Question

I want to implement tree widget but it doesn’t have to show the hierarchy line.
Please help on this.

(Hierarchy means the line between parent and child.)

Answer 1

Use QSS styles – assign empty image to lines…

QTreeView::branch
 {
    border-image: none;
    image: url(:/style/blankImage.png);
 }

if lines are still exists after that- create png with one transparent pixel and assign it to TreeView’s branch, i haven’t checked variant with no image at all.
