Is it possible to add QPen property and stylize it using qss?

I'm trying to set color and width to QPen using qss.
I've added a QPen property like below

Code:

---

Q_PROPERTY( QPen hoveredContentBorder READ hoveredContentBorder WRITE setHoveredContentBorder NOTIFY hoveredContentBorderChanged )

---

It doesn't work.

I also added QBrush property like below and it's working fine.

Code:

---

Q_PROPERTY( QBrush hoveredContentFill READ hoveredContentFill WRITE setHoveredContentFill NOTIFY hoveredContentFillChanged )

---

I'm using Qt 5.10.1.
Thanks in advance.

Hi, what doesn't work? What did you do the QPen? What did you expect?
