Button class in this case. This may be overridden in subclasses when special processing needs to be applied to child creation. 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. 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. Within the history config menu you will also see a listing of your recent page visits.

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. 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. 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:.

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. 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. Mixin Ext. Labelable Ext. Field Ext. Accessible Ext. Bindable Ext.

ComponentDelegation Ext. Identifiable Ext. Inheritable Ext. Keyboard Ext. Observable Ext. Stateful Ext. Animate Ext. ElementContainer Ext. Floating Ext.

Focusable Ext. Positionable Ext. FileButton Ext. A file upload field which has custom styling and allows control over the button text and other features of Ext. Text like empty text. It uses a hidden file input element behind the scenes to allow user selection of a file and to perform the actual upload during form submit. Because there is no secure cross-browser way to programmatically set the value of a file input, the standard Field setValue method is not implemented.

The getValue method will return a value that is browser-dependent; some have just the file name, some have a full path, some use a fake path. Basic hasUpload for details. An optional list of file MIME types accepted by this field.

An incrementing numeric counter indicating activation index for use by the zIndexManager to sort its stack. If specified, then the component will be displayed with this value as its active error when first rendered.

Use setActiveError or unsetActiveError to change it after component creation. Gets the active error message for this component, if any. This does not trigger validation on its own, it merely returns any message that the component may already hold. 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. Note that this only updates the error message element's text and attributes, you'll have to call doComponentLayout to actually update the field's layout to match. If the field extends Ext. Base you should call markInvalid instead. Otherwise, it renders each message as an item in an unordered list.

An optional string or XTemplate configuration to insert in the field markup at the end of the input containing element. If an XTemplate is used, the component's render data serves as the context. An optional string or XTemplate configuration to insert in the field markup after the label text.

An optional string or XTemplate configuration to insert in the field markup after the label element. An optional string or XTemplate configuration to insert in the field markup after the subTpl markup. By default, when the alignTo method is called, a floating component will scroll to keep aligned with the anchoring element if the anchoring element is part of the scroll.

If this is not necessary, and the alignTo is a one-off operation then set this config to false. A Component or Element by which to position this component according to the defaultAlign.

Defaults to the owning Container. If true , then a blank value is always taken to be valid regardless of any vtype validation that may be applied. If vtype validation must still be applied to blank values, configure validateBlank as true ;. Specify false to automatically trim the value before validating the whether the value is blank.

Setting this to false automatically sets allowBlank to false. A flag indicating that this component should be on the top of the z-index stack for use by the zIndexManager to sort its stack. This may be a positive number to prioritize the ordering of multiple visible always on top components. This may be set to a negative number to prioritize a component to the bottom of the z-index stack.

This configuration option is to be applied to child items of a container managed by an Ext. This value is what tells the layout how an item should be anchored to the container. The following types of anchor values are supported:. The first anchor is the percentage width that the item should take up within the container, and the second is the percentage height.

For example:. This is a raw adjustment where the first anchor is the offset from the right edge of the container, and the second is the offset from the bottom edge. Sides : Valid values are right or r and bottom or b. Either the container must have a fixed size or an anchorSize config value defined at render time in order for these to have any effect.

Anchor values can also be mixed as needed. By default the shadow is hidden while the component is animating. Use this to set the attributes that cannot be determined by the Component's state, such as aria-live , aria-flowto , etc.

Note that this config is only meaningful at the Component rendering time, and setting it after that will do nothing. DOM selector for a child element that is to be used as description for this Component, set in aria-describedby attribute.

The selector works the same way as ariaLabelledBy. Localized announcement text for validation errors. This text will be used by Assistive Technologies such as screen readers to alert the users when field validation fails. This config is used with Ext. Defaults to: 'Input error. Optional text description for this object. This text will be announced to Assistive Technology users when the object is focused. ARIA label for this Component.

It is best to use ariaLabelledBy option instead, because screen readers prefer aria-labelledby attribute to aria-label. DOM selector for a child element that is to be used as label for this Component, set in aria-labelledby attribute. If the selector is by id , the label element can be any existing element, not necessarily a child of the main Component element.

