如何在警告对话框中设置wraptext选项？我试着这样做:

Alert alert = new Alert(Alert.AlertType.CONFIRMATION);
alert.getButtonTypes().set(0, ButtonType.NO);
alert.getButtonTypes().set(1, ButtonType.YES);
alert.getDialogPane().getStylesheets().add("/styles/style.css");
alert.setGraphic(new ImageView(getIcon(icon)));
Label lb = (Label) alert.getDialogPane().getChildren().get(1);
lb.setWrapText(true); //Attempt to set wrapText option
alert.setTitle(title);
alert.setHeaderText(header);
alert.setContentText(content);

但它不起作用.
