cp说BS_AUTORADIOBUTTON 只能用在对话框上?
windows 程序设计 9.1.6 节，page:294
说这个风格这能用在对话框
我提供一个反例：用在窗口上的。
而且我把风格改成: BS_RADIOBUTTON 竟然不能选中了。
怎么回事?
struct
{
int iStyle ;
TCHAR * szText ;
}
button[] =
{
BS_GROUPBOX, TEXT ("性别选择"),
BS_AUTORADIOBUTTON, TEXT ("男"),
BS_AUTORADIOBUTTON, TEXT ("女")
} ;
switch (message)
{
case WM_CREATE :
cxChar = LOWORD (GetDialogBaseUnits ()) ;
cyChar = HIWORD (GetDialogBaseUnits ()) ;
hwndButton[0] = CreateWindow ( TEXT("button"),
button[0].szText,
WS_CHILD | WS_VISIBLE | button[0].iStyle,
0,0,
100,200,
hwnd, (HMENU) 1000,
((LPCREATESTRUCT) lParam)->hInstance, NULL) ;
hwndButton[1] = CreateWindow ( TEXT("button"),
button[1].szText,
WS_CHILD | WS_VISIBLE | button[1].iStyle,
0,20,
60,60,
hwndButton[0], (HMENU) 1001,
((LPCREATESTRUCT) lParam)->hInstance, NULL) ;
hwndButton[2] = CreateWindow ( TEXT("button"),
button[2].szText,
WS_CHILD | WS_VISIBLE | button[2].iStyle,
0,100,
60,60,
hwndButton[0], (HMENU) 1002,
((LPCREATESTRUCT) lParam)->hInstance, NULL) ;
return 0 ;
case WM_COMMAND :
if(LOWORD(wParam)== 1001)
{
SendMessage(hwndButton[1], BM_SETCHECK,1,0);
SendMessage(hwndButton[2], BM_SETCHECK,0,0);
}
else
{
SendMessage(hwndButton[2], BM_SETCHECK,1,0);
SendMessage(hwndButton[1], BM_SETCHECK,0,0);
}
break ;
