package pipeline.ui; import javafx.application.application; import javafx.fxml.fxmlloader; import javafx.scene.parent; import javafx.scene.scene; import javafx.stage.stage; /** * * @author pat */ public class pipelineui extends application { @override public void start(stage stage) throws exception { parent root = fxmlloader.load(getclass().getresource("pipelineui.fxml")); scene scene = new scene(root, 1000, 1000); stage.settitle("pipeline welcome"); stage.setscene(scene); stage.show(); } /** * @param args command line arguments */ public static void main(string[] args) { launch(args); } } the controller code:
package pipeline.ui; import java.net.url; import java.util.resourcebundle; import javafx.event.actionevent; import javafx.fxml.fxml; import javafx.fxml.initializable; import javafx.scene.control.button; import javafx.scene.control.label; import javafx.scene.control.tab; import javafx.scene.control.textarea; import javafx.scene.control.textfield; /** * * @author pat */ public class pipelineuicontroller implements initializable { private label label; @fxml private tab groupstab; @fxml private button addgroup; @fxml private button removegroup; @fxml private button proceedbutton1; @fxml public textarea groupslist; @fxml private textfield groupname; private static final string newline = "\n"; public void handlebuttonaction(actionevent event) { if (groupname.gettext() != "") { string name = groupname.gettext(); groupslist.appendtext(name); groupslist.appendtext(newline); } } @override public void initialize(url url, resourcebundle rb) { // todo } } the fxml code:

this wouldn't run me, because have errors in fxml. handler addgroup button should "#handlebuttonaction" (the "#" indicates belongs controller, , script).
additionally, since handler method takes actionevent it's parameter, should
onaction="#handlebuttonaction" (not onmouseclicked).
user-interface javafx fxml
