Ruby Shoes Gui: Continually Updating Paragraphs

Ruby Shoes GUI: Continually Updating Paragraphs

If you're looking to list all files in a directory and refresh the list every second, then I think this is what you're looking for:

Shoes.app do

  stack do
    @btn_exit = button("Exit") {exit}
    @log = para "Logging goes here..."
  end

  every 1 do
    @log.text = Dir.entries('C:/Test').select{|file| file != "."*file.length}.join("\n")
  end

end

Ruby Shoes GUI Secret style not working

Try it this way

  button "Login" do
    username = ask("Enter Username: ")
    password = ask("Enter Password: ", :secret => true)
  end

Shoes GUI toolkit per pixel manipulation possible?

Yep, there is. Most elements accept a :top and :right that let you pick an offset per pixel, and lots of the drawing and shape stuff is per-pixel as well.

How to call Shoes methods from inside an instance method?

Shoes.app { ... } does an instance_eval of the code block. What that means is the that the body of the block gets executed as though self were an instance of Shoes (or whatever class it is using under the hood). What you'll want to do is something like the following:

class MyClass
  def initialize(app)
    @app = app
  end
  def draw
    @app.oval :top => 100, :left => 100, :radius => 30
  end
end

Shoes.app {
  myclass = MyClass.new(self) # passing in the app here
  myclass.draw
}

How can I make simple http requests within a ruby Shoes GUI application?

The problem for me when I tried to run your code was that the Shoes app couldn't connect locally using localhost. Instead of using localhost, use your computer's local IP address.

So just change this:

Net::HTTP.get(URI.parse("http://localhost:3000"))

to this:

Net::HTTP.get(URI.parse("http://10.1.4.123:3000"))

if your computer's local IP is 10.1.4.123.

To see the error logs that confirm this is happening for you, insert this line at the top of your shoes app: Shoes.show_log

Or simply enter cmd+/ on a Mac or ctrl+/ in Windows(?) when you are running your *.rb file in Shoes.app

For me the error that showed up was:

Connection refused - connect(2) for "::1" port 3000
