L_LTEFX_API L_INT L_EfxDrawFrame(hDC, pRect, uFlags, uFrameWidth, crFrame, uInnerWidth, crInner1, crInner2, uOuterWidth, crOuter1, crOuter2)

HDC hDC;	handle to the target device context
RECT *pRect;	pointer to the display rectangle
L_UINT uFlags;	frame style
L_UINT uFrameWidth;	middle band width
COLORREF crFrame;	middle band color
L_UINT uInnerWidth;	inner band width
COLORREF crInner1;	inner band shadow color
COLORREF crInner2;	inner band highlight color
L_UINT uOuterWidth;	outer band width
COLORREF crOuter1;	outer band shadow color
COLORREF crOuter2;	outer band highlight color

Draws a rectangular frame having the specified style, color, and border width into the target device context.

Parameter	Description
hDC	Handle to the target device context.
pRect	Pointer to the display destination rectangle.
uFlags	Frame style. The following are valid values:
	Value	Meaning

	EFX_FRAME_OUTER_INSET	[0x0000] Outer band inset
	EFX_FRAME_OUTER_RAISED	[0x0010] Outer band raised
	EFX_FRAME_ADJUST_RECT	[0x0100] Adjust dimensions of the destination rectangle
uFrameWidth	Middle band width.
crFrame	COLORREF value that specifies the middle band color.
uInnerWidth	Inner band width.
crInner1	COLORREF value that specifies the inner band shadow color.
crInner2	COLORREF value that specifies the inner band highlight color.
uOuterWidth	Outer band width.
crOuter1	COLORREF value that specifies the outer band shadow color.
crOuter2	COLORREF value that specifies the outer band highlight color.

Example

This example shows the minimum requirements for using the L_EfxDrawFrame function to draw a frame with a palette.

L_INT EfxDrawFrameExample(HWND     hWnd,RECT*    pDest) 
{ 
   L_INT nRet; 
   HDC       hdc;                    /* Device context for the current window */ 
   HPALETTE  hSavedPalette = NULL;   /* Temporary copy of the current system palette */ 
   HPALETTE  hOurPalette = NULL;     /* The palette that we will use to paint */ 
   L_INT     nBitsPerPixel; 
   /* Get the device context */ 
   hdc = GetDC (hWnd); 
   /* Check the device to see if we need a palette */ 
   nBitsPerPixel = GetDeviceCaps( hdc, BITSPIXEL ) * GetDeviceCaps ( hdc, PLANES ); 
   if ( nBitsPerPixel <=8 ) 
   { 
      hOurPalette = (HPALETTE)GetStockObject (DEFAULT_PALETTE); 
      hSavedPalette = SelectPalette (hdc, hOurPalette, FALSE); 
      /* Realize our palette */ 
      RealizePalette (hdc); 
   } 
   /* Draw the frame */ 
   nRet = L_EfxDrawFrame(hdc,                     /* Device context */ 
   pDest,                   /* Destination rectangle */ 
   EFX_FRAME_OUTER_RAISED,  /* outer band raised */ 
   2,                       /* middle band width*/ 
   RGB ( 255,0,0 ),         /* middle band color */ 
   2,                       /* inner band width*/ 
   RGB ( 100,100,100 ),     /* inner band shadow color */ 
   RGB ( 0,0,0 ),           /* inner band highlight color */ 
   2,                       /* outer band width*/ 
   RGB ( 128,128,128 ),     /* inner band shadow color */ 
   RGB ( 255,255,0 ) );     /* inner band highlight color */ 
   if(nRet != SUCCESS) 
      return nRet; 
   /* Restore the old palette */ 
   if  ( hOurPalette ) 
      SelectPalette (hdc, hSavedPalette, FALSE); 
   /* Release the device context */ 
   ReleaseDC(hWnd, hdc); 
   return SUCCESS; 
}
