how to display batter power meter

[qtnewbie]

I need to display a battery power meter using QT 4.3. Using the QProgressBar or QPainter to draw a rectangle and fill it according to the current battery level are the two solutions I've thought of.

Are there simpler ways to display a battery power meter image?

You can subclass QWidget and override paintEvent. In there you can do custom painting like gradients, images and other more complex drawing to make your meter look good.

You would set up a max point to a progressbar, I don't know, let's say 100 for 100% and then supply the current battery value with QProgressBar::value().
