    Note : This is an advanced setting

    Parameters:
      `ariaLabel` - New ariaLabel value. Default value is null
    Returns:
      `StatefulCanvas` instance, for chaining setter calls

  - ### getAriaLabel

    public String getAriaLabel()

  - ### setAutoFit

    public StatefulCanvas setAutoFit(Boolean autoFit)
    If true, ignore the specified size of this widget and always size just large enough to accommodate the title. If `setWidth()` is explicitly called on an autoFit:true button, autoFit will be reset to `false`.

    Note that for StretchImgButton instances, autoFit will occur horizontally only, as unpredictable vertical sizing is likely to distort the media. If you do want vertical auto-fit, this can be achieved by simply setting a small height, and having overflow:"visible"
    If this method is called after the component has been drawn/initialized: Setter method for the `autoFit` property. Pass in true or false to turn autoFit on or off. When autoFit is set to `false`, canvas will be resized to it's previously specified size.

    Parameters:
      `autoFit` - New autoFit setting. Default value is null
    Returns:
      `StatefulCanvas` instance, for chaining setter calls
    See Also:
      - `Sizing overview and related methods`

  - ### getAutoFit

    public Boolean getAutoFit()
    If true, ignore the specified size of this widget and always size just large enough to accommodate the title. If `setWidth()` is explicitly called on an autoFit:true button, autoFit will be reset to `false`.

    Note that for StretchImgButton instances, autoFit will occur horizontally only, as unpredictable vertical sizing is likely to distort the media. If you do want vertical auto-fit, this can be achieved by simply setting a small height, and having overflow:"visible"

    Returns:
      Current autoFit value. Default value is null
    See Also:
      - `Sizing overview and related methods`

  - ### setBaseStyle

    public StatefulCanvas setBaseStyle(String baseStyle)
    Base CSS style className applied to the component.

    Note that if specified, this property takes precedence over any specified `styleName`. If unset, the `styleName` will be used as a default `baseStyle` value.

    As the component changes `state` and/or is selected, suffixes will be added to the base style. In some cases more than one suffix will be appended to reflect a combined state ("Selected" + "Disabled", for example).

    See `getStateSuffix()` for a description of the default set of suffixes which may be applied to the baseStyle

    #### Rotated Titles

    The Framework doesn't have built-in support for rotating button titles in a fashion similar to `FacetChart.rotateLabels`. However, you can manually configure a button to render with a rotated title by applying custom CSS via this property.

    For example, given a button with a height of 120 and a width of 48, if you copied the existing buttonXXX style declarations from skin_styles.css as new, rotatedTitleButtonXXX declarations, and then added the lines:

              -ms-transform:     translate(-38px,0px) rotate(270deg);
              -webkit-transform: translate(-38px,0px) rotate(270deg);
              transform:         translate(-38px,0px) rotate(270deg);
              overflow: hidden;
              text-overflow: ellipsis;
              width:116px;

    in the declaration section beginning:

          .rotatedTitleButton,
          .rotatedTitleButtonSelected,
          .rotatedTitleButtonSelectedOver,
          .rotatedTitleButtonSelectedDown,
          .rotatedTitleButtonSelectedDisabled,
          .rotatedTitleButtonOver,
          .rotatedTitleButtonDown,
          .rotatedTitleButtonDisabled {

    then applying that style to the button with `overflow`: "clip_h" would yield a vertically-rendered title with overflow via ellipsis as expected, and also wrap with `Button.wrap`. Note that:
    - The explicit width applied via CSS is needed because rotated elements don't inherit dimensions in their new orientation from the DOM - the transform/rotation occurs independently of layout.
    - The translation transform required along the x-axis is roughly (width - height) / 2, but may need slight offsetting for optimal centering.
    - We've explicitly avoided describing an approach based on CSS "writing-mode", since support is incomplete and bugs are present in popular browsers such as Firefox and Safari that would prevent it from being used without Framework assistance.

    Note on css-margins: Developers should be aware that the css "margin" property is unreliable for certain subclasses of StatefulCanvas, including `buttons`. Developers may use the explicit `Canvas.margin` property to specify button margins, or for a button within a layout, consider the layout properties `Layout.layoutMargin`, `Layout.membersMargin`
    If this method is called after the component has been drawn/initialized: Sets the base CSS style. As the component changes state and/or is selected, suffixes will be added to the base style.

    Parameters:
      `baseStyle` - new base style. Default value is null
    Returns:
      `StatefulCanvas` instance, for chaining setter calls
    See Also:
      - `CSSStyleName`

  - ### getBaseStyle

    public String getBaseStyle()
    Base CSS style className applied to the component.

    Note that if specified, this property takes precedence over any specified `styleName`. If unset, the `styleName` will be used as a default `baseStyle` value.

    As the component changes `state` and/or is selected, suffixes will be added to the base style. In some cases more than one suffix will be appended to reflect a combined state ("Selected" + "Disabled", for example).

              transform:         translate(-38px,0px) rotate(270deg);
              overflow: hidden;
              text-overflow: ellipsis;
              width:116px;

    in the declaration section beginning:

          .rotatedTitleButton,
          .rotatedTitleButtonSelected,
          .rotatedTitleButtonSelectedOver,
          .rotatedTitleButtonSelectedDown,

          .rotatedTitleButtonOver,
          .rotatedTitleButtonDown,

    Note that the string "blank" is a valid setting for this attribute and will always result in the system blank image, with no state suffixes applied. Typically, this might be used when an iconStyle is also specified and the iconStyle renders the icon via a stateful background-image or other CSS approach.
    If this method is called after the component has been drawn/initialized: Change the icon being shown next to the title text.

    Parameters:
      `icon` - URL of new icon. Default value is null

    See Also:
      - `Button Icon`

  - ### setIconSize

    public StatefulCanvas setIconSize(int iconSize) throws IllegalStateException
    Size in pixels of the icon image.

    The `iconWidth` and `iconHeight` properties can be used to configure width and height separately.

    Note: When configuring the properties of a `StatefulCanvas` (or derivative) `AutoChild`, it is best to set the `iconWidth` and `iconHeight` to the same value rather than setting an `iconSize`. This is because certain skins or customizations thereto might set the `iconWidth` and `iconHeight`, making the customization of the AutoChild's `iconSize` ineffective.

      `iconSize` - New iconSize value. Default value is 16
    Returns:
      `StatefulCanvas` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created

      - `Button Icon`

  - ### getIconSize

    public int getIconSize()
    Size in pixels of the icon image.

    The `iconWidth` and `iconHeight` properties can be used to configure width and height separately.

    Note: When configuring the properties of a `StatefulCanvas` (or derivative) `AutoChild`, it is best to set the `iconWidth` and `iconHeight` to the same value rather than setting an `iconSize`.

    Returns:
      Current iconSize value. Default value is 16
    See Also:
      - `Button Icon`

  - ### setIconStyle

    public StatefulCanvas setIconStyle(String iconStyle)
    Base CSS style applied to the icon image. If set, as the `StatefulCanvas` changes `state` and/or is `selected`, suffixes will be appended to `iconStyle` to form the className set on the image element.

  - ### setDefaultProperties

    public static void setDefaultProperties(StatefulCanvas statefulCanvasProperties)
    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 set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. 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:
      `statefulCanvasProperties` - properties that should be used as new defaults when instances of this class are created
