推荐答案

cairo的最新版本通过允许绘制到使用cairo_qt_surface_create(QPainter *painter)创建的表面来支持Qt:您可以检查相关的头文件

Recent version of cairo supports Qt by allowing to draw to a surface created with cairo_qt_surface_create(QPainter *painter): you can inspect the relevant header file here. There's no documentation because this feature is still experimental and disabled by default (you should compile cairo yourself explicitely enabling the Qt support with configure --enable-qt.
