QTreeView - branch buttons appearance and size

  • Hi all,

    I have implemented a QTreeView and I would like to change the size and appearance of the branch openers and closers.

    Not sure what they are called, on some platforms they are shown are + and - symbols in a box, on other platforms they are shown as a triangle which rotates. I would like to make sure it appears above a certain size on a specific platform or at least appears consistently across all.

    I have already tried changing the row height, but the actual +/- remains too small for usability on a touchscreen device.


  • You can do it styling QTreeView::branch see http://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qtreeview
