Using QStylesheet in Custom Style -> wrong palette.

jerebo

Hello all,

I use Qt4.8.4 to build an desktop application. I want to use QStyleSheet to apply a custom look and feel to my application. However I also need to draw custom ui elements in a MyStyle (which inherits from QWindowsVistaStyle). I want to style them with the values from my QStyleSheet.

What works:
I set the QStyleSheet to my QApplication, it gets correctly applied on my QWidgets as long as I paint default elements through MyStyle.
But requesting the palette and painting i.e. a rectangle by my self I still get the default style configuration.

QStyleSheet
@
QWidget {
background: #e18918;
}
@

Some draw.
@
void MyStyle::drawPrimitive(QStyle::PrimitiveElement element, const QStyleOption *opt,
QPainter *p, const QWidget *w) const
{
QWindowsVistaStyle::drawPrimitive(element,opt,p,w);

qDebug() << opt->palette.background().color;

}
@

Painting the item with the default element provides me the correct orange color, however the background color in opt is still default gray.

How can I read / get the correct value from the QStyleSheet?

Thanks,

Jeremias

Ok,

i checked some code... it looks like that you can not use CSS Styles within custom widgets...

@ if (QStyleSheetStyle* cssStyle = qobject_cast<QStyleSheetStyle*>(style)) {

        cssStyle->styleSheetPalette(this, &opt, &opt.palette);

    }

@

seems to be the magic, but QStyleSheetStyle is only private, is there any public interface?

Best,

Jeremias
