Unfortunately, most of these properties cannot be set like that, because the control does not exist at that place. Currently there is no other way to solve that problem than setting the property manually in a show listener:

Code: Select all

clauses     new(Parent) :-         formWindow::new(Parent),         generatedInitialize(),         addShowListener(             {  :-                 sciLexer_ctl:hScrollbar := false,                 sciLexer_ctl:extraAscent := 12             }),         ...
I will see if we can find a solution to this for the future.
