How to change QToolButton#qt_toolbar_ext_button size?

  • Hi, I set icons to the extension button in stylesheets, but the button is always so small, is there a way to change the size?

    I tried in the stylesheet:

    QToolButton#qt_toolbar_ext_button {
      min-width: 20px;
      width: 20px;
      min-height: 20px;
      height: 20px;

    Doesn't work.
