Thread: Button Design

Hi,

I'm having some trouble trying to create button design. I can't seem to put the buttons into a group box.

Here's an example of what I mean:

Here's my code:

Code:

struct
{
     int     iStyle ;
     TCHAR * szText ;
}
button[] =
{
	 BS_GROUPBOX,						TEXT ("Colours"),
	 WS_CHILD | BS_AUTORADIOBUTTON,	    TEXT ("Red"),
	 WS_CHILD | BS_AUTORADIOBUTTON,	    TEXT ("Green"),
	 WS_CHILD | BS_AUTORADIOBUTTON,	    TEXT ("Blue"),
} ;

#define NUM (sizeof button / sizeof button[0])


LRESULT CALLBACK HelloWndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
	PAINTSTRUCT ps ;
	static RECT rect;
	static int   cxChar, cyChar ;
	HDC	hdc;
	static COLORREF colours[3]={RGB(255,0,0),RGB(0,255,0),RGB(0,0,255)};
	static TCHAR* colour[3] = {TEXT("Red"), TEXT("Green"), TEXT("Blue")};
	static HWND  hwndButton[NUM] ;
	int i;

	switch (message)
	{
		case WM_CREATE:
			cxChar = LOWORD (GetDialogBaseUnits ()) ;
            cyChar = HIWORD (GetDialogBaseUnits ()) ;
			for (i = 0 ; i < NUM ; i++)
               hwndButton[i] = CreateWindow ( TEXT("button"), 
                                   button[i].szText,
                                   WS_CHILD | WS_VISIBLE | button[i].iStyle,
                                   cxChar, cyChar * (1 + 2 * i),
                                   20 * cxChar, 7 * cyChar / 4,
                                   hwnd, (HMENU) i,
                                   ((LPCREATESTRUCT) lParam)->hInstance, NULL) ;
			return 0;

		case WM_PAINT :
			InvalidateRect (hwnd, &rect, TRUE) ;
			hdc = BeginPaint (hwnd, &ps) ;
            SelectObject (hdc, GetStockObject (SYSTEM_FIXED_FONT)) ;
            SetBkMode (hdc, TRANSPARENT) ;
			EndPaint (hwnd, &ps) ;
			return 0;
		case WM_DESTROY:
			PostQuitMessage(0);
			return 0;
	}

	return DefWindowProc(hwnd, message, wParam, lParam);
}

>> (HMENU) i

This might not be correct, but I think that this is one problem. You're assigning the button a menu that, as far as I know, doesn't exist, which I'm sure is a problem.

I'll try that

I'm not sure if that's the only problem, but that should certainly have something to do with it.
