Differnt Window Style
A program whch lets ypi change window state and style at run time using
API. which otherwise are not possible at run time only possible at design time.
To change window state take less effort from me simply change the windowstate proprety to desired value and make window minimize maximize etc.
But to change window style take much effort as i have to borrow the API
functionality and also to apply some trick to get the desired window style.Like
it is difficult to change window style from fixed toolwindow to sizeable toolwindow and to update the system menu proprely.
the heart of this program is setwindowlong which apply the various windowstyle and getwindowstyle which retrive the windowstyle.
