    public interface HasVisibility

Implemented by objects that have the visibility trait.

Method Summary
`boolean` | `isVisible()` Determines whether or not this object is visible.
`void` | `setVisible(boolean visible)` Sets whether this object is visible.

Method Detail

### isVisible

    boolean isVisible()

  Determines whether or not this object is visible. Note that this does not necessarily take into account whether or not the receiver's parent is visible, or even if it is attached to the `Document`. The default implementation of this trait in `UIObject` is based on the value of a dom element's style object's display attribute.

  Returns:
    `true` if the object is visible

### setVisible

    void setVisible(boolean visible)

  Sets whether this object is visible.

  Parameters:
    `visible` - `true` to show the object, `false` to hide it
