Q: What is an overlapped window?
A: An overlapped window is a top-level window that has a caption (title bar), border and client area.
It is created by specifying WS_OVERLAPPED style in CreateWindow or CreateWindowEx function.
- overlapped windows are generally used as application's main window;
- WS_OVERLAPPED constant is defined in winuser.h and has a value of 0 (zero);
- in practice is used the composite style WS_OVERLAPPEDWINDOW instead of WS_OVERLAPPED;
this adds sizing border, system menu, and minimize and maximize buttons.
Code:#define WS_OVERLAPPEDWINDOW (WS_OVERLAPPED | \ WS_CAPTION | \ WS_SYSMENU | \ WS_THICKFRAME | \ WS_MINIMIZEBOX | \ WS_MAXIMIZEBOX)
