[ltk-user] new method listbox-delete
by Shawn Betts 28 Jun '07

28 Jun '07

Hi folks, I believe this is missing: (defgeneric listbox-delete (l start &optional end)) (defmethod listbox-delete ((l listbox) start &optional end) (check-type start (integer 0 *)) (format-wish "~a delete ~a ~a" (widget-path l) start (or end "end"))) If it isn't, what function should I be calling? :) -Shawn

[ltk-user] Ltk examples

Hello: I tried to rewrite the widget example program in ltk, but now I'm too busy to complete that work. I send 4 examples about ltk. You could add them to the ltk tarball if you want. I release them in the public domain. Bye! -- Felip Alàez Nadal

[ltk-user] *wish* global
by Shawn Betts 24 Jun '07

24 Jun '07

Hi ltkers, Maybe I'm just not using it quite right, but I'm having trouble cleanly dealing with the *wish* global which, if i understand correctly, is let'd in several places to ensure that functions use the correct wish object. I'm using ltk along with some networking code and so I ltk's :server-event set to nil. The problem is I then have to bind *wish* properly whenever I update the gui from the network code. It's sort of clunky and frustrating. My suggestion: have some or all tk widgets contain a wish slot that stores the connection to wish. That way objects just do the right thing when you use them. For commands that don't require a widget, such as wish-exit, you explicitely pass an ltk-connection object that was given to you when you opened the connection. This seems closer to how clx works. -Shawn

[ltk-user] writing a compound widget
by Russell McManus 13 Jun '07

Are there any examples around of how to write a compound widget in ltk? In particular, I'd like to try to write something like the Notebook widget that's available in perl/tk. -russ
