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

Simple, but complete example showing how to display QImage might look like this:

#include 
#include 

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QImage myImage;
    myImage.load("test.png");

    QLabel myLabel;
    myLabel.setPixmap(QPixmap::fromImage(myImage));

    myLabel.show();

    return a.exec();
}
