What about inheritance of forms? lazarus / 10-Designer ---------------------------------------------------------------------- p_evghenii · 2004-08-25 10:52 I tried to inherit one form from another one. I couldn't find a tool in the IDE which allows to inherit forms, so I just typed in the editor   TForm2 = class(TForm1) and in the uses clause I added unit1. TForm1 has a button on the form. In run-time this button appears on Form2 and it does react on events, but I cannot see it in design-time. It is quite inconvenient to inherit forms with multiple controls on them, because you cannot see them in design-mode and you should put new controls on child-forms and every time check their correspondence to overall interface in run-time - it takes too much time. Is there a tool for such inheritance or may be is it planned to make this? ---------------------------------------------------------------------- Marc · 2004-08-25 11:55 Pfeew... It might take some time. Not only the LCL has to support it, also component streaming (as part of the fcl) IMO it is not easy, so I don't expect it soon. ---------------------------------------------------------------------- Anonymous · 2004-09-21 22:03 Visual forms inheritance is very important feature, especially for migrating Delphi projects. It was introduced first by Delphi2 and changed projects development significantly. Lazarus team should think about adding this feature, it shouldn't be very complicated task. ---------------------------------------------------------------------- Anonymous · 2004-11-19 13:03 For me it is also the most important thing of RAD.  For this reason I abandoned to use JBuilder, Eclipse and SharpDevelop :-( ---------------------------------------------------------------------- Anonymous · 2005-05-09 13:12 Quote from: "Anonymous"For me it is also the most important thing of RAD.  For this reason I abandoned to use JBuilder, Eclipse and SharpDevelop :-(Seriously, your view of RAD is very narrow if you find missing a marginal feature only present in few development tools a show-stopper. I've been doing development in Delphi for 5 years and needed the feature only twice. ---------------------------------------------------------------------- matthijs · 2005-05-09 16:48 My opinion is having a implementation of TFrame is of more use then visual inheretance of used forms. And this should now be possible see vincents remark on http://www.lazarus.freepascal.org/mantis/view.php?id=816.
