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:
struct {
const char* label;
const char* file;
}
command[] = {
#ifndef QT_NO_TEXEDITOR
{"Addressbook","(cd /home/addressbook; exec ./addressbook)"},
#endif
{0,0}
};
keyclass::keyclass( QWidget *parent, const char *name):
QWidget( parent, name)
{
setMaximumSize(640,480 );
setMouseTracking(TRUE);
QPushButton *textedit = new QPushButton( "Quit", this, "quit" );
textedit->setGeometry(10,80,100,20 );
textedit->setFont( QFont( "Times", 12, QFont::Bold ) );
connect(textedit, SIGNAL(clicked()),qApp, SLOT(quit()) );
QVBox *vb1 = new QVBox(this);
vb1->setGeometry(10,100,100,100);
QPushButton *pb=0;
int ih;
for(ih=0; command[ih].label; ih++)
{
pb = new QPushButton(command[ih].label,vb1,command[ih].file);
connect(pb, SIGNAL(clicked()), this, SLOT(execute()));
}
}
void keyclass::run(const char* cmd)
{
QString c = cmd;
c += " &";
system(c.latin1());
}
void keyclass::execute()
{
run(sender()->name());
}
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
PID Uid VmSize Stat Command

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,
