  - ### setDefaultProperties

    public static void setDefaultProperties(ButtonItem buttonItemProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `buttonItemProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`

  - ### getCanvas

    public Canvas getCanvas()
    Description copied from class: `CanvasItem`
    The canvas that will be displayed inside this item. You can pass an instance you've already created, or its global ID as a String.

    If a `canvas` hasn't been specified via `setCanvas()`, the canvas for this item will be auto-created as configured by the methods `setAutoChildProperties()` and `setAutoChildConstructor()`.

    Note that subclasses of `CanvasItem` may use a different AutoChild name than just "canvas". For example, `SliderItem` uses "slider", and in that case, you need to use the specific APIs provided by the subclass.

    Note that `Canvas.canvasItem` will be set on the canvas to point back to this item.

    This component is an AutoChild named "canvas". For an overview of how to use and configure AutoChildren, see `Using AutoChildren`.

    Overrides:
      `getCanvas` in class `CanvasItem`
    Returns:
      Current canvas value. Default value is null

  - ### setButtonProperties

    public void setButtonProperties(Button buttonProperties)
    Custom Properties to apply to the button item.
    Parameters:
      `buttonProperties` - properties to apply to the button item.
