ObjectListView in closed-source program to sell [closed]

Question

Is it possible to use ObjectListView, which uses the GPL v3 license, legally in a closed-source program that will be sold?

If so, what has to be done to make sure to not violate the license?

Answer 1

ObjectListView has a GPL license so that it is usable by all free software.

Commercial licenses are available, with payment being related to the size of the organisation that wants the licenses.

If you cannot afford any license, we can still work something out. I've never denied a commercial license to anyone who wanted one.
