamic: true and the two child items will maintain their proportions during the animation.

Parameters

• config : Object

  An object containing properties which describe the animation's start and end states, and the timeline of the animation.

Returns

• Object   

  this

Applies the state to the object. This should be overridden in subclasses to do more complex state operations. By default it applies the state properties onto the current object.

Parameters

• state : Object

  The state

Returns

• void   

A utility for grouping a set of modifications which may trigger value changes into a single transaction, to prevent excessive firing of change events. This is useful for instance if the field has sub-fields which are being updated as a group; you don't want the container field to check its own changed state for each subfield change.

Parameters

• fn : Object

  A function containing the transaction code

Returns

• void   

Occurs before componentLayout is run. Returning false from this method will prevent the componentLayout from being executed.

Parameters

• adjWidth : Number

  The box-adjusted width that was set

• adjHeight : Number

  The box-adjusted height that was set

• isSetSize : Boolean

  Whether or not the height/width are stored on the component permanently

• layoutOwner : Ext.Component

  Component which sent the layout. Only used when isSetSize is false.

Returns

• void   

Bubbles up the component/container heirarchy, calling the specified function with each component. The scope (this) of function call will be the scope provided or the current component. The arguments to the function will be the args provided or the current component. If the function returns false at any point, the bubble is stopped.

Parameters

• fn : Function

  The function to call

• scope : Object

  (optional) The scope of the function (defaults to current node)

• args : Array

  (optional) The args to call the function with (default to passing the current component)

Returns

• Ext.Component   

  this

Starts capture on the specified Observable. All events will be passed to the supplied function with the event name + standard signature of the event before the event is fired. If the supplied function returns false, the event will not fire.

Parameters

• o : Observable

  The Observable to capture events from.

• fn : Function

  The function to call when an event is fired.

• scope : Object

  (optional) The scope (this reference) in which the function is executed. Defaults to the Observable firing the event.

Returns

• void   

Center this Component in its container.

Returns

• Component   

  this

Checks whether the value of the field has changed since the last time it was checked. If the value has changed, it:

1. Fires the change event,
2. Performs validation if the validateOnChange config is enabled, firing the validationchange event if the validity has changed, and
3. Checks the dirty state of the field and fires the dirtychange event if it has changed.

Returns

• void   

Checks the isDirty state of the field and if it has changed since the last time it was checked, fires the dirtychange event.

Returns

• void   

Clear any invalid styles/messages for this field.

Note: this method does not cause the Field's validate or isValid methods to return true if the value does not pass validation. So simply clearing a field's errors will not necessarily allow submission of forms submitted with the Ext.form.action.Submit.clientValidation option set.

Returns

• void   

Removes all listeners for this object including the managed listeners

Returns

• void   

Removes all managed listeners for this object.

Returns

• void   

Clone the current component using the original config values passed into this instance by default.

Parameters

• overrides : Object

  A new config containing any properties to override in the cloned version. An id property can be passed on this object, otherwise one will be generated to avoid duplicates.

Returns

• Ext.Component   

  clone The cloned copy of this component

Destroys this stateful object.

Returns

• void   

Disable the component.

Parameters

• silent : Boolean

  Passing true, will supress the 'disable' event from being fired.

Returns

• void   

Handles autoRender. Floating Components may have an ownerCt. If they are asking to be constrained, constrain them within that ownerCt, and have their z-index managed locally. Floating Components are always rendered to document.body

Returns

• void   

This method needs to be called whenever you change something on this component that requires the Component's layout to be recalculated.

Parameters

• width : Object
• height : Object
• isSetSize : Object
• ownerCt : Object

Returns

• Ext.container.Container   

  this

Moves this floating Component into a constrain region.

By default, this Component is constrained to be within the container it was added to, or the element it was rendered to.

An alternative constraint may be passed.

Parameters

• constrainTo : Mixed

  Optional. The Element or Region into which this Component is to be constrained.

