How to print barcode on the page or pdf document?

Mucip

Hi,
I searched the forum but usually old posts and reading samplas. Not writing?!

Well, I need to print order form on the page. But I want to print order number as barcode on the same page too.

Any advice?...

Hi
There are many barcode formats
so which one do you need ?

Some are easy to generate "manually"

Anyway, i personally like
https://github.com/zint/zint

Hi @mrjj ,
I checked zint infact but did not understand how to use?!...
How can I use it in my source code?...

Hi
Well you can build lib with cmake.
there should be cmake project file somewhere.
its a c api so its a bit "raw"

Hİ @mrjj ,
Well, is there any sample how to use this library in Qt?

It must be a easier way to print barcodes in Qt!...

@Mucip The examples are right there: http://www.zint.org.uk/Manual.aspx?type=p&page=5
They do not use Qt, but it is just C++.
If you think Qt should support bardcodes you can file a change request or even submit a patch.

Hi,
I think I can do it with Zint CLI

http://www.zint.org.uk/Manual.aspx?type=p&page=4

It creates the barcode png of the requested data very easilly.
By the way there is qt GUI version too. But I couldn't run it anyway. :)

Hi,
I tryed to use zint as below but did not get success?!

QProcess process;
process.setWorkingDirectory("D:\\ProgramFiles\\Zint\");
process.start("zint.exe", QStringList() << " -o c:\\sil\\kod.png -d 'CSI0070-1200'");

Why?...

@Mucip
Hi
QProcess has error signal you can try to hook up to and see what it says.
often that gives clues to what happens.

@Mucip said in How to print barcode on the page or pdf document?:

" -o c:\sil\kod.png -d 'CSI0070-1200'

This is wrong. Each parameter needs to be a string, not all in one string...

Mucip

Hi @jsulm ,
I changed do below but still nothing?!

process.start("zint.exe", QStringList() << "-o c:\\sil\\kod.png" << "-d 'CSI0070-1200'");

Hi @jsulm
Noe it worked... Thanks...

process.start("zint.exe", QStringList() << "-o" << "c:\sil\kod.png" << "-d" << "'CSI0070-1200'");

@Mucip
Windows: Install any downloaded Barcode font on your machine and print the order number with this font

Hi @Gerhard,
But in this case, you need to install same barcode fonts on every deployed machines. And this is not clear solution for me unfortunatelly... :(

Just as a note.
you can bundle the font with the app as a resource
and activate it via
int id = QFontDatabase::addApplicationFont(":/fonts/monospace.ttf");
