标签: imageicon

只使用绘画方法,我的图像最初不会显示.一旦我最小化了Java窗口并调整其大小,图像就会显示出来.有什么代码我不见了吗？

public class Lil extends JFrame {

Image image = Toolkit.getDefaultToolkit().getImage("images/Untitled.png");

public Lil(){

    setTitle("flame");
    setBackground(Color.WHITE);
    setSize(400, 400);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setResizable(false);
    setVisible(true);
}

public void paint(Graphics g){

    g.clearRect(0, 0, 400, 400);        
    g.drawImage(image, 60, 25, null);
    //repaint();
}   

public static void main(String [] args){    
        new lil();  
    }
}

我正在使用Mac上的Eclipse设计GUI,我想让我JButton只显示我设置的Icon.它在Mac OS上看起来很好,但是当我将它导出到jar文件并在Windows操作系统上运行时,JButton看起来像这样:

边界都是EmptyBorder.

我做错了什么？怎么能让后面的广场消失？

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;


@SuppressWarnings("serial")
public class Picture extends JFrame{

    public static void main(String[] args){

        new Picture();

    }

    public Picture(){

        this.setTitle("Picture");
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel p = new JPanel();
        ImageIcon pic = new ImageIcon("TestImage.jpg");
        p.add(new JLabel(pic));
        this.add(p);
        this.pack();
        this.setVisible(true);
        System.out.println(pic);
    }

}

这段代码只是显示一个折叠的框架.我希望包(); 方法调用会调整我的.jpg图像周围的框架,对吗？

我已经可以听到第一个问题,是的,图像与我的项目包文件夹位于同一文件夹中.

我正在使用Eclipse IDE.

我还添加了println(); 声明查看Image引用返回的内容并返回"TestImage.jpg".我以为它会在内存中返回图像的地址.

我整个上午一直在阅读论坛,如果不复制和使用其他人更复杂的代码,我无法找到任何可以帮助我的东西.我尽量保持这个尽可能简单,这样我就不会混淆自己.

在此先感谢您的帮助.

我的第一个问题:

我一直试图解决这个问题几天,但我已经到了失去耐心的地步.以下是一些代码和我的项目结构.

问题:如何getResources()在eclipse中和导入jar后工作？

谢谢您的帮助.

public enum Icons {
    XXX("src/resoruces/icons/xyz.png");
    private ImageIcon icon;
    Icons(String path) {
       try {
           // will fail miserably in eclipse and after exporting to jar
           URL imageURL = getClass().getClassLoader().getResource(path);
           icon = new ImageIcon(imageURL);
       } catch (Exception e) {
           // works like a char in eclipse and after creating the jar file
           // with the files in the same directory
           System.out.println("getResoruce() did not work");
           icon = new ImageIcon(path);
       }
   }

我想测试一个带有简单png图像的程序.我写了一个简短的程序来做到这一点,但我似乎无法让路径正确.我已经检查过,再次检查,重新检查,并检查了我的路径名称四倍,但没有正确,但无论我做什么,这个图像都不会显示.我使用了Oracle在ImageIcon文档(creaetImageIcon())中编写的一个简短的类来实现这一目标,但它似乎没有帮助.我将在下面发布整个程序,因为它很短.

package practiceImages;

import java.awt.BorderLayout;
import java.awt.Toolkit;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class ImageIconGUITest {

    public static void main(String[] args) {
        ImageIconGUITest gui = new ImageIconGUITest();
        gui.display();
    }

    private ImageIcon createImageIcon(String path, String description) {
        java.net.URL imgURL = getClass().getResource(path);
        if (imgURL != null) {
            return new ImageIcon(imgURL, description);
        } else {
            System.err.println("Couldn't find file: " + path);
            return null;
        }
    }

    private void display() {
        JFrame frame = new JFrame();
        JLabel label = new JLabel(createImageIcon(
                "Users/Evan/javaItems/Sprites_and_Other_Art/green.png", …

所以我想在每次按下按钮时替换JLabel中的ImageIcon.我做了它,因此图像,标签和GridBagConstraints是公开的.当我试图改变它虽然没有任何反应.

我是以错误的方式来做这件事还是？

谢谢!

我是一个新的程序员,我有一些问题,我已经浏览了一个图片到我的GUI(并在文本框中设置路径),它显示在标签上,但标签尺寸设置只有100,100而图片很多更大,所以当我打开/显示它到标签它被裁剪,无论如何,它是否自动调整大小到标签大小？下面是我在浏览按钮和打开对话框上的逻辑代码,请任何人告诉我我错在哪里..

我正在制作一个依赖于网格中的瓷砖的java游戏.我在GridLayout中使用了ImageIcon和JLabel.我在创建GridLayout时将垂直和水平都设置为零,并且所有使用的图像都没有额外的空间.

解决这个问题的最佳方法是什么？

//Sets up the game canvas
private void setUpCanvasPanel(){
    //Adjusts the panel settings
    canvasPanel.setLayout(new GridLayout(Main.diameter, Main.diameter, 0 ,0));

    //Adds panel to masterpanel
    resetc();
    c.gridx = 0;
    c.gridy = 1;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 1.0;
