How to make QCheckBox readonly, but not grayed-out

Any good way to make a checkbox readonly, but also not grayed-out (hardly visible).

  1. I have used setEnabled(bool) which works, but the checkbox then is grayed-out and hardly readable
  2. I can react on a toggle signal and reset the state. But I would need a kind of flag to determine if the box is read-only and then reset the check state, means I need to create my own CheckBox class.

  3. setCheckable does not work either, it does not allow me to set a checked state at all:

        cb = this->ui->cb_RealWorld->isCheckable();
    this->ui->cb_RealWorld->setCheckable(true);
    this->ui->cb_RealWorld->setChecked(someValue);
    this->ui->cb_RealWorld->setCheckable(cb);

So the best thing I have is to use enable/disable and accept the grayed out style.

------- Edit -------

Following the stylesheet examples I was hoping I could set the style of a disabled checkbox like the one of an enabled. Failed so far to do so. More specific: Changing the icon like in the examples does not work for me, maybe because I am using Windows and the icons are not available under the path as in the examples.
