Not able to fix my picture file to Wanted resolution

houmingc

Need to fix a picture to a resolution: 1366 by 254 urgently.
It's currently maximized to the screen.
Below is my code. Please kindly pin-point my error.

         QPalette pal=palette();
         pal.setColor(QPalette::Background,Qt::white);
         setPalette(pal);
         setAutoFillBackground(false);
         m_pPalette	= new QPalette();
         m_pPixmap		= new QPixmap(":/file/rightp.png");
         m_pPalette->setBrush(QPalette::Background,QBrush(*m_pPixmap));
         setPalette(*m_pPalette);
         QWidget *centralWidget = new QWidget(this);
         QGridLayout *layout = new QGridLayout();
         centralWidget->setLayout(layout);

Hi,

What about the QImage::scaled function ?

houmingc

Did two thing.

Using recommended code below, compilation Error appear ->"The program has unexpectedly finished"
QImage myImage;
myImage.load(":/file/rightp.png");
myImage.scaled(1366,254, Qt::IgnoreAspectRatio, Qt::SmoothTransformation);
How to scale stylesheet to 1/4 of mainwindow using below code

MainWindow w;
w.setStyleSheet("background-image:url(./file/left.png)");
w.show();
