Style sheet not applied by inheritance ?

[moijhd]

Hi,

I have a MyWidget object which inherits from QWidget.

The following function is supposed to change the background color of a MyWidget object but it does not work.

Any remarks ?

Thanks.

// Set a color
void MyWidget::setColor(const QColor &color)
{
 
    // Prepare the style
    QString style = "background-color: rgb(%1, %2, %3);";
 
    // Set the color
    this->setStyleSheet(
                style
                .arg(color.red())
                .arg(color.green())
                .arg(color.blue())
                );
 
      qDebug() << this->styleSheet();
}

// Set a color
void MyWidget::setColor(const QColor &color)
{

    // Prepare the style
    QString style = "background-color: rgb(%1, %2, %3);";

    // Set the color
    this->setStyleSheet(
                style
                .arg(color.red())
                .arg(color.green())
                .arg(color.blue())
                );

      qDebug() << this->styleSheet();
}

PS : the debug instruction returns the correct style sheet.

Please define "does not work".

The background color of the widget does not change.

What I am trying to achieve here is the following : the user select a color (in a QDialogColor for example) and then I want to draw a rectangle with the chosen color. I did not find a appropriate tool. More precisely I would like to have a button instead...

If you want to draw a rectangle then reimplement the paint event and use QPainter::drawRect()
