I have swing app where in main window, thrue JFileChoser i get absoluthe filepath.
public Form() {
setVisible(true);
setContentPane(content);
setSize(400,500);
setTitle("Deklaracja pacjenta");
setResizable(false);
Output.setLineWrap(true);
Output.setFont(new Font("Serif",Font.PLAIN,20));
Output.setEditable(false);
msgScroller = new JScrollPane();
msgScroller.setViewportView(Output);
msg.add(msgScroller);
browseButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
String filename = File.separator;
browser = new JFileChooser(new File(filename));
browser.setPreferredSize(new Dimension(600,400));
FileNameExtensionFilter ff = new FileNameExtensionFilter("xml files (*.xml)", "xml");
browser.addChoosableFileFilter(ff);
browser.setFileFilter(ff);
int zwrot = browser.showOpenDialog(content);
if (zwrot == JFileChooser.APPROVE_OPTION ){
selFile = browser.getSelectedFile();
browsePath.setText(String.valueOf(selFile));
browsePath.setEditable(false);}
else
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); }});
Basen on this path then i parse xml file.
I would like to work on the same path in another window but i dont know how to do this. For now the other windows using file which i add to project director, called "deklaracja"
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse("deklaracja");
I would like to use the file which user chose in JFileChoser in previous window insted of "deklaracja". I tried to pass variable "selFile" but i doesnt work. In second class i pass variable like this:
public void xmladder() throws ParserConfigurationException, TransformerException, SAXException, IOException {Form form = new Form();
String path = form.selFile;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.parse(path);
That way make another issue, it build next, the same swing window.
