简单涂鸦板代码中创建颜色组合框的问题

raomarcus

void MainWindow::creatColorComboBox(QComboBox *comboBox)
{
    QPixmap pix(16,16);
    QPainter painter(&pix);
    painter.fillRect(0,0,16,16,Qt::black);   //先绘制一个16*16的小图片，然后给其涂色
    comboBox->addItem(QIcon(pix),tr("黑色"),Qt::black);   //再用该图片作为组合框条目的图标
    painter.fillRect(0,0,16,16,Qt::white);
    comboBox->addItem(QIcon(pix),tr("白色"),Qt::white);
    painter.fillRect(0,0,16,16,Qt::red);
    comboBox->addItem(QIcon(pix),tr("红色"),Qt::red);
    painter.fillRect(0,0,16,16,Qt::green);
    comboBox->addItem(QIcon(pix),tr("绿色"),Qt::green);
    painter.fillRect(0,0,16,16,Qt::blue);
    comboBox->addItem(QIcon(pix),tr("蓝色"),Qt::blue);
    painter.fillRect(0,0,16,16,Qt::yellow);
    comboBox->addItem(QIcon(pix),tr("黄色"),Qt::yellow);
    comboBox->addItem(tr("无颜色"),Qt::transparent);  //即透明
}这是该函数代码。已在头文件中对函数定义。提示的错误如下
