get choice bok select value并单击哪个按钮,我需要一个输出。我引用了这个,并在中更改了我的代码
Optional<ButtonType> optional = choice.showAndWait();
if (optional.isPresent()) {
System.out.println(optional.get().getButtonData());
}
这是我的示例代码
public class ChoiceDialogFX extends Application {
@Override
public void start(Stage primaryStage) {
List<String> list = new ArrayList<>();
list.add("/dev/ttyUSB0");
list.add("/dev/ttyS0");
list.add("/dev/ttyS1");
list.add("/dev/ttyS2");
Button btn = new Button();
btn.setText("ChoiceDialog");
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
choiceInputDialog("Test", "Port Select", "Choice", list);
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
public String choiceInputDialog(String title, String headerText, String contentText, List choices) {
Object defaultChoice = choices.get(0);
Collection<String> collection = choices;
ChoiceDialog choice = new ChoiceDialog(defaultChoice, collection);
addCheckBox(choice);
choice.setTitle(title);
choice.setHeaderText(headerText);
choice.setContentText(contentText);
Optional<ButtonType> optional = choice.showAndWait();
if (optional.isPresent()) {
System.out.println(optional.get());
}
return null;
}
private void addCheckBox(ChoiceDialog choice) {
ButtonType buttonType = new ButtonType("Debug", ButtonData.HELP);
choice.getDialogPane().getButtonTypes().add(buttonType);
}
}

btn.setOnAction(新的EventHandler如果您已经为ChoiceDialog指定了确切的类型,那么您在编码时会遇到更少的问题。而不仅仅是
ChoiceDialog choice = new ChoiceDialog( defaultChoice, collection );
做
编辑:
实际上,您可以通过
choice.getSelectedItem();
因此,您可能更喜欢只返回单击按钮的文本
Optional<String> result = choice.showAndWait();
if ( result.isPresent() )
{
System.out.println( "button text = " + result.get() );
System.out.println( "choice = " + choice.getSelectedItem());
}
如何在“替换调试”按钮中添加复选框。@ReeganMiranda设置对话框的自定义内容(请参阅)。
public String choiceInputDialog( String title, String headerText, String contentText, List choices )
{
ChoiceDialog<String> choice = new ChoiceDialog( choices.get( 0 ), choices );
addCheckBox( choice );

{
ButtonBar.ButtonData data = type == null ? null : type.getButtonData();
if ( data == ButtonBar.ButtonData.HELP )
