qt422 - model/view newbie question
Message 1 in thread
Hi,
I just port a Qt3 tree container to Qt4.
don't want to use model view functionnalities.
I don't see how to parse items in a qtreeview simply under qt422.
I don't have any model, just want to parse the tree in a qtreeview?...
I want to get items of view to get some associated info. no more
is someone can give me help, good link in doc?
thank you,
Veronique.

Hi,
You might want to take a look at the convenience version with a
built-in model. It's called QTreeWidget and the documentation can be
found here: http://doc.trolltech.com/4.2/qtreewidget

thank you, I saw this convenient class doc.
I did'nt find some function that could get all items.
it seams that I may parse recursively items doing something like this:
parsetreewidgetfuntion
{
for(i=0,i <myqtreewidget->topLevelItemCount (),i++)
{
parse recursively items....
}
}
I would like to verify if there is or not a "getallitems" method like.

There is an utility class called QTreeWidgetItemIterator for iterating
through the whole tree or parts of it according to the given flags:

Thank you JP and Andreas.
I didn't see this class (that is just after QTreeWidgetItem in classes
list :-[ :-[ )
have a nice day.
Veronique.

No, but you could use the QTreeWidgetItemIterator to iterate over all
items.
