Currently, SmartWin++ seems to have incomplete class supporting the Win32 common controls.
I have noticed that there is no class for the List Box control which provides simpler interface than
List View control. Also, there is no class for Tabbed MDI Frame, other frameworks like MFC, WTL,
OWLNext and QT still supports List Box and Tabbed MDI Frame.
With these shortcomings, SmartWin++ is still lagging behind.
