Using Qt4 Embedded widgets in Qt3

[kobleh]

We are planning on using Qt on a low powered processor. Unfortunately Qt4 grinds on this system but Qt3 works fine. The problem is that we want to use some of the Qt4 Embedded widgets (http://www.qtsoftware.com/developer/embedded-widget-demos) on this system since they look so much better than what is available on Qt3.

Has anyone successfully back-ported the Qt4 Embedded widgets to Qt3 or does anyone have any thoughts on performing this type of operation?

Thanks in advance for any advice provided.

You won't be able to port those widgets to Qt3 because they use SVG images for their looks and there is no way to simulate it on Qt3. If you get rid of SVG when trying to port to Qt3, you will lose quality. If you don't care about scaling then that is an option though.

Scaling would not be required since we will be dealing with fixed HMI screens. We are really only interested in the nice looking Gauges, Multi-Slider, and ScrollWheel.

Do you foresee any other road blocks and/or have any idea on the amount of work involved?

Thanks for your response.

Then just take the SVG files, convert them to PNG and you're done.
