java - 为什么 Java jFrame setResizable() 无法执行？

Question

此代码由 Netbean 6.8 GUI 生成器自动生成。默认应用程序不包含在 jFrame 中!它仅在 jPanel 中，我不知道如何使其无法重新调整大小。所以我添加了一个 jFrame 来包含所有这些，尽管我设置了它的 setResizable();为假......它仍然可以重新调整大小!这是代码:

    dlg.add(img, BorderLayout.CENTER);

    ResourceMap resourceMap = getResourceMap();
    int messageTimeout = resourceMap.getInteger("StatusBar.messageTimeout");
    messageTimer = new Timer(messageTimeout, new ActionListener() {

            statusMessageLabel.setText("");
        }
    });
    messageTimer.setRepeats(false);
    int busyAnimationRate = resourceMap.getInteger("StatusBar.busyAnimationRate");
    for (int i = 0; i < busyIcons.length; i++) {
        busyIcons[i] = resourceMap.getIcon("StatusBar.busyIcons[" + i + "]");
    }
    busyIconTimer = new Timer(busyAnimationRate, new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            busyIconIndex = (busyIconIndex + 1) % busyIcons.length;
            statusAnimationLabel.setIcon(busyIcons[busyIconIndex]);
        }
    });
    idleIcon = resourceMap.getIcon("StatusBar.idleIcon");

                    statusAnimationLabel.setIcon(busyIcons[0]);
                    busyIconIndex = 0;
                    busyIconTimer.start();
                }

对于冗长的代码，我深表歉意，我不确定哪一部分对这个案例很重要，哪一部分不重要。

如果你知道这里有什么问题，请告诉我

Answer 1

你的代码有错误；我的简单独立测试程序显示 setResizable(false) 工作正常:

package com.businesslink.core.tst.ld.dct;

import java.awt.*;
import javax.swing.*;

public class SwgTestFrame1b
extends JFrame
{

public SwgTestFrame1b() {
    super("SwgTestFrame1b");

    setBackground(Color.white);
    setResizable(false);
    pack();
    }

static public void main(String[] args) {
    new SwgTestFrame1b().show();
    }
}

---

快速搜索您的代码会发现在 mainFrame 上没有调用 show 或 setVisible 的地方；看起来您只显示与 mainFrame 相关的对话框。现在 setResizable 仅在 mainFrame 上完成，不会影响任何作为 mainFrame 子级的对话框。它也不会影响您的 FrameView 使用的框架。

---

PS，还有 FTR，我绝对讨厌不能调整大小的窗口，它们要么是不合适的 GUI 工具包，要么是懒惰的程序员的标志。
