NONCLIENTMETRICSW structure (winuser.h)

  • Article

Contains the scalable metrics associated with the nonclient area of a nonminimized window. This structure is used by the SPI_GETNONCLIENTMETRICS and SPI_SETNONCLIENTMETRICS actions of the SystemParametersInfo function.

Syntax

typedef struct tagNONCLIENTMETRICSW {
  UINT     cbSize;
  int      iBorderWidth;
  int      iScrollWidth;
  int      iScrollHeight;
  int      iCaptionWidth;
  int      iCaptionHeight;
  LOGFONTW lfCaptionFont;
  int      iSmCaptionWidth;
  int      iSmCaptionHeight;
  LOGFONTW lfSmCaptionFont;
  int      iMenuWidth;
  int      iMenuHeight;
  LOGFONTW lfMenuFont;
  LOGFONTW lfStatusFont;
  LOGFONTW lfMessageFont;
  int      iPaddedBorderWidth;
} NONCLIENTMETRICSW, *PNONCLIENTMETRICSW, *LPNONCLIENTMETRICSW;

Members

cbSize

The size of the structure, in bytes. The caller must set this to sizeof(NONCLIENTMETRICS). For information about application compatibility, see Remarks.

iBorderWidth

The thickness of the sizing border, in pixels. The default is 1 pixel.

iScrollWidth

The width of a standard vertical scroll bar, in pixels.

iScrollHeight

The height of a standard horizontal scroll bar, in pixels.

iCaptionWidth

The width of caption buttons, in pixels.

iCaptionHeight

The height of caption buttons, in pixels.

lfCaptionFont

A LOGFONT structure that contains information about the caption font.

iSmCaptionWidth

The width of small caption buttons, in pixels.

iSmCaptionHeight

The height of small captions, in pixels.

lfSmCaptionFont

A LOGFONT structure that contains information about the small caption font.

iMenuWidth

The width of menu-bar buttons, in pixels.

iMenuHeight

The height of a menu bar, in pixels.

lfMenuFont

A LOGFONT structure that contains information about the font used in menu bars.

lfStatusFont

A LOGFONT structure that contains information about the font used in status bars and tooltips.

lfMessageFont

A LOGFONT structure that contains information about the font used in message boxes.

iPaddedBorderWidth

The thickness of the padded border, in pixels. The default value is 4 pixels. The iPaddedBorderWidth and iBorderWidth members are combined for both resizable and nonresizable windows in the Windows Aero desktop experience. To compile an application that uses this member, define _WIN32_WINNT as 0x0600 or later. For more information, see Remarks.

Windows Server 2003 and Windows XP/2000:  This member is not supported.

Remarks

If the iPaddedBorderWidth member of the NONCLIENTMETRICS structure is present, this structure is 4 bytes larger than for an application that is compiled with _WIN32_WINNT less than or equal to 0x0502. For more information about conditional compilation, see Using the Windows Headers.

Windows Server 2003 and Windows XP/2000:  If an application that is compiled for Windows Server 2008 or Windows Vista must also run on Windows Server 2003 or Windows XP/2000, use the GetVersionEx function to check the operating system version at run time and, if the application is running on Windows Server 2003 or Windows XP/2000, subtract the size of the iPaddedBorderWidth member from the cbSize member of the NONCLIENTMETRICS structure before calling the SystemParametersInfo function.

Note

The winuser.h header defines NONCLIENTMETRICS as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.

Minimum supported client Windows 2000 Professional [desktop apps only]
