protected long createContextARBImpl(final long share, final boolean direct, final int ctp, final int major, final int minor)

Implements abstract jogamp.opengl.GLContextImpl.createContextARBImpl.

Doc from jogamp.opengl.GLContextImpl.createContextARBImpl.

Platform dependent but harmonized implementation of the ARB_create_context mechanism to create a context.
This method is called from createContextARB, createImpl(long) .. makeCurrent() .
The implementation shall verify this context with a MakeContextCurrent call.
The implementation must leave the context current.

Parameters
share:long

the shared context or null

direct:boolean

flag if direct is requested

ctp:int

ARB_create_context related, see references below

major:int

major number

minor:int

minor number

Returns:long

the valid and current context if successful, or null

protected boolean createImpl(final long shareWithHandle) throws GLException

Implements abstract jogamp.opengl.GLContextImpl.createImpl.

Doc from jogamp.opengl.GLContextImpl.createImpl.

Platform dependent entry point for context creation.

This method is called from makeCurrentWithinLock() .. makeCurrent() .

The implementation shall verify this context with a MakeContextCurrent call.

The implementation must leave the context current.

Non fatal context creation failure via return false is currently implemented for: MacOSXCGLContext.

Parameters
shareWithHandle:long

the shared context handle or 0

Returns:boolean

true if successful. Method returns false if the context creation failed non fatally, hence it may be created at a later time. Otherwise method throws GLException.