A tag name or Ext. Helper spec used to create the Element which will encapsulate this Component. You do not normally need to specify this.

For the base classes Ext. Component and Ext. Container , this defaults to 'div'. The more complex Sencha classes use a more complex DOM structure specified by their own cfg-renderTpl s. This is intended to allow the developer to create application-specific utility Components encapsulated by different DOM elements. Example usage:. Whether to adjust the component's body width to make room for 'side' error messages.

This config is intended mainly for non- cfg-floating Components which may or may not be shown. Instead of using renderTo in the configuration, and rendering upon construction, this allows a Component to render itself upon first show.

If cfg-floating is true , the value of this config is omitted as if it is true. Specify as an element, or the ID of an element to have this Component render to a specific element upon first show. This should not be combined with overflowX or overflowY. Deprecated since version 5. This config option may only be used for cfg-floating components or components that use autoRender.

Defaults to: Ext. The base CSS class to apply to this component's element. This will also be prepended to elements within this component like Panel's body will get a class x-panel-body.

This means that if you create a subclass of Panel, and you want it to get all the Panels styling for the element and the body, you leave the baseCls x-panel and use componentCls to add specific styling for this component.

An optional string or XTemplate configuration to insert in the field markup at the beginning of the input containing element.

An optional string or XTemplate configuration to insert in the field markup before the label text. An optional string or XTemplate configuration to insert in the field markup before the label element. An optional string or XTemplate configuration to insert in the field markup before the subTpl markup. Setting this config option adds or removes data bindings for other configs.

For example, to bind the title config:. The bind expressions are presented to Ext. ViewModel bind. The ViewModel instance is determined by lookupViewModel. Note: If bind is passed as a string, it will use the Ext. Component property-defaultBindProperty for the binding. The error text to display if the allowBlank validation fails.

Defaults to: 'This field is required'. Specifies the border size for this component. The border can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10' top, right, bottom, left. For components that have no border by default, setting this won't make the border appear by itself.

You also need to specify border color and style:. Specify optional custom button Ext. Button config eg. The number of pixels of space reserved between the button and the text field. True to display the file upload field as a button with no visible text field.

If true, all inherited Text members will still be available. The button text to display on the upload button. Note that if you supply a value for buttonConfig , the buttonConfig. Defines a timeout in milliseconds for buffering checkChangeEvents that fire in rapid succession. Defaults to 50 milliseconds.

A list of event names that will be listened for on the field's input element , which will cause the field's value to be checked for changes. If a change is detected, the change event will be fired, followed by validation if the validateOnChange option is enabled.

Defaults to ['change', 'propertychange', 'keyup'] in Internet Explorer, and ['change', 'input', 'textInput', 'keyup', 'dragdrop'] in other browsers. This catches all the ways that field values can be changed in most supported browsers; the only known exceptions at the time of writing are:.

If you need to guarantee on-the-fly change notifications including these edge cases, you can call the checkChange method on a repeating interval, e.

TaskManager , or if the field is within a Ext. Panel , you can use the FormPanel's Ext. Panel pollForChanges configuration to set up such a task automatically. The canonical form of childEls is an object keyed by child's property name with values that are objects with the following properties. Note: childEl s in the renderTpl must be referenced in a data-ref attribute.

When using select , the property will be an instance of Ext. In all other cases, the property will be an Ext. Element or null if not found. Care should be taken when using select or selectNode to find child elements. The following issues should be considered:. This above issues are most important when using select since it returns multiple elements. True to clear the selected file value when the form this field belongs to is submitted to the server.

An optional extra CSS class that will be added to this component's Element. The value can be a string, a list of strings separated by spaces, or an array of strings. This can be useful for adding customized styles to the component or any of its children using standard CSS rules. Defines the column width inside Ext. The columnWidth property is always evaluated as a percentage and must be a decimal value greater than 0 and less than 1 e.

