JavaFx 8: open a link in a browser without reference to Application

Question

Have got a Hyperlink. When clicked I want a link to be opened in an external browser.

The usual method cited on the web seems to be:

final Hyperlink         


        

Answer 1

If you want to open a url when you click on a button inside your app and you are using an fxml controller file then you can do the following...

First in your Main Application Startup file get a pointer to the HostServices object and add it to your stage such as...

stage.getProperties().put("hostServices", this.getHostServices());

Then in your fxml controller file get the hostServices object from the stage object and then execute the showDocument() method.

HostServices hostServices = (HostServices)this.getStage().getProperties().get("hostServices");
hostServices.showDocument("http://stackoverflow.com/");

I have a method in my contoller class called getStage()...

/**
 * @return the stage from my mainAnchor1 node.
 */
public Stage getStage() {
    if(this.stage==null)
        this.stage = (Stage) this.mainAnchor1.getScene().getWindow();
    return stage;
}
