[Qt-interest] QDialog with background image

[David Boosalis]

Don't know about style sheets but you could just implement your own
resizeEvent and paintEvent().  For example:

class Dialog : public QDialog {
public:
  Dialog(QWidget *parent=0):QDialog(parent) {
    QGridLayout *grid = new QGridLayout();
    setLayout(grid);
    QPushButton *startB = new QPushButton("Start Me", this);
    grid->addWidget(startB,0,0,Qt::AlignCenter);
    pixmap = QPixmap("mybackground.png");
  }
protected:
  void resizeEvent(QResizeEvent *re) {
    pixmap  = pixmap.scaled(re->size(),Qt::KeepAspectRatioByExpanding);
  }
  void paintEvent(QPaintEvent *re) {
    QPainter painter(this);
    painter.drawPixmap(0,0,pixmap);
  }
private:
  QPixmap pixmap;
};

int main(int argc, char *argv[])
{
  QApplication app(argc,argv);
  Dialog *dialog = new Dialog();
  dialog->show();
  app.exec();

}
