JTable wider jScrollPane

irl last edited by

Can you please tell me how to make the table broader than the scruples that live on, and access to the invisible part through the horizontal cover? ScrollPane can both blend and horizontal and vertical, only horizontal is not activated and the hidden area of the table is displayed when the size of the foam is changed.

First, I recommend declaring the JTable model in the class, so whenever you need it just do table.getModel(model)The error must not have declared JTable in the constructor (public (classe utilizada)) In class should do DefaultTableModel model = new DefaultTableModel(String[](Seus campos) and in the builder do (nomedatabela) = new JTable(model)That should solve the problem. If you don't, I'm sorry, but I'm also a beginner._

In the question you mention, https://es.stackoverflow.com/a/78223/29967 I gave you the official Google code to create a file on Drive. If you analyze it well, you'll see that the same code shows, in the end, how to get the id from the newly created file through getDriveId(): final private ResultCallback<DriveFileResult> fileCallback = new ResultCallback<DriveFileResult>() { @Override public void onResult(DriveFileResult result) { if (!result.getStatus().isSuccess()) { showMessage("Error while trying to create the file"); return; } showMessage("Created a file with content: " + result.getDriveFile().getDriveId()); } };

From your log we can analyze that the problem is in question of memory - OutOfMemory.This usually occurs by the size of the images you are trying to render! I recommend you redesign your app.I noticed you have a FrameLayout that contains one ImageView as a background. Is that it? If so, remove this and use the property android:background="@drawable/..."

A solution without changing your code much is to add one more condition after which checks if the character is digit, which will check if the character is not a floating point too:for (int i = 0; i < s.length(); i++) { Character caractere = s.charAt(i); if (!Character.isDigit(caractere)) { if(!caractere.equals('.')){ valido = false; break; } } } But since the goal is to allow only numbers with floating point, I think using TableModel It's much easier. What I would need is just to define in the method https://docs.oracle.com/javase/7/docs/api/javax/swing/table/AbstractTableModel.html#getColumnClass(int) that in the second column is type Float. See the example below:import java.awt.BorderLayout; import java.awt.EventQueue; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class JTableTest extends JFrame { public void createAndShowGUI() { Object columnNames[] = { "Any type Column", "Only Float Column",}; DefaultTableModel model = new DefaultTableModel(null, columnNames) { @Override public Class<?> getColumnClass(int columnIndex) { return columnIndex == 1 ? Float.class : super.getColumnClass(columnIndex); } }; model.addRow(new Object[]{}); JTable table = new JTable(model); JScrollPane scrollPane = new JScrollPane(table); this.add(scrollPane, BorderLayout.CENTER); pack(); this.setLocationRelativeTo(null); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); } public static void main(String args[]) { EventQueue.invokeLater(new Runnable() { @Override public void run() { new JTableTest().createAndShowGUI(); } }); } } Running:

You use sync on the monitor. MongDB.thisat the time you want to send a message to other flows, your method is challenging. notify() is already outside synchronization, which means the monitor is missing.You can use it. notify() When you have a monitor. Otherwise, an attempt to cause notify() to a non-existent monitor IllegalMonitorStateException♪

If using DefaultTableModel the command below already solves:((DefaultTableModel) suaTable.getModel()).setRowCount(0); According to https://docs.oracle.com/javase/8/docs/api/javax/swing/table/DefaultTableModel.html#setRowCount-int- , the method setRowCount defines the number of lines that the default model should have, if the defined size is smaller than the current size of lines, the excess lines will be discarded.Just put right at the beginning of your search method, replacing suaTable by the correct variable of your JTable.Adapting to the search code, you should also change the way you will add the items, as the above method will zero the list of objects DefaultTableModel, and use setValueAt will burst ArrayOfBoundException. Add new lines using addRow:private void pesquisar() { conexao.getTransaction().begin(); //limpaTabela ((DefaultTableModel) suaTable.getModel()).setRowCount(0); String jpql = ("select c from Cliente c where c.nome like :cNome"); Query query = conexao.createQuery(jpql); query.setParameter("cNome", txtCliPes.getText() + "%"); List<Cliente> cliente = query.getResultList(); for (Cliente cli : cliente) { tblClientes.addRow(new Object[]{cli.getId()}); } conexao.getTransaction().commit(); //Usar a Biblioteca rs2xlm.jar para preencher a tabela // tblClientes.setModel(DbUtils.resultSetToTableModel(rs)); }

No, you don't. 1.The database will grow over time, and it won't be possible for the client to pass it all in an acceptable time, and it can't work at all. 2.You didn't specify you had a database.

