Certain methods don't work (alert, confirm...)

[mjohanning99]

I've been having some issues with my Shoes. Certain methods just don't seem to work at all. When I try to create a confirm? it gives me the following error

NoMethodError: undefined method 'confirm?' for (Shoes::App:0x00000fa0 "Shoes 4"):Shoes::App Did you mean? confirm method_missing at org/jruby/RubyBasicObject.java:1657 method_missing at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/shoes-core-4.0.0.pre12/lib/shoes/app.rb:107 method_missing at /home/marvin/.rvm/rubies/jruby-9.1.13.0/lib/ruby/stdlib/forwardable.rb:189 block in postscreen at rerutwi.rb:95 eval_block at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/shoes-swt-4.0.0.pre12/lib/shoes/swt/swt_button.rb:26 block in _after_do_redefine_method_with_callback at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/after_do-0.4.0/lib/after_do.rb:99 block in click at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/shoes-swt-4.0.0.pre12/lib/shoes/swt/swt_button.rb:31 run_event_loop at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/swt-4.6.1.1/lib/swt/minimal.rb:107 event_loop at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/swt-4.6.1.1/lib/swt/minimal.rb:90 open at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/shoes-swt-4.0.0.pre12/lib/shoes/swt/app.rb:71 open_gui at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/shoes-core-4.0.0.pre12/lib/shoes/internal_app.rb:125 initialize at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/shoes-core-4.0.0.pre12/lib/shoes/app.rb:52 app at /home/marvin/.rvm/gems/jruby-9.1.13.0/gems/shoes-core-4.0.0.pre12/lib/shoes/app.rb:20 <main> at rerutwi.rb:108

I have tried this on both my Laptop and my Desktop but it doesn't work on either of them. I get basically the same error when trying to create an alert.

Hi there,

seems you are trying to call a method confirm? - it's called confirm - does that solve the problem?

[mjohanning99]

When I try that I get the exact same error message, but it says "undefined method 'confirm', did you mean 'confirm?'"

[PragTob]

Hi,

could you please show the offending code or even better produce a minimal sample? I'm asking because in my testing simple_dialogs.rb and simple_dialogs_outside.rb work just fine.

Thanks!
Tobi

For some reason, when I try the ones you sent it seems to work, but it doesn't work in the program I am currently making. I am not really that good at coding Ruby and especially Shoes yet, so maybe there's something I am missing here. Here is an example where an alert() should appear but it exits in an error instead. The same would happen if I used a "confirm" there.
Also, I am using the exit() method here, because Shoes.quit() also doesn't work.

@Jeytas I'm sorry but that code isn't a complete example, as in there's a Shoes.app do or something missing. I.e. a script that we can execute and that produces the bug is ideal.

Btw. - one of my first shoes projects was also partially a twitter client. Meet infoes :)

edit: Looked at your project a bit, from what I gather it uses URLs, might be that dialogs are broken in that context not sure

Getting the same error on load using the shoes command.

ERROR: undefined method 'alert' for (Shoes::App:0x00000fa0 "testing page"):Shoes::App

Using jruby 9.1.15.0 with shoes-4.0.0.rc1 on High Sierra

class AppComponent < Shoes
  url '/', :index
  url '/login', :login
  def index
    send('login')
  end
  def login
    display_login
  end
  def display_login
    alert("doesn't work")
  end
end
Shoes.app width: 800, height: 600, title: 'testing page'

Thank you a lot @tedma4 !

It might be that we're not including the dialogues module for the URL stuff - I'll check it out.

edit:

Simplified example:

class AppComponent < Shoes
  url '/', :index
  def index
    alert("doesn't work")
  end
end
Shoes.app width: 800, height: 600, title: 'testing page'

[tedma4]

FYI, I got it to work by calling the methods from the class itself. So, from my example above, calling AppComponent.alert('Does now!!!') shows the alert

[PragTob]

@tedma4 yup you can also call them directly on Shoes - fix will be up in a minute :)

[PragTob]

This seems fixed 🎉
