Hi, It seems I can go with the solution I described. I don't need the tree view to be focused, so I just removed the “focus rect” (if that is the name Qt people know ;)) by setting the focus policy of the tree to Qt.NoFocus. I draw the “cursor” then myself by giving a different backlog in QAbstractItemModel::data. That makes anyway sense since the cursor position is part of my domain model. Thanks for help and inspiration! Dan

Hi, thank you for reply. Will try to reapply only changes as we did in the past in hope it will work. Will update this thread if manage to find something out.

@eduardo_parra said: but the cursor detect the margins What margins? Do you mean for something inside the docks?

Ok, thanks. This solved my problem

Its something completely custom. It does not have package manager.

In that case, I'd recommend to take a look at KDAB's blog entry about Qt Input Method In Depth The followup article will be even more useful, but this one is already a good starting point.

@SGaist Thank you !! It's ok now. I missed viewport...

Thanks. I can probably understand why Qt wouldn't want to allow the developer to block all (mouse) input, but docs are not clear about this issue.
