QTreeView branch drawing... missing branch?

Dariusz

Hey

So I've run in to alittle bit of a hiccup...

I'm using custom QStyledItemDelegate on my QTreeView, and I think it caused some issues...

When I draw my items I'm missing alternativeBackgroundColors + vertical branch line without anything next to it...

A standard QTreeView renders properly :

I literally have no idea how to dig in to it... any hints? :- ))))

TIA


QTreeView::branch:has-siblings:!adjoins-item {
    background: white;
    border-image: none;
	image: none;
}
 
QTreeView::branch:has-siblings:adjoins-item {
    background: white;
    border-image: none;
	image: none;
}
 
QTreeView::branch:!has-children:!has-siblings:adjoins-item {
    background: white;
    border-image: none;
	image: none;
}
 
 
QTreeView::branch:has-children:!has-siblings:closed,
QTreeView::branch:closed:has-children:has-siblings {
    background: white;
    border-image: none;
}
 
QTreeView::branch:open:has-children:!has-siblings,
QTreeView::branch:open:has-children:has-siblings  {
    background: white;
    border-image: none;
}

Running this code result in :

I'm not getting any of the has-siblings:adjoins-item / etc items.

Hi,

A good starting point would be to share your delegate code. That way more eyes may spot what is going wrong.

@SGaist QStyledItemDelegate paints that branch? :O I never did any call to paint in in paint() function, how/where does it paint? o_O

Hey

Apology for the long delay. Had a wild run around the app hotfixing bunch of stuff...

As far as I can tell adding this >

QTreeView::branch {
    border-image: none 0;
    image: none 0;
}

Fixed the issue, no idea why :- ) Or what does the 0 at the end do...

But it works :D - unless it breaks something else that I dont know about yet :D

In fact, it's the QTreeView::drawBranch that handles that.
