API之子窗口创建 (转)

子窗口的创建非常非常重要

步骤：1、新建窗口类，在窗口类中指名对应的自定义的窗口过程。窗口类类名要唯一，它

是各窗口类相互区别的标识。注意，类名或为静态变量，或为全局变量，因为程

序随时都用他们。

2、创建窗体时，指定其风格之一为WS_CHILD, 指定其父窗口句柄，得到父窗体实

例句柄，并赋给子窗体。

3、在主窗体的create消息中，创建0尺寸的子窗体，主窗体的size消息中，利用

movewindow函数，重设窗体大小，重置窗体位置。

实例为CTRL002,CTRL003

实例CTRL001单击按钮显示对应文字

子窗口向父窗口发送消息

CreateWindow呼叫使用下面这些参数：

Class name（类别名称）

Window text（窗口文字）

Window style（窗口样式）

x position（x位置）

y position（y位置）

Width（宽度）

Height（高度）

Parent window（父窗口）

Child window ID（子窗口ID）

Instance handle（执行实体句柄

）Extra parameters（附加参数）

TEXT ("button")

button[i].szText

WS_CHILD|WS_VISIBLE|button[i].iStyle

cxChar

cyChar * (1 + 2 * i)

20 * xChar

7 * cyChar / 4

hwnd

(HMENU)i

((LPCREATESTRUCT) lParam) -> hInstance

NULL

说明：从WM_COMMAND区别出单击了哪个按钮。通过子窗口的ID号来区分。每个子窗口在创建时，就已经分配了一个唯一的ID号。ID号包含在WM_COMMAND消息中wParam的低字节位。用LOWORD()宏来获取ID。

“用鼠标单击按钮时，子窗口控制就向其父窗口发送一个WM_COMMAND消息。...捕获WM_COMMAND消息....”

“LOWORD(wParam) 子窗口ID

HIWORD(wParam) 通知码

lParam 子窗口句柄”

实例CTRL002 利用多个静态窗体绘制棋盘

说明：1、窗体类别必需是static类，否则程序不能生成静态窗体

2、利用GetWindowLong得到窗体实例句柄

3、HWND是数值类型，可以定义成数组

4、创建子窗体时，将大小设为0,以便重置

4、利用movewidow(...)函数重置静态子窗体位置
