How to set the color of the selected QTreeWidgetItem?
the default selected background color of QTreeWidgetItem is dark-blue, i want to remove this background color and just set a red rectangle for the selected item.
thank you!

Use setdata function and pass the role as background role or text role

BackgroundRole? i think this is not what i need.
cause i just want to change the background color of the Selected WidgetItem. or remove the background color of the Selected WidgetItem

Hi,

I would suggest looking into StyleSheets

with them its easy to accomplish what you want in your case:

the default selected background color of QTreeWidgetItem is dark-blue, i want to remove this background color and just set a red rectangle for the selected item.
thank you !

listWidget->setStyleSheet("QListView::item:selected {background : transparent; border: solid 2px red;}");

background:

ought to be

background-color:

but you should notice that yourself when you read through the docu :)

You can try QBrush as shown here .

 QListView {
        show-decoration-selected: 1;
  }
 QListView::item:selected {
      	border: 1px solid red;
	color: black;
  }
 QListView::item:selected:!active {
      	background: transparent;
  }
 QListView::item:selected:active {
     	background: transparent;
  }
 QListView::item:hover {
        border: 1px solid #FF8888;
  }

If you need more subcontrols, add style. Or vice versa ...

thank you very much
it does work!
but my problem is more complicated.
i have 2 column in a QTreeWidget, the 1st column is text, the 2nd column i set different color by setBackgroundColor for different rows.
and the problem is the default selected item is all blue...
now i just want the selected item has a border, and the 1st column has default white background and black text, the 2nd column still has its own background color which i set for different rows.

You can always disable the default focus of your listwidget

widget->setFocusPolicy(Qt::NoFocus);

And "create your own 'focusHanlder' "

connect(widget, &QListWidget::clicked, [=](QModelIndex index){
//Do Custom Stuff with clicked item
});
