Title: How to obtain a handle to the current Cursor
function GetCursorHandle: HCURSOR;
var
hWindow: HWND;
pt: TPoint;
pIconInfo: TIconInfo;
dwThreadID, dwCurrentThreadID: DWORD;
begin
// Find out which window owns the cursor
// Das zum Mauszeiger zugeh rige Fenster finden
GetCursorPos(pt);
hWindow := WindowFromPoint(pt);
// Get the thread ID for the cursor owner.
// Thread ID des Fensters ermitteln
dwThreadID := GetWindowThreadProcessId(hWindow, nil);
// Get the thread ID for the current thread
// Thread ID f r den aktuellen Thread ermitteln
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
// Wenn der Mauszeiger zu einem anderen Thread geh rt, m ssen wir
// an den anderen Thread anh ngen.
if (dwCurrentThreadID dwThreadID) then
begin
if AttachThreadInput(dwCurrentThreadID, dwThreadID, True) then
begin
// Das Handle des Mauszeigers ermitteln
// Get the handle to the cursor
Result := GetCursor;
AttachThreadInput(dwCurrentThreadID, dwThreadID, False);
end;
end else
begin
Result := GetCursor;
end;
end;

// Informationen ber den Mauszeiger auslesen

// Den Mauszeiger auf die Form zeichnen
