  • 项目

1/6/2010

This function retrieves the dimensions of Microsoft® Windows® display elements and system configuration settings of a remote Windows Embedded CE–based device. All dimensions retrieved by CeGetSystemMetrics are in pixels.

Syntax

INT CeGetSystemMetrics(
  INT nIndex
);

Parameters

  • nIndex
    [in] Specifies the system metric or configuration setting to retrieve. All SM_CX* values are widths. All SM_CY* values are heights. The following values are defined.

    Value Description

    SM_CMONITORS

    Number of display monitors on the Windows Embedded CE-based device. Supported in Windows Embedded CE versions 4.0 and later.

    SM_CXBORDER

    SM_CYBORDER

    Width and height, in pixels, of a window border. This is equivalent to the SM_CXEDGE value for windows with the 3-D look.

    SM_CXCURSOR

    SM_CYCURSOR

    Width and height, in pixels, of a cursor. The system cannot create cursors of other sizes. This value is only valid for devices that support cursors.

    SM_CXDLGFRAME

    SM_CYDLGFRAME

    Same as SM_CXFIXEDFRAME and SM_CYFIXEDFRAME.

    SM_CXDOUBLECLK

    SM_CYDOUBLECLK

    Width and height, in pixels, of the rectangle around the location of a first click in a double-click sequence. The second click must occur within this rectangle for the system to consider the two clicks a double-click. (The two clicks must also occur within a specified time.)

    SM_CXEDGE, SM_CYEDGE

    Dimensions, in pixels, of a 3-D border. These are the 3-D counterparts of SM_CXBORDER and SM_CYBORDER.

    SM_CXFIXEDFRAME, SM_CYFIXEDFRAME

    Thickness, in pixels, of the frame around the perimeter of a window that has a caption but is not sizable. SM_CXFIXEDFRAME is the width of the horizontal border and SM_CYFIXEDFRAME is the height of the vertical border.

    Same as SM_CXDLGFRAME and SM_CYDLGFRAME.

    SM_CXICON, SM_CYICON

    The default width and height, in pixels, of an icon. The LoadIcon function can load only icons of these dimensions.

    SM_CXICONSPACING, SM_CYICONSPACING

    Dimensions, in pixels, of a grid cell for items in large icon view. Each item fits into a rectangle of this size when arranged. These values are always greater than or equal to SM_CXICON and SM_CYICON.

    SM_CXSCREEN

    SM_CYSCREEN

    Width and height, in pixels, of the screen of the primary display monitor. These are the same values you obtain by calling GetDeviceCaps(hdcPrimaryMonitor, HORZRES/VERTRES).

    SM_CXSMICON

    SM_CYSMICON

    Recommended dimensions, in pixels, of a small icon. Small icons typically appear in window captions and in small icon view.

    SM_CXVIRTUALSCREEN

    SM_CYVIRTUALSCREEN

    Width and height, in pixels, of the virtual screen. The virtual screen is the bounding rectangle of all display monitors. Supported in Windows Embedded CE versions 4.0 and later.

    SM_CXVSCROLL

    SM_CYVSCROLL

    Width, in pixels, of a vertical scroll bar; and height, in pixels, of the arrow bitmap on a vertical scroll bar.

    SM_CYCAPTION

    Height, in pixels, of a normal caption area.

    SM_CYMENU

    Height, in pixels, of a single-line menu bar.

    SM_DEBUG

    TRUE or nonzero if the debugging version of USER.EXE is installed; FALSE or zero otherwise.

    SM_MOUSEPRESENT

    TRUE or nonzero if a mouse is installed; FALSE or zero otherwise.

    SM_MOUSEWHEELPRESENT

    TRUE or nonzero if a mouse with a wheel is installed; FALSE or zero otherwise.

    SM_SAMEDISPLAYFORMAT

    TRUE if all the display monitors have the same color format, FALSE otherwise. Supported in Windows Embedded CE versions 4.0 and later.

    SM_XVIRTUALSCREEN

    SM_YVIRTUALSCREEN

    Coordinates for the left side and the top of the virtual screen. The virtual screen is the bounding rectangle of all display monitors. Supported in Windows Embedded CE versions 4.0 and later.

Return Value

The requested system metric or configuration setting indicates success. Zero indicates failure. The CeGetLastError function does not provide extended error information.

Remarks

Windows Embedded CE Remarks

System metrics may vary from display to display.

If the Windows Embedded CE–based device you are targeting supports a mouse cursor, you can use the SM_CXCURSOR or SM_CYCURSOR values in the nIndex parameter.

Windows Embedded CE versions that support mouse cursors include the Iconcurs and Mcursor components rather than the Icon and Cursor components.

General Remarks

System metrics may vary from display to display.

The SM_ARRANGE setting specifies how the system arranges minimized windows, and consists of a starting position and a direction. The starting position can be one of the following values.

Value Description

ARW_BOTTOMLEFT

Start at the lower-left corner of the screen (default position).

ARW_BOTTOMRIGHT

Start at the lower-right corner of the screen. Equivalent to ARW_STARTRIGHT.

ARW_HIDE

Hide minimized windows by moving them off the visible area of the screen.

ARW_TOPLEFT

Start at the upper-left corner of the screen. Equivalent to ARV_STARTTOP.

ARW_TOPRIGHT

Start at the upper-right corner of the screen. Equivalent to ARW_STARTTOP | SRW_STARTRIGHT.

The direction in which to arrange can be one of the following values.

Value Description

ARW_DOWN

Arrange vertically, top to bottom.

ARW_LEFT

Arrange horizontally, left to right.

ARW_RIGHT

Arrange horizontally, right to left.

ARW_UP

Arrange vertically, bottom to top.
