wxruby users - Apr 2007 - wxSugar 0.1.15 released

Hi

WxSugar 0.1.15 is now available via gems and download from rubyforge.

This is a minor feature release which adds a couple of new facilities:

* enumerable_controls: treats ListCtrl and ControlWithItems classes, 
such as ComboBox, ListBox, CheckListBox as Ruby enumerables
* adds Window#has_style?

The former is meant to give much more rubyish access to the contents of 
GUI controls which present the user with a list of item to choose from:

# basic iteration
listbox.each { | i | puts listbox.string(i) }

# iterate with string labels
listbox.each | i, string, data |
  puts "Item #{string} is at position #{i}, and has client data
#{data}"
end

# access strings and item data as arrays
puts listbox.strings[1] # Retrieve the label at position 1

# add a string
listbox << ''foo''

# search list contents
idx = listbox.index(''foo'') # finds the position of the item
labelled ''foo''
idx = listbox.index(foo) #  find the position of the item with data foo

# enumerable methods
listbox.select { | i | listbox.checked?(i) }

These are meant as experimental methods - feedback welcome.

Woot on enumerable_controls, that''s going to make my life way easier :)
