[Interest] Windows application's main window does not have standard Windows' main-window's features

[Suresh Govindachar]

Hello,

Currently, the main window of an application written in QT on and for 64 
bit Windows 7 does not have the usual Windows title bar -- I mean the 
bar that has the "minimize (_)", "maximize ([])", and "kill (X)" icons 
at the right.  Also, hitting "Alt-spacebar" does not result in the 
Windows standard drop-down menu in the upper left (the menu with items 
Restore, Move. Size, Minimize, Maximize, Close). And right- or left- 
clicking in the upper horizontal area of the application's main window 
does nothing.

I have access to the QT source code of the application.

Question:  What needs to be modified in the code to give this 
application the standard Windows' main-window's feature?

Thanks.
