Question

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

Answer 1

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
