List of makeCurrent() Examples

Examples of makeCurrent()

javax.media.opengl.GLContext.makeCurrent()
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. @return CONTEXT_CURRENT if the context was successfully made current @return CONTEXT_CURRENT_NEW if the context was successfully madecurrent, but need to be initialized. @return CONTEXT_NOT_CURRENT if the context could not be made current. @throws GLException if synchronization is disabled and thecontext is current on another thread, or because the context could not be created or made current due to non-recoverable, window system-specific errors.
