我有一个三列的表视图;我刚刚使用这段代码写入到文本文件中:
QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::WriteOnly)) {
QMessageBox::information(0,"error",file.errorString());
}
QString dd;
for(int row=0; row < model->rowCount(); row++) {
dd = model->item(row,0)->text() + ","
+ model->item(row,1)->text() + ","
+ model->item(row,2)->text();
QTextStream out(&file);
out << dd << endl;
}
但是我无法成功再次读取相同的文件,我尝试了这段代码,但我不知道它的问题所在。
QFile file("/home/hamad/lesson11.txt");
QTextStream in(&file);
QString line = in.readLine();
while(!in.atEnd()) {
QStringList fields = line.split(",");
model->appendRow(fields);
}
请帮忙,谢谢!
