SharedDrawable (LWJGL API)

java.lang.Object
- org.lwjgl.opengl.SharedDrawable

All Implemented Interfaces:

Drawable
```
public final class SharedDrawable
extends Object
```
A Drawable implementation that shares its context with another Drawable. This is useful for background loading of resources. See org.lwjgl.test.opengl.multithread.BackgroundLoad for an example.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected void`	`checkDestroyed()`

`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.
