    <p>I am building a Graphical User Interface, and used a <a href="http://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html" rel="nofollow">FileChooser</a> to pick up the file the user choose, so everything works fine, but now i am trying to get the path of the file selected (made quite easily through a <code>file.getAbsolutePath()</code>).</p> <p>But somehow i can't get it out of the class... i want to have a String path in the class with the listener, which looks like this :</p> <pre><code>private void browseButton(Canvas BasicSelection) { final Button btnBrowse = new Button(BasicSelection, SWT.NONE); btnBrowse.setBounds(70, 29, 68, 23); btnBrowse.setText("Browse"); btnBrowse.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent arg0) { filechooser.createAndShowGUI(path); sbtnBrowse = btnBrowse.getSelection(); } }); launchEvent(); } </code></pre> <p>And here is the action performed when the button is clicked : </p> <pre><code>public void actionPerformed(ActionEvent e) { //Set up the file chooser. if (fc == null) { fc = new JFileChooser(); } fc.addChoosableFileFilter(new Filter()); fc.setAcceptAllFileFilterUsed(false); //Show it. int returnVal = fc.showDialog(FileChooser.this,"Attach"); //Process the results. if (returnVal == JFileChooser.APPROVE_OPTION) { File file = fc.getSelectedFile(); setPath(file); log.append("Attaching file: " + file.getName() + "." + newline); // Here is where i would need to get the file... but how ? } else { log.append("Attachment cancelled by user." + newline); } log.setCaretPosition(log.getDocument().getLength()); //Reset the file chooser for the next time it's shown. fc.setSelectedFile(null); } </code></pre> <p>How can i get the file name out of the class ?</p> <p>EDIT : I already tried with getters and setters but strangely he tried to access the content before i actuallt wrote in it.</p> <pre><code>String path ; /* Rest of the code ... */ public void setPath(File input) { if (input != null) { this.path = input.getAbsolutePath(); System.out.println("path is now set correctly : "); } } public String getPath() { return this.path; } </code></pre>

    1. COIf possible, try to *not* mix SWT and Swing, there is a [`FileDialog`](http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fswt%2Fwidgets%2FFileDialog.html) in SWT which you can use. To your question: Create getter and setter methods or use a `static` `String` variable to store the path...

    2. CO@Baz So you mean i should use the FileDialog **instead** of the JFilechooser, right? Yeah i tried using getter and setter, i did put a String path in my class, but the problem was, when i tried to access it from the outside, the path was null (he wanted to access the path before i had choosed the file). And i don't know how to solve that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
