great: if (sender = nil)then begin end;
that solves the problem. I like it. On the same idea, I usually wtite: ... myprocedure; var mystring : string; begin ... str(Myreal,mystring); ... but I get the warning: "variable "mystring" does not seem to be initialized" What is it that I am doing wrong? The program works of course, but I want to know the best way to do it. thanks Alain On Wed, 2006-04-26 at 03:45 +0000, Tony Pelton wrote: > On 4/26/06, Alain Michaud <[EMAIL PROTECTED]> wrote: > > Hi, > > > > what does the following compiler message means? > > Hint: parameter "Sender" not used > > this gets discussed from time to time. > > widget event protos require the sender param, but often, the > implementation doesn't use it, so you end up with an "unused" > parameter, which the compiler warns about. > > > Is there something that I can do to improve my source code apart from > > just ignoring the message? > > ignoring it is one option. > > you could also "use" it, the parameter that is, using a no-op to make > the compiler think it is being used. > > there are some suggested variations on this, such as "if(Sender := > nil)" as one of them. > > i think i remember the FPC people talking about making this an > optional hint in the compiler at some point as well. > > maybe for 2.1.1 or something. > > > > > Alain > > Tony > > -- > X-SA user ? 0.5.1 is out ! > XData 0.1 for X-SA is out ! > http://x-plane.dsrts.com > http://games.groups.yahoo.com/group/x-plane-foo/ _________________________________________________________________ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