See the description at the top of Ext. Column for additional usage details when combining width and columnWidth configs within the layout.

The sizing and positioning of a Component's internal Elements is the responsibility of the Component's layout manager which sizes a Component's internal structure in response to the Component being sized. Generally, developers will not use this configuration as all provided Components which need their internal elements sizing Such as Ext.

Base come with their own componentLayout managers. The Ext. Auto will be used on instances of the base Ext. Component class which simply sizes the Component's encapsulating element to the height and width specified in the setSize method.

True to constrain this Components within its containing element, false to allow it to fall outside of its containing element. By default this Component will be rendered to document. To render and constrain this Component within another element specify renderTo.

An object or a string in TRBL order specifying insets from the configured constrain region within which this component must be constrained when positioning or sizing. A Ext. Region or an element from which a Region measurement will be read which is used to constrain the component. Only applies when the component is floating. This config option is used to take an existing HTML element and place it in the layout element of a new component it simply moves the specified DOM element after the Component is rendered to use as the content.

The specified HTML element is appended to the layout element of the component after any configured HTML has been inserted , and so the document will not contain this element at the time the event-render event is fired. The specified HTML element used will not participate in any layout scheme that the Component may use. It is just HTML. Layouts operate on child items.

Add either the x-hidden or the x-hidden-display CSS class to prevent a brief flicker of the content before it is rendered to the panel. A string alias, a configuration object or an instance of a ViewController for this container. Sample usage:. Returns the Ext. ViewController instance associated with this component via the controller config or setController method.

The initial set of data to apply to the tpl to update the content area of the Component. The default Ext. Element getAlignToXY anchor position value for this component relative to its alignTarget which defaults to its owning Container. If true , this component will be the default scope this pointer for events specified with string names so that the scope can be dynamically resolved.

The component will automatically become the defaultListenerScope if a controller is specified. See the introductory docs for Ext. Container for some sample usages. NOTE : This value can only be reliably set at construction time. Setting it after that time may not correctly rewire all of the potentially effected listeners. Defaults to: 'x-item-disabled'. The side of the Ext.

Panel where this component is to be docked when specified in the panel's dockedItems config. Sets the dock position of this component in its parent panel. Note that this only has effect if this item is part of the dockedItems collection of a parent that has a DockLayout note that any Panel has a DockLayout by default. Specify as true to make a cfg-floating Component draggable using the Component's encapsulating element as the drag handle. This may also be specified as a config object for the Ext.

ComponentDragger which is instantiated to perform dragging. For example to create a Component which may only be dragged around using a certain internal element as the drag handle, use the delegate option:. The CSS class to apply to an empty field to style the emptyText. This class is automatically added and removed as needed depending on the current field value.

Defaults to: 'x-form-empty-field'. Overridden to undefined as emptyText is not supported with inputType :'file' and should be avoided. The default text to place into an empty field. The label for the field. It gets appended with the labelSeparator , and its position and sizing is determined by the labelAlign and labelWidth configs. Returns the label for the field. Defaults to simply returning the fieldLabel config. Can be overridden to provide a custom generated label.

This is a template method. Feel free to override it in child classes. The new label. The labelSeparator will be automatically appended to the label string. Optional CSS style s to be applied to the field input element. Should be a valid argument to Ext. Element applyStyles. Defaults to undefined. See also the setFieldStyle method for changing the style after initialization.

Set the CSS style of the field input element. The style s to apply. Configure as true to have this Component fixed at its X, Y coordinates in the browser viewport, immune to scrolling the document. Flex may be applied to child items of a box layout Ext. VBox or Ext. Each child item with a flex property will fill space horizontally in hbox , vertically in vbox according to that item's relative flex value compared to the sum of all items with a flex value specified.

Any child items that have either a flex of 0 or undefined will not be 'flexed' the initial size will not be changed. Sets the flex property of this component. Only applicable when this component is an item of a box layout. Specify as true to float the Component outside of the document flow using CSS absolute positioning. Components such as Ext. Window s and Ext. You don't get to handle the response since it is a standard submit. I thought the same the first time I faced it, look: stackoverflow.

