我准备了一个带有按钮和 Jpanels 的 GUI。当在 JFrame 中单击按钮时,需要发生 3 件事。两个大图像(由源包中的路径指定)必须出现在两个单独的 JPanel 上,而一小段文本(我将编写)则出现在一个空的 JLabel 中。问题是我不知道应该如何编写按钮处理代码。我也不知道是否需要实现一些初始化组件才能使其工作。这是一些示例代码:
package db.SuperMarioGFX;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
/**

* @author speterson86
*/
public class EnemyGFX extends javax.swing.JFrame {
/**
* Creates new form EnemyGFX
*/
public EnemyGFX() {
initComponents();
}
/**
* This method is called from within the constructor to initialize the form.
* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.
*
* SuppressWarnings("unchecked"), followed by over 1000 lines of Generated
* Code are below this, but not necessary to include in this code sample!
*/
private void btnBeachKoopaActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
/**
* For 'Land[JPanel]' (Panel-container for a set of buttons, not for
* displaying images)
*
* Note that "pbx" is short for "picture box". Unlike VB, I couldn't
* find any so-called picture boxes when I was building my GUI in
* Netbeans, so I hoped JPanels would be the next best thing to use for
* displaying relatively large (roughly 400 x 400 pixels or less each)
* images. Now, here's the 3 things I need to display on my EnemyGFX
* JFrame when the btnBeachKoopa button is clicked on:
*
* Display "GFX01.png" in pbxDefaultBinFile[JPanel]
* Display "Yoshi'sIsland2.zst, Level #$106" text in lblSaveState[JLabel]
* Display "Land1.PNG" in pbxFixedBinFile[JPanel]
*
* So how would I go about making that happen?...
