Methods

Modifier and Type	Method and 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.
