    Constructor

    constructor

    constructor(element: any, tile: Tile): Toolbar
    

    Initializes a new instance of the Toolbar class and attaches it to a DOM element.

    Parameters
    • element: any

      The DOM element that hosts the control, or a CSS selector for the host element (e.g. '#theCtrl').

    • tile: Tile

      The tile which owns the toolbar.

    Returns
    Toolbar

    Properties

    hostElement

    Gets the DOM element that is hosting the control.

    isDisabled

    Gets or sets a value that determines whether the control is disabled.

    Disabled controls cannot get mouse or keyboard events.

    Control
    Type
    boolean

    tabOrder

    Gets or sets a value of the **tabindex** attribute associated with the control.

    **tabindex** attribute value can be defined statically for a Wijmo control by specifying it on the control's host HTML element. But this value can't be changed later during application lifecycle, because Wijmo controls have complex structure, and the control may need to propagate this attribute value to its internal element to work properly.

    Because of this, to read or change control's **tabindex** dynamically, you should do it using this property.

    Methods

    addEventListener

    addEventListener(target: EventTarget, type: string, fn: any, capture?: boolean, passive?: boolean): void
    

    Adds an event listener to an element owned by this Control.

    The control keeps a list of attached listeners and their handlers, making it easier to remove them when the control is disposed (see the dispose and removeEventListener methods).

    Failing to remove event listeners may cause memory leaks.

    The passive parameter is set to false by default, which means the event handler may call event.preventDefault(). If you are adding passive handlers to touch or wheel events, setting this parameter to true will improve application performance.

    For details on passive event listeners, please see Improving scrolling performance with passive listeners.

    Parameters
    • target: EventTarget

      Target element for the event.

    • type: string

      String that specifies the event.

    • fn: any

      Function to execute when the event occurs.

    • capture: boolean
    Optional

    Whether the listener should be handled by the control before it is handled by the target element.

    Indicates that the handler will never call preventDefault().

    Inherited From
    Control
    Returns
    void

    applyTemplate

    applyTemplate(classNames: string, template: string, parts: Object, namePart?: string): HTMLElement
    

    Applies the template to a new instance of a control, and returns the root element.

    This method should be called by constructors of templated controls. It is responsible for binding the template parts to the corresponding control members.

    For example, the code below applies a template to an instance of an InputNumber control. The template must contain elements with the 'wj-part' attribute set to 'input', 'btn-inc', and 'btn-dec'. The control members '_tbx', '_btnUp', and '_btnDn' will be assigned references to these elements.

    ```typescript this.applyTemplate('wj-control wj-inputnumber', templateString, { _tbx: 'input', _btnUp: 'btn-inc', _btnDn: 'btn-dec' }, 'input'); ``````

    Parameters
    • classNames: string

      Names of classes to add to the control's host element.

    • template: string

      An HTML string that defines the control template.

    • parts: Object

      A dictionary of part variables and their names.

    • namePart: string
    Optional

    Name of the part to be named after the host element. This determines how the control submits data when used in forms.

    beginUpdate

    beginUpdate(): void
    

    Suspends notifications until the next call to endUpdate.

    Inherited From
    Control
    Returns
    void

    clear

    clear(): void
    

    Clears all the toolbar items.

    Returns
    void

    containsFocus

    containsFocus(): boolean
    

    Checks whether this control contains the focused element.

    Inherited From
    Control
    Returns
    boolean

    deferUpdate

    deferUpdate(fn: Function): void
    

    Executes a function within a beginUpdate/endUpdate block.

    The control will not be updated until the function has been executed. This method ensures endUpdate is called even if the function throws an exception.

    Parameters
    Inherited From
    Control
    Returns
    void

    dispose

    dispose(): void
    

    Disposes of the control by removing its association with the host element.

    The dispose method automatically removes any event listeners added with the addEventListener method.

    Calling the dispose method is important in applications that create and remove controls dynamically. Failing to dispose of the controls may cause memory leaks.

