[QGIS-Developer] Create a custom python based widget to be used in attribute forms

[Bo Victor Thomsen]

(Sorry about the hijacking of another thread)... Here is my question 
(again...)

Hi List -

I remember (very vaguely) an blog-article describing how to make a
custom pyqt widget to use in QGIS attribute forms.

I'm not talking about designing a custom form with python logic (I know
how do that) but making a custom widget as a replacement for one of the
build-in widget like calendar or value-relation widgets a.o.

My goal is to make a widget based on a qtreeview or qtreewidget that is
populated using a layer with three columns "parent", "key" and "value",
where "parent" is used to build the tree structure.

Something like the existing value-relation widget but with a treewidget
instead of a combobox, that can be used to create multi step
"drill-down" functionality.

However, I can't find the article. Is there anyone on this mailing-list,
that can point me in the right direction ?

(The correct course of action would be to program it in C++. However I
can't find the time - or intellectual energy -  to brush up my very
rusty knowledge of C++ :-/)
