[Lazarus] Example of TObjectList sorting
Hi All, I have a TObjectList that contains many objects that have a property called "Position" which is an integer. Could somebody show me an example of the code that I will need to create that will sort all of my Objects within the TObjectList so that they are in position order e.g. 1,2,3,4,5 and so on?

Nothing that the alleged sender can do about it if so. Nuking their account seems a little harsh.

For example: List.Sort(@CompareByPositionPtr); function CompareByPosition(A, B: TMyObject): Integer; inline; begin if A.Position < B.Position then Result := -1 else if A.Position > B.Position then Result := 1 else Result := 0; end; function CompareByPositionPtr(A, B: Pointer): Integer; begin Result := CompareByPosition(TMyObject(A), TMyObject(B)); end; This kind of question is better suited on the forum I think Denis -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Missing components in Lazarus 1.6 DEB
Package "lazarus-1.6" and its sub-packages are missing many of Lazarus 1.6 source files. Reported to Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=823706 Beware when installing from Debian packaged repositories.

Not everybody likes web based forums (I don't). Granted the question related more to the RTL that Lazarus or LCL, so if anything, it could have been posted in the fpc-users mailing list. But you were kind enough to answer anyway. ;-) Regards, Graeme -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Hence, I think this question/answer would reach more end users while being on the forum, instead of on a mailing list.

Lets agree to disagree. ;-) ps: The mailing lists are also searched and indexed by search engines - thanks to services like Nabble and many others. But then again, my email client does just fine searching on its own (and can do it offline). http://free-pascal-lazarus.989080.n3.nabble.com/ http://free-pascal-general.1045716.n5.nabble.com/ Regards, Graeme -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] does dbGrid's AutoSizeColumns method need to also be called in form's OnResize event?
Or is it sufficient to just include this in form's OnCreate or OnShow event? with myDBGrid beginif not (dgautosizecolumns in options) then options := options + [dgautosizecolumns]; AutoSizeColumns; end; Thanks.
