Mananing multiples Uis or using QGraphicsview ?

[nagesh]

@aftalib does your ui treeview is promoted widget?

in this current window, we have a TreeView, and i also have a treeview class where i reimplemented the eventFilter() method in order to get the signal that you see in the connect (&TreeView::currentItemChanged)

[aftalib]

@nagesh i didnt know about the promoting widget mechanism. how can i do this in my case ?

By reading: https://doc.qt.io/qt-5/designer-using-custom-widgets.html

ive tried this but it really doesnt solve my problem. it says that i have an "undefined reference" in my ui_ file

read again and think over on how we should help you with this information.

what i should do according to this is promote my TreeView that is in my Ui with my treeView class right ?

I don't understand what you're trying to tell me.

The documentation clearly shows you how to promote a QTreeView to a custom TreeView. That your custom TreeView must derive from QTreeView then should be out of question then.

i'm sorry, i really dont understand the concept behind this. What i have is :

a Ui File, which i have put a normal TreeView inside of it

a treeview.h and treeview.cpp file where i have redefined the eventFilter() method in order to get the signal i want.

what is the custom TreeView youre talking about ?

a custom TreeView is a class derived from QTreeView.

What does this mean?

QObject::eventFilter isn't usually involved in application code related to signals and slots.
