My problem was to generate the correct X and Y for the Popup Method. Really, i remember in an other application i saw i must give the X,Y for the left-up point and it's not sure they are the same as pressing-point-mouse. But now, i'm seeing i used the same and it's correctly working; i mean the popup is auto-moving to stay inside the screen. Maybe i wrongly remember about my old application; i think maybe at that time i had the problem to push the popop inside a control and not inside the screen. ----- Original Message ----- From: "Rob Kennedy" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, April 13, 2005 10:08 AM Subject: Re: [delphi-en] Delay popup > > Mauro Russo wrote: > > i'd like to popup the popupmenu AFTER having > > OnMouseDown event. > > Good.
