2.工具欄
3.視窗
現在我我的檔案中的建立、打開、另存為；編輯；和設定沒有完成 望高手幫忙~！還有我的浏覽器現在不能浏覽本地HTML檔案~1 我的郵箱是：[email protected] 大家可以把源代碼發到我的郵箱中，分一樣給！

學習中。。
牛人啊，為啥和我寫一樣的東西啊？
儲存的給你寫完了，告訴我怎麼顯示本地的htlm
注意：要顯示頁面，不是代碼。
public void saveFile()
{
try
{
file = new File(currentFileName);
writefile = new FileWriter(file);
String s=paneURL.getText();
writefile.write(s);
writefile.close();
}
catch(IOException ee)
{
JOptionPane.showMessageDialog(this, "Warning ",ee.toString(),
JOptionPane.ERROR_MESSAGE);
}
}
public void saveAsFile()
{
int n=saveAsFileDialog.showSaveDialog(this);
file = saveAsFileDialog.getSelectedFile();
if(n==JFileChooser.APPROVE_OPTION)
{
try
{
currentFileName = saveAsFileDialog.getSelectedFile().getPath();
writefile=new FileWriter(file);
write=new BufferedWriter(writefile);
String s=paneURL.getText();
write.write(s);
write.newLine();
write.flush();
write.close();
writefile.close();
this.setTitle(currentFileName);
}
catch(IOException ee)
{
JOptionPane.showMessageDialog(this, "Warning ",ee.toString(),
JOptionPane.ERROR_MESSAGE);
}
}
}
啊哈哈，我簡直就是一個白癡，現成的東西不會用
public void openFile()
{
int n=openFileDialog.showOpenDialog(this);
if(n==JFileChooser.APPROVE_OPTION)
{
paneURL.setText(null);
file=openFileDialog.getSelectedFile();
try
{
currentFileName = openFileDialog.getSelectedFile().getPath();
url = file.toURL(); //這個是最關鍵的，要把File類型的file變成URL型的。
in = url.openStream();
paneURL.setPage(url);
stringText = paneURL.getText().trim();
}
catch(IOException ee)
{
paneURL.setText(currentFileName);
JOptionPane.showMessageDialog(this, "Opening Error !! ",ee.toString(),
JOptionPane.WARNING_MESSAGE);
}
}
}
