Barcode library

**NoRulez** · 4th February 2010, 16:05

Hey @all,

did anybody know a barcode library which is under LGPL or can be used in commercial products?
Maybe someone knows how to generate barcodes in Qt?
Currently I use Qt 4.6.1 and the library should also be run on Windows/Linux/Mac

Thanks in advance

Hi,

I don't know which model you need, but you can use font of characters like this:

Qt Code:

Switch view

QFont barCodeFont("c39hrp24dhtt", 40, QFont::Normal);

QFont barCodeFont("c39hrp24dhtt", 40, QFont::Normal);

To copy to clipboard, switch view to plain text mode

and use it to write a bar code like a text.

Try this link:

Hi,

If any old barcode will do then try the EAN13 example shown in the Wiki section (I lashed up a trivial front end and posted it in the Software section if it's any use). If you need it to identify items in the real commercial world you will propably have to register your company and get a company ID code to embed in the barcode - this will probably cost a far bit of money !

@ SteveH: On the wiki: http://wiki.qtcentre.org/ there is an example of the EAN-13. I need it for example Code 39 and so on.

Why not go to a professional barcode library site for help? I was wondering if you could use a third party barcode library? Would such tool be ok for you?

Zint and Zxing are comparatively popuplar barcode libraries. Or you can download a barcode font on your system, then the barcode generating function can be integrated into your project. It is not difficult to do so.
