一步一步实现扫雷游戏（C语言实现）(四)

首先，我弄个主窗口出来，没有用到MFC，直接调用API函数实现，先看看代码吧：

///
//
//主函数：扫雷
//
///

#include <windows.h>
#include <stdio.h>
#include "DrawMap.h"//见下文
#include "def.h"

int m =10, n =10;
int map[MAX_X][MAX_Y];
int Global_x[MAX_X], Global_y[MAX_Y];


LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;
WINGDIAPI BOOL WINAPI MoveToEx(HDC hdc, int x, int y, LPPOINT lppt);//移动当前画笔的位置
WINGDIAPI BOOL WINAPI LineTo(HDC hdc, int x, int y);//用来画直线的函数
WINGDIAPI HPEN WINAPI CreatePen(int iStyle, int cWidth, COLORREF color); 




int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
 PSTR szCmdLine, int iCmdShow)
{
 init();//初始化数组（地雷分布
int x_position, y_position, x_size, y_size;
 set_position_size(&x_position, &y_position, &x_size, &y_size);

static TCHAR szAppName[] = TEXT ("MainWin") ;
 HWND hwnd ;
 MSG msg ;
 WNDCLASS wndclass ;

 wndclass.style = CS_HREDRAW | CS_VREDRAW ;
 wndclass.lpfnWndProc = WndProc ;
 wndclass.cbClsExtra =0 ;
 wndclass.cbWndExtra =0 ;
 wndclass.hInstance = hInstance ;
 wndclass.hIcon = LoadIcon (NULL, IDI_APPLICATION) ;
 wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ;
 wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
 wndclass.lpszMenuName = NULL ;
 wndclass.lpszClassName = szAppName ;

if (!RegisterClass (&wndclass))
 {
 MessageBox (NULL, TEXT ("This program requires Windows NT!"), 
 szAppName, MB_ICONERROR) ;
return0 ;
 }

 hwnd = CreateWindow (szAppName, // window class name
 TEXT ("扫雷游戏——The ClearMines Game"), // window caption
 WS_OVERLAPPED | \
 WS_CAPTION | \

 WS_MINIMIZEBOX, // window style

 ShowWindow (hwnd, iCmdShow) ;
 UpdateWindow (hwnd) ;
while (GetMessage (&msg, NULL, 0, 0))
 {
 TranslateMessage (&msg) ;
 DispatchMessage (&msg) ;
 }
return msg.wParam ;
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
 { 
case WM_PAINT:
 paint_map(hwnd); //自定义的画图函数
return0;

case WM_LBUTTONDOWN: //单击鼠标
int x=LOWORD(lParam);//x，y为鼠标当前的位置坐标
int y=HIWORD(lParam);
 left_key(hwnd, x, y);//自定义的响应鼠标左键的函数
break;

case WM_DESTROY:
 PostQuitMessage (0) ;
return0 ;
 }
return DefWindowProc (hwnd, message, wParam, lParam) ;
}

现在，看看DrawMap.h文件的一些自定义函数的声明：

#include <windows.h>
#include <stdio.h>
#include "NumMines.h"//这个文件就是前两篇随笔中的那个后台实现算法的，等下也放上来

//全局变量
externint map[MAX_X][MAX_Y];
externint m, n;
externint Global_x[MAX_X], Global_y[MAX_Y];

//自定义函数
void paint_map(HWND hwnd);//又看到它了，那就看代码吧
BOOL DrawGrid(HDC hdc, int x1, int y1, int x2, int y2);//这个函数是实现在上面函数的
//设置窗口位置和大小
void set_position_size(int* p_x_position, int* p_y_position, int* p_x_size, int* p_y_size);
void left_key(HWND hwnd, int x, int y);
void DrawRec(HWND hwnd, HDC hdc, int i, int j);
RECT rectRec(HWND hwnd, int x, int y);//x,y为小矩形左上角的坐标

void paint_map(HWND hwnd);//又看到它了，那就看代码吧

//DrawMap.cpp


//
//画图
//

void paint_map(HWND hwnd)
{
 HDC hdc ;

int x1,y1,x2,y2;
int x_position, y_position, x_size, y_size;

int frame_width = GetSystemMetrics(SM_CXSIZEFRAME); //边框宽度
int caption_width = GetSystemMetrics(SM_CYCAPTION); //标题栏宽度

 x1 = caption_width;

 hdc = BeginPaint (hwnd, &ps) ;
