这是一个句柄图形对象及其子代的机器生成表示。注意，当这些对象被重新创建时，句柄值可能会发生变化。这可能导致写入取决于手柄的价值的时候，对象是保存任何回调的问题。通过将输出保存为一个GUI文件来解决这个问题。(This is the machine-generated representation of a Handle Graphics object and its children.　Note that handle values may change when these objects are re-created. This may cause problems with any callbacks written to depend on the value of the handle at the time the object was saved. This problem is solved by saving the output as a FIG-file.)
