Hi Community
i wana use this JAVAFX Code

in JrubyFX

class HelloWorldApp < JRubyFX::Application
def start(stage)
stage.initStyle(StageStyle::TRANSPARENT)
stage.title = “Hello World!”
stage.width = 600
stage.height = 400
text = Text.new(“Hi”)
text.setFont(Font.new(40))
box = VBox.new
box.getChildren.add(text);
scene = Scene.new(box,600,400)
scene.setFill(null)
stage.setScene(scene)
stage.show
end
end

HelloWorldApp.launch

but i have Problem in scene.setFill(null)
I dont know how should I use setFill in JrubyFx

2

Maybe scene.setFill(nil) or scene.fill = nil?

In Ruby, nil is the keyword for null references. It also adds attribute
accessor syntax so that you can interact with Java objects with
accessors as if they were POROs. E.g.
scene.fill=nil

Actually, what is the status of JRubyFX? I haven’t seen new version of
it. Is it still in development?

Thanks!

I think what you want (transparent scene) you can get by looking at
samples/analog_clock.rb in the source repo. As others have said
setFill(nil) because null is not a valid value in Ruby.

style="-fx-background-image: url("Bg1.gif");

Can you add -fx-background-color: transparent to this? I checked your
Bg1.gif and has the background in the alpha channel.

The scene.fill = nil is missing in your code. Try this:

class HelloWorldApp < JRubyFX::Application
  def start(stage)
    stage.fxml HelloWorldController
    stage.initStyle(StageStyle::TRANSPARENT)
    stage.scene.fill = nil
    stage.title = "Hello World!"
    stage.width = 800
    stage.height = 600
    stage.show
  end
end

Sorry, I can’t test this, because I haven’t installed JRuby and JRubyFX.
