API(乱七八糟)
windows程序設(shè)計
API：
創(chuàng)建窗口：CreateWindow()
函數(shù)功能：該函數(shù)創(chuàng)建一個重疊式窗口、彈出式窗口或子窗口。它指定窗口類，窗口標(biāo)題，窗口風(fēng)格，以及窗口的初始位置及大小（可選的）。該函數(shù)也指定該窗口的父窗口或所屬窗口（如果存在的話），及窗口的菜單。若要使用除CreateWindow函數(shù)支持的風(fēng)格外的擴展風(fēng)格，則使用CreateWindowEx函數(shù)代替CreateWindow函數(shù)。
函數(shù)原型：HWND CreateWindow(LPCTSTR lpClassName,LPCTSTR lpWindowName,DWORD dwStyle,int x,int y,int nWidth，int nHeight，HWND hWndParent,HMENU hMenu，HANDLE hlnstance，LPVOID lpParam);
hwnd = CreateWindow (szAppName, // window class name
TEXT ("The Hello Program"), // window caption
WS_OVERLAPPED | \
WS_CAPTION | \
WS_SYSMENU | \
WS_MINIMIZEBOX, // window style
x_position, // initial x position
y_position, // initial y position
x_size, // initial x size
y_size, // initial y size
NULL, // parent window handle
NULL, // window menu handle
hInstance, // program instance handle
NULL) ; // creation parameters
ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;
API：讀取屏幕大小(不包括任務(wù)欄)
int width = GetSystemMetrics(SM_CXFULLSCREEN;
int heigh = GetSystemMetrics(SM_CYFULLSCREEN);
//設(shè)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)
{
int width = GetSystemMetrics(SM_CXFULLSCREEN);//讀取屏幕大小
int heigh = GetSystemMetrics(SM_CYFULLSCREEN);
* p_x_position = (int)width/3;
* p_y_position =(int)heigh/5;
* p_x_size = (int)width/3;
* p_y_size = (int)width/3;
}
API:GetSystemMetrics()
int frame_width = GetSystemMetrics(SM_CXSIZEFRAME); //邊框?qū)挾?/span>
int caption_width = GetSystemMetrics(SM_CYCAPTION); //標(biāo)題欄寬度
int menu_high = GetSystemMetrics(SM_CYMENU); //菜單高度
畫矩形：Rectangle(hdc, x1, y1, x2, y2);
畫直線：
MoveToEx是用來移動當(dāng)前畫筆的位置，LineTo是用來畫直線的函數(shù)，其實在計算機圖形里的直線顯示是使用光柵圖形學(xué)里的原理。
函數(shù)MoveToEx和LineTo聲明如下：
WINGDIAPI BOOL WINAPI MoveToEx( __in HDC hdc, __in int x, __in int y, __out_opt LPPOINT lppt);
hdc是當(dāng)前設(shè)備的句柄。
x是X軸的位置，水平方向，一般原點是在屏幕左上角的位置。
y是Y軸的位置，垂直方向。
lppt是移動前的坐標(biāo)位置。
WINGDIAPI BOOL WINAPI LineTo( __in HDC hdc, __in int x, __in int y);
hdc是當(dāng)前設(shè)備的句柄。
x是X軸的位置，水平方向，一般原點是在屏幕左上角的位置。
y是Y軸的位置，垂直方向。
WINGDIAPI HPEN WINAPI CreatePen( __in int iStyle, __in int cWidth, __in
COLORREF color);
iStyle 是畫筆的類型，比如是實線，還是虛線等等。
cWidth 是線的寬度。
color 是線的顏色。
