Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`destroy()`	Destroys the Drawable.
`boolean`	`isCurrent()`	Returns true if the Drawable's context is current in the current thread.
`void`	`makeCurrent()`	Makes the Drawable's context current in the current thread.
`void`	`releaseContext()`	If the Drawable's context is current in the current thread, no context will be current after a call to this method.
`void`	`setCLSharingProperties(PointerBuffer properties)`	Sets the appropriate khr_gl_sharing properties in the target `PointerBuffer`, so that if it is used in a `clCreateContext(FromType)` call, the created CL context will be sharing objects with this `Drawable`'s GL context.

- Method Detail
  - isCurrent
```
boolean isCurrent()
           throws LWJGLException
```
    Returns true if the Drawable's context is current in the current thread.
    
    Throws:
    
    LWJGLException
  - makeCurrent
```
void makeCurrent()
          throws LWJGLException
```
    Makes the Drawable's context current in the current thread.
    
    Throws:
    
    LWJGLException
  - releaseContext
```
void releaseContext()
             throws LWJGLException
```
    If the Drawable's context is current in the current thread, no context will be current after a call to this method.
    
    Throws:
    
    LWJGLException
  - destroy
```
void destroy()
```
    Destroys the Drawable.
  - setCLSharingProperties
```
void setCLSharingProperties(PointerBuffer properties)
                     throws LWJGLException
```
    Sets the appropriate khr_gl_sharing properties in the target PointerBuffer, so that if it is used in a clCreateContext(FromType) call, the created CL context will be sharing objects with this Drawable's GL context. After a call to this method, the target buffer position will have advanced by 2 to 4 positions, depending on the implementation.
    
    Parameters:
    
    properties - The target properties buffer. It must have at least 4 positions remaining.
    
    Throws:
    
    LWJGLException
