Eclipse uses JavaFX to write a helloworkld

Operating system: Ubuntu18.04

Eclipse does not support JavaFX by default and does the following to enable access to JavaFX

1. Right-click the project->bildpath->configure Bild Path, select the Library tab, select Access rules, and click Edit on the right.

Click Add on the pop-up typeaccessrules form, pop-up the edit Access Rule form, resolution option select the Accessible,rule pattern option to fill in "javafx/**"

In this way, you can use JavaFX directly in Eclipse.

Write a HelloWorld try:

 Packagestart;Importjavafx.application.Application;Importjavafx.event.ActionEvent;ImportJavafx.event.EventHandler;ImportJavafx.scene.Scene;ImportJavafx.scene.control.Button;ImportJavafx.scene.control.Label;ImportJavafx.scene.image.Image;ImportJavafx.scene.layout.StackPane;ImportJavafx.stage.Stage; Public classStartextendsapplication{ Public Static voidMain (string[] args) {System.out.println ("Hello,world");    Launch (args); } @Override Public voidStart (Stage primarystage) {primarystage.settitle ("Hello world!"); Button btn=NewButton (); Btn.settext ("Say ' Hello World '"); Btn.setonaction (NewEventhandler<actionevent>() {@Override Public voidhandle (ActionEvent event) {System.out.println ("Helloworld!");                          }             }); Stackpane Root=NewStackpane ();             Root.getchildren (). Add (BTN); Primarystage.setscene (NewScene (Root, 300, 250));          Primarystage.show (); }  }

Note that there is a gtk-message that says "Canberra-gtk-module" cannot be loaded

The solution is as follows:

Open Terminal execute the following command to install the module can be

sudo apt-get install Libcanberra-gtk-module

Run again, snap alive.
