fxruby users - Aug 2004 - Fox 1.3.7 and FXRuby 1.2.1

Doh!

After deciding to upgrade to Suse 9.1 I had difficulties trying to make Fox 
1.2.4. So, on a lark I tried Fox 1.3.7 which configure/make/make installed 
with nary a glitch. But, of course, now I''m back to reinstalling my
Ruby
stuff and discovered, as stated, FXRuby 1.2.1 works with the Fox 1.2.x 
versions. Doh!

Will there be a FXRuby 1.3.x sometime in the near future? Or is it still to 
unstable to deal with?

thanks,

OK, well, we need to address that problem, then! Any details?

OK.

Yes, FXRuby 1.2.x is only intended for fox-1.2.x.

The answers are "no" and "yes", respectively. ;)

FOX 1.2 has only been the "new stable" version of FOX for a month or
so
now, and FOX 1.3 is now the unstable development branch. Because the 
latter is unstable, its API is likely to change pretty frequently and 
so FXRuby would need to keep in lock-step with it for the two to remain 
compatible -- and this is just more than I''m willing to sign up for. At
some point, probably not soon, Jeroen will signal that he''s slowing 
down development of FOX 1.3 and getting ready to transition it to the 
API-frozen, stable, FOX version 1.4. It is at that time I would start 
the machinery to update FXRuby to 1.4.

Lyle,

   I noticed that there were two ''empty'' entries that were
similar...

FXToolTip
and
FXTooltip

   I''m betting that the second one is old since the 1.2 way is to use
UpperCamelCase... either way, nothing gets loaded when I click on
them... is that intentional?

   Second item... the FXTreeListItem shows the parameter
''opened'' as a
writeable parameter... is that correct? I always used
''expanded=true''
to open a sub tree... maybe the ''opened'' parameter is supposed
to be
read-only?

Thanks!

Dear all

I have a problem that is probably really stupid, but that I cannot solve  
at the moment and I''m wondering if
someone has an idea of what''s going wrong .. mainly inspired by the  
cookbook snippet of Lyle

http://www.fifthplanet.net/cgi-bin/wiki.pl?Cookbook/Making_A_Snapshot_Of_A_Widget

I''ve done a small function in my code to take snapshots of widgets from
inside my application in Ruby ..
here it is the code


######################################################################

# Create a snapshot of the drawable, where drawable is
# any FXDrawable subclass
def makeSnapshot(filename, drawable)

   completeName = File.basename(filename).match(/(.*)\.(.*)/)
   extension = completeName[2] unless completeName == nil

   case extension
   when "gif"
     snapshot = FXGIFImage.new($FredMW.getApp(), nil,  0,  
drawable.getWidth(), drawable.getHeight())
   when "bmp"
     snapshot = FXBMPImage.new($FredMW.getApp(), nil,  0,  
drawable.getWidth(), drawable.getHeight())
   when "jpg"
     snapshot = FXJPGImage.new($FredMW.getApp(), nil,  0,  
drawable.getWidth(), drawable.getHeight())
   when "png"
     snapshot = FXPNGImage.new($FredMW.getApp(), nil,  0,  
drawable.getWidth(), drawable.getHeight())
   else
     FXMessageBox.error(self, MBOX_OK, "Error on file format",
"Please, use
a file extension among (gif, bmp, jpg, png).")
     return
   end

   snapshot.create()

   dc = FXDCWindow.new(snapshot)


   dc.drawArea(drawable, 0, 0, drawable.getWidth(), drawable.getHeight(),  
0, 0)
   dc.end()

   snapshot.restore()

   FXFileStream.open(filename, FXStreamSave){|stream|
     snapshot.savePixels(stream)
   }
end

######################################################################


The problem is that this function works great on Windows, without any  
problem .. on Linux instead it produces broken images (
I cannot open the PNG with Gimp since it says something about a PNG broken  
.. the BMP format can be open but there is trash in the image, not the  
widget) .. any idea of what can be different between windows and linux on  
that particular function?

I''m using Ruby 1.8.1 and FXRuby 1.0.25

Thanks for the help, Riccardo :)
