Mananing multiples Uis or using QGraphicsview ?

[aftalib]

here's what i'm trying to do :

AntArrayDialog w1;
connect(ui->treeView,&TreeView::currentItemChanged,&w1,&AntArrayDialog::setFileName);

so let met explain : AntArrayDialog is my first Window. i am declaring it in order the method that i want to use here, which is setFileName

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)

but this code doesnt work. i know that what you wrote is correct but i dont know how to use it in my case

@aftalib does your ui treeview is promoted widget?

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.

[aftalib]

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.
