In code I'm working on, I've found a pattern like PROCEDURE HideIt; BEGIN SomeComponent.Visible := FALSE; SomeComponent.Parent := SELF; SomeComponent.Visible := TRUE; END;
PROCEDURE ShowIt(NewParent: TForm); BEGIN SomeComponent.Visible := FALSE; SomeComponent.Parent := NewParent; ...some more stuff... SomeComponent.Visible := TRUE; ...some more stuff... END; I can't really see what it's good for. I guess, the idea was to preserve the widget, but the widget seems to get freed immediately in the first line. It comes from D7 or older. Does it make sense on Lazarus 1.4 using GTK+? Whenever there's a focused TextField in SomeComponent, there's a segment violation on Linux after HideIt. It looks like an event (lost focus?) gets delivered to its already freed widget. Any thoughts?
