[Qt-interest] QSortFilterProxyModel - the parent item does not match i want to go down to the child as well and filter

[Sajjad]

Hello Scott,

I have declare a slot against the line edit text changed signal to match
against the entered text to  the data string in the model and then
highlight.


I was wondering how to search  the custom model against  the entered string

Regards
Sajjad
