更改JDatePicker中formattedText字段和按钮之间的默认填充

Question

我想在JdatePicker中增加formattedTextField和Button之间的默认间隔。 我尝试在按钮组件上使用setMargin（新的Insets（0,100,0,0）但是会更改按钮内组件的边距 Here is an image of what is happening right now

下方字段的文本字段和日历按钮之间有一个小间隙。我想在顶线引入相同的差距

我尝试了DatePickerButton.setMargin(new Insets(0,100,0,0)，但这不起作用

JDatePicker myDatePicker = JDateComponentFactory.createJDatePicker();
  myDateButton.setShowYearButtons(true);
  myDateButton.setTextEditable(true);
  myDateButtonComponent = (JComponent) myDateButton;
  myDatePickerTextField = ((JDatePickerImpl)myDateButtonComponent).getJFormattedTextField();
  myDatePickerTextField.setName("date-Picker");
  myDatePickerTextField.setText(EMPTY_STRING);
  myDatePickerTextField.setPreferredSize(new Dimension(95,20));
  myDatePickerTextField.setEnabled(true);

  ((JDatePickerImpl) myDateButtonComponent).getComponent(1).setPreferredSize(new Dimension(22, 22));
  myDatePickerTextField.setFocusLostBehavior(JFormattedTextField.PERSIST);
  myDateButton = ((JButton) ((JDatePickerImpl) myDateButton).getComponent(1));
  myDateButton.setText(EMPTY_STRING);
  myDateButton.setOpaque(false);
  myDateButton.setIcon(Icons.calIcon);
  myDateButton.setName("last-published-date-button");
  myDateButton.setEnabled(true);
