Bool_t ReleaseLock(TGLLockable::ELock lock) const
 Release current lock, make sure it the same as the 'lock' argument.
 Returns TRUE on success, FALSE on failure.
const char* LockName(TGLLockable::ELock lock)
 Return name-string for given lock-type.
Bool_t LockValid(TGLLockable::ELock lock)
 Test if lock is a valid type to take/release.
 kUnlocked is never valid in these cases.
TGLLockable(const TGLLockable& )
TGLLockable& operator=(const TGLLockable& )
virtual ~TGLLockable()
const char* LockIdStr()
{ return "<unknown>"; }
Bool_t IsLocked()
{ return (fLock != kUnlocked); }
ELock CurrentLock()
{ return fLock; }
Bool_t IsDrawOrSelectLock()
{ return fLock == kDrawLock || fLock == kSelectLock; }
