qt通过类名动态创建对象

#include "mainwindow.h" #include "ui_mainwindow.h" #include "QPushButton" #include "QCheckBox" #include "qcheckbox.h" #include <QDebug> MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , ui(new Ui::MainWindow) { ui->setupUi(this); QString abc = "QPushButton"; QByteArray a = "QPushButton"; Reflect::registerClass<QPushButton>(); QPushButton* object = (QPushButton*)Reflect::newInstance(abc.toUtf8()); // QPushButton* object = (QPushButton*)Reflect::newInstance(a); object->setGeometry(50,50,100,40); object->setText("我是动态的"); object->setParent(this); QPushButton* hh = new QPushButton(this); } MainWindow::~MainWindow() { delete ui; } void MainWindow::clicked() { qDebug()<<"haha"<<endl; // Reflect::registerClass<QCheckBox>(); // QCheckBox* check = (QCheckBox*)Reflect::newInstance("QCheckBox"); // check->setText("hhh"); // check->setParent(this); } void MainWindow::on_pushButton_clicked() { }
