// Class: CHlprWindow
|
|
//
|
|
// Purpose: virtual base class for wrapping a window
|
|
//
|
|
// Interface: Create -- analagous to Windows' CreateWindow function
|
|
// WindowProc -- pure virtual WindowProc for the window
|
|
// ~CHlprWindow -- destructor
|
|
// CHlprWindow -- constructor
|
|

// History: 4-12-94 stevebl Created

|
//
|
|
// Notes: This class allows a window to be cleanly wrapped in a
|
|
// c++ class. Specifically, it provides a way for a c++ class
|
|
// to use one of its methods as a WindowProc, giving it a "this"
|
|
// pointer and allowing it to have direct access to all of its
|
|
// private members.
