[lazarus] Freeing runtime components.
Sorry for such a simple question but I'm just getting back to programming (as a hobby). Haven't done much since TP5. Anyway, if I create a component eg TPanel during runtime and set it's owner property to a form, do I have to write code to free the panel or is there already code in the forms destructor to free owned classes? _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Editor Toolbar is a optional installed package included with Lazarus - it creates a toolbar panel above the Editor tabs where you can add any Lazarus IDE menu items at runtime...
