MINIGUI 中主窗口、控件（即子窗口）的理解
MINIGUI 中大体分为 主窗口、控件（即子窗口），而其他的一些都属于这两类，如对话框属于主窗口，按键等属于控件
对于主窗口、控件的理解，根据以下程序和效果图，更容易明白。
#include <stdio.h>
#include <stdlib.h>
#include <minigui/common.h>
#include <minigui/minigui.h>
#include <minigui/gdi.h>
#include <minigui/window.h>
#include <minigui/control.h>
/*
函数原型：
HWND GUIAPI CreateWindow(class_name, caption, style, id, x, y, w, h, parent, add_data)
*/
