[Dialog] 시스템 색상 가져오기

GetSysColor 함수를 실행하면 시스템에 설정된 색상값을 가져올 수 있다. 아래의 예제는 버튼 색상을 RGB 로 가져오는 코드이다. 버튼 색상과 대화상자 색상이 같다고 생각하여서 대화상자 색상을 가져오는 함수를 제작한 경우이다.

 

COLORREF GetDialogBkColor()
{
 return GetSysColor( COLOR_BTNFACE );
}

This function retrieves the current color of the specified display element. Display elements are the parts of a window and the Windows display that appear on the system display screen.

DWORD GetSysColor(
  int nIndex
); 

Parameters

nIndex

Specifies the display element whose color is to be retrieved. This parameter must be one of the following values.

Value	Description
COLOR_3DDKSHADOW	Dark shadow for three-dimensional display elements.
COLOR_3DFACE, COLOR_BTNFACE	Face color for three-dimensional display elements.
COLOR_3DHILIGHT, COLOR_3DHIGHLIGHT, COLOR_BTNHILIGHT, COLOR_BTNHIGHLIGHT	Highlight color for three-dimensional display elements (for edges facing the light source).
COLOR_3DLIGHT	Light color for three-dimensional display elements (for edges facing the light source).
COLOR_3DSHADOW, COLOR_BTNSHADOW	Shadow color for three-dimensional display elements (for edges facing away from the light source).
COLOR_ACTIVEBORDER	Active window border.
COLOR_ACTIVECAPTION	Active window title bar.
COLOR_APPWORKSPACE	Background color of multiple document interface (MDI) applications.
COLOR_BACKGROUND, COLOR_DESKTOP	Desktop.
COLOR_BTNTEXT	Text on push buttons.
COLOR_CAPTIONTEXT	Text in caption, size box, and scroll bar arrow box.
COLOR_GRAYTEXT	Grayed (disabled) text. This color is set to 0 if the current display driver does not support a solid gray color.
COLOR_HIGHLIGHT	Item(s) selected in a control.
COLOR_HIGHLIGHTTEXT	Text of item(s) selected in a control.
COLOR_INACTIVEBORDER	Inactive window border.
COLOR_INACTIVECAPTION	Inactive window caption.

Return Values

The red, green, blue (RGB) color value that determines the color of the specified element indicates success. Zero indicates failure. To get extended error information, call GetLastError.

Remarks

Windows CE 1.0 and 1.01 only support a 2-bit gray scale palette, so GetSysColor returns a palette index rather than an RGB value. Microsoft® Windows® CE graphic display interface (GDI) functions that accept a COLORREF structure can use either a palette index or an RGB value. However, if the application attempts to interpret the color value, be aware of this difference.

Windows CE 2.0 supports 2 bits per pixel (2-bpp), 4 bits per pixel (4-bpp), and 8 bits per pixel (8-bpp) color devices, and can logically support 32 bits per pixel device independent bitmaps (DIBs). In Windows CE 2.0, GetSysColor returns an RGB value.

System colors for monochrome displays are usually interpreted as shades of gray.
