Method Detail

create

protected static WindowsExternalWGLContext create(GLDrawableFactory factory,
                                                  GLProfile glp)

makeCurrent

public int makeCurrent()
                throws GLException
Description copied from class: GLContextImpl
MakeCurrent functionality, which also issues the creation of the actual OpenGL context.
The complete callgraph for general OpenGL context creation is:

Once at startup, ie triggered by the singleton constructor of a GLDrawableFactoryImpl specialization, calling GLContextImpl.createContextARB(long, boolean, int[], int[], int[]) will query all available OpenGL versions:

Overrides:
makeCurrent in class GLContextImpl
Returns:
CONTEXT_CURRENT if the context was successfully made current
Throws:
GLException - if synchronization is disabled and the context is current on another thread, or because the context could not be created or made current due to non-recoverable, window system-specific errors.
See Also:
GLContextImpl.makeCurrentImpl(boolean), #create, GLContextImpl.createContextARB(long, boolean, int[], int[], int[]), GLContextImpl.createContextARBImpl(long, boolean, int, int, int), #mapVersionAvailable, GLContextImpl.destroyContextARBImpl(long)

release

public void release()
             throws GLException
Description copied from class: GLContext
Releases control of this GLContext from the current thread.

Overrides:
release in class GLContextImpl
Throws:
GLException - if the context had not previously been made current on the current thread

makeCurrentImpl

protected void makeCurrentImpl(boolean newCreated)
                        throws GLException
Overrides:
makeCurrentImpl in class WindowsWGLContext
Throws:
GLException

releaseImpl

protected void releaseImpl()
                    throws GLException
Overrides:
releaseImpl in class WindowsWGLContext
Throws:
GLException

destroyImpl

protected void destroyImpl()
                    throws GLException
Overrides:
destroyImpl in class WindowsWGLContext
Throws:
GLException
