[SOLVED]QTreeWidget setStyleSheet problem

[tony_tang]

I want to set the selected QTreeWidgetItem to a custom color, using the code below:
setStyleSheet("QTreeWidget::item::selected{background-color: rgb(50, 50, 50)}");
but it does not work very well: there is some other color on the left part of the QTreeWidgetItem.
Is there any way to solve this?

Hi

A QTreeWidget will show an arrow for items with children. to the left.
Is it that area you area talking about ?

Its not considered part of the item and will have the color for
background-color for the whole TreeWidget.

If you do not need a tree view, then maybe just use a listwidget where the item
will take up all row. ?

@mrjj Yes, it is the area to show an arrow for items with children.

@mrjj It is used to show the tree of scene, so I have to use the QTreeVidget.

@tony_tang
That area can be styled with QTreeView::branch
have a look at

@mrjj
OK, I take a try, thank you very much.

I solved the problem using this method:

QPalette pal = palette();
pal.setColor(QPalette::ColorRole::Highlight, QColor(50, 50, 50));
setPalette(pal);
