Using TWAIN/SANE/CUPS with Qt.

Max13

Hi,

I'm Qt Ambassador, and as one of them, I talk about Qt everytime I can and to everyone interested in my T-Shirt/Stickers... ;)
Recently, a friend told me "Qt is great, but have no class to manage scanners with TWAIN/SANE" (Adn I think cups too).

Here is my question... Is there ANYTHING to start/get a scan from a scanner, directly from Qt ?

Thank you for you help guys :)

Cheers, Max13.

Bump :/ ?

I haven't seen such functionality in Qt yet. Probably there is some third-party Qt-based library that provides TWAIN/SANE access. If CUPS means printing this is "supported":http://doc.qt.nokia.com/latest/printing.html by Qt out of the box. You might take a look at the corresponding KDE applications - they are based on Qt.

Ah thank you.
And for scanning, is there such things supported by Qt ?

Thank you for your help.

Well, i don't think so. But just take a look at KDE, this is probably the most Qt-ish and up to date implementation you can get (libksane or similar).

Hi,
Maybe next will help to those interested to invoke TWAIN API methods in C++/Qt code and add TWAIN to Qt application:

My question is :

Can anybody share a piece of code and .pro file where you link to TWAIN library and call it ? A.W.
How to link to TWAIN library on Windows in .pro file?
