在较低分辨率下扩展Java GUI

Question

我正在创建一个产品计算器类应用程序，当我以较低分辨率打开程序时，我正在努力扩展。以下是我希望程序看起来的方式：

它在较低分辨率下的外观（在此图中为1366x768）：

我正在为我的应用程序使用migLayout，我将发布以下代码

import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.Box;
import javax.swing.JTextField;
import java.awt.BorderLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.text.NumberFormat;

import javax.swing.JLabel;
import javax.swing.JSlider;
import javax.swing.JTextArea;
import javax.swing.JButton;

import javax.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.SwingConstants;
import javax.swing.JSeparator;
import javax.swing.JTextPane;
import net.miginfocom.swing.MigLayout;

首先，您需要根据屏幕大小调整JFrame的大小：

final Dimension screenDimensions = Toolkit.getDefaultToolkit().getScreenSize();
frame.setBounds(
       (int) (screenDimensions.width * 0.05), (int) (screenDimensions.height * 0.05),
       (int) (screenDimensions.width * 0.9), (int) (screenDimensions.height * 0.9));

JFrame的内容也应根据相对屏幕尺寸进行缩放。

您还应该认真考虑使用XML文件来包含UI元素以减少代码的大小，请参阅https://eclipse.org/windowbuilder/