Returns

• void   

Enable the component

Parameters

• silent : Boolean

  Passing false will supress the 'enable' event from being fired.

Returns

• void   

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

Example:

Ext.override(Ext.form.field.Base, {
//  Add functionality to Field's initComponent to enable the change event to bubble
initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
    this.enableBubble('change');
}),

//  We know that we want Field's events to bubble directly to the FormPanel.
getBubbleTarget : function() {
    if (!this.formPanel) {
        this.formPanel = this.findParentByType('form');
    }
    return this.formPanel;
}
});

var myForm = new Ext.formPanel({
title: 'User Details',
items: [{
    ...
}],
listeners: {
    change: function() {
        // Title goes red if form has been modified.
        myForm.header.setStyle('color', 'red');
    }
}
});

Parameters

• events : String/Array

  The event name to bubble, or an Array of event names.

Returns

• void   

Only relevant if the instance's isFileUpload method returns true. Returns a reference to the file input DOM element holding the user's selected file. The input will be appended into the submission form and will not be returned, so this method should also create a replacement.

Returns

• HTMLInputElement   

This method finds the topmost active layout who's processing will eventually determine the size and position of this Component.

This method is useful when dynamically adding Components into Containers, and some processing must take place after the final sizing and positioning of the Component has been performed.

Returns

• void   

Find a container above this component at any level by a custom function. If the passed function returns true, the container will be returned.

Parameters

• fn : Function

  The custom function to call with the arguments (container, this component).

Each subclass should override or augment the return value to provide their own errors.

Parameters

• value : Mixed

  The value to get errors for (defaults to the current field value)

Returns

• Array   

  All error messages for this field; an empty Array if none.

  The loader instance, null if it doesn't exist.

Returns the value(s) that should be saved to the Ext.data.Model instance for this field, when Ext.form.Basic.updateRecord is called. Typically this will be an object with a single name-value pair, the name being this field's name and the value being its current data value. More advanced field implementations may return more than one name-value pair. The returned values will be saved to the corresponding field names in the Model.

Note that the values returned from this method are not guaranteed to have been successfully validated.

  The current state

Gets the state id for this object.

Returns

• String   

  The state id, null if not found.

Returns the parameter(s) that would be included in a standard form submit for this field. Typically this will be an object with a single name-value pair, the name being this field's name and the value being its current stringified value. More advanced field implementations may return more than one name-value pair.

Note that the values returned from this method are not guaranteed to have been successfully validated.

Returns

Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the Ext.Component header.

If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.

Example usage:

var t = new Ext.form.field.Text();
alert(t.getXTypes());  // alerts 'component/field/textfield'

Returns

• String   

  The xtype hierarchy string

Tells whether the field currently has an active error message. This does not trigger validation on its own, it merely looks for any message that the component may already hold.

Parameters

• eventName : String

  The name of the event to check for

Returns

• Boolean

  The selector string to test against.

Returns

• Boolean   

  True if this Component matches the selector.

Determines whether this component is the descendant of a particular container.

Parameters

• container : Ext.Container

Returns

• Boolean   

  isDescendant

Returns true if the value of this Field has been changed from its originalValue. Will always return false if the field is disabled.

Note that if the owning form was configured with trackResetOnLoad then the originalValue is updated when the values are loaded by Ext.form.Basic.setValues.

Returns

• Boolean   

  True if this field has been changed from its original value (and is not disabled), false otherwise.

Method to determine whether this Component is currently disabled.

Returns

• Boolean   

  the disabled state of this Component.

Method to determine whether this Component is draggable.

Returns

• Boolean   

  the draggable state of this component.

Method to determine whether this Component is droppable.

Parameters

• value1 : Mixed

  The first value to compare

• value2 : Mixed

  The second value to compare

Returns

• Boolean   

  True if the values are equal, false if inequal.

Returns whether this Field is a file upload field; if it returns true, forms will use special techniques for submitting the form via AJAX. See Ext.form.Basic.hasUpload for details. If this returns true, the extractFileInput method must also be implemented to return the corresponding file input element.

