Is there a way to press the right button of the mouse on the wrong words and see the possible correct words?
You could detect the right button click from OnMouseDown, get the word at mouse cursor position and insert from there your code to invoke the Addict spell dialog
procedure TForm4.AdvMemo1MouseDown(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);
var
s: string;
cx,cy: integer;
begin
if (button = mbRight) then
begin
advmemo1.MouseToCursor(x,y,cx,cy);
s := advmemo1.WordAtXY(cx,cy);
// show Addict dialog here
end;
