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

[KalinH]

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

Q_PROPERTY( QPen hoveredContentBorder READ hoveredContentBorder WRITE setHoveredContentBorder NOTIFY hoveredContentBorderChanged )

Q_PROPERTY( QPen hoveredContentBorder READ hoveredContentBorder WRITE setHoveredContentBorder NOTIFY hoveredContentBorderChanged )

To copy to clipboard, switch view to plain text mode 

It doesn't work.

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

Q_PROPERTY( QBrush hoveredContentFill READ hoveredContentFill WRITE setHoveredContentFill NOTIFY hoveredContentFillChanged )

Q_PROPERTY( QBrush hoveredContentFill READ hoveredContentFill WRITE setHoveredContentFill NOTIFY hoveredContentFillChanged )

To copy to clipboard, switch view to plain text mode 

I'm using Qt 5.10.1.
Thanks in advance.
