Can I use png files included in Qt package?

taichi

Hi everyone,

I am using Qt with the LGPL lisence in a commercial product.
In this case, can I use png files included in Qt package to icons of my product?
And if I want some customize to the file (for examle, put a tiny image on 'file' shaped png like icon overlay), does this mean violating LGPL?

Hi,

The LGPL covers code, not images.

Which .png files are you referring to? If you mean the Qt logo, that use is covered under http://qt-project.org/trademarkpolicy.html

Thank you for your reply.

I want to use png files under src folder (under src/gui/styles/images/ of Qt 4.8).

The LGPL covers code, not images.
Let me confirm whether this means I can use .png files or not?

Thanks.

However, you can contact them and ask for permission. If they give you permission, then you can use the images.

Anyway, if you are looking for free icons, try something like http://tango.freedesktop.org/
