How to get instance of Application object?

[novakmi]

Sometimes it is necessary to have access to the instance of Application. For example to call getHostServices() or getParameters(). Is there any way to do it? Seems like GroovyFX hides this instance completely.

You may just use the closure parameter of type groovyx.javafx.GroovyFX

Sample groovy class:

import static groovyx.javafx.GroovyFX.start

start { app ->

    stage(title: 'GroovyFX web site', width: 500, height: 200, show: true) {
        scene(fill: groovyblue) {
            stackPane {
                button('GroovyFX web site', onAction: {
                    def js = app.hostServices.showDocument('http://groovyfx.org/')
                })
            }
        }
    }
}

Thanks, it works :-) I was not aware app can be added to start closure.
