[fxruby-users] Quitting Extended app via button produces errors

[dave L]

Paul,

Just loaded this into my Linux box (hope this works for your winXP - should i think)
I got caught and still do sometimes event now but have learn to look for my errors.

I suspect if you where to simply change these 2 lines (hope the highlights come through to something like
I have then you should be running.

require "events_ui"  <<<<<< changed the filename of the GUIb code ergo this is changed here!!!

class AmainWindow < MainWindow  <<<<<< see the changes made here???
    def init
       button1.connect(Fox::SEL_COMMAND){ FXApp::ID_QUIT }
    end   # of events
end

if __FILE__==$0
    require 'libGUIb16'
    app=FX::App.new
    w=AmainWindow.new app <<<< see changes made here 
    w.topwin.show(Fox::PLACEMENT_SCREEN)
    app.create
    app.run
end



HTH

Dave.

Subject: [fxruby-users] Quitting Extended app via button produces errors

Hi there, I used foxGUIb to create a UI and a separate file to hold the event actions.

When I try to quit the app (see source code below) using a [Quit] button, I get the following error:
-----
>rubyw extended_quit.rb
extended_quit.rb:5:in `init': uninitialized constant MainWindow::FXApp (NameError)
    from c:/ruby/lib/ruby/gems/1.8/gems/fxruby-1.6.12-mswin32/lib/fox16/responder2.rb:55:in `call'
    from c:/ruby/lib/ruby/gems/1.8/gems/fxruby-1.6.12-mswin32/lib/fox16/responder2.rb:55:in `onHandleMsg'
    from extended_quit.rb:15:in `run'
    from extended_quit.rb:15
>Exit code: 1
-----

=> Question: How do I get the app to quit/exit without showing this error?  When I work with a straight FXRuby app (e.g. hello.rb), the app exits without any error.  I have tried several ways to try to get the app to quit, and while the error message may change, I can't get the error message to go away and just exit cleanly (0).

Please let me know.  Thanks.  Paul.


Here is the code:
(1) extended_quit.rb:
-----
require "quit_ui"

class MainWindow
    def init
       button1.connect(Fox::SEL_COMMAND){ FXApp::ID_QUIT }
    end   # of events
end

if __FILE__==$0
    require 'libGUIb16'
    app=FX::App.new
    w=MainWindow.new app
    w.topwin.show(Fox::PLACEMENT_SCREEN)
    app.create
    app.run
end
-----

(2) quit_ui.rb:
-----
# source generated by foxGUIb 1.0.0

class MainWindow
    def initialize( parent)
        construct_widget_tree( parent)
        init if respond_to? 'init'
    end
    
    def construct_widget_tree( parent)
        @topwin=
        FX::MainWindow.new(parent){|w|
            @mainWindow=w
            w.wdg_name='mainWindow'
            w.width=300
            w.shown=true
            w.y=233
            w.height=100
            w.x=55
            FX::Button.new(@mainWindow){|w|
                @button1=w
                w.wdg_name='button1'
                w.text="Quit"
                w.width=50
                w.height=30
            }
        }
    end
    attr_reader :topwin
    attr_reader :mainWindow
    attr_reader :button1
end
