frage/hilfe zum kcolorpatch

[dgrat]

ich habe eigentlich nur zwei fragen, warum funktioniert meine qt funktion nicht?
ich habe doch gar keinen fehler

.ui/form1.h:47: error: ISO C++ forbids declaration of `string' with no type
.ui/form1.h:47: error: `string' declared as a `virtual' field
.ui/form1.h:47: error: syntax error before `(' token

und wie kann ich den colorpatch mit der "standartfarbe" umfärben, ich krieg die funktion nicht unter slots.
eigentlich heißt die funktion zum färben doch

QColorchanged ( const char * name )

, da müssten doch strings auch funktionieren? oder

[cpp]string Form1::connection_status()
{
char buffer[8096];
string status; //zeile 47
string ready = "operational";
string init = "initializing(INITIALIZING)";
string un_plugged = "Pre-firmware device";
//string working = "Connection seems to be already started!";

string sbuffer;

FILE *eaglestat;
eaglestat = popen( "eaglestat", "r" );

if(eaglestat == NULL) {
//warnung einfügen
exit(0);
}

/* Read pipe until end of file. End of file indicates that
* FILE closed its standard out (probably meaning it
* terminated).
/
while( !feof( eaglestat ) ) {
if( fgets( buffer, 8096, eaglestat ) != NULL );
sbuffer += buffer;
}
/* Close pipe/
pclose( eaglestat );

//operrational
bool adsl_ready = (sbuffer.find(ready) != string::npos);
if(adsl_ready)
status = "green";
//initializing
bool adsl_init = (sbuffer.find(init) != string::npos);
if(adsl_ready)
status = "yellow";
//unplugged
bool adsl_nw = (sbuffer.find(un_plugged) != string::npos);
if(adsl_ready)
status = "red";
//working
//bool adsl_working = (sbuffer.find(working) != string::npos);

return 0;
}[/ccp]

ich bitte um verzeihung:

string Form1::connection_status()
{
  char buffer[8096];
  string status;//zeile 47
  string ready = "operational";
  string init = "initializing(INITIALIZING)";
  string un_plugged = "Pre-firmware device";
  //string working = "Connection seems to be already started!";

  string sbuffer;

  FILE *eaglestat; 
  eaglestat = popen( "eaglestat", "r" );

  if(eaglestat == NULL) {
	//warnung einfügen
    exit(0);
  }

  /* Read pipe until end of file. End of file indicates that
  * FILE closed its standard out (probably meaning it
  * terminated).
  */
  while( !feof( eaglestat ) ) {
    if( fgets( buffer, 8096, eaglestat ) != NULL );
    sbuffer += buffer;
  }
  /* Close pipe*/  
  pclose( eaglestat );

  //operrational
  bool adsl_ready = (sbuffer.find(ready) != string::npos);
  if(adsl_ready)
     status = "green";
