Best way to brake up a string within FXruby?

Hi I have a string inside a FXList that is seperated into columns by spaces.

I will have a need to put this data into editable controls when ever the user clicks on a line.
I thought of using the ruby split(' ') command.

The way i was going to do this was to have it setup like this...

control.text, control.text... = ALine.split(' ')

but i got a error referring to split as being private!
Is there a better way of doing this?

I have googled but for the present i have not found anything meaningful.

anyone able to help?

dave.

Are you sure ALine is a String?

Nataraj S Narayan & David MacMahon,
Thanks for your quick reply.

David,
Yes Aline is a string as it is actually obtained from fxlist and has data like Job No, Date, Time (PC system obtained) plus other entries but i am wanting to ADD to the list.

Nataraj,

Didn't think of doing this!
as i'd just thought these would be in as a system function of FXruby.
Lession learnt :)
many thanks to you both.

Dave

Right still not able to import String functionality into FXruby!

the error i get is this...

C:/Ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- string (LoadError)
from C:/Ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from mymainwin.rb:5
>Exit code: 1

sample of code is this ...

require 'time'
require 'string'

' a method to break a line of text into words that are passed onto texfields for editting.

def breakWord (theword)
@atextfield.text, @btextfield.text, @ctextfield.text, @Dtextfield.text = theword.split(' ')
end

the data being passed into the above method *IS* text so for example string...

"the fox jumped over" would be passed into breakWord and each control will get each word put into.

I do have other requires and they work okay.
I am using ruby 1.8.x on winXP and know the there isn't any problems with ruby.

pointers?
Is there a FXruby function that could be used?

Dave.

PS got the date/time issue sorted

You don't have to import string functionality into FXRuby, or into any other Ruby program. It's built in to the Ruby language, e.g.

"the fox jumped over".split # => ["the", "fox", "jumped", "over"]

When you ask questions like this, or your previous questions about how to determine the date or time, it indicates to me that you might want to step back a bit and get more comfortable with basic Ruby programming. These questions have nothing at all to do with FXRuby.

Maybe it's stupid, but did you try to just make *sure* it's string by
calling its to_s method?

Lye and Bartosz Dz,

Thanks for your replies.

Firstly I'd be the first to admit I'm not the best programmer.
And this highlights it but I DO try to resolve my issues before posting by googling, searching the Rdocs and reading your (Lye) good book for clues on dealing my issue.

I have solved my current problem through using puts in the method to see what i was getting passed into it.

so i had this what i had further down in my code and didn't suspect it as being at fault
breakWord @CRlist3.currentItem Now i have done this breakWord @CRlist3.getItemText(@CRlist3.currentItem)

Lo and behold i got the text associated with the line i had clicked broken down using split(' ').

I must have done a search for a way to capture text when the list was clicked and come across the currentItem method (but it doesn't show up on the list for FXlist in the Rdoc's but setcurrentItem does anyway i can only say i miss understood what it was doing and I did not put in any put's statements prior to today to see what I was getting as this would've shown me my problem).

I hope this posting may help others who are new to FXruby and aren't the best with FXruby/ruby but want to try using this GUI toolkit.

know the volume of traffic isn't high but hope I am not putting people off me.

Rgds,

Dave.

Is it possible to create a pane dynamically

by Soumyanath Chatterjee :: Rate this Message:

Reply to Author | View Threaded | Show Only this Message

Hi!

I am new to FXRuby so excuse me for this stupid question. I need to
enter many different data and trying to create a vertical pane
dynamically using response from a SQL query.

I want these input form to appear in my main window. Created a class
based on FXMainWindow.

--------------- Code snippet ------------
class DbFace < FXMainWindow
attr_writer \
:title,

def addNew
vPane = FXVerticalFrame.new(@hWnd)
dTitle = FXLabel.new(vPane,@title,nil,LAYOUT_FILL_ROW)
end

def initialize(app, pane)
@hWnd = pane
@hApp = app
end
end
----------- End -----------------

I use this class from inside my program. As:

book = DbFace.new(app, @frame)
book.title = "Add new record"
book.addNew

The new dialog fields do not show up with this. Please tell me if I am
doing something wrong. Any example will be great.

It is not a stupid question.

I think you're just leaving out a call to create() for the
newly-constructed widgets. What happens if you add a call to
vPane.create() at the end of your addNew() method?

def addNew
vPane = FXVerticalFrame.new(@hWnd)
dTitle = FXLabel.new(vPane,@title,nil,LAYOUT_FILL_ROW)
vPane.create
end

Let me know if that does the trick. For more background on this, see:

http://www.fox-toolkit.org/faq.html#CREATELATER

Or, even better, buy the FXRuby book and read Chapter 7. ;)

Hope this helps,

Lyle

Hi Lyle,

Thank you for the excellent observation!

Adding a create did the trick. Now the code is working fine.

Hi!

Thanks to Lyle's pointer - .create method has solved the pane creation
problem. But there are other problem - how do I get rid of the pane.
Multiple calls to this class keeps stacking the pane over the old one.

In C++, I would have destroyed the old object - what do I do in FXRuby?

vPane.hide - looks to be a work around; but I think this will keep the
old objects in memory. Please suggest a good way to close the screen.

Try using removeChild with the pane's parent.
