jfilechooser

I have a question about the JFileChooser in Swing. I'm trying to get multiple file extensions in the drop-down box, but have no idea how to do it. There is the method extFilter = FileNameExtensionFilter(description, extensions); that I can then use by writing fileChooser.setFileFilter(extFilter); however, as you can see, this only supports one option in the drop-down list. How do I add more? I think you want the addChoosableFileFilter method. Read the tutorial . You can simply create a filter that subclasses FileFilter and call the method I outlined above with that filter as an argument. I'm

private void openMenuActionPerformed(java.awt.event.ActionEvent evt) { DBmanager db = new DBmanager(); if (!db.getCurrentUser().equals("Admin")) { JOptionPane.showMessageDialog(this, "You are Not Allowed to Run Applications"); JFileChooser fileChooser = new JFileChooser(); fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY); fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("PDF Documents", "pdf")); fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("MS Office Documents", "docx", "xlsx", "pptx")); fileChooser.addChoosableFileFilter(new FileNameExtensionFilter(

I am trying to set the directory path in JFilechooser through something like this(using commons-io ) : String fileContents = IOUtils.toString(new FileInputStream("path.txt")); File theDirectory = new File(fileContents); filechooser = new JFileChooser(); fileChooser.setCurrentDirectory(theDirectory); filechooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); I'm using getCanonicalPath() to get the path and write in the file path.txt path = file.getCanonicalPath(); I don't intend to put all my code here,but I'm sure that the program writes and reads the path in path.txt. I don't get any

JFileChooser fc = new JFileChooser(); int option = fc.showSaveDialog(NewJFrame1.this); if(option == JFileChooser.APPROVE_OPTION){ String filename = fc.getSelectedFile().getName(); String path = fc.getSelectedFile().getParentFile().getPath(); int len = filename.length(); String ext = ""; String file = ""; if(len > 4){ ext = filename.substring(len-4, len); } if(ext.equals(".xls")){ file = path + "\\" + filename; }else{ file = path + "\\" + filename + ".xls"; } toExcel(jTable1, new File(file)); } this is how i save my table to excel it works fine but i want to import these datas after i restart

I'm having a little problem when I change Locale at runtime. The Goal I have to change the Locale of my application language according to a configuration file. This locale does not necessarily be the same of the host/OS locale nor the JVM default locale. Moreover, I can't modify user.language when I call the application. Then, I must do that at runtime. The Problem Summarizing my code, I read the configuration file and get the different options (including locale). After that, I initialize the application environment according to these configured options. After, I build my frame and starts the

I am developing a java application for which I need only .xml files. Now I want to show only .xml files in JFileChooser whenever user wants to save a file or open a existing file. Is this possible to show only .xml files? Java You can use JFileChooser API to achieve your task. For Open only .xml file // create a filechooser; JFileChooser chooser = new JFileChooser(cwd); FileNameExtensionFilter xmlfilter = new FileNameExtensionFilter( "xml files (*.xml)", "xml"); chooser.setDialogTitle("Open schedule file"); // set selected filter chooser.setFileFilter(xmlfilter); Also, go through javax.swing