Returns

• Boolean   

Method to determine whether this Component is floating.

Returns

• Boolean   

  the floating state of this component.

Method to determine whether this Component is currently set to hidden.

Returns

• Boolean   

  the hidden state of this Component.

Returns whether or not the field value is currently valid by validating the field's current value. The validitychange event will not be fired; use validate instead if you want the event to fire. Note: disabled fields are always treated as valid.

Implementations are encouraged to ensure that this method does not have side-effects such as triggering error message display.

Returns

• Boolean   

  True if the value is valid, else false

Returns true if this component is visible.

Parameters

• deep : Boolean

  .

  Optional. Pass true to interrogate the visibility status of all parent Containers to determine whether this Component is truly visible to the user.

  Generally, to determine whether a Component is hidden, the no argument form is needed. For example when creating dynamically laid out UIs in a hidden Container before showing them.

Returns

• Boolean   

  True if this component is visible, false otherwise.

Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended from the xtype (default) or whether it is directly of the xtype specified (shallow = true).

If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.

For a list of all available xtypes, see the Ext.Component header.

Example usage:

var t = new Ext.form.field.Text();
var isText = t.isXType('textfield');        // true
var isBoxSubclass = t.isXType('field');       // true, descended from Ext.form.field.Base
var isBoxInstance = t.isXType('field', true); // false, not a direct Ext.form.field.Base instance

Parameters

• xtype : String

  The xtype to check for this Component

• shallow : Boolean

  (optional) False to check whether this Component is descended from the xtype (this is the default), or true to check whether this Component is directly of the specified xtype.

Returns

• Boolean   

  True if this component descends from the specified xtype, false otherwise.

Display one or more error messages associated with this field, using msgTarget to determine how to display the messages and applying invalidCls to the field's UI element.

Note: this method does not cause the Field's validate or isValid methods to return false if the value does pass validation. So simply marking a Field as invalid will not prevent submission of forms submitted with the Ext.form.action.Submit.clientValidation option set.

Parameters

• errors : String/Array

  The validation message(s) to display.

Returns

• void   

Returns the next node in the Component tree in tree traversal order.

Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree to attempt to find a match. Contrast with pnextSibling.

Parameters

• selector : String

  Optional A ComponentQuery selector to filter the following nodes.

• includeSelf : Object

Returns

• void   

  The next node (or the next node which matches the selector). Returns null if there is no matching node.

Returns the next sibling of this Component.

Optionally selects the next sibling which matches the passed ComponentQuery selector.

May also be refered to as next()

Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with nextNode

Parameters

• selector : String

  Optional A ComponentQuery selector to filter the following items.

Returns

• void   

  The next sibling (or the next sibling which matches the selector). Returns null if there is no matching sibling.

Sets observability on the passed class constructor.

This makes any event fired on any instance of the passed class also fire a single event through the class allowing for central handling of events on many instances at once.

Usage:

Ext.util.Observable.observe(Ext.data.Connection);
Ext.data.Connection.on('beforerequest', function(con, options) {
    console.log('Ajax request made to ' + options.url);
});

Parameters

• c : Function

  The class constructor to make observable.

• listeners : Object

  An object containing a series of listeners to add. See addListener.

Returns

• void   

Appends an event handler to this object (shorthand for addListener.)

Parameters

• eventName : String

  The type of event to listen for

• handler : Function

  The method the event invokes

• scope : Object

  (optional) The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

• options : Object

  (optional) An object containing handler configuration.

Returns

• void   

Returns the previous node in the Component tree in tree traversal order.

Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree in reverse order to attempt to find a match. Contrast with previousSibling.

Parameters

• selector : String

  Optional. A ComponentQuery selector to filter the preceding nodes.

• includeSelf : Object

Returns

• void   

  The previous node (or the previous node which matches the selector). Returns null if there is no matching node.

Returns the previous sibling of this Component.

