Display QImage with QtGui

Question

I am new to Qt, and I am trying to create a simple GUI Application that displays an image once a button has been clicked on.

I can read the image in a QImage

Answer 1

One common way is to add the image to a QLabel widget using QLabel::setPixmap(), and then display the QLabel as you would any other widget. Example:

#include 

int main(int argc, char *argv[])
{
  QApplication app(argc, argv);
  QPixmap pm("your-image.jpg");
  QLabel lbl;
  lbl.setPixmap(pm);
  lbl.show();
  return app.exec();
}
