通过字符串获取小部件

在for循环中,我可以构造一个字符串。

foreach (...) {
  QString str = "pushButton" + QString::number(count);
  // this gives pushButton1

  // Now I want to get the button widget that has this string as it's variable name 
  // and modify it in some way, e.g. change it's button caption

  str->setText("New Title");

  count ++;
}

编辑:下面是我如何创建按钮的

for (int i=0; i<total; i++) {
    QPushButton *btn = new QPushButton();
    btn->setObjectName("pushButton" + QString::number(i));
    ui->horizontalLayout->addWidget(btn);
}
