QAbstractTableModel for continuous pixel stream

[anda_skoa]

But why doesn't Qt suppor something like a "QImageView"!!

There are many classes that can be a "QImageView", e.g. QLabel, QPixmapItem in a QGraphicsView, any custom widget using QPainter, etc.

I mean I wanted to use Qt's Model-View architecture for displaying pixel data from the data model to the GUI.

Why, which of the model/view features do you need?

The processing in the GUI takes about 5-7 milliseconds depending on the size of the image since each pixel value is mapped to RGB:

Just some ideas:
- you seem to allocate a new image every time
- you are using two nested loops instead of scanline() or bits() for direct data access
- if you use the same value for red/green/blue, isn't that a grayscale image? In which case an image with a color table might be faster

Cheers,
