I'm a beginner in java. I would like to ask, how to insert JButton on JTable..
View Replies View RelatedI've almost finished building an Editor in Java, but i'm a bit stuck on creating a JCheckBox that saves your credentials (as in password only) . I would like it to be on a JPanel under the password input box and above the Login and Register buttons.
Code:
Login.java (Main class for this problem)

The main thing here is using GridLayout, which is what im currently working with but can't seem to get it under the password input box.. check: [URL] ....
I'm displaying a table with several read-only pieces of data, and a checkbox field that toggles the row color. The background color for the checkbox is not toggling correctly. I put together a SSCCE:
import java.awt.Color;
import java.awt.Component;
import java.util.ArrayList;
import java.util.List;
[code]....
If I comment out the Nimbus look and feel, it works as expected. I googled this problem and found one possible solution on Stack Overflow. Their suggestion is:It's a bug in the synth-installed renderer, quick hack is to force the rendering checkbox opacity to true: ((JComponent) table. get Default Renderer(Boolean.class)).setOpaque(true);
I tried using this line and setting the opacity to true, but it renders the background white. I'm using Java 1.7.0_25.
I would like to get a checkbox within a table to fire an event when it's clicked rather. I gave tried putting in a TableModelListener but the the event only seems to trigger when I click on another column (as if the table is waiting to see if I will change my mind) before moving on.
I have also looked at the setValue of the TableModel itself.
Do I need to put an ActionListener on each checkbox or have I missed something ?
There are 8 JCheckboxes, which are already added to panel and aligned in group layout. From which, I have selected one JCheckbox. Then the resultant GUI should contain only remaining 7 JCheckboxes and selected one should temporarily removed or hide from GUI . Is it possible? If so, how?

How can I make the JTextField to popout when a JCheckBox is selected? I tried putting it under the general if statement and under the if statement which is inside the general if statement.
I would like to put the answer of JCheckBox inside of a JTextArea. How to call the answer of JCheckBox if its check the response should be Yes if its unchecked the response should be No, and the yes/no answer should be appear inside JTextArea. But my problem is inside the JTextArea the answer from a JTextField and JComboBox is also there, and they should be appear in a parallel. I attached the physical appearance of the GUI.

My JTable has a row, row number 0, which I always want to be at the top.I tried the following two approaches, both without success:
1- Use a custom table cell renderer for the header, and create a header of two rows. the second row is my JTextField.
Problem: I cannot get the JTextField to function properly. (I've seen examples with a checkbox in the header, but that one just reacts to a click somewhere on the header, my textfield must be editable).
2- Use the first row of the table. This works quite nice. However, I must prevent row 0 to be re-ordered when sorting the table.
I was thinking to add a prefix (either something like "___" or "zzz" depending on current sorting mode), but I do not know which methods to adjust for this exaclty.
Another approach would be to have N textfields above the JTable in some layout (or two JTable's on top of each other).
However, Then I would need to react to the re-ordering and re-sizing of all columns as well, which does not seem easy to me.
Can I use Jlist instead of Jtable for showing database table data (select * from employee) in my code?
View Replies View RelatedI have encountered a very tricky spot in a project that i am working on. I must have a JTable to programmatically select the very last row in an AbstractTableModel. I have tried every thing but nothing works so far.
The problem is is that the JTable only scrolls down to the second last table row in the model? What am i missing?
//Show the very last row in a tablemodel object using the method updateTableRows
//after an "insert action event" occurred
public void updateViewMode(String name,
java.util.List<NetworkSwitch> list,
boolean flag) {
CableTableModel model = cableTable.getCableModel();
[code]....
What happens is that the only row that gets selected is the second last row of the total rows iny AbstractTableModel object, "CableTableModel"
What am i missing?
I am preparing a small solution. Below is how the functionality works.
1. Login Screen
2. Successful Login will take to a MDI Form
3. Click the menu, a JInternalFrame will open in the JDestopPane.
4. JInternalFrame has a JTable.
5. JInternalFrame has a JButton available for adding new data.
6. When JButton is clicked, a new JInternalFrame is popped up with some JTextField and JButton to save the data.
7. After saving the data (after insert query), a JDialog is opened to upload Logo (update query for BLOB), There are two buttons in the JDialog, one is for uploading the image, another one is uploading it later.
8. The logo is displayed in the JDialog and if the JButton, for upload is pressed, update the database and reload the JTable in the JInternalFrame is called.
My challenge is in point 8. The function is called properly, but the table is not getting refreshed.
JButton in JDialog for uploading the Logo
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
JOptionPane.showMessageDialog(this, "Image Uploaded Successfully");
companyConfig cc = new companyConfig();
//cc.reloadTable();
cc.updateTable();
this.dispose();

I've been creating a jTable where I can add / edit /delete new entries. Now i have 2 Questions :
1) My column 0 is filled with the row-number. I created a variable and with each "add" it adds +1 to the variable. That works, but as soon as i delete 1 row there is a gap ( 1..2..4..5..).
My question: Is there another way then mine to handle this?
2) The table is/should be working as some kind of database. The user is able to add Information (height, width,...). Now I want to sum the entries of 1 column (length,...). But as they´re objects I didn´t find a way.
My question: How can I sum the entries of 1 column of a table?
i have this code when i selected a node it display the attribut and value of it in JTextArea but i want it into table :
public void valueChanged( TreeSelectionEvent event )

TreePath path = jtree.getSelectionPath();
String a = changeString(path);
Hashtable env1 = System.getProperties();
env1.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env1.put(Context.PROVIDER_URL, "ldap://localhost:11389/");

I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.
public class LeftPanel extends JPanel {
private static final long serialVersionUID = -2311952438693382407L;
private RightPanel rPanel;
public LeftPanel(){
Dimension size = getPreferredSize();
size.width = 250;