    Inherited From
    Control
    Returns
    void

    Static disposeAll

    disposeAll(e?: HTMLElement): void
    

    Disposes of all Wijmo controls contained in an HTML element.

    Parameters
    Inherited From
    Control
    Returns
    void

    endUpdate

    endUpdate(): void
    

    Resumes notifications suspended by calls to beginUpdate.

    Inherited From
    Control
    Returns
    void

    focus

    focus(): void
    

    Sets the focus to this control.

    Inherited From
    Control
    Returns
    void

    Static getControl

    getControl(element: any): Control
    

    Gets the control that is hosted in a given DOM element.

    Parameters
    • element: any

      The DOM element that hosts the control, or a CSS selector for the host element (e.g. '#theCtrl').

    Inherited From
    Control
    Returns
    Control

    getTemplate

    getTemplate(): string
    

    Gets the HTML template used to create instances of the control.

    This method traverses up the class hierarchy to find the nearest ancestor that specifies a control template. For example, if you specify a prototype for the ComboBox control, which does not specify a template, it will override the template defined by the DropDown base class (the nearest ancestor that does specify a template).

    Inherited From
    Control
    Returns
    string

    initialize

    initialize(options: any): void
    

    Initializes the control by copying the properties from a given object.

    This method allows you to initialize controls using plain data objects instead of setting the value of each property in code.

    For example:

    ```typescript grid.initialize({ itemsSource: myList, autoGenerateColumns: false, columns: [ { binding: 'id', header: 'Code', width: 130 }, { binding: 'name', header: 'Name', width: 60 } ] });

    // is equivalent to grid.itemsSource = myList; grid.autoGenerateColumns = false; // etc. ```

    The initialization data is type-checked as it is applied. If the initialization object contains unknown property names or invalid data types, this method will throw.

    Parameters
    • options: any

      Object that contains the initialization data.

    Inherited From
    Control
    Returns
    void

    insertSVGButton

    • index: number Optional

      The position where the item is inserted.

    Returns
    void

    insertToolbarItem

    insertToolbarItem(item: IToolbarItem, index?: number): void
    

    Insert a toolbar item into the specified position.

    Parameters
    • item: IToolbarItem

      The toolbar item which is inserted.

    • index: number Optional

      The position where the item is inserted.

    Returns
    void

    invalidate

    invalidate(fullUpdate?: boolean): void
    

    Invalidates the control causing an asynchronous refresh.

    Parameters
    • fullUpdate: boolean Optional

      Whether to update the control layout as well as the content.

    Inherited From
    Control
    Returns
    void

    Static invalidateAll

    invalidateAll(e?: HTMLElement): void
    

    Invalidates all Wijmo controls contained in an HTML element.

    Use this method when your application has dynamic panels that change the control's visibility or dimensions. For example, splitters, accordions, and tab controls usually change the visibility of its content elements. In this case, failing to notify the controls contained in the element may cause them to stop working properly.

    If this happens, you must handle the appropriate event in the dynamic container and call the invalidateAll method so the contained Wijmo controls will update their layout information properly.

    Parameters
    • e: HTMLElement Optional

      Container element. If set to null, all Wijmo controls on the page will be invalidated.

    Inherited From
    Control
    Returns
    void

    onGotFocus

    onGotFocus(e?: EventArgs): void
    

    Raises the gotFocus event.

    Parameters
    Inherited From
    Control
    Returns
    void

    onInvalidInput

    onInvalidInput(e: CancelEventArgs): void
    

    Raises the invalidInput event.

    If the event handler cancels the event, the control will keep the invalid input and the focus.

    Parameters
    Inherited From
    Control
    Returns
    void

    onLostFocus

    onLostFocus(e?: EventArgs): void
    

    Raises the lostFocus event.

    Control
    Arguments
    EventArgs

    invalidInput

    Occurs when invalid input is detected.

    Invalid input may occur when the user types or pastes a value that cannot be converted to the proper type, or a value that is outside the valid range.

    If the event handler cancels the event, the control will retain the invalid content and the focus, so users can correct the error.

    If the event is not canceled, the control will ignore the invalid input and will retain the original content.
