    Qt Code:
    1. #include "visionneur.h"
    2.  
    3. Visionneur::Visionneur(): QWidget()
    4. {
    5.  
    6. m_ouvrir=new QPushButton("Ouvir une image",this);
    7. QObject::connect(m_ouvrir,SIGNAL(clicked()),this,SLOT(ouvrir()));
    8. m_contenu=new QLabel(this);
    9. m_contenu->setFrameShape(QFrame::Panel);
    10. m_contenu->setPixmap(QPixmap("image.png"));
    11.  
    12. }
    13. void Visionneur::ouvrir()
    14. {
    15. QString image = QFileDialog::getOpenFileName(this, "Ouvrir un fichier", QString(), "Images (*.png *.gif *.jpg *.jpeg)");
    16.  
    17. }

    Default Re: [problem]displaying image with Pixmap

    possible issues:
    * make sure image.png is in the directory you call your program from
    * set a layout on your widget
    * check that your Qt build supports .png
    try
    Qt Code:
    1. QLabel *l = new QLabel;
    2. l->setPixmap(QPixmap("image.png"));
    3. l->show();
    To copy to clipboard, switch view to plain text mode 
    Does this show the image?
