Method Detail

create

protected void create()

Description copied from class: X11GLContext

Helper routine which usually just turns around and calls createContext (except for pbuffers, which use a different context creation mechanism). Should only be called by X11GLContext.makeCurrentImpl().

Specified by:

create in class X11GLContext

makeCurrent

public int makeCurrent()
                throws GLException

Description copied from class: GLContext

Makes this GLContext current on the calling thread. There are two return values that indicate success and one that indicates failure. A return value of CONTEXT_CURRENT_NEW indicates that that context has been made current, and that this is the first time this context has been made current, or that the state of the underlying context or drawable may have changed since the last time this context was made current. In this case, the application may wish to initialize the state. A return value of CONTEXT_CURRENT indicates that the context has been made currrent, with its previous state restored. If the context could not be made current (for example, because the underlying drawable has not ben realized on the display) , a value of CONTEXT_NOT_CURRENT is returned. If the context is in use by another thread at the time of the call, then if isSynchronized() is true the call will block. If isSynchronized() is false, an exception will be thrown and the context will remain current on the other thread.

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.

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 int makeCurrentImpl()
                       throws GLException

Overrides:

makeCurrentImpl in class X11GLContext

Throws:

GLException

releaseImpl

protected void releaseImpl()
                    throws GLException

Overrides:

releaseImpl in class X11GLContext

Throws:

GLException

destroyImpl

protected void destroyImpl()
                    throws GLException

Overrides:

destroyImpl in class X11GLContext

Throws:

GLException

isCreated

public boolean isCreated()

Description copied from class: GLContextImpl

Indicates whether the underlying OpenGL context has been created. This is used to manage sharing of display lists and textures between contexts.

Overrides:

isCreated in class X11GLContext