Is there a way to implement a "processing file" mask? Forget about the ajax, and just get plain old js to open the file for you: window. Kyle Fransham Kyle Fransham 1, 16 16 silver badges 22 22 bronze badges. John John 61 1 1 bronze badge. Yes, that works fine. If you are using Sencha Cmd to build you will need to require 'Ext. StandardSubmit' also. Thanks and to all above also. Sudhakar Sudhakar 2, 1 1 gold badge 25 25 silver badges 30 30 bronze badges. I just had to ad to the success function of the ajax request: window.

I still think that the ajax is unnecessary. You can do this call outside of the success block. You are still opening a window with a url I would have the browser prompting the download window by changing the response type With the standard submit approach — code4jhon. Set things up so we check the status again in milliseconds window. Sergey Bogdanov 10 10 silver badges 19 19 bronze badges.

The scope this reference in which the handler function is executed. If omitted, defaults to the object which fired the event. Note: The options object will also be passed as the last argument to every event handler.

Causes the handler to be scheduled to run in an Ext. 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. Causes the handler to be scheduled to run at the next animation frame event.

If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed. Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

This option is only valid for listeners bound to Ext. The name of a Component property which references an Ext. Element to add a listener to. Component which will exist only after the Component is rendered. In order to remove listeners attached using the element, you'll need to reference the element itself as seen below. The "delegate" option is only available on Ext. Element instances or when attaching a listener to a Ext. Element via a Component using the element option.

When set to true , the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase. The capture option is only available on Ext. Optional arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these arguments. When specified as true , the function returns a destroyable object.

An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un ; particularly when removing multiple listeners.

NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config. An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority.

Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of or greater, and or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of to when setting the priority of event handlers in application-level code.

A priority must be an integer to be valid. Fractional values are reserved for internal framework use. A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:.

A shortcut for the order event option. Provided for backward compatibility. Please use the priority event option instead.

A Destroyable object. The addManagedListener method is used when some object call it "A" is listening to an event on another observable object "B" and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time. As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu MyApp. SomeGlobalSharedMenu is also removed. As of version 5.

However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

If the ename parameter was an event name, this is the handler function or the name of a method on the specified scope. If the ename parameter was an event name, this is the scope this reference in which the handler function is executed.

If the ename parameter was an event name, this is the addListener options. Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override see Ext define. To override a method and replace it and also call the superclass method, use method-callSuper. This is often done to patch a method to fix a bug. The arguments, either an array or the arguments object from the current method, for example: this.

This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly. To patch the bug in Ext. The patch method cannot use method-callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

Creates an event handling function which re-fires the event from this object as the passed event name. This method is called to cleanup an object and its resources. After calling this method, the object should not be used any further. Enables events fired by this Observable to bubble up an owner hierarchy by calling this. There is no implementation in the Observable base class.

This is commonly used by Ext. Components to bubble events to owner Containers. 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.

Fires the specified event with the passed parameters and executes a function action. By default, the action function will be executed after any "before" event handlers as specified using the order option of addListener , but before any other handlers are fired.

This gives the "before" handlers an opportunity to cancel the event by returning false , and prevent the action function from being called. The action can also be configured to run after normal handlers, but before any "after" handlers as specified using the order event option by passing 'after' as the order parameter.

This configuration gives any event handlers except for "after" handlers the opportunity to cancel the event and prevent the action function from being called. Event options for the action function. Accepts any of the options of addListener. The order to call the action function relative too the event handlers 'before' or 'after'.

But in some cases the web application may want to handle the download part itself, rather than leaving it to the browser. It may have its own reasons like showing the download progress of the file in the applicaton's UI itself. Another reason may be monetization - the application can show an advertisement to the user while the file is being downloaded. This tutorial shows how to make an AJAX request to download a file, and showing the download percentage completed.
