Question of Qt licensing on Qgis

[Denis Bourouffala]

Hello,

I have a question regarding QGIS and Qt licensing.

If I develop a plugin for QGIS that utilizes Qt, can I sell it without being obliged to provide the source code, or must I purchase a Qt commercial license?

Best Regards

[Emma Hain]

Apologies for this - it was sitting in the folder to be approved to be released. I have now resorted my filters in order for them to be brought to my attention asap

Hi Denis

You can sell it, but subject to GPL, so you MUST supply the source code if requested by a customer

or must I purchase a Qt commercial license?

 

No, you don't need a qt commercial license, because you are writing GPL code

Cheers
