Bitmap - buttons for the Titlebar -Bitmap- buttons for the Titlebar

Use Qt in image development.  QPixmap largepixmap;  QPixmap smallpixmap;  QPixmap maskpixmap;  QPixmap zoompixmap;  QPoint offset(0,0);  QPoint dragpos(150,150);  QPoint set(90,50);    //加载图片：  largepixmap.load("ImagesMainGui.png");  smallpixmap = largepixmap.scaled(largepixmap.size()/1.2);  maskpixmap.load("ImagesMainGui.png");    //绘制底层图片（非放大镜区域图案）：  QPainter painter(this);  painter.drawPixmap(offset,smallpixmap);  painter.end();  //计算放大区域圆形的半径及所占矩形面积     int dim = qMin(width(), height());  int magnifierSize = dim * 5 / 6;  int radius = magnifierSize / 2;  int ring = radius - 15;  QSize box = QSize(magnifierSize, magnifierSize);
