QLineEdit and findChild()

Question

I am trying to set the text of a line edit that is found using findChild()

mainwindow.cpp

void MainWindow::setValue(QString line, QString value){
    QLineEdit * edit = centralWidget()->findChild<QLineEdit *>(line);
    edit.setText(value);
}

However, I get an error on edit.setText(value); saying left of .setText must be class/struct/union.

How do I properly set the text of the child name line to be value ?

您需要使用->运算符，因为edit是一个指针：

edit->setText(value);
