* OPT: Using object references is faster. * BUG: Fix a misuse of GB.NewString() in the String class. [COMPILER] * BUG: Raise an error now when trying to create an array of structures. [GB.QT4] * OPT: Global widget event filter is faster. * OPT: Do not internallt relayout TabStrip too often, because Qt takes a lot of time to do that. git-svn-id: svn://localhost/gambas/trunk@2974 867c0c6c-44f3-4631-809d-bfa615b0a4ec
