Overriding Stylesheet settings

leinad

Hi,

I have an app that is governed by a stylesheet. Is there a way I can override the color from the stylesheet setting for a specific tab? I already sub-classed QTabBar to use paintEvent. If I select a stylesheet that does not define a background color for the tabs the paintevent works fine, however if I define a background color in the stylesheet for the tabs then the paintEvent does not seem to override the color. I had a similar ticket opened previously but now redefined my requirements.

I really would appreciate any help you can provide.

paintEvent(QPaintEvent * /event/)
{

QStylePainter painter(this);
QStyleOptionTab opt;


for (int i = 0; i < count(); i++)
{
    initStyleOption(&opt, i);
    painter.save();

    if (i == changeColorTabIndex)
    {
        if (clearTabBackground == false)
        {
            TENA::Console::CustomTabBar::setStyleSheet("");
            painter.fillRect(tabRect(i), QColor(255, 255, 0));  //create a yellow background   (does not work with a stylesheet defined for a background color for the tabs.
        }

    }

    painter.drawControl(QStyle::CE_TabBarTabShape, opt);  //sets tab shape
    painter.drawControl(QStyle::CE_TabBarTabLabel, opt);  //sets tab text
    painter.restore();
}

}

So far as I am aware (I stand to be corrected) all stylesheet settings override anything (matching) from styles/paint events?

Thanks, I'll wait and see if someone has any ideas. I hope there is a way :)

One other question, when I don't use a stylesheet, after I paint the tab yellow, the color seems to bleed above the tab borders. Is there a way I can fix that?

painter.fillRect(tabRect(i), QColor(255, 255, 0)); //create a yellow background

This is what it looks like.

Please any help would be appreciated.

I think I figured out the issue, seems the stylesheet had a border if not selected the size was 2px larger which was filled in. One must be careful to look at the stylesheet settings when making custom chnanges.
