QprogressDialog 居中显示

要使QProgressDialog居中显示，可以使用以下代码：

QProgressDialog dialog("对话框名称", "", 0, 最大范围, this);
dialog.setWindowFlags(Qt::FramelessWindowHint);
dialog.setWindowModality(Qt::WindowModal);
dialog.setMinimumDuration(0);
dialog.setStyleSheet("QProgressDialog{background-image: url(:/图片名称.png);}");
dialog.setFixedSize(500, 200);
dialog.move((this->width() - dialog.width()) / 2, (this->height() - dialog.height()) / 2);
dialog.show();

在这段代码中，我们使用`move()`函数将对话框移动到父窗口的中心位置，从而实现居中显示。
