Serialization
=============
One of the required features is to be able to persist and load a layout.
This can be done by means of the DockStore. A DockStore is able to load and save layouts.
For loading and saving, the most simple xml serializer is used: xml.parser or etree::
<?xml version="1.0" encoding="utf-8">
<layout>
<frame x="0" y="0" width="0" height="0">
<paned orientation="horizontal">
<group size="23%">
<item id="identifier" title="" icon="" tooltip="" pos="1" vispos="2" />
</group>
<paned size="67%" orientation="vertical">
<group size="100%">
<item id="identifier2" title="" icon="" tooltip="" pos="1" vispos="2" />
</group>
</paned>
</frame>
<frame floating="true" x="0" y="0" width="0" height="0">
...
</frame>
</layout>
The layout can be set up automatically as far as DockFrame, DockPaned, DockGroup and DockItem is concerned. The contents of a single DockItem is harder to construct. For this the DockStore needs to consult a delegate object that implements the DockStore protocol::
class DockStoreDelegate(object):
def load(self, id): pass
Open items:
* It's interesting to see to what extend the current GUI builder code can suite us.
