Qt Designer StyleSheet. Как поменять обводку выбранного элемента из QComboBox

Question

Этот код меняет background объектов в combobox при наведении

QComboBox QListView {
selection-background-color: rgb(255, 255, 255); 
 }

test.ui

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>MainWindow</class>
 <widget class="QMainWindow" name="MainWindow">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>800</width>
    <height>600</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>MainWindow</string>
  </property>
  <property name="styleSheet">
   <string notr="true">

    /* вот этот код работает */


QComboBox QListView {
      background-color:rgb(52, 58, 64);
    selection-background-color:white;
    
 }
/* а вот этот нет  */
QComboBox QListView::item:hover{
border:1px;
border-color: rgb(170, 85, 127);

}</string>

Попробуйте так:

QComboBox {
    font: 18pt Fira Sans Condensed;     
    background-color: #2e2e2e;
    border-top: 0px solid #3e3e3e;
    border-left: 0px solid #3e3e3e;
    border-right: 0px solid #3e3e3e;
    border-bottom: 2px solid #3e3e3e;
    padding: 5%;
    max-height: 30px;
    min-width: 140px;
    color: white;
    selection-background-color: #5e5e5e;
}

QComboBox::drop-down {
    border: none;
}

QComboBox::down-arrow {
    image: url(down-arrow.png);
    width: 25px;
    height: 25px;
    border-width: 0px;
    padding-right: 10px;
}

QComboBox::down-arrow:pressed {
    position: relative;
    top: 1px; left: 1px;
}

QComboBox QListView {
    background-color: #2e2e2e;
    
/*  outline: 0;                    попробуйте так    */
    outline: 2px solid red;     /*    или так        */
    
    color: white;
    selection-background-color: #5e5e5e;
    padding: 5%;    
}
