Hi All, First post, so a little bit about me: I am a SW engineer and have been one for over 20 years, increadible as that may sound. I have programmed on the Mac before in Ada95, Obj-C and Java (but I have had a pause of about 5 years from the Mac). Now that MacRuby seems to gain some foothold I'd like to get back to the mac and make the jump from Obj-C to MacRuby. I work in Xcode, and have just started a new MacRuby Core-Data Application. The first goings look good, but in implementing my first window controller I ran into a (little?) problem: I cannot get the state of a checkbox: status = @myCheckbox.state always returns a Fixnum with value 0. regardless of the visual representation of the checkbox (i.e. selected or not) The checkbox should be mapped correctly because: myTitle = @myCheckbox.title does indeed give me the title I set in the IB. I checked the archives but did not find any discussions about this. There was something about checkboxes and hotcocoa, but I do not use hotcocoa. The best solution would be a simple stupid mistake on my part :-) Any takers? Regards, Rien.
