Adds support for setting special application windows styles. This includes for example the window's transparency, its icons and allowed operations. By default, VisualWorks supports only basic setting for controlling the look and feel of the application's windows.

The new window operations are found in Smalltalk.Graphics.Window. The actual implementation for changing the style is OS specific and is therefore delegated to subclasses of Smalltalk.OS.OSSystemSupport. See this class for the methods that needs be overridden to support the operations on various platforms.

Currently, only Windows is supported. Unsupported platforms will simply ignore the requests to change the style.

View comments on methods extended on Smalltalk.Graphics.Window for examples of use.

To change the style, the "SetWindowLong Function" is used on Windows platform: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windowclasses/windowclassreference/windowclassfunctions/setwindowlong.asp

Parts of this package are based on the work in the TransparentWindows package found in the Cincom Public Store Database.

Note that this package cannot be loaded together with package TransparentWindows.
