QLineEdit background color role
Message 1 in thread
Isn't there a way to disable the background for a line edit? I want it
to display the text with the widget underneath showing through. Funny
enough, I can't even find a color role that affects the line edit
background? ideas?
thanks

QPalette::Base is the role you are looking for.

Got it
class Widget : public QWidget
{
Q_OBJECT
public:
Widget(QWidget *parent = 0)
: QWidget(parent)
{
QVBoxLayout *l = new QVBoxLayout(this);
QLineEdit *edit = new QLineEdit("This is a line edit", this);
QPalette pal = edit->palette();
pal.setColor(edit->backgroundRole(), Qt::transparent);
edit->setPalette(pal);
l->addWidget(edit);
}
void paintEvent(QPaintEvent *)
{
QPainter p(this);
p.fillRect(rect(), QColor("brown"));
p.drawLine(0, 0, width(), height());
p.drawLine(width(), 0, 0, height());
}
