textField.setPadding(new Insets(5, 10, 5, 10));

alignment

文本对齐方式

textField.setAlignment(Pos.CENTER);

width

格式化

textFormatter用来控制输入内容的格式化

整形格式化

UnaryOperator<TextFormatter.Change> integerFilter = change -> {
    String newText = change.getControlNewText();
    try {
        Integer.parseInt(newText);
        return change;
    } catch (Exception e) {
        return null;
    }
};
textField.setTextFormatter(new TextFormatter<Integer>(integerFilter));

实现方式

Java实现

public static VBox demo1() {
   VBox vBox = new VBox();
   vBox.setPadding(new Insets(10, 10, 5, 20));

   TextField textField = build(null, "文字靠右");
   vBox.getChildren().add(textField);

   textField = build(null, "文字靠左");
   textField.setBorder(new Border(new BorderStroke(Paint.valueOf("blue"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
   textField.setAlignment(Pos.CENTER_LEFT);
   vBox.getChildren().add(textField);

   textField = build("内容1", "文字靠右");
   textField.setBorder(new Border(new BorderStroke(Paint.valueOf("green"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
   textField.setEditable(false);
   vBox.getChildren().add(textField);

   textField = build("内容2", "文字靠右");
   textField.setDisable(true);
   textField.setBorder(new Border(new BorderStroke(Paint.valueOf("black"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
   vBox.getChildren().add(textField);

   textField = build("内容3", "visible");
   textField.setVisible(false);
   vBox.getChildren().add(textField);

   return vBox;
}

private static TextField build(String text, String promptText) {
   TextField textField = new TextField();
   textField.setBorder(new Border(new BorderStroke(Paint.valueOf("red"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
   textField.setPadding(new Insets(5, 10, 5, 10));
   textField.setTooltip(new Tooltip(text + "Tooltip"));
   textField.setText(text);
   textField.setPromptText(promptText);
   textField.setAlignment(Pos.CENTER_RIGHT);

   textField.setMinWidth(100);
   textField.setPrefWidth(100);
   textField.setMaxWidth(200);

   textField.setMinHeight(50);
   textField.setPrefHeight(50);
   textField.setMaxHeight(100);

   return textField;
}
