Description
void QXcbWindow::setWindowFlags(Qt::WindowFlags flags)
{
if (shouldDeferTask(Task::SetWindowFlags))
return;
Qt::WindowType type = static_cast<Qt::WindowType>(int(flags & Qt::WindowType_Mask));
if (type == Qt::ToolTip)
flags |= Qt::WindowStaysOnTopHint | Qt::FramelessWindowHint | Qt::X11BypassWindowManagerHint;
if (type == Qt::Popup)
flags |= Qt::X11BypassWindowManagerHint;
When applying window flags into platform window, some implicit flags are applied, for example, Qt::ToolTip -> Qt::WindowStaysOnTopHint | Qt::FramelessWindowHint | Qt::X11BypassWindowManagerHint and etc on x11/xcb.
It causes the different flags values between QWindow and platform window. Perhaps we should distinguish them correctly.