Optionally selects the previous sibling which matches the passed ComponentQuery selector.

May also be refered to as prev()

Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with previousNode

Parameters

• selector : String

  Optional. A ComponentQuery selector to filter the preceding items.

Returns

• void   

  The previous sibling (or the previous sibling which matches the selector). Returns null if there is no matching sibling.

Performs any necessary manipulation of a raw field value to prepare it for conversion and/or validation, for instance stripping out ignored characters. In the base implementation it does nothing; individual subclasses may override this as needed.

Parameters

• value : Mixed

  The unprocessed string value

Returns

• Mixed   

  The processed string value

Converts a raw input field value into a mixed-type value that is suitable for this particular field type. This allows controlling the normalization and conversion of user-entered values into field-type-appropriate values, e.g. a Date object for Ext.form.field.Date, and is invoked by getValue.

It is up to individual implementations to decide how to handle raw values that cannot be successfully converted to the desired object type.

See valueToRaw for the opposite conversion.

The base implementation does no conversion, returning the raw value untouched.

Parameters

• rawValue : Mixed

Returns

• Mixed   

  The converted value.

Returns

• void   

Removes all added captures from the Observable.

Parameters

• o : Observable

  The Observable to release

Returns

• void   

Removes a CSS class from the top level element representing this component.

Parameters

• className : Object

Returns

• Ext.Component   

  Returns the Component to allow method chaining.

Removes a cls to the uiCls array, which will also call removeUIClsToElement and removes it from all elements of this component.

Parameters

Returns

• void   

Removes an event handler.

Parameters

  Optional. If the ename parameter was an event name, this is the handler function.

• scope : Object

  Optional. If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

Returns

• void   

Resets the current field value to the originally loaded value and clears any validation messages. See Ext.form.Basic.trackResetOnLoad

Returns

• void   

Resets the field's originalValue property so it matches the current value. This is called by Ext.form.Basic.setValues if the form's trackResetOnLoad property is set to true.

Returns

Returns

• Ext.core.Element   

  The Element

This method is called internally by Ext.ZIndexManager to signal that a floating Component has either been moved to the top of its zIndex stack, or pushed from the top of its zIndex stack.

Sets the active error message to the given string. This replaces the entire error message contents with the given string. Also see setActiveErrors which accepts an Array of messages and formats them according to the activeErrorsTpl.

Parameters

• msg : String

  The error message

Returns

• void   

Set the active error message to an Array of error messages. The messages are formatted into a single message string using the activeErrorsTpl. Also see setActiveError which allows setting the entire error contents with a single string.

Parameters

• errors : Array

  The error messages

Returns

• void   

Sets the overflow on the content element of the component.

Parameters

• scroll : Boolean

  True to allow the Component to auto scroll.

Returns

• Ext.Component   

  this

Returns whether or not the field value is currently valid by validating the field's current value, and fires the validitychange event if the field's validity has changed since the last validation. Note: disabled fields are always treated as valid.

Custom implementations of this method are allowed to have side-effects such as triggering error message display. To validate without side-effects, use isValid.

Returns

• Boolean   

  True if the value is valid, else false

Uses getErrors to build an array of validation errors. If any errors are found, they are passed to markInvalid and false is returned, otherwise true is returned.

Previously, subclasses were invited to provide an implementation of this to process validations - from 3.2 onwards getErrors should be overridden instead.

Parameters

• value : Mixed

  The value to validate

Returns

• Boolean   

  True if all validations passed, false if one or more failed

Converts a mixed-type value to a raw representation suitable for displaying in the field. This allows controlling how value objects passed to setValue are shown to the user, including localization. For instance, for a Ext.form.field.Date, this would control how a Date object passed to setValue would be converted to a String for display in the field.

See rawToValue for the opposite conversion.

The base implementation simply does a standard toString conversion, and converts empty values to an empty string.

Parameters

• value : Mixed

  The mixed-type value to convert to the raw representation.

Returns

• Mixed   

  The converted raw value.
