Resizing Treeview icon

AbelMarnk

Hey, I am new to QT, i have been playing around with widgets now, more specifically those i intend to use for a project i am working on, i wanted to know if there was a way to resize the icon in a Treeview, i think it might be possible by fiddling with the drawing of the widgets, but like i said i am new and i don't know much about that, so i wanted to know if could do it without resorting to a custom drawing
Here is the relevant part of the code:-
mainwindow.ui:-

ui->treeView->showNormal();

}

I would appreciate any help or advice, thanks.

Okay, i found a way to do it i was looking in the QStandardModel documentation, thinking it would be there, but I found it in the QAbstractItemView documentation.
