Qt 实现 异形 窗体按钮

//关键部分代码如下
//设置异形窗体
//setWindowOpacity(0.5);//设置窗体透明度 0完全透明，1完全不透明
this->setWindowFlag(Qt::FramelessWindowHint);//无边框，隐藏标题栏,但工具栏，状态栏还在
ui->centralWidget->setStyleSheet(QString("#centralWidget{background-image: url(:/Image/image/mask1.png); "
"background-repeat: no-repeat;}"));
this->setAttribute(Qt::WA_TranslucentBackground);
this->resize(QPixmap(":/Image/image/mask1.png").size());//显示窗口跟图像大小一致
//异形按钮
QPixmap btnImg;
btnImg.load(":/Image/image/up.png");
ui->btn_up->resize(btnImg.size());
ui->btn_up->setMask(btnImg.mask());
ui->btn_up->setStyleSheet("background: transparent;background-image: url(:/Image/image/up.png);");
