qt问题 急急 [复制链接]

char *p,*k;
QListViewItem *Item;
sprintf(p,"%02u:%02u:%02u.%02u",tail->TimeStamp.ti_hour,tail->TimeStamp.ti_min,tail->TimeStamp.ti_sec,tail->TimeStamp.ti_hund);
sprintf(k,"%3f,%3f",tail->Lat,tail->Lon)；
Item =new QListViewItem(ListView1,p,k);
请问p和k中的内容会在ListView1中显示？如果不会该怎么写，急！！！1

楼主,建议你先好好学习C++然后再接触QT
你的代码由许多初级错误

char *p,*k;    //！！！这里声明的char*,还没分配空间下边就开始用
QListViewItem *Item;
sprintf(p,"%02u:%02u:%02u.%02u",tail->TimeStamp.ti_hour,tail->TimeStamp.ti_min,tail->TimeStamp.ti_sec,tail->TimeStamp.ti_hund);
sprintf(k,"%3f,%3f",tail->Lat,tail->Lon)；
Item =new QListViewItem(ListView1,p,k);

QString & QString::sprintf ( const char * cformat, ... )
Safely builds a formatted string from the format string cformat and an arbitrary list of arguments. The format string supports all the escape sequences of printf() in the standard C library.

用QString,它也有Springtf函数
