Qt4中的条形码生成

Question

Any ideas for barcode generation into a textbox in c++ under Qt4?

The idea is to have it in some kind of text format to save it and be able to read it later on.

What about generating the image for printing?

Thanks in advance.

Answer 1

Generating a barcode is as simple as using a barcode font . You can embed the font in your application, and create barcode wherever you can put text.

Answer 2

It depends on what kind of a barcode you are talking about, however, a search on Codeproject yielded this interesting library that is written in C#, however it can generate Code 39, Code 128, Interleaved 2 of 5, to name but a few. Perhaps, this could be recompiled to make it look like a COM object using Runtime Callable COM Wrapper (RCCW), meaning on the C++ side, it looks like a COM library? And hence interact with it from a QT/C++ runtime environment.

Hope this helps, Best regards, Tom.

请检查zint，可以在Sourceforge上找到它。

Answer 4

Generating barcode with Qt is quite easy - as Reverend Gonzo pointed out, you use a barcode font. Then you can paint it with QPainter onto anything. Or print it.
