<![CDATA[How to get a 1 pixel black border on a frameless dialog?]]>I have a couple of instances of a Dialog which I don't want a titlebar or widgets, so I call:

setWindowFlags(Qt::FramelessWindowHint);

In the class constructor, however I would like a single pixel, maybe 2 pixel black border around the dialog just to make it clear and standout when it overlays another dialog of the same background colour.

I've tried setting the style sheet using:

setStyleSheet("QDialog {border:1px solid black}");

It doesn't do anything.

void YourWidget::paintEvent(QPaintEvent *)
{
QStyleOption opt;
opt.init(this);
QPainter p(this);
style()->drawPrimitive(QStyle::PE_Widget, &opt, &p, this);
}
