Does anyone know of any sample code for restoring a window's position and size in wxRuby?

A:
YAML would be a better choice to serialize the prefs, but here I just store a comma-delimited string in the prefs.txt file.
require "rubygems"
require "wx"
include Wx
class MyApp < App
def on_init
left, top, width, height = *prefs
position = Point.new(left, top)
size = Size.new(width, height)
main = Frame.new(nil, -1, "Title", position, size)
#when the window closes, save the location
main.evt_close do |event|
save_window_location(event.get_event_object)
event.skip
end
main.show()
end
private
def save_window_location(frame)
self.prefs = [
frame.position.x,
frame.position.y,
frame.size.width,
frame.size.height
]
end
#load the prefs and return them as an array
def prefs
location = []
begin
location = File.read(prefs_filename).split(',').map{|s| s.to_i}
rescue Exception
#file didn't exist, or read failed
end
location = [100, 100, 300, 300] if location.size != 4
return location
end
#save the prefs as a comma-delimited string
def prefs=(prefs_array)
File.open(prefs_filename, 'w') do |prefs_file|
prefs_file << prefs_array.join(",")
end
end
def prefs_filename
'prefs.txt'
end
end
MyApp.new.main_loop
