Hiya world ....
I have just started to do my own Qt projects....and I crossed a lot of problems realy !!
Okey , without be long..i give you my source code..
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.                     }
  18. Visionneur::~Visionneur()
  19. {
  20.                          }
To copy to clipboard, switch view to plain text mode
