我有时会使用windows gdi区域进行图形绘制和无效/验证。例如程序http://www.maxerist.net/main/soft-for-win/tubicus（oss）只使用区域（没有位图或屏幕外缓冲区）。该绘图使用FillRgn和FrameRgn进行，使用InvalidateRgn和CombineRgn进行无效和绘制，每个单元格（见屏幕截图）都是使用CreateEllipticRgn、CreatePolygonRgn和comineRgn创建的简单区域。
我计划将它移植到Linux。据我所知，Linux中有许多图形库。是否有支持类似窗口的区域？
谢谢
您想要使用X窗口系统，也就是X11，作为您的图形平台。它的客户端库称为Xlib。平台支持多边形区域。
有许多库是在Xlib之上编写的（Gtk、Qt、wxWindows等），但您总是可以将低级Xlib API直接用于其中任何一个库。Qt甚至支持椭圆区域。我不知道细节，但我想它是在X11多边形区域之上实现的。
Qt有很多绘画选项，使用QPainter和QPainterPath对象可能非常适合您。（Qt分布中有示例）。您可以组合（添加/相交/子行为）路径。
QGraphicsView框架也是一个不错的选择。
