[Qt-interest] [QtS60-feedback] how to get the selection change event for listview in Qt

[Ramesh]

Hi,

Now one problem is solved, but it seems that I am stuck in small problem
some were
I have got the way to take the selectionitemchanged and currentitemchanged.

I have understand like this, but not sure it may be wrong, please correct if
I am wrong.

Currentitemchage takes place when the userclicks on the cell or when the
item updated?

And I want to get both the previous and	current item, only when the user
clicked on item. But if I do movement of keyboard also I am facing the
Same problem, that is I am getting current item change..

So how to avoide keyboard events to come to currentitemchange?

Hi, 

The "current item" and "selected item" are different concepts in Qt. Please
have a look at this doc:
http://doc.qt.nokia.com/4.6/model-view-selection.html

The keyboard navigation only changes "current item", not "selected item". If
you need that feature, I think you need write your own code to update
"selected item" when you change the "current item".

Regards,
Liang

Hi,

QItemSelectionModel::selectionChanged is a signal. Did you connect it to a
slot in your code? That would be the correct way.

It is not an 'event' in the classical sense. Event function names in Qt
would usually have a "Event" at the end, and you can intercept those events
by overriding those functions in the derived class.