The problem arose because of the error in my table model. By fixing this mistake, JTable can easily display thousands of columns. And I understand that the number of columns is limited only to the memory that is available.

In your case, sealing is just a copy of the file on the server. Usually, the hosts themselves indicate which catalogue the user files can be located. If there's a street/little server, in principle, you can be located anywhere, but in the case of go binary either in the home catalogue or in the binary web server folder. It's also fashionable to make it through dockerfile.Ssh/sftp (usual mode), ftp (old mode but already dying) can be copied through the host admin (started but not enough).To get everyone to work, we need to figure out how it works first. You can, with nginx, you can't. Example http://lesnoy.name/golang/%D0%BD%D0%B0%D1%81%D1%82%D1%80%D0%BE%D0%B9%D0%BA%D0%B0-nginx-%D0%B4%D0%BB%D1%8F-golang-%D1%81%D0%B0%D0%B9%D1%82%D0%B0/ ♪Example of nginx configurationserver { listen 80; server_name lesnoy.name; # домен location / { root /app/; include fastcgi_params; proxy_pass http://localhost:9001; } } And in the code, you just need to listen at the right place.http.ListenAndServe(":9001", nil) Files just need to be copied. The literature on this subject is a lot, just read any manual for php/python/web programmers.The port to which everything will be located will determine in your case nginx (parameter) listen 80) To listen to the local nginx and go the binary in the example above - port 9001.If we decided to use the sqlite base, it's just a regular file for the hoster. So, if the base grows up, you'd probably be predicated on the size limit on the disk, and possibly on the peak of the disk. The file itself needs to be located in a private place (to be unavailable from the outside world, but not much, suddenly, necessary).Will any sanctions be applied by the host for eating my base with many resources?You can't just file it. It's likely to look like it's over on the disk.Of course you should know a little go. It is desirable to know what HTTP/GET/POST requests are. A little knowing HTML/javascript (theoretically, the bacon developer may not do so, but in practice there are rarely clean baeends.)

PBKDF2 is a password hashing function(*); it uses a configurable number of iterations (to make it as slow as is appropriate) and a salt (to deter all kinds of parallelism in attacks). To verify a password, the hash is recomputed, and should yield the same value. To perform this recomputation, you need to use the same number of iterations and the same salt value; otherwise you will get a distinct output and will be none the wiser. A new salt shall be generated for each new registered password (e.g. whenever a new user account is created, and also whenever a user changes his password), so it must be stored along with the hash value. The iteration count should also be stored, because it may be modified at some point. In the code you link to, the count is a constant (static final), but its conceptual role is to counter the increase in performance of computers over time: you use the number of iterations to make each password hashing as slow as you can tolerate, because it will also make it slow for the attacker. When you buy a new, faster server, you may want to increase the iteration count (i.e. modifying the source code and recompiling the application, with a higher count). However, in that case, you do not want to invalidate existing, stored hashed passwords. Thus, you need to know, for each stored hash, how many iterations were used for that specific hash. This is why the iteration count is stored along with the salt and the hash value itself. (*) Strictly speaking, a password-based key derivation function, but let's keep things simple.

I think what might be happening is that you're trying to set your buttons looking for a control inside the view that triggers the onClick(): public void seleccionRojo(View view) { ImageView colorVerde, colorNaranja, colorRojo; colorVerde = view.findViewById(R.id.insidadVerde); ... } In this case the view that shoots onClick() it's the same button, so look it inside it view.findViewById(R.id.insidadVerde); returns a null and therefore setBackgroundResource() He'll make a mistake.Try toly declare your buttons globally and sedate them only once within the method onCreate()ImageView colorVerde, colorNaranja, colorRojo; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tuviewlayout); colorVerde = findViewById(R.id.insidadVerde); colorNaranja = findViewById(R.id.insidadNaranga); colorRojo = findViewById(R.id.insidadRojo); } So you'll save yourself from declaring them onClick corresponding to each button.

As I said before, my solution would be to store all the selected rifs. I'd do it like that:1- Make use of the LinkedList class to store the rifLinkedList<Integer> listaRIF = new LinkedList<>(); create an event to listen to the jtable private void jTable1MousePressed(MouseEvent evt) { int fila = jTable1.getSelectedRow(); listaRIF.add(Integer.parseInt((String) jTable1.getValueAt(fila, 0))); } What he'll do is capture every time you're selecting a cell. The following would be: Create a "Clear" button where you will go all the rif you have selected in the previous method. private void jButton1ActionPerformed(ActionEvent evt) { for (int i = 0; i < listaRIF.size(); i++) { //haces la eliminacion como lo planteaste hace un rato System.out.println(listaRIF.get(i)); } }
