    - #### setAutoFit

          public void setAutoFit(java.lang.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`.

        `autoFit` - New autoFit setting.. Default value is null

    - #### setState

          public void setState(State state)

      Current "state" of this widget. The state setting is automatically updated as the user interacts with the component (see `showRollOver`, `showDown`, `showDisabled`).

      StatefulCanvases will have a different appearance based on their current state. By default this is handled by changing the css className applied to the StatefulCanvas - see `baseStyle` and `getStateSuffix()` for a description of how this is done.

      For `Img` or `StretchImg` based subclasses of StatefulCanvas, the appearance may also be updated by changing the src of the rendered image. See `Img.src` and `StretchImgButton.src` for a description of how the URL is modified to reflect the state of the widget in this case.
      If this method is called after the component has been drawn/initialized: Sets the `state` of this object, changing its appearance. Note: `newState` cannot be `State.STATE_DISABLED` if `this.showDisabled` is `false`.

      Note : This is an advanced setting

      Parameters:
        `state` - the new state.. Default value is ""

        `State`, `State overview and related methods`

    - #### getState

          public State getState()

    - #### removeFromRadioGroup

          public void removeFromRadioGroup(java.lang.String groupID)

      Remove this widget from the specified mutually exclusive selection group with the ID passed in. No-op's if this widget is not a member of the groupID passed in. If no groupID is passed in, defaults to removing from whatever radioGroup this widget is a member of.

    - #### 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
      See Also:
        `SGWTProperties`
