Using Qt CSS to set own Q_PROPERTY(QFont)

I'm using Qt 4.6.2 and i have problem with QCSS. I have own Q_PROPERTY(QFont myFont READ myFont SET setMyFont). I want to开发者_如何学编程 change it with QCSS but it doesn't work. I've tried using normal font syntax but it doesn't work. I've also tried few other combinations like:

qproperty-myFont: font(serif 20 1 0) font(serif 20 bold) QFont(serif 20 1 0) QFont(serif 20 bold) QFont(bold 20px serif)

etc.

Ok, after longer research i found methods QFont::toString and QFont::fromString. It's not so clean and "css nice style" but it works now:

qproperty-myFont: "serif,-1,14,5,0,0,0,0,0,0";

Where parameters are: font family, pointSizeF, pixelSize, QFont::StyleHint, QFont::Weight, QFont::Style, underline, strikeOut, fixedPitch, rawMode
