你可以开始阅读这个页面：演练：创建Windows桌面应用程序（C ++） [ ^ ]。
You could start reading this page: Walkthrough: Creating Windows Desktop Applications (C++)[^].


参见旧图形（Windows） [ ^ ]。


想想GUI需要什么：





  • GUI包含必须绘制的可见元素。这需要使用依赖于操作系统的图形界面，如GDI和GDI +与Windows。然后设计可见元素并实现绘图功能。
  • GUI通常具有活动元素（例如活动窗口和具有焦点的控件）。因此，您必须实现处理这些状态。
  • GUI必须处理不同类型的用户输入，例如键盘，鼠标或触摸屏。此类设备还有系统相关接口。
  • 在用户输入时，必须执行特定操作。这通常通过某种消息处理和事件处理来实现。
Just think about what a GUI needs:


  • A GUI contains visible elements which must be drawn. This requires using an operating system dependant graphic interface like GDI and GDI+ with Windows. Then design the visible elements and implement the drawing functions.
  • A GUI usually has active elements (e.g. the active window and a control that has the focus). So you must implement handling these states.
  • A GUI must process different kinds of user input like from keyboard, mouse, or touch screen. There are again system dependant interface for such devices.
  • Upon user input specific actions must be performed. This is usually implemented by some kind of message processing and event handling.
