为什么Java jFrame setResizeable()无法执行操作?

jframe netbeans swing java

M. A. Kishawy Andy Guibert · 技术社区 · 14 年前

此代码由Netbean 6.8 GUI builder自动生成。默认应用程序未包含在jFrame中!只有在jPanel中,我不知道如何使它变得更大。因此,我添加了一个jFrame来包含所有这些内容,尽管我将其设置为setResizeable();错了…它还是相当大的!代码如下:

    import org.jdesktop.application.Action;
    import org.jdesktop.application.ResourceMap;
    import org.jdesktop.application.SingleFrameApplication;
    import org.jdesktop.application.FrameView;
    import org.jdesktop.application.TaskMonitor;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import javax.swing.Timer;
    import javax.swing.Icon;
    import javax.swing.JDialog;
    import javax.swing.JFrame;

    public class BOSSConverterView extends FrameView {

    public BOSSConverterView(SingleFrameApplication app) {
    super(app);
    JDialog dlg = new JDialog();
    dlg.setUndecorated(true);
    dlg.setModal(true);
    dlg.setLayout(new BorderLayout());
    ImageIcon img = new ImageIcon(getClass().getResource("splash.png"));
    dlg.add(img, BorderLayout.CENTER);
    dlg.setLocationRelativeTo(null);
    dlg.setVisible(true);        
    initComponents();
    ResourceMap resourceMap = getResourceMap();
    int messageTimeout = resourceMap.getInteger("StatusBar.messageTimeout");
    messageTimer = new Timer(messageTimeout, new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            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(idleIcon);
    progressBar.setVisible(false);

    // connecting action tasks to status bar via TaskMonitor
    TaskMonitor taskMonitor = new TaskMonitor(getApplication().getContext());
    taskMonitor.addPropertyChangeListener(new java.beans.PropertyChangeListener() {
        public void propertyChange(java.beans.PropertyChangeEvent evt) {
            String propertyName = evt.getPropertyName();
            if ("started".equals(propertyName)) {
                if (!busyIconTimer.isRunning()) {
                    statusAnimationLabel.setIcon(busyIcons[0]);
                    busyIconIndex = 0;
                    busyIconTimer.start();
                }
                progressBar.setVisible(true);
                progressBar.setIndeterminate(true);
            } else if ("done".equals(propertyName)) {
                busyIconTimer.stop();
                statusAnimationLabel.setIcon(idleIcon);
                progressBar.setVisible(false);
                progressBar.setValue(0);
            } else if ("message".equals(propertyName)) {
                String text = (String)(evt.getNewValue());
                statusMessageLabel.setText((text == null) ? "" : text);
                messageTimer.restart();
            } else if ("progress".equals(propertyName)) {
                int value = (Integer)(evt.getNewValue());
                progressBar.setVisible(true);
                progressBar.setIndeterminate(false);
                progressBar.setValue(value);
            }
        }
    });
}

public void showAboutBox() {
    if (aboutBox == null) {
        JFrame mainFrame = BOSSConverterApp.getApplication().getMainFrame();
        aboutBox = new BOSSConverterAboutBox(mainFrame);
        aboutBox.setLocationRelativeTo(mainFrame);

    BOSSConverterApp.getApplication().show(aboutBox);

默认应用程序未包含在jFrame中!

您不应该创建额外的JFrame,您的面板已经在一个框架中您应该使用类似这样的内容,而不是创建新的框架:

getFrame().setResizeable(false);

L. Cornelius Dol 14 年前

你的代码有错误;我的简单自包含测试程序表明 setResizable(false)

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,不会发现在大型机上调用了show或setVisible;看起来您只显示与大型机相关的对话框。现在,SetResizeable仅在大型机上完成,这不会影响作为大型机子级的任何对话框。它也不会影响FrameView使用的帧。

PS,还有FTR,我绝对讨厌不能调整大小的窗口——它们是GUI工具包不足或程序员懒惰的标志。

填充代码((java.awt.Frame)根);应用中类,完全在方法中 配置窗口 (应用程序类是实例化视图类的类。) 这应该会有帮助
