[提问]如何根据QByteArray中数据改变标签颜色 [复制链接]

int t = 0;
      if((t = temp.indexOf("06", t)) != -1)  {
QPalette pal1;
      pal1.setColor(QPalette::Text, QColor(106,255,106));
      ui->lineEdit_4->setPalette(pal1);
      ui->lineEdit_4->setText("AAAA");
  }
      else if((t = temp.indexOf("02", t)) != -1)
      {
          ui->lineEdit_4->clear();
          QPalette pal1;
          pal1.setColor(QPalette::Text, QColor(106,255,255));
          ui->lineEdit_4->setPalette(pal1);
          ui->lineEdit_4->setText("BBB");
      }
      else
++t;


不变色……入个条件一符合的话就不变了，是咋回事
