显示一些文本。现在,我想在文本区域中显示一些可单击的URL以及普通文本,如果用户单击该URL,则URL引用的网页应在新的web浏览器窗口中打开。将JEditorPane与HTMLEditorKit或JTextPane一起使用,并将内容类型设置为“text/html”
…引用的url应在新的web浏览器窗口中打开
以下是从JTextArea打开链接的示例:
JTextArea jtxa = new JTextArea(25,100);
JScrollPane jsp = new JScrollPane(jtxa);
JPanel jp = new JPanel();
jp.add(jsp);
jp.setSize(100,50);
jtxa.addMouseListener(new MouseAdapter()
{
public void mouseClicked(MouseEvent me)
{
if(me.getClickCount()==2) //making sure there was a double click
{
int x = me.getX();
int y = me.getY();
int startOffset = jtxa.viewToModel(new Point(x, y));//where on jtextarea click was made
String text = jtxa.getText();
int searchHttp = 0;
int wordEndIndex = 0;
String[] words = text.split("\\s");//spliting the text to words. link will be a single word
for(String word:words)
{
if(word.startsWith("https://") || word.startsWith("http://"))//looking for the word representing the link
{
searchHttp = text.indexOf(word);
wordEndIndex = searchHttp+word.length();
if(startOffset>=searchHttp && startOffset<=wordEndIndex)//after the link word was found, making sure the double click was made on this link
{
try
{
jtxa.select(searchHttp, wordEndIndex);
desk.browse(new URI(word)); //opening the link in browser. Desktop desk = Desktop.getDesktop();
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
}
}
}
});
JTextArea jtxa=新的JTextArea(25100);
JScrollPane jsp=新的JScrollPane(jtxa);
JPanel jp=新的JPanel();
jp.add(jsp);
jp.setSize(100,50);
jtxa.addMouseListener(新的MouseAdapter()
{
公共无效mouseClicked(MouseEvent me)
{
if(me.getClickCount()==2)//确保双击
{
int x=me.getX();
int y=me.getY();
int startOffset=jtxa.viewToModel(新点(x,y));//在jtextarea上单击的位置
String text=jtxa.getText();
int searchHttp=0;
int-wordEndIndex=0;
String[]words=text.split(\\s”);//将文本拆分为单词。链接将是单个单词
for(字符串字:字)
{
if(word.startsWith(“https://”)word.startsWith(“http://”)查找表示链接的单词
{
searchHttp=text.indexOf(word);
wordEndIndex=searchHttp+word.length();
if(startOffset>=searchHttp&&startOffset查看一个简单的示例。)我会试试,但我想知道用JTextarea是否可以实现此功能?@Sandy:恐怕用JTextarea是不可能的。这只允许您将html内容添加到JTextPane/jEditorPane。我猜您希望文本转换为clickabe超链接(如果可以的话)在你打字的时候。也许你可以详细说明一下你答案中的关键点。这可以让别人更容易理解。
