|
|
// Purpose: virtual base class for wrapping Windows' dialog functionality
|
||
|
|
//
|
||
|
|
// Interface: ShowDialog -- analagous to the Windows DialogBox function
|
||
|
|
// DialogProc -- pure virtual DialogProc for the dialog box
|
||
|
|
// ~CHlprDialog -- destructor

|
||
|
|
// Notes: This class allows a dialog box 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 DialogProc, giving it a "this"
|
||
|
|
// pointer and allowing it to have direct access to all of its
|
||
|
|
// private members.
