QListWidget + setWindowFlags = bad scrollbar

I create a modal gui just to show a list with a QListWidget.
This is the class:

Code:

---

class CShowRolesModalGui : public QDialog
{
	Q_OBJECT
 
	public:
		CShowRolesModalGui(const QStringList& items, QWidget* parent);
 
	private slots:
		void Close () { done(0); }
};

---

and this is the code:

Code:

---

CShowRolesModalGui::CShowRolesModalGui(const QStringList& items, QWidget* parent) : QDialog(parent)
{
	setGeometry(QRect(QPoint(205, 430), QSize(400, 300)));
	setFixedSize(400, 300);
	setStyleSheet(ROLES_WIDGET_STYLE);
	setWindowFlags(Qt::FramelessWindowHint);
 
	QListWidget* listView = new QListWidget(this);
	listView->setGeometry(2, 2, 396, 260);
	listView->setStyleSheet(LIST_SHOW_ROLE_STYLE);
	listView->addItems(items);
 
	QPushButton* btn = new QPushButton(tr("Ok"), this);
	btn->setGeometry(175, 265, 50, 30);
	btn->setStyleSheet(FREQ_MODAL_BTN_STYLE);
	connect(btn, SIGNAL(clicked()), this, SLOT(Close()));
}

If I call the function setWindowFlags (and I have to call it as I don't want a gui with a border), the QListWidget's scrollbar is visible but doesn't work with the mouse buttons, only with the wheel and the keyboard.

How can I solve the problem ? I really need a GUI without a border.
Thanks.

PS: I doesn't work also with:
setWindowFlags(windowFlags() | Qt::FramelessWindowHint);
setWindowFlags(Qt::FramelessWindowHint);
setWindowFlags(Qt::CustomizeWindowHint);
and so on ...

can you attach minimal compilable example which reproduces the problem?

I'd start by using layouts in your program. Next I'd try if removing the style sheet fixes the problem.

Sorry I was in a meeting ...

Ok, I've just tried to remove the stylesheet and it works.
The stylesheet was like this:

Code:

---

#define ROLES_WIDGET_STYLE    \
"color: black;"               \
"font: bold;"                 \
"border: 2px solid black; "   \
"border-radius: 5px; "        \
"padding: 0px; "              \
"background-color: rgb(200, 200, 200);"

Why layouts ? it's only a stupid sub gui that shows only a list.

Ok, found.
If only one of these style is set, the scrollbar doesn't work with the mouse.

border: 2px solid black;
border-radius: 5px;
background-color: rgb(200, 200, 200);


Can understand the border, but the background-color ??? :confused:

Should you try this string:

Code:

---

background-color: #C8C8C8;

---

?

You should probably style the scrollbar's groove as well.
