Q_PROPERTY的使用说明

MEMBER的使用

class MainWindow : public QMainWindow
{
    Q_OBJECT
    Q_PROPERTY(QString name MEMBER m_name)
private:
    QString m_name;
}

使用方法(见代码):

void MainWindow::on_pushButton_clicked()
{
    setProperty("name", "good");
}
 
void MainWindow::on_pushButton_2_clicked()
{
    QString strVal = property("name").toString();
}
