How can I make a banner in QT, like the news banner of CNN/FOX?

Question

Hi, as the title says, I want to add my main window a banner in the bottom of the window that shows text that runs from left to right, just like you can see in your TV when watching fox/CNN...

I'm using QT 4.5.2

Thanks a lot :)

You have many options. You could:

• Create a custom widget and override QWidget::paintEvent()
• Drawing your text to an image and then repainting that image as often as needed
• Creating a QGraphicsScene and then moving an appropriate text item around.

QTimeline and/or QTimer will likely be useful in your implementation. The key idea is that you need to draw something at different positions at consistent intervals. If you redraw frequently enough, it will look like an animation.
