fxruby users - Nov 2008 - how to change a button''s text one by one

Hi all,


I create 3 buttons.  If I click @button_start , at button_word will change its
text one by one based on an array. If I click @button_end the program will end.
My problem here is that  the word on @button_word doesn''t change one by
one, instead they all show up at the same time.

Any idea?


Thanks,

Li

# change the text on @button_word one by one
slice=%w{A,B,C,D,E}

@button_start.connect(SEL_COMMAND) do|sender,selector,data|
	slice.each  do |letter|

@button_end.connect(SEL_COMMAND) do|sender,selector,data|

Your definition of "slice" is an array containing one element:

	slice = %w{A,B,C,D,E}

This evaluates to an array with one element, whose value is the string  
"A,B,C,D,E". I think what you''re going for is:

	slice = %w{A B C D E}

or just:

	slice = ["A", "B", "C", "D",
"E"]

Hope this helps,

Lyle

Hi Chen,

I suggest you use timer to show the text.

Question _your own_ authority.

Hi Lyle,

I change to slice = ["A", "B", "C", "D",
"E"]. But strange thing still happens: I can see the button change to
the last item ''E''  from ''reading word'', but
not to the other itmes of A , B, C, D.

Another question: I read API about FXButton. There are no instance methods such
as #text in this class. But when I query Ruby  on it by code line:
button.public_methods.size it return 414 methods. Where are these methods
defined, by their ancestors and mixins?

Thanks,

Li
