Hi, thank for your help
It works. Here the examples:

Qt Code: 
  1. /*Example vor copy one file
  2. 	 QString file = QFileDialog::getOpenFileName(
  3. 	 "/home",
  4. 	 "Images (*.doc)",                    
  5. 	 this,                    
  6. 	 "open file dialog",                    
  7. 	 "Choose a file" ); 
  8.  
  9. 	 QFileInfo fi( file);    
  10. 	 QString base = fi.fileName();              
  11. 	 QUrlOperator *op = new QUrlOperator();        
  12. 	 QString src = file;           
  13.  
  14. 	 QString target = "D:/temp/" + base;           
  15. 	 op->copy(src, target, false, false); 
  16. 	 */
  17.  
  18.  
  19. 	/*Example vor copy one or more files*/
  20. 	QStringList files = QFileDialog::getOpenFileNames(
  21.                             "All files (*.*)",
  22.                             "",
  23.                             this,
  24.                             "open files dialog",
  25.                             "Select one or more files to open" );
  26.  
  27.     QStringList list = files;
  28.     QStringList::Iterator it = list.begin();
  29.     while( it != list.end() ) {
  30.         QFileInfo fi( *it);  
  31.         QString base = fi.fileName();
  32.         QUrlOperator *op = new QUrlOperator();        
  33. 	 	QString src = *it;
  34. 	 	QString target = "D:/temp/" + base;           
  35. 	 op->copy(src, target, false, false);
  36.         ++it;
  37.     }
To copy to clipboard, switch view to plain text mode
