下面是编程之家 jb51.cc 通过网络收集整理的代码片段。

编程之家小编现在分享给大家，也给大家做个参考。

 require "wx"
 include Wx

 # a new class which derives from the Wx::App class
 class HelloWorld < App
   # we're defining what the application is going to do when it starts
   def on_init  
     # it's going to make a frame entitled "Hello World"
     helloframe = Frame.new(nil,-1,"Hello World")
     # it's going to put the text "Hello World" in that frame
     StaticText.new(helloframe,"Hello World")
     # and then it's going to make the window appear
     helloframe.show()
   end
 end
 # and this line makes it actually do it!
 HelloWorld.new.main_loop
