Hallo erstmal,
Ich habe ein Problem wenn ich den Inhalt meiner JTextArea als * speichern möchte.
Ich möchte das ich verschiedene Formate auswählen kann (vielleicht auch ein eigenes).
Hier der Code.
import java.awt.*;
import java.awt.event.*;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import javax.swing.*;
import javax.swing.filechooser.FileNameExtensionFilter;
public class Document extends JFrame implements ActionListener
{
/**
*
*/
private static final long serialVersionUID = 1L;
private JTextArea ta;
private int count;
private JMenuBar menuBar;
private JMenu fileM,editM,viewM;
private JScrollPane scpane;
private JMenuItem exitI,cutI,copyI,pasteI,selectI,saveI,loadI,statusI;
private String pad;
private JToolBar toolBar;
public Document()
{
super("Document");
setSize(600, 600);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container pane = getContentPane();
pane.setLayout(new BorderLayout());
count = 0;
pad = " ";
ta = new JTextArea(); //textarea
menuBar = new JMenuBar(); //menubar
fileM = new JMenu("File"); //file menu
editM = new JMenu("Edit"); //edit menu
viewM = new JMenu("View"); //edit menu
scpane = new JScrollPane(ta); //scrollpane and add textarea to scrollpane
exitI = new JMenuItem("Exit");
cutI = new JMenuItem("Cut");
copyI = new JMenuItem("Copy");
pasteI = new JMenuItem("Paste");
selectI = new JMenuItem("Select All"); //menuitems
saveI = new JMenuItem("Save"); //menuitems
loadI = new JMenuItem("Load"); //menuitems

toolBar = new JToolBar();
ta.setLineWrap(true);
ta.setWrapStyleWord(true);

}
public void actionPerformed(ActionEvent e)
{
JMenuItem choice = (JMenuItem) e.getSource();
if (choice == saveI)
{
/*
*Hier was kommt
*
*/
public void speichern()
{
JFileChooser chooser = new JFileChooser();
chooser.showSaveDialog(null);
try
{
String Name = ta.getText();
File file = new File("D:\\"+Name+".txt");
FileWriter fw = new FileWriter(file);
fw.write("Name: "+Name+"
");
fw.flush();
fw.close();
}
catch( IOException ev )
{
ev.printStackTrace();
}
}
/*

*/
}
else if (choice == exitI)
{
System.exit(0);
}
else if (choice == cutI)
{
pad = ta.getSelectedText();
ta.replaceRange("", ta.getSelectionStart(), ta.getSelectionEnd());
}
else if (choice == copyI)
{
pad = ta.getSelectedText();
}
else if (choice == pasteI)
{
ta.insert(pad, ta.getCaretPosition());
}
else if (choice == selectI)
{
ta.selectAll();
}
else if (e.getSource() == statusI)
{
//not yet implmented
}
}
public static void main(String[] args)
{
new Document();
}
}
Mit freundlichem Gruß,
