wxruby users - Nov 2006 - wxSugar control problem

I''m using wx_sugar 0.1.2 with wxruby2-preview 0.0.37 on OSX and am  
coming up with an error when trying to create a SpinCtrl (and quite a  
few others have exactly the same prob.):

#file date_picker.rb

class DatePicker < Wx::Dialog
   def initialize
     super(nil, :title => "Pick a date...")

     @cal = Wx::CalendarCtrl.new(self)
     add(@cal)

     #works fine up to this point, will make a lovely calendar in the  
window if I comment the next 2 lines out...

      @month = Wx::SpinCtrl.new(self) # line 9 - doesn''t like this!
      add(@month)
   end
end

gives error:

ArgumentError:
Error initializing #<Wxruby2::SpinCtrl:0x6267a4>
Sent paramters: [#<DatePicker:0x626934>, -1, #<Wxruby2::Point: 
0x690474>, #<Wxruby2::Size:0x6904b0>, 4, -1, #<Wxruby2::Point: 
0x690474>, #<Wxruby2::Size:0x6904b0>, 4096, 0, 100, 0]
correct parameters are:

pos (Wxruby2::Point)
size (Wxruby2::Size)
style (Fixnum)
id (Fixnum)
pos (Wxruby2::Point)
size (Wxruby2::Size)
style (Fixnum)
min (Fixnum)
max (Fixnum)
initial (Fixnum)

Ruby version: ruby 1.8.4 (2005-12-24) [powerpc-darwin8.7.0]

The SpinCtrl is working fine in the Big Demo, and other types of  
controls can be added in this particular dialog fine. I have tried  
hacking around in keyword_constructors.rb - my idea was to handle the  
above error, and instead of raising it the first time, I tried to  
catch it and then initialize the object just using the parameters  
passed in - so that you could just revert to the normal wxruby (i.e.  
c-style) params if there are any problems with wxsugar. Unfortunately  
this didn''t work and lead to some strange recursion stuff that hurt  
my head.

Anyone got any ideas as to what might be going wrong?

Thanks,

Thanks for the report, sorry for the bug. It''s down to a wrong 
definition of the constructor parameters in wx_sugar.

I''ve checked in the correction, but if you want to patch yourself the 
error is in wx_sugar/lib/keyword_classes.rb

Around line 321 there are two definitions of SpinCtrl''s constructor; 
this is a mistake  itself, and worse, neither is quite right.  Delete 
them both and replace with:

# wxSpinCtrl     A spin control - i.e. spin button and text control
WxSugar.define_keyword_ctors(''SpinCtrl'') do
  wx_ctor_params :value => ''''
  wx_ctor_params :pos, :size, :style => Wx::SP_ARROW_KEYS
  wx_ctor_params :min => 0
  wx_ctor_params :max => 100
  wx_ctor_params :initial => 0
  wx_ctor_params :name => ''spinCtrl''
end

Oops, please let me know. I had to manually copy these so it''s not 
unlikely I''ve made some mistakes or omissions. If you get weird
''correct
parameters'' - eg with two Size arguments, or ArgumentErrors about
''arg 2
of type XXX'' please check against the docs, have a look in 
keyword_classes and report.

The docs should be correct as they were translated automatically from 
the C++ onees.

Thanks again

Firstly, thank you for your amazingly swift reply. I''m slightly  
pleased that it wasn''t just me doing something really stupid ;)

I''ve gone through most of the controls on the docs index page, and  
have come up with these changes:

line (371 on mine, but then I''ve fiddled a bit...)
change:
WxSugar.define_keyword_ctors(''RadioBox'') do

to
WxSugar.define_keyword_ctors(''RadioButton'') do

and then both radio boxes and radio buttons will work ;)

This helps with SpinButtons: (Missing AFAIK)

WxSugar.define_keyword_ctors(''SpinButton'') do
   wx_ctor_params :pos, :size, :style => Wx::SP_VERTICAL
   wx_ctor_params  :name => ''spinButton''
end


Change the Slider to this....

WxSugar.define_keyword_ctors(''Slider'') do
   wx_ctor_params :value => 0
   wx_ctor_params :min_value, :max_value
   wx_ctor_params :pos, :size, :style => Wx::SL_HORIZONTAL
   #  wx_ctor_params :validator, :name => ''radioButton''
end

... and all of the controls are now working (N.B. I haven''t tested  
the BitmapButton and the StaticBitmap because I''m not in the mood to  
figure out bitmaps in wx right now ;)


Please note that I''m far from a ruby expert and so I have no idea if  
I''m doing the right thing above. All I can say is that the mods seem  
to work for me!

Would quite like to get involved more in the project - perhaps more  
on the documentation side than the voodoo coding side - when I have  
some more free time after Christmas. I''ve been meaning to write some  
kind of wxSugar intro / tutorial, simply because it seems so much  
easier to pick up if you''re used to ruby syntax.

WxRuby in general is very promising, especially with the nice syntax,  
and once everything is a little smoother it will be miles ahead of  
the other toolkits I''ve looked at. Good work guys ;)

Alex

also added:

# Window
WxSugar.define_keyword_ctors(''Window'') do
   wx_ctor_params :pos, :size, :style
   wx_ctor_params :name => ''window''
end


Is this not there for a reason (i.e. just creating windows on their  
own is a "bad thing")? I''ve just been using them as an area
to draw on.

Regards,
Alex

... Thanks very much for the fixes. I''ve applied those to SVN and also 
added a few other classes that are now available in wxruby2 eg 
HtmlWindow, PrintDialog.

I''ll put a release out shortly with these fixes
in.

Glad to hear it''s doing what it''s meant to do... I think an
intro would
be very welcome. It''s on my todo list but stabilising the core wxruby2 
is our priority for now

A lot of WxWidgets/WxPython code uses Panels rather than Windows to draw 
on. I think there is a reason for this but I don''t know what it is...
