Overview of this book

It is critical that modern developers have the right tools to build practical, user-friendly, and efficient applications in order to compete in today’s market. Through hands-on guidance, this book illustrates and demonstrates C++ best practices and the Small Windows object-oriented class library to ease your development of interactive Windows applications. Begin with a focus on high level application development using Small Windows. Learn how to build four real-world applications which focus on the general problems faced when developing graphical applications. Get essential troubleshooting guidance on drawing, spreadsheet, and word processing applications.

The reason is simply that we do not need the functionality of the StandardDocument framework or its base class Document. We do not use menus or accelerators, and we do not save or load files:

TetrisWindow.h

class TetrisWindow : public Window { 
  public: 
    TetrisWindow(WindowShow windowShow); 
    ~TetrisWindow(); 

In this application, we ignore the mouse. Instead, we look into keyboard handling. The OnKeyDown method is called when the user presses or releases a key:

    bool OnKeyDown(WORD key, bool shiftPressed,

Similar to the circle application, the OnDraw method is called every time the window's client area needs to be redrawn:

    void OnDraw(Graphics& graphics, DrawMode drawMode) const;
