pygi-treeview-dnd

=================

GTK+ provides a `high-level DnD API `_

that makes implementing drag and drop on TreeView objects (lists, trees, etc)

significantly easier, and far less error prone. There are hundreds of lines of

code in GTK to implement this -- so 

Unfortunately, there's a longstanding bug in PyGObject that prevents python

programs from using this API. `See the bug report for details `,

but basically the SelectionData in drag_data_get is a copy instead of the exact

same SelectionData object, and GTK expects you to modify the original object.

This is a workaround that uses some metaclass magic, GTK internals, and ctypes

to patch up custom TreeStore/ListStore objects. It seems to work, and I plan

on using it extensively in Exaile. If it doesn't work well or if there are

issues, then I'll post a note on github.

Ideally, one day PyGObject will have a fix for this issue, and this package

will no longer be necessary.
