qt鼠标模拟点击button控件

在Qt框架中，你可以通过QMouseEvent或相关的信号槽机制来模拟鼠标点击按钮（QPushButton）的行为。以下是一个简单的示例：

#include <QObject>
#include <QPushButton>
#include <QEvent>

class MouseSimulator : public QObject {
public slots:
    void clickButton(QPushButton *button) {
        QMouseEvent event(QEvent::MouseButtonPress, button->geometry().center(), Qt::LeftButton);
        QApplication::sendEvent(button, &event);

        // 等待一段时间模拟按下并保持
        QThread::sleep(500); // 假设这里你想让按钮"按住"500毫秒

        event.type = QEvent::MouseButtonRelease;
        QApplication::sendEvent(button, &event);
    }
};

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    QPushButton button("Click me");
    MouseSimulator simulator;

    // 将simulator的clickButton绑定到button的clicked信号上
    connect(&simulator, &MouseSimulator::clickButton, &button, &QPushButton::clicked);

    // 显示窗口并将按钮添加进去
    QWidget window;
    QVBoxLayout layout(&window);
    layout.addWidget(&button);
    window.show();

    return app.exec();
}
