Canvas 这东西是qt3时代的了吧，现在已经被QGraphics框架代替啦，楼主看看新的吧

bool save(string filename)
Save the current canvas content into an image file filename. The saved image format is automatically decided by the filename's suffix.
Note: calling this method will force painting the whole canvas, not just the current canvas visible window.
不知道这个有没有帮助。
楼上这是QML中的，和Qt3不一样。
