CList widget

nn Here is the simple example of CList class. This program displayes all environmental variables.

Program clist.rb:

require 'gtk'

window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
clist = Gtk::CList.new(['name', 'value'])
clist.set_usize(300, 200)
clist.set_column_width 0, 100
ENV.keys.sort.each {|k| clist.append [k, ENV[k]]}
window.add clist
clist.show
window.show
Gtk.main

Result:
(attention: this result depends gtk-1.0.x. If you execute this program with version 1.2.x, little changes will be occur in look & feel.)

Description:

• clist = Gtk::CList.new(['name', 'value'])
  This creates a 2 columns CList widget object, which titles are 'name' and 'value'.
• clist.set_usize(300, 200)
  This set the widget 300 pixels width, 200 pixels height.
• clist.set_column_width 0, 100
  This set the first column 100 pixels width. The index of the first column is 0.
• ENV.keys.sort.each {|k| clist.append [k, ENV[k]]}
  "ENV" is built-in constant of Ruby. It is (pseudo) Hash which contains environment variable. This adds the pair of one variable name and its value to list. The length of array for "append" method must be equal to the number of CList columns.

Gtk::CList.new(columns)

Gtk::CList.new(['title1', 'title2', ... ])

This method creates a CList widget. When using first style, created CList have "columns" columns but no title. When using second style, created CList have columns with title.
