    <p>I've run into a problem that has just been hell trying to figure out. In <code>event_init</code>, I found that calling <code>PyModule_AddObject</code> fails no matter what I do to the types and module creation. Trying to further isolate the problem, I figured out that it's only my custom types being added that cases it to crash (adding <code>Py_True</code> runs fine), and it's the manipulation of the module's dictionary that's actually causing it to crash (the internal call to <code>PyDict_SetItem</code>)</p> <pre><code>#include &lt;Python.h&gt; #include &lt;structmember.h&gt; struct pyEventProxy{ PyObject_HEAD }; static PyObject* pyKey_on(PyObject*,PyObject* args,PyObject* kwargs){ /* ... */ } static PyMethodDef pyKey_Methods[]={ {"on",(PyCFunction)pyKey_on,METH_STATIC,"Bind a keyboard event handler for one or more events."}, {NULL} }; static PyTypeObject pyKey_Type={ PyVarObject_HEAD_INIT(NULL,0) "key", sizeof(pyEventProxy), 0, 0, 0, /* tp_print */ 0, /* tp_getattr */ 0, /* tp_setattr */ 0, /* tp_reserved */ 0, /* tp_repr */ 0, /* tp_as_number */ 0, /* tp_as_sequence */ 0, /* tp_as_mapping */ 0, /* tp_hash */ 0, /* tp_call */ 0, /* tp_str */ 0, /* tp_getattro */ 0, /* tp_setattro */ 0, /* tp_as_buffer */ Py_TPFLAGS_DEFAULT, "Proxy object to access specific event functions.", 0, /* tp_traverse */ 0, /* tp_clear */ 0, /* tp_richcompare */ 0, /* tp_weaklistoffset */ 0, /* tp_iter */ 0, /* tp_iternext */ pyKey_Methods, /* tp_methods */ }; static PyModuleDef pyEvent_Module={ PyModuleDef_HEAD_INIT, "event", "Interact with Sandblox's event handling.", -1, 0, 0, 0, 0, 0 }; //Function called in another file to initialize the module void event_init(){ printf("Initializing key proxy type\n"); if(PyType_Ready(&amp;pyKey_Type)&lt;0){ printf("Key preparation failed\n"); return; } printf("Creating module\n"); PyObject* module=PyModule_Create(&amp;pyEvent_Module); if(!module){ return; } printf("Adding key proxy\n"); Py_INCREF(&amp;pyKey_Type); //This crashes PyModule_AddObject(module,"key",(PyObject*)&amp;pyKey_Type); } </code></pre> <p>I've been working on figuring this out for weeks, yet it's still beyond me what's even wrong. Another thing, the bare-bones example from the Python extension tutorial crashes just like mine does, but not for later examples. What am I doing wrong here?</p> <p>(in case this seems familiar, I asked this question a week ago and got a "tumbleweed" badge. So...)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
