```
public interface ControlWrapper
```
Wraps an SWT Control to encapsulate its API.
The traditional way to make a custom class is this: class CustomControl extends Composite
This has three main problems:
1. Users can add random widgets to your "Control" because it exposes the Composite interface.
2. Users can set the layout to your "Control" because it exposes the Composite interface.
3. Users can add random listeners to your "Control", and overridding Widget.addListener to intercept them is a very dangerous plan.
ControlWrapper fixes this by providing an low-overhead skeleton which encapsulates the SWT Control that you're using as the base of your custom control, which allows you to only expose the APIs that are appropriate.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default void`	`dispose()`	Disposes the underlying control.
`default Object`	`getLayoutData()`	Returns the LayoutData for this control.
`default Composite`	`getParent()`	Returns the parent of this Control.
`Control`	`getRootControl()`	Returns the wrapped `Control` (only appropriate for limited purposes!).
`default Shell`	`getShell()`	Returns the parent Shell of this Control.
`default boolean`	`isDisposed()`	Returns true iff the underlying control is disposed.
`default void`	`setLayoutData(Object layoutData)`	Sets the LayoutData for this control.
`default boolean`	`setParent(Composite parent)`	Changes the parent of the widget to be the one provided.
`static <T extends Control> ControlWrapper.Transparent<T>`	`transparent(T control)`	Most-efficient way to transparently pass a Control to a ControlWrapper API.

- Method Detail
  - setLayoutData
```
default void setLayoutData(Object layoutData)
```
    Sets the LayoutData for this control.
  - getLayoutData
```
default Object getLayoutData()
```
    Returns the LayoutData for this control.
  - getParent
```
default Composite getParent()
```
    Returns the parent of this Control.
  - getShell
```
default Shell getShell()
```
    Returns the parent Shell of this Control.
  - dispose
```
default void dispose()
```
    Disposes the underlying control.
  - isDisposed
```
default boolean isDisposed()
```
    Returns true iff the underlying control is disposed.
  - setParent
```
default boolean setParent(Composite parent)
```
    Changes the parent of the widget to be the one provided. Returns true if the parent is successfully changed
  - getRootControl
```
Control getRootControl()
```
    Returns the wrapped Control (only appropriate for limited purposes!).
    The implementor of this ControlWrapper is free to change the wrapped Control as she sees fit, and she doesn't have to tell you about it! You shouldn't rely on this control being anything in particular.
    You can rely on this Control for:
    
    Managing lifetimes: `wrapped.getRootControl().addListener(SWT.Dispose, ...`
    
    But that's all. If you use it for something else, it's on you when it breaks.
  - transparent
```
static <T extends Control> ControlWrapper.Transparent<T> transparent(T control)
```
    Most-efficient way to transparently pass a Control to a ControlWrapper API.
