我需要创建一个按钮以在javafx中打开窗口。不摇摆。无fxml。
一个。你能有多个阶段吗？我认为不是，但我看到一个网站另有说法。
B.我是否必须使按钮创建一个扩展应用程序的类，覆盖start（） ...
我看了以下内容无济于事。我见过很多，我只是不明白那里有什么或如何实现它。如何修改我的代码以使其工作？

Button to push new customers onto queue. Opens a new popu window (stage) to enter customer information.
btSave.setText("Add");
btSave.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
//SCENE 3 OF 3: ADD SCENE, Pane & Nodes
GridPane addPane = new GridPane();
//add nodes
addPane.add(new Label("Customer Name"), 1,1);
addPane.add(tfName, 1,2);
addPane.add(new Label("Size of Party"), 1,3);
addPane.add(tfParty, 1,4);
addPane.add(new Label("Customer Phone Number"), 1,5);
addPane.add(tfPhone, 1,6);
addPane.add(btSave, 1, 7);
Scene addScene = new Scene(addPane, 300, 250);
primaryStage.setTitle("Add Customer to Queue");
primaryStage.setScene(addScene);
primaryStage.show();
// Customer cust = new Customer();
// cust.name = tfName.getText();
// cust.party = Integer.parseInt(tfParty.getText());
// cust.phone = Integer.parseInt(tfPhone.getText());
// qLine.offer(cust);
}
});
I would like the button to show "Add" and would like it to open a new window when clicked.
如果你想打开一个新的阶段，下面的代码可以帮助你。
Button btSave = new Button();
btSave.setText("Add");
btSave.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
//SCENE 3 OF 3: ADD SCENE, Pane & Nodes
GridPane addPane = new GridPane();
//add nodes
addPane.add(new Label("Customer Name"), 1,1);
addPane.add(tfName, 1,2);
addPane.add(new Label("Size of Party"), 1,3);
addPane.add(tfParty, 1,4);
addPane.add(new Label("Customer Phone Number"), 1,5);
addPane.add(tfPhone, 1,6);
addPane.add(btSave, 1, 7);
Stage addStage = new Stage();
Scene addScene = new Scene(addPane, 300, 250);
addStage.setTitle("Add Customer to Queue");
addStage.setScene(addScene);
addStage.show();
}
});
