炫彩界面库源码分析---简单的应用程序过程分析
炫彩界面库免费开源后，可以方便使用。它的原理是DirectUI，直接绘制控件并做出相关响应，下面来一一分析。
一个简单的应用程序过程分析: 源码如下
int WINAPI _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
XInitXCGUI(); //界面库初始化
//创建窗口
HWINDOW hWindow=XWnd_CreateWindow(400,200,300,200,L"炫彩界面库 - 窗口");
if(hWindow) //创建成功
XWnd_ShowWindow(hWindow,SW_SHOW); //显示窗口
else
return 0; //创建失败
XRunXCGUI(); //运行
return 0;
}
总体的过程分为四部分。
一.界面库初始化XInitXCGUI
二.创建普通窗口XWnd_CreateWindow
三.显示窗口XWnd_ShowWindow
四.运行消息循环XRunXCGUI
下面开始分析每个部分
一.界面库初始化XInitXCGUI
XInitXCGUI函数内部做了如下工作:
1、注册窗口
2、注册剪切板格式
3、初始化4个临界资源对象
4、创建后台线程
简化后代码
HMODULE hInstance = GetModuleHandle(NULL);
HMODULE hInsIcon = hInstance;
//注册窗口
WNDCLASSEXW wcex = {0};
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = XCGUI_WndProc;
wcex.hInstance = hInstance;
wcex.hIcon = LoadIcon(hInsIcon,MAKEINTRESOURCE(IDI_ICON1));
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcex.lpszMenuName = NULL;
wcex.lpszClassName = XCGUI_CLASS_NAME;
wcex.hIconSm = LoadIcon(hInsIcon,MAKEINTRESOURCE(IDI_SMALL));
::RegisterClassEx(&wcex)
//注册剪切板格式
g_clipborad_HTMLFormat=RegisterClipboardFormat(L"HTML Format");
g_clipbroad_RichEditFormat=RegisterClipboardFormat(L"XCGUI_RichEdit_Format");
Resource_Init(); //资源初始化
GdiplusStartupInput gdiplusStartInput;
GdiplusStartup(&gdiplusToken, &gdiplusStartInput, NULL);//GDI++
if(g_fun_init && FALSE==g_fun_init()) //UI文件解析库XML初始化
{
return FALSE;
}
//初始化临界资源对象

return NULL;
}
//g_fun_create_window函数指针是否存在

//XML文件创建
if(g_fun_create_window && FALSE==g_fun_create_window((HWINDOW)pWindow))
{
return FALSE;
}
}
return (HWINDOW)pWindow;
}函数简化后

//调整窗口

return FALSE;
}1.该函数首先是填充结构体window_内部成员的相关数值
2.调用了系统API窗口窗口CreateWindowExW
3.Resource_AddWindow(hWindow);//往资源管理内添加窗口-----必须添加
4.设置标题栏和边框等
5.注册窗口过程函数、注册非客户区消息、注册窗口标准消息
6.窗口最大化、最小化、关闭按钮
7.调整窗口
三.显示窗口XWnd_ShowWindow
四.运行消息循环XRunXCGUI
void WINAPI XRunXCGUI()
{
MSG msg;
// 主消息循环:
while (true)
{
if(Resource_GetWindowCount()<1)
break;
GetMessage(&msg, NULL, 0, 0);
TranslateMessage(&msg);
DispatchMessage(&msg);
}
XExitProcess();
}XExitProcess 退出函数，处理了一些释放资源
