    <p>First - I am assuming you are just trying to do this in pure python rather than in a c extension. So I am assuming you have loaded in the different records you are interested in into a set of python objects and your problem is that you want to see the higher level structure that is spread across these objects with bits here and there throughout the objects.</p> <p>So can you not simply load each of the records into a byte arrays type? You can then use python slicing of arrays to create a new array that has just the data for the high level structure you are interested in. You will then have a single byte array with just the data you are interested in and can print it out or manipulate it in any way that you want to.</p> <p>So something like:</p> <pre><code>a = bytearray(b"Hello World") # put your records into byte arrays like this b = bytearray(b"Stack Overflow") complexStructure = bytearray(a[0:6]+b[0:]) # Slice and join arrays to form # new array with just data from your # high level entity print complexStructure </code></pre> <p>Of course you will still ned to know where within the records your high level structure is to slice the arrays correctly but you would need to know this anyway.</p> <p><strong>EDIT</strong>:</p> <p>Note taking a slice of a list does not copy the data in the list it just creates a new set of references to the data so:</p> <pre><code>&gt;&gt;&gt; a = [1,2,3] &gt;&gt;&gt; b = a[1:3] &gt;&gt;&gt; id(a[1]) 140268972083088 &gt;&gt;&gt; id(b[0]) 140268972083088 </code></pre> <p>However changes to the list b will not change a as b is a new list. To have the changes automatically change in the original list you would need to make a more complicated object that contained the lists to the original records and hid them in such a way as to be able to decide which list and which element of a list to change or view when a user look to modify/view the complex structure. So something like:</p> <pre><code>class ComplexStructure(): def add_records(self,record): self.listofrecords.append(record) def get_value(self,position): listnum,posinlist = ... # formula to figure out which list and where in # list element of complex structure is return self.listofrecords[listnum][record] def set_value(self,position,value): listnum,posinlist = ... # formula to figure out which list and where in # list element of complex structure is self.listofrecords[listnum][record] = value </code></pre> <p>Granted this is not the simple way of doing things you were hoping for but it should do what you need.</p>

    1. COIt's a good solution for certain use cases, yes. The main differences from memoryview are: 1. this requires copying data around 2. when the new data structure is modified, it does not affect the original buffer, the modifications have to be copied back. In an ideal solution, I'd like to see these two properties.

    3. COThanks, it seems to be the only solution, since it is probably not doable using the built-in APIs.

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.
