OK, so here's where we're at now... I spent a good bit of time trying alternative approaches and even trying to hard wire the size of m_[segments|artifacts]DrawBuffer to anything at all except 96 x 26. I experienced 100% failure. I figured if QPixmap::resize_helper() could do the job we expect done, then why not subclass and implement Rosegarden::Pixmap to lift that code straight out of Qt. QPixmap::resize_helper() is what all the other calls resolve to. It seemed like a fine idea to me, but that method makes deep use of internal Qt implementation bits and bobs that are inaccessible without an absurd amount of hacking. The further I went down that path, the more I started to notice the trees looked like they were thinking about eating me. I wisely stepped back, and I'm done. If Rosegarden is going to survive past the end of Qt 3 support, then somebody needs to figure out how to rewrite CompositionView::resizeEvent() so it doesn't rely on QPixmap::resize(). How to do that, I ha'n't a clue. -- D.
