I'm writing an application that, among other things, needs to display a scrolling text ticker.
QPropertyAnimation looked like it would do the trick. Unfortunately, as soon as the app starts
doing those other things (displaying image slide shows, videos, web pages, flash), the animation
stutters.
Since only the main thread can access the GUI in Qt, I believe I can't move the ticker to
another thread. Moving loading and scaling of the images for the slide show to another thread
helped, but not for videos (Phonon::VideoWidget) or other content (QWebView).
Am I missing something obvious, or is it really such a big deal to put smooth scrolling text on
the screen?
