您需要使用双缓冲区技术：
http://en.wikipedia.org/wiki/Multiple_buffering#Double_buffering_in_computer_graphics
那就是您有一个图像，然后绘制该图像：该图像是“后台”缓冲区。您可以使用很多方法来绘制图像。然后，在响应“绘制”信号的回调上，也就是说，实际上在图形存储器中绘制内容的方法只是将您的“幕后”图像丢了。
代码理论（ test.py ）：

依存关系：
Python 2：
sudo apt-get install python-cairo
Python 3：
sudo apt-get install python3-gi-cairo
现在执行：
python test.py
要么
python3 test.py
看起来像什么：
可以在http://cairographics.org/documentation/pycairo/3/reference/index.html中找到有关cairo的所有文档。
亲切的问候
