WinAPI: GetSystemMetrics - 获取系统度量等数值信息
声明:
GetSystemMetrics( nIndex: Integer {参数, 详见下表}): Integer;
举例 - 获取屏幕分辨率:
var cx,cy: Integer;begin {通过 GetSystemMetrics 函数获取屏幕分辨率} cx := GetSystemMetrics(SM_CXSCREEN); cy := GetSystemMetrics(SM_CYSCREEN); ShowMessageFmt('Width:%d; Height:%d', [cx,cy]); {通过 Screen 对象获取屏幕分辨率} cx := Screen.Width; cy := Screen.Height; ShowMessageFmt('Width:%d; Height:%d', [cx,cy]);end;
可选参数:
SM_CXSCREEN = 0;SM_CYSCREEN = 1;SM_CXVSCROLL = 2;SM_CYHSCROLL = 3;SM_CYCAPTION = 4;SM_CXBORDER = 5;SM_CYBORDER = 6;SM_CXDLGFRAME = 7;SM_CYDLGFRAME = 8;SM_CYVTHUMB = 9;SM_CXHTHUMB = 10;SM_CXICON = 11;SM_CYICON = 12;SM_CXCURSOR = 13;SM_CYCURSOR = 14;SM_CYMENU = 15;SM_CXFULLSCREEN = $10;SM_CYFULLSCREEN = 17;SM_CYKANJIWINDOW = 18;SM_MOUSEPRESENT = 19;SM_CYVSCROLL = 20;SM_CXHSCROLL = 21;SM_DEBUG = 22;SM_SWAPBUTTON = 23;SM_RESERVED1 = 24;SM_RESERVED2 = 25;SM_RESERVED3 = 26;SM_RESERVED4 = 27;SM_CXMIN = 28;SM_CYMIN = 29;SM_CXSIZE = 30;SM_CYSIZE = 31;SM_CXFRAME = $20;SM_CYFRAME = 33;SM_CXMINTRACK = 34;SM_CYMINTRACK = 35;SM_CXDOUBLECLK = 36;SM_CYDOUBLECLK = 37;SM_CXICONSPACING = 38;SM_CYICONSPACING = 39;SM_MENUDROPALIGNMENT = 40;SM_PENWINDOWS = 41;SM_DBCSENABLED = 42;SM_CMOUSEBUTTONS = 43;SM_SECURE = 44;SM_CXEDGE = 45;SM_CYEDGE = 46;SM_CXMINSPACING = 47;SM_CYMINSPACING = 48;SM_CXSMICON = 49;SM_CYSMICON = 50;SM_CYSMCAPTION = 51;SM_CXSMSIZE = 52;SM_CYSMSIZE = 53;SM_CXMENUSIZE = 54;SM_CYMENUSIZE = 55;SM_ARRANGE = 56;SM_CXMINIMIZED = 57;SM_CYMINIMIZED = 58;SM_CXMAXTRACK = 59;SM_CYMAXTRACK = 60;SM_CXMAXIMIZED = 61;SM_CYMAXIMIZED = 62;SM_NETWORK = 63;SM_CLEANBOOT = 67;SM_CXDRAG = 68;SM_CYDRAG = 69;SM_SHOWSOUNDS = 70;SM_CXMENUCHECK = 71;SM_CYMENUCHECK = 72;SM_SLOWMACHINE = 73;SM_MIDEASTENABLED = 74;SM_MOUSEWHEELPRESENT = 75;SM_CMETRICS = 76;SM_XVIRTUALSCREEN = 76;SM_YVIRTUALSCREEN = 77;SM_CXVIRTUALSCREEN = 78;SM_CYVIRTUALSCREEN = 79;SM_CMONITORS = 80;SM_SAMEDISPLAYFORMAT = 81;SM_IMMENABLED = 82;SM_CXFOCUSBORDER = 83;SM_CYFOCUSBORDER = 84;SM_REMOTESESSION = $1000;
