It is possible to make a window unactivable and unfocusable when clicking on it by using Windows flags (#include <qt_windows.h>). The following has to be used after the window is created and shown:

HWND winHandle = (HWND)winId();
ShowWindow(winHandle, SW_HIDE);
SetWindowLong(winHandle, GWL_EXSTYLE, GetWindowLong(winHandle, GWL_EXSTYLE)
    | WS_EX_NOACTIVATE | WS_EX_APPWINDOW);
ShowWindow(winHandle, SW_SHOW);

I don't know about QDialog, I'm using just a QWidget for similar purpose (displaying a Windows 8 style notification).

Try setting:

dialog->setFocusPolicy(Qt::NoFocus);
dialog->setAttribute(Qt::WA_ShowWithoutActivating);

maybe you'll have to set focus policy on all children.
