Title: How to get the caret-position systemwide
function GetCaretPosition(var APoint: TPoint): Boolean;
var w: HWND;
aID, mID: DWORD;
begin
Result:= False;
w:= GetForegroundWindow;
if w 0 then
begin
aID:= GetWindowThreadProcessId(w, nil);
mID:= GetCurrentThreadid;
if aID mID then
begin
if AttachThreadInput(mID, aID, True) then
begin
w:= GetFocus;
if w 0 then
begin
Result:= GetCaretPos(APoint);
Windows.ClientToScreen(w, APoint);
end;
AttachThreadInput(mID, aID, False);
end;
end;
end;
end;
Usage Examples:
set cursor to active caret position
procedure TForm1.Timer1Timer(Sender: TObject);
var
Pt: TPoint;
begin
if GetCaretPosition(Pt) then
begin
ListBox1.Items.Add(Format('Caret position is %d %d', [Pt.x, Pt.y]));
SetCursorPos(Pt.X, Pt.Y);
end;
end;
