[SOLVED]PDF files how to

[toho71]

Is there a easy way to open and show a pdf file in qt.

In that case some simpel code would be nice or some hints.

I have heard about poppler but haven't read something yet

Well, why don't you just start doing so?

http://poppler.freedesktop.org/
http://people.freedesktop.org/~aacid/docs/qt4/
http://doc.qt.nokia.com/qq/qq27-poppler.html

There is no build-in, easy way to do it. However, you are not the first integrating poppler in a Qt application, so I suggest you do a bit of searching for code on that and use that as inspiration.

You can try showing that on QWebView, some say it's possible, but as for me, I failed that

[toho71]

Thanks all of you.
I give poppler a try.
Is it free to use.

If you do not need to integrate it tightly into your application, then "QDesktopServices::openUrl() ":http://doc.qt.nokia.com/4.7/qdesktopservices.html#openUrl could be an option too. It opens the PDF in the default application for such. The viewer is run as an external application though and you do not have any control over the app.

[toho71]

Great
I though about this solution and maybe I use it instead.

Could you Volker check this thread to and give me a Solution perhaps.

I'm stuck

bq. If you do not need to integrate it tightly into your application, then QDesktopServices::openUrl() [doc.qt.nokia.com] could be an option too. It opens the PDF in the default application for such. The viewer is run as an external application though and you do not have any control over the app.

This was very easy to use

And another question
Is poppler free to use in a distributed system ( No easy answer to this)

[lgeyer]

I'm not quite sure what the "distributed system" should be in your case but poppler is licensed under the terms of the "GPLv2":http://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html. This basically means that if you want to use poppler in a "commercial application":http://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html#GPLCommercially you will have to release your source code under the terms of the GPL as well. IANAL.

[toho71]

Thank you.
My application will be a standalone application on many machines.
Could I use this lib then without sharing the sourcecode

Answer
bq. Thus, for instance, you must make the source code available to the users of the program as described in the GPL, and they must be allowed to redistribute and modify it as described in the GPL.

[lgeyer]

It depends. If you create an application just for your company and it is just used internally there is no need to release any source code. But if you release the source code or the product to the public you will have to release the source code under the terms of the GPL as well. IANAL.
