如何使java swing JFrame正确调整大小 [英] how to make a java swing JFrame resize correctly

问题描述

我想知道为什么我不能在下面调整我的框架的大小，并且随着我调整框架的大小，所有组件的大小都会越来越小.谢谢！！！

I'm wondering why I can't resize my Frame below and have all of the components resize smaller and bigger as I resize frame. Thank you!!!

public class TPASimulatorGUI extends JFrame{
    JPanel mainPanel = new JPanel();
    BoxLayout layout = new BoxLayout(mainPanel,BoxLayout.Y_AXIS);       
    mainPanel.setLayout(layout);

                // add things to main panel

    JPanel it = new JPanel(new FlowLayout(FlowLayout.LEADING));

    it.add(mainPanel);

    this.getContentPane().add(it);
    this.setSize(new Dimension(1190,770));
    this.setVisible(true);

}

推荐答案

JPanel it = new JPanel(new FlowLayout(FlowLayout.LEADING));
it.add(mainPanel);

FlowLayout 始终遵循添加到其中的组件的首选大小.

A FlowLayout always respects the preferred size of the components added to it.

摆脱它"面板并尝试使用

Get rid of the "it" panel and try just using

//this.getContentPane().add(it);
add(mainPanel);

框架的默认布局是 BorderLayout，它将尝试增加/减少添加到其中的所有组件的大小.

The default layout for a frame is a BorderLayout which will try to increase/decrease the size of all components added to it.
