測試當前系統支援的風格：

#include "mainwindow.h"
#include <QApplication>
#include <QStyleFactory>
#include <QDebug>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QStringList keyList = QStyleFactory::keys();
 
    for(int i = 0; i < keyList.length(); i++)
    {
        qDebug(keyList.at(i).toUtf8());
    }
 
    // 設定全域性風格
    QApplication::setStyle(QStyleFactory::create("Fusion"));
 
    MainWindow w;
    w.show();
 
    return a.exec();
}
