highlighting hovered QListWidget item

Me again.

I have QListWidget where I want to highlight hovered item. The problem is, when I try to do so using CSS, it doesn't work - background color isn't changing on hover. My code:

Code:

---

QStringList files = Settings->recentFiles();
     int numRecentFiles = qMin(files.size(), 5);
     for (int i = 0; i < numRecentFiles; i++)
     {
          listWidget->addItem(new QListWidgetItem(files[i]));
     }
 
     listWidget->setMouseTracking(true);
     listWidget->setStyleSheet("QListWidget::item:hover {background-color:yellow;}");

---

I've also tried to succeed with signal-slot mechanism and I must say, almost did it. The problem is, when cursor leaves the widget, highlight stays at the last hovered element, because I don't know how to use the 'viewport left event'. I would be grateful if someone could provide me some example. (lol, I ended this sentence with semicolon and pushed Ctrl+S).

Thanks in advance

EDIT: Well, right after posting I answered myself the first question. Instead of

Code:

---

listWidget->setStyleSheet("QListWidget::item:hover {background-color:yellow;}");

---

I should write

Code:

---

this->setStyleSheet("QListWidget::item:hover {background-color:yellow;}");

---

but I don't like the effect.

Second question still active though.

this example shows 'background' not 'background-color'

For a single attribute, it is recommended to use specified names.


I managed to achieve the wished effect. Firstly, I was not satisfied with CSS hovering because background wasn't expanding to margins, so I changed margin to padding and now it's ok.

Problem solved (I still don't know how to use viewport, but it's a thing for another story ;))
