QTreeView Fusion style vs. deprecated Plastique (Qt 5.2)

  • I haven't really touched QStyle related code before, so sorry if this is a very basic question.

    I saw that the Plastique style was removed and that it is recommended to use the new Fusion style. Overall, Fusion looks great but I would love to have QTreeView's expansion buttons as "+" rather than the arrows present in fusion.

    Is there a way to tweak just that aspect? And if I really want to get the plastique style, what do I have to do between getting the code from the qtstyleplugins repository and actual deployment so that it looks the same on the end-user's machine?
