How do I set an QImage on a QLabel?

Hi

How do I set an QImage on a QLabel?
I'm really stuck!

Cheers

Try this:

Code:

---

int main(int argc, char** argv)
{
  QApplication app(argc, argv);
  QPixmap image("image.jpg");
  QLabel imageLabel();
  imageLabel.setPixmap(image);
  label.show();
  return app.exec();
}

---

QImage is designed and optimized for I/O, and for direct pixel access and manipulation, while QPixmap is designed and optimized for showing images on screen

I'm trying to use QImage instead of QPixmap, because it is optimized for pixel manipulation.
I tried to create a QImage:

QImage image;
image = QImage(100, 100, QImage::Format_ARGB32);
image.fill(qRgb(0, 100, 100));

and then created a QLabel to set the image:

QLabel *labelImagem=new QLabel;
labelImagem->setPicture(image);

but it won't compile. Any suggestions what is going wrong?

Cheers

What is the error message and what do you make of it? What are the argument types for setPicture()?

Surprise, surprise. QImage != QPicture! use:

Code:

---

QLabel l;
l.setPixmap(QPixmap::fromImage(yourImage));