I have a JTable with the model " Names " , " Quantity " and " Unit " .
I'm coding a program where you get the ingredients names.
So i need to get the whole row of one column and String it all up together,because i need to store it in mySql and i have already set it all as String.
how i can do this ?
My code are as follows :
JTable Code:
DefaultTableModel model = (DefaultTableModel)table.getModel();
if(!txtQty.getText().trim().equals("")){
model.addRow(new Object[]{ingCB.getSelectedItem().toString(),txtQty.getText(),unitCB.getSelectedItem().toString()});
}else{
JOptionPane.showMessageDialog(null,"*Quantity field left blank");
}
Getting the values and for storing :
for(int i = 1; i<= i ; i++){
ingredients = table.getName();
}
This is for loop is wrong and it does not work because i have a constructor to take in Ingredients but because it is inside the loop, it cannot take it in.
I want to add a Refresh button to my frame to refresh the data from the database, but I'm not sure how to refresh the data in the jtable. The constructor below initially creates the table and displays the data. Should my button destroy/create the JPanel all over, or is there a single method within the TableModel that will redisplay the data?
class TablePanel extends JPanel {
private Connection con;
private JTable table;
TablePanel() {
try {

When I click on a row in a JTable, I want to have a row appear above it. For now I'm just making that row be a duplicate of the row I clicked on, but eventually this will be some sort of previous history of that row, so as you are editing the row you actually clicked on you can look directly above it and see what the data used to look like.
I"m not having any problem creating the row, nor am I having an issue getting it positioned correctly. What I want to do with this added row is made it so you can't edit the entire row, and also really make this row stand out. I'd like to say make this row stand out or "POP" so to speak so there is no confusing what it is. I'd almost like to make it look like the row header or even better... Most of what I am seeing are ways to make particular cells uneditable, so I think my backup plan is that, but Is there a good way to do what I described?
I am attempting to show a GUI that will show records from a SQL Server table. That part I have done. However, I need to allow the user to be able to edit the Approval field of the table when he/she views it. Following is my code:

import java.util.*;
import javax.swing.*;
import javax.swing.table.TableColumn;
import java.awt.Font;
import javax.swing.event.ListSelectionListener;

My latest issue was that I wanted to only get a double value into a JTable Cell.
So first I Overrode the getCellEditor(int row,int col) method of my JTable, so if I was in a cell i knew I needed a double value I returned my Editor.
My editor filters out anything but numbers. I also check to make sure we get one and only one decimal point.
Other solutions Ive seen use keyboard Listeners, but to me that doesn't work. What if the user cuts and pastes data? My solution handles that as well.
It doesn't handle if they try to cut and paste something like 1234abcd.bob.123.23 , this would result in 1234..123.23 pasted in. I'll handle faulty values on the getValue method of my AbstractTable, but as long as the user is using mostly valid data this works well.
public TableCellEditor getCellEditor(int row, int col) {
if (row==TheRowWant && col==TheColumnI want) {
return (new DefaultCellEditor(createDoubleTextField()));
}
}
private JTextField createDoubleTextField() {
final JTextField field = new JTextField();

I am having a problem finding string objects in a jTable. I use setValueAt() to write string variables into a jTable.
I can then use getValueAt() to search to find any of those strings. All works fine until I edit an entry in the table. Then I can never find that string again.
In fact, if I just click in the cell type a character, then delete that character, something changes. The contents of the cell look the same but the search for it doesn't find it.
For example if I have a string "xyz" that was written in a cell. If I set the search value, "a=xyz", and "b=getValueAt(some cell)".
Then at the compare:
if(a==b) I can hover over a and b and I see that;
a = (java.lang.String) xyz
and
b = (java.lang.String) xyz
[note I am using NetBeans to do this]
after the compare, the true path is taken .
If I then click in the cell then click out and try the same compare, everything is exactly the same including what gets reported when I hover. But the false path is taken at the "if".

View Replies View RelatedI'm having serious issues right now with a JTable inside a JScrollPane.i have some methods that returns different indexes (rows) that i select programatically in a JTable and the problem is that sometimes it goes beyond of what i can see, like, the row gets selected but the scrollbar won't follow up.
i've searched up in google and saw several different methods but those were extremely complex and for stuff i don't need.the simplest solution i found is this:
tInfo.setRowSelectionInterval(searchIndexes.get(currentIndex), searchIndexes.get(currentIndex));
tInfo.scrollRectToVisible(tInfo.getCellRect(currentIndex, 1, true));
but it just doesn't do anything.My table (tInfo) has only two columns so no horizontal bars, just vertical. What can i do to align the scrollbar with the currently selected row in my table? :C
Found a solution using scrollPane.getVerticalScrollBar().setValue();in another thread, i didn't even notice there were like 3 more threads about the same, just different kind of code used in each.
I am trying to set the font of the editor as the same for the renderer of JTable. I am just a bit confused on how to do this. I don't want any code but maybe a walkthrough on what to do. Here is my abstract table model ....
public class ProductTableModel extends AbstractTableModel {
private ArrayList <Product> prodList = new ArrayList <Product> ();
private String [] columnNames = {"ID", "Description", "Inventory", "Cost", "Order Quantity"};
public ProductTableModel (ArrayList <Product> productList) {
this.prodList = productList;

I have been trying to learn a bit about JTables for a project I want to undertake. I have created a new JFrame in netbeans and added a button. Onclicking the button I want add some data to a JTable model and then output the JTable with the data. When I click the button again I want the same process to happen again and overwrite the previous table being displayed.
I have written the following code below:
import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
[code].....
The problem I have is that when I click the button for a second time the table stays on the screen exactly as it did following the first click. I can see that the data in the model is changing so I am not sure why a new JTable is not drawn.
