hi,

i compiled and ported qt-embedded-free-3.3.5 to MIPS(DBAU1200 ) platform.i tried to execute the launcher code in the package.but could not execute it successfully. the following is my code:

Qt Code: 
  1. struct {
  2.      const char* label;
  3.      const char* file;
  4. }
  5. command[] = {
  6.  
  7. #ifndef QT_NO_TEXEDITOR
  8. 	{"Addressbook","(cd /home/addressbook; exec ./addressbook)"},
  9. #endif
  10. {0,0}
  11. };
  12.  
  13. keyclass::keyclass( QWidget *parent, const char *name):
  14. 	 QWidget( parent, name)
  15. {
  16. 	setMaximumSize(640,480 );
  17. 	setMouseTracking(TRUE);
  18. 	QPushButton *textedit = new QPushButton( "Quit", this, "quit" );
  19.     	textedit->setGeometry(10,80,100,20 );
  20.     	textedit->setFont( QFont( "Times", 12, QFont::Bold ) );
  21.     	connect(textedit, SIGNAL(clicked()),qApp, SLOT(quit()) );
  22. 	 QVBox *vb1 = new QVBox(this);
  23.          vb1->setGeometry(10,100,100,100);
  24.          QPushButton *pb=0;
  25.          int ih;
  26.          for(ih=0; command[ih].label; ih++) 
  27.            {
  28.               pb = new QPushButton(command[ih].label,vb1,command[ih].file);
  29.               connect(pb, SIGNAL(clicked()), this, SLOT(execute()));
  30.            } 
  31. }
  32.  
  33.  
  34. void keyclass::run(const char* cmd)
  35. {
  36. QString c = cmd;
  37. c += " &";
  38. system(c.latin1());
  39. }
  40. void keyclass::execute()
  41. {
  42. run(sender()->name());
  43. }
To copy to clipboard, switch view to plain text mode 

When i run this code on the host using QVFB. the application runs fine. i mean when i click the addressbook pushbutton,the addressbook application opens. but when i run it on board the application does not pop up. i entered ps command and got the following output:

sh-3.00# ps -ae

336 root 4868 S ./launcher
345 root 3088 R /home/addressbook/addressbook
346 root 388 R ps -ae
sh-3.00#
the process is running but there is nothing in the screen.

can anyone provide me any suggestion or solutions for this ?

thanks in advance,
