JTextPane实现文字图片插入、发送

图片插入

分类：【C、Java与网络编程】

其实不需要JEditorPane，Java提供的JTextPane本身就可以实现文字、图片同时插入，并发送。这里界面设计与功能实现分成2个文件来写。界面是用Netbeans画的，里面有2个JTextPane和2个JButton，文件为ImageTextPaneForm.java。功能实现的类为ImageTextPaneController.java：

ImageTextPaneController.java

import java.awt.event.ActionEvent;

import javax.swing.ImageIcon;

import javax.swing.JButton;

import javax.swing.JFileChooser;

import javax.swing.JFrame;

import javax.swing.JTextPane;

import javax.swing.text.BadLocationException;

import javax.swing.text.Element;

import javax.swing.text.StyleConstants;

import javax.swing.text.StyledDocument;

public class ImageTextPaneController {

public static void add2(JTextPane inputJTpane,

JTextPane outputJTpane,

JButton insertButton,

JButton senon,

JFrame jf){

insertButton.addActionListener((ActionEvent e) -> {

JFileChooser chooser = new JFileChooser();

chooser.setFileSelectionMode(JFileChooser.FILES_ONLY);

int result = chooser.showOpenDialog(jf);

if (result == JFileChooser.APPROVE_OPTION) {

inputJTpane.insertIcon(new ImageIcon(chooser.getSelectedFile().toString()));

}

});

senon.addActionListener((ActionEvent e) -> {

StyledDocument inputSDoc = inputJTpane.getStyledDocument(); //获取读取的StyledDocument

StyledDocument outSDoc = outputJTpane.getStyledDocument(); //获取欲输出的StyledDocument

for (int i = 0; i < inputSDoc.getLength(); i++) { //遍历读取的StyledDocument

if (inputSDoc.getCharacterElement(i).getName().equals("icon")) { //如果发现是icon元素，那么：

Element ele = inputSDoc.getCharacterElement(i);

ImageIcon icon = (ImageIcon) StyleConstants.getIcon(ele.getAttributes());

outputJTpane.insertIcon(new ImageIcon(icon.toString()));//插入icon元素

} else {//如果不是icon（可以判断是文字，因为目前只有图片元素插入）

try {

String s = inputSDoc.getText(i, 1);

outSDoc.insertString(outputJTpane.getCaretPosition(), s, null);//从光标处插入文字

} catch (BadLocationException e1) {

e1.printStackTrace();

}

});

//===========End of senon

}

生成的界面文件：

public class ImageTextPaneForm extends javax.swing.JFrame {

private static final long serialVersionUID = 1L;

public ImageTextPaneForm() {

initComponents();

ImageTextPaneController.add2(jTextPane2, jTextPane1, jButton2, jButton1, this);

}

@SuppressWarnings("unchecked")

jSplitPane1 = new ;

setDefaultCloseOperation(;

jSplitPane1.setOrientation(;

jSplitPane1.setResizeWeight(0.8);

jScrollPane1.setViewportView(jTextPane1);

jSplitPane1.setTopComponent(jScrollPane1);

jScrollPane2.setViewportView(jTextPane2);

javax.swing.GroupLayout jPanel1Layout = new ;

jPanel1.setLayout(jPanel1Layout);

jPanel1Layout.setHorizontalGroup(

jPanel1Layout.createParallelGroup(

.addComponent(jScrollPane2, javax.swing.GroupLayout.DEFAULT_SIZE, 345, Short.MAX_VALUE)

);

jPanel1Layout.setVerticalGroup(

jPanel1Layout.createParallelGroup(

.addComponent(jScrollPane2, javax.swing.GroupLayout.DEFAULT_SIZE, 186, Short.MAX_VALUE)

jSplitPane1.setRightComponent(jPanel1);

jButton2.setText("插入图片");

jButton1.setText("发送");

javax.swing.GroupLayout layout = new ;

getContentPane().setLayout(layout);

layout.setHorizontalGroup(

layout.createParallelGroup(

pack();

}// </editor-fold>
