надо его вручную дорисовать
Code: |
procedure GetScreenImage(bmp: TBitmap); var CI: TCursorInfo; Icon: TIcon; II: TIconInfo; r: TRect; begin bmp.Width:= Screen.Width; bmp.Height:= Screen.Height; BitBlt(bmp.Canvas.Handle,0,0,Screen.Width,Screen.Height, GetDC(GetDesktopWindow),0,0,SRCCopy); //дорисуем курсор Icon:=TIcon.Create; r:=Rect(0,0,GetSystemMetrics(SM_CXSCREEN),GetSystemMetrics(SM_CYSCREEN)); CI.cbSize:=SizeOf(CI); if (GetCursorInfo(CI)) and (CI.flags=CURSOR_SHOWING) then begin Icon.Handle:=CopyIcon(CI.hCursor); if GetIconInfo(Icon.Handle,II) then bmp.Canvas.Draw(ci.ptScreenPos.x - Integer(II.xHotspot) - r.Left, ci.ptScreenPos.y - Integer(II.yHotspot) - r.Top, Icon); end; end; |

// 1. Get the handle to the current mouse-cursor and its position function GetCursorInfo2: TCursorInfo; var hWindow: HWND; pt: TPoint; pIconInfo: TIconInfo; dwThreadID, dwCurrentThreadID: DWORD; begin Result.hCursor := 0; ZeroMemory(@Result, SizeOf(Result)); // Find out which window owns the cursor if GetCursorPos(pt) then begin Result.ptScreenPos := pt; hWindow := WindowFromPoint(pt); if IsWindow(hWindow) then begin // Get the thread ID for the cursor owner. dwThreadID := GetWindowThreadProcessId(hWindow, nil);
// Get the thread ID for the current thread dwCurrentThreadID := GetCurrentThreadId;
// If the cursor owner is not us then we must attach to // the other thread in so that we can use GetCursor() to // return the correct hCursor if (dwCurrentThreadID <> dwThreadID) then begin if AttachThreadInput(dwCurrentThreadID, dwThreadID, True) then begin // Get the handle to the cursor Result.hCursor := GetCursor; AttachThreadInput(dwCurrentThreadID, dwThreadID, False); end; end else begin Result.hCursor := GetCursor; end; end; end; end;
