问题描述
我现在想往jTextPane里添加图片，就和QQ聊天框似的。jTextPane.setContentType("text/html");例如：jTextPane里的内容为：怎么就不好使了我在这个时候的鼠标指针在【怎么】的后面，我想添加一个图片表情<imgsrc=http://cache.soso.com/img/img/e102.gif>但是添加的不是这怎么的后面而是在<html>的这个位置添加了一行图片标签ml>下面是例子：----------------------------------------------------------------------------<imgsrc="file:/D:/Project/XEditor/bin/org/vorld/xeditor/tools/tageditor/ico/02.GIF">ml><p><imgsrc="http://cache.soso.com/img/img/e100.gif">怎么<b>就不</b><fontcolor="#99ff66">好使了</font></p>-----------------------------------------------插入代码：StringBuffersb=newStringBuffer();sb.append(jTextPane.getText());intend=jTextPane.getSelectionStart();if(faceIco==null)return;sb.insert(end,"<imgsrc=http://cache.soso.com/img/img/e102.gif>");jTextPane.setText(sb.toString());jTextPane.updateUI();
