[英]Java Swing Thumbnail View of Images to select image
如何在Java中的JTabbedPane的選項卡中生成或顯示圖像的縮略圖視圖,並允許用戶單擊該圖像以顯示在JTabbedpane的其他選項卡中?
import javax.swing.*;
import java.awt.*;
import java.awt.Event.*;
import java.io.File;
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;
import java.io.IOException;
public class SwindDesign {
public static void main(String[] args) throws IOException {
JFrame frame = new JFrame("Split Pain");
frame.setSize(700, 500);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new GridLayout());
//panel
JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
panel.add(new PicturePanel());
JTabbedPane jtp = new JTabbedPane();
jtp.addTab("Set Image", panel);
jtp.addTab("Compare Image", new JButton());
frame.add(jtp);
}
}
class PicturePanel extends JPanel {
File folder = new File("C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures");
File[] listOfFiles = folder.listFiles();
ImageIcon[] img ;
JComponent lblimg;
JTabbedPane jtp = new JTabbedPane();
private BufferedImage[] b = new BufferedImage[10];
public PicturePanel() throws IOException {
for (int i = 0; i < listOfFiles.length; i++) {
System.out.println("chek panth"+listOfFiles[i].getName().toString());
b[i] = ImageIO.read(new File("C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures/" + listOfFiles[i].getName().toString()));
}
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponents(g);
Graphics2D g2 = (Graphics2D) g;
int k = 10;
for (int j = 0; j < listOfFiles.length - 1; j++) {
g2.drawImage(b[j], k, 0, 100, 100, null);
k = k + 75;
}
}
}
好吧,這是我在這里嘗試繪制的圖像,我想強制加載並顯示圖像,這樣我就可以單擊圖像並在另一個選項卡中將其打開以編輯圖像,我如何能夠知道可以通過使用傑利斯特,但我不知道。 請給我建議一下
這里有一些提示可以幫助您:
要在其他選項卡中顯示圖像:
要獲得更多幫助,請向我們展示您嘗試過的事情,如果可以發布一個簡短的示例代碼來演示您的問題,可以做得更好。
對於注釋中描述的另一個要求:
boolean isSelected = false;
JButton jButton;
void imageClickTest() throws MalformedURLException, IOException {
final JFrame frame = new JFrame("Demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 400);
frame.setLayout(new BorderLayout());
final JTabbedPane tabbedPane = new JTabbedPane();
JPanel pane = new JPanel();
JButton button;
pane.setLayout(new BorderLayout());
button = new JButton("I'm second button");
button.setIcon(new ImageIcon(ImageIO.read(new URL("http://cdn5.iconfinder.com/data/icons/ie_Financial_set/24/26.png"))));
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
JButton button = (JButton) e.getSource();
if(isSelected) {
System.out.println("two selected");
button.setBorder(BorderFactory.createEtchedBorder());
isSelected = false;
JSplitPane jSplitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
jSplitPane.add(button);
jButton.setBorder(BorderFactory.createEtchedBorder());
jButton.setText("First click me");
jSplitPane.add(jButton);
jSplitPane.setDividerLocation(150);
tabbedPane.addTab("Image Comparision", jSplitPane);
}
}
});
pane.add(button, BorderLayout.SOUTH);
button = new JButton("First click me");
button.setIcon(new ImageIcon(ImageIO.read(new URL("http://cdn4.iconfinder.com/data/icons/REALVISTA/web_design/png/24/testimonials.png"))));
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
JButton button = (JButton) e.getSource();
button.setBorder(BorderFactory.createLineBorder(Color.RED, 5));
button.setText("Now Click on second button.");
jButton = button;
isSelected = true;
}
});
pane.add(button, BorderLayout.NORTH);
button = new JButton("I'm just extra button");
button.setIcon(new ImageIcon(ImageIO.read(new URL("http://cdn2.iconfinder.com/data/icons/crystalproject/64x64/apps/kservices.png"))));
button.setEnabled(false);
pane.add(button, BorderLayout.CENTER);
tabbedPane.addTab("ImagePane", pane);
frame.add(tabbedPane, BorderLayout.CENTER);
frame.setVisible(true);
}
這只是演示代碼,您可能需要根據需要進行修改。 這只是向您展示如何監視2個組件的點擊並使它們進入另一個選項卡。
希望您對此提出不同的問題,我可能得到一些支持/接受的答案,或者最好的賞金或最差的不贊成票。
