How to listen adding a new file to a folder to show up in JTable?










0















I have a problem with my GUI. I use WatchService and it works well. How can I add this service so that JTable will show a new file?



Maybe there is another solution? Can I ask you for some examples?
My table implements the AbstractTableModel.

    Have the service listener add a row to the JTable. I'm sorry if it sounds so simple, but it is that simple really.

  • You use the addfRow(...) method of the DefaultTableModel to add the row.

I resolved my problem with this, but now if i add new file my table is refreshed but they loose renderer view for jprogress bar and checkbox.
I need help.



 Path path = Paths.get(filePath.getAbsolutePath());
try
Boolean isFolder = (Boolean) Files.getAttribute(path, "basic:isDirectory", NOFOLLOW_LINKS);
if (!isFolder)
Log.error(this, "Path: " + path + " is not a folder");
throw new IllegalArgumentException("Path: " + path + " is not a folder");

System.out.println("Watching path: " + path);
WatchService watchService = path.getFileSystem().newWatchService();
path.register(watchService, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY);

WatchKey key;
while ((key = watchService.take()) != null)
for (WatchEvent<?> event : key.pollEvents())
File files = filePath.listFiles();
customTableDataList.clear();
for (File file : files)
customTableData = new CustomTableData(file);
customTableDataList.add(customTableData);

customTableModel = new CustomTableModel(customTableDataList);


This resolve my problem, table is reloaded but view is not rendering.




 myTable.setModel(customTableModel);



If I remove above and adding (line below), view of my table is correct but only when I click in checkbox (table is reloaded).




 myTable = new Table(customTableModel);



 myTable.repaint();

System.out.println("#LIST: " + customTableDataList + " >>> #SIZE: " + customTableDataList.size());


//Log.info(this, "#LIST: " + customTableDataList + " >>> #SIZE: " + customTableDataList.size());
key.reset();

catch (IOException e)
e.printStackTrace();
catch (Exception e)
e.getMessage();
