[fxruby-users] trouble with program code separation

Help,

I have a foxGUI gernerated file named monitorwindow and a ruby file called
sqlite3_calls.rb

I want to have my monitorwindow make calls to sqlite3_calls.rb and pass through
parameters to it so i can get data to display to the screen.

I have tried making the code (which currently has only ONE method in it called
rec_to_find) a class and a module but cannot get the link to work.

based on the success i had with example ONE of the user guide ( although it only
used a mouse click) i get this error.

/sqlite3_calls.rb:18:in `rec_to_find'': undefined method
`execute'' for nil:NilClass (NoMethodError)
    from monitorscreen.rbw:65:in `construct_widget_tree''
    from
C:/Ruby1.8/lib/ruby/gems/1.8/gems/fxruby-1.6.16-x86-mswin32-60/lib/fox16/responder2.rb:55:in
`call''
    from
C:/Ruby1.8/lib/ruby/gems/1.8/gems/fxruby-1.6.16-x86-mswin32-60/lib/fox16/responder2.rb:55:in
`onHandleMsg''
    from monitorscreen.rbw:206:in `run''
    from monitorscreen.rbw:206>Exit code: 1
here is the code in sqlite3_calls.rb - as a ruby program this works - well as a
definition of class it does.

require ''sqlite3.rb''

module Dbase   
  def initialize
    @db = SQLite3::Database.new( "customer" )
 end
 
 def rec_to_find(table, colname, tofind)
  stmt = "select cust_nos, caddress, cname, contact, notes, on_stop,
phone_nos from #{table} where #{colname} = ?"
  row = @db.execute(stmt,tofind) # this is the line it''s borking on -
why??
    @rec = []    
   row.each do|fld|           
     @rec = fld
   end   
   return @rec   
 end
end

I ahve tried using :: insetad of the fullstop but i get the same error!!

also tried having the require sqlite3.rb in the file below but it fails there
too - same error.
here is some of the code from the mainscreen.rb file.

# source generated by foxGUIb 1.0.0
require ''sqlite3_calls.rb''

class MainWindow
  
    def initialize( parent)   
        extend Dbase    
        @mydb = Dbase
        construct_widget_tree( parent)
        init if respond_to? ''init''
    end
    
    def construct_widget_tree( parent)

code I''ve inserted to get the customer data returned.

row = rec_to_find(''customer'', ''cust_nos'',
@dice_code.text)

any help would be appreciated.

dave.

[fxruby-users] trouble with program code separation

Yes I thought so too and tried doing this

extend Dbase
@db = Dbase.new
but it borks because the code is a module not a class!

so how would i use it as a class and thus eliminate the problem.

I''ve tried all i know (with my limited knowledge of fxruby/foxGUI &
ruby)

Tried to make sqlite3_calls.rb a subclass of monitorscreen.rb which is generated
by foxGUI but not managed it.

your help appriciated.

Dave.

[fxruby-users] trouble with program code separation

Henon,

Just looking at the code snippet below and want to ask if i should have
everything in sqlite3_calls.rb wrapped in a init define as that''s what
got my 1st sample program working from the user guide.

e.g.

module Dbase
  def init
    # original code put in here
  end

end

rgds,

dave.

[fxruby-users] trouble with program code separation

Thanks Meinrad for your reply,

I had tried doing something like this but it didn''t work in the last
couple of days - Grrrr.

Now before when i had the code inside the foxGUIb generated file when i entered
something into the textfield which is named @acc_code I had it so that the value
was put into a label (which just happened to hold the word Address on the screen
- this was more for me to see that the enter key worked or not.

Now the code below this fails! - so it''s two steps forward 1 back.

I readily admit that i''m not the brightest programmer so what seems
logical sometimes for me when it''s not shown is a mistery hense i go a
bit overboard sometimes to explain my problem.

So I''ve commented out all references to my program sqlite3_calls.rb to
try and get the keypress to work
that is when the ENTER key is press i want the value to be shown on a label just
to prove it works.

Once that''s done then it''s one step to uncomment the
references to SQLite3_calls and pass the value through to get a customer record
returned and to have some values displayed on screen.

My current code for MainWindow - foxGUIb generated code & my hand coded
event handler code.

yours or that of others on this list would be greatly appreciated

dave,
I don''t see the whole code, so I can not exactly tell you how to fix
your problem. maybe
a small example will help you:


class MainWindow # generated by foxguib
     def initialize( parent)  
         construct_widget_tree( parent)
         init if respond_to? ''init''
     end
    

     def construct_widget_tree( parent)
       # here the gui is created by foxguib code
    end
end
  
# you don''t want to change the above autogenerated class in case you
want to change it later and regenerate it.
# everything that MainWindow should do that is not provided by foxguib goes in a
subclass:

class DBWindow < MainWindow # your code
  def initialize(parent)
    super
    # do your stuff here for example:
    @mydb = Dbase.new
  end
end
hth,
-- Henon

lot''s snippted

[fxruby-users] trouble with program code separation

Have you run my code?
what results did YOU get - text entered appear in label4 (aka Address)?

for me running the program (has the code generated by foxGUIb) it fails to pass
any event triggers to the code i had written so when i type in 12345 i see it in
the textfield but the text in label4 (Address) is unchanged and when the enter
key is pressed again no change to the text displayed (changing my code from a
class to a module does nothing, changing the include to an extend does nothing
either).

From my experiments of trying different things to try and get the two to
interact I have no events being fired OR passed through to my code.

could you _or_ anyone else using foxGUIb1.0.0 try the code attached in my
previous email see what results they get?

this is VERY frustrating for me as i did have the code working when the event
code was inside of foxGUIb generated code.

Dave.

[fxruby-users] trouble with program code separation

Just tried this as an experiment.

what i did was to change the init if respond_to? ''init'' line
within the foxGUIb code to a puts ''yes'' if respond_to?
''init''.

Now
using Sicite i expected to see in the output screen yes displayed
either during program execution or after the program is closed.

But nothing happened!! so i can only think that the generated code
doesn''t know anything about my code.

If that is so then i copied and pasted the unit test across to my code and ran
my code and got no response either.

dave.


# source generated by foxGUIb 1.0.0

class MainWindow
 
    def initialize( parent)  
        construct_widget_tree( parent)
        puts ''yes'' if respond_to? ''init''
    end
   
    def construct_widget_tree( parent)
        @topwin        FX::MainWindow.new(parent){|w|
            @mainWindow=w
            w.wdg_name=''mainWindow''



                 My code written tonight after viewing your reply.
require ''monitorscreen.rb''
#require ''sqlite3_calls.rb''

#include Dbase
class Fxwindow_code < MainWindow
 
  def initialize(parent)
      super
        #@mydb = dbase.new
  end
 
  def init
# just put the characters to a label on the screen - easy debug solution for me
to see
# if the user entry gets passed through
#                   - when there is a key press - SEL_KEYRELEASE message is sent
