[Qt-interest] Progressive/incremental image loading

Hello there,

I just wanted to ask whether anyone knows if there are plans for Qt to support 
progressive/incremental image loading in the near future (I'm referring to the 
ability of an image reader to notify interested objects about the progress 
made, so that they can display what has already been loaded).

Java's ImageIO classes shipped with the runtime enivronment provide a very 
neat interface based on a number of different events with information about 
the current load progress or the area of the image that has just been 
populated (if you are interested, have a look at the following: 
A feature like this would certainly be nice for quite a few use cases, 
especially when one wants to provide the user with something to watch while 
reading images asynchronously.

So, are there any plans on incorporating such a feature into Qt?

Best regards,
Ingomar Wesp
