QT：代码动态管理控件

Qt Designer

Qt Deisigner

pushButton = new QPushButton(centralWidget);  pushButton->setObjectName(QStringLiteral("pushButton"));  pushButton->setGeometry(QRect(60, 40, 75, 23));  pushButton->setText("ok");

mainwindow.cpp

QPushButton * pushButton;  QWidget * centralWidget =ui->centralWidget;  pushButton = new QPushButton(centralWidget);  pushButton->setObjectName(QStringLiteral("pushButton"));  pushButton->setGeometry(QRect(60, 40, 75, 23));  pushButton->setText("ok");

Qt Designermainwindow.cpp

void MainWindow::on_pushButton_clicked()  {  }

ui_mainwindow.h

所以需要自己进行信号与槽的关联。

connect(pushButton, SIGNAL(clicked()), this, SLOT(on_pushButton_clicked()));
