JTable DefaultCellRenderer Not Working

Jul 29, 2014

I have a jTable with two columns and in the second Column I would like to have 2 different cell-renderer. One is String and the other one is boolean. The data is always from type Object[][]. I have written an own renderer:

Java Code:

@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
if(column == 2 && row > 2){
return super.getTableCellRendererComponent(table, (boolean)value, isSelected, hasFocus, row, column);
}
return super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); //To change body of generated methods, choose Tools | Templates.
} mh_sh_highlight_all('java');

I set the default renderer in my form:

Java Code: jTable.setDefaultRenderer(Object.class, myRenderer); mh_sh_highlight_all('java');

So the problem is, that my JTable will always renderer to String. I thought when i write "(boolean)" before "value" (in my IF-Statement), he returns the boolean cell renderer. But it isn't doing that.

How can I return a boolean-renderer in my column 2 with all rows higher than 2 ?

Link Not Working In Jtable

May 26, 2014

The JTable that I'm using in my program fetches its value from the database. Now one of the fields contain the link item. I basically want it to be clickable so that once the user clicks on this link then he is directed to the desired webpage. I've tried to implement this in my code but somehow nothing seems to work.

Java Code:

public class JTableButtonMouseListener extends MouseAdapter
{
private final JTable table;
public JTableButtonMouseListener(JTable table) {
this.table = table;

Editing Jtable After Item Change Using Jcombobox Is Not Working?

Jan 23, 2015

I'm making a project about school management system , i have a jframe to set marks and inside the jframe i have a jtable which is connected to sql database , in the jframe I have a JCombobox with 6 different subjects and in my database i have created 6 tables for the subjects and if any of the subjects are clicked then the jTable will connect to database and change the table to that subject , after it is changed if you double click on any row and insert a value then it will automatically update the table in the database , but my problem is that if I select the first option from the jcombox which is English and edit the values then it works fine , but if I select any other option e.g Math or Science , then I try to edit the table then it edits the English table , I commented the English option in the code to see what happens and I saw that it edits only the first option and if you try to change the subjects and edit than it edits the first subject in the combobox , so how can I solve this ?

CODE:

import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JLabel;
import java.awt.Font;
import javax.swing.JComboBox;
import javax.swing.JTable;

How To Compare Two JTable And Set Value From One JTable To Other One

May 26, 2014

I need to compare two jtable and set the value from one jtabel to the other jtable.

jtable one consist of:

Unit ID Unit Name Access

ABC, Inc ABC Incorporate (checkbox) value = uncheck

CDE, Inc CDE Incorporate (Checkbox) value = uncheck

jtable two consist of:

Unit ID Access

ABC, Inc ABC Incorporate (checkbox) value = checked
CDE, Inc CDE Incorporate (Checkbox) value = checked

if comparing jtable one an jtable two has the same Unit ID then colum Access from jtable two value is set to jtable one become check based on jtable two.I did the code but did not work:

for (i = 0, jTable1.getrowcount(), i++) {
for (j = 0, jTable1.getrowcount(), j++) {
if (jTable1.getvalueAt(i,0) == jTable2.getvalueat(j,0)) {
jTable1.setvalueat(true,i,2)
}
}
}

above code i try did not make any changes.

How To Add Row Names To JTable

Jan 17, 2015

I'm trying to implement a spreadsheet-like table using JTable and this is the basic structure.

String[] colnames={"A","B","C","D","E"};
String[][]data=new String[28][5];
sheet = new JTable(data,colnames);
//sheet.setBounds(10, 36, 527, 214);
JPanel tablepane=new JPanel();
tablepane.add(new JScrollPane(sheet));
tablepane.setSize(800, 400);

In a spreadsheet, alphabetical letters are column names and numbers represent rows. I have named the columns and I need to name the rows in the same way. Or if I am to set the first column in every row as row headers, how can I make then non-editable by the user? In addition to that, how can I make the table appear bigger? There's a lot of space but the table appears to be small.

Bufferedreader Into Jtable

Dec 6, 2014

I have created Jtable which stores images and Strings, I can SAVE the content to external file, however whenever I will try to load it back (below code) to JTable, it throws me an error. One field in the JTable uses renderer for images, and the code throws everything back as a String ) how can I transform one 'word' (e.g. /usr/etc/test.jpg) in a text file to ImageIcon which will be handeled by the renderer? Should I read the file 'word' by 'word' store it as array and load it into column?

private void check() {
String path = "Tab.csv";
File source = new File(path);
if (source.exists()) {
DefaultTableModel mdl = (DefaultTableModel) Tab.getModel();
String line;
BufferedReader reader;

Swing/AWT/SWT :: JTable With Fixed Row

Nov 9, 2008

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.

Swing/AWT/SWT :: Can't Select The Very Last Row In A Jtable

Mar 26, 2015

I 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?

Swing/AWT/SWT :: JTable Not Getting Updated

Nov 17, 2014

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();

Java Swings JTable

Nov 18, 2014

I have a panel which has set to cardLayout and at the bottom, I have the buttons, based on the button clicked I will change my cards further and back. My second card has Jtable which allows the user to edit a particular cell. Now my problem is for the first time, when the data is inserted into the table, the particular column's cell is getting editable and allowing user to edit the cell and take the value what user gives. But when I come from 3rd card to the 2nd card, I have to show the previous created table or again from my 1st card if I move to the second card (in the same opened application), the cell's in the jtable is getting editable but not allowing the user to enter the text to the cell?? why is this problem coming?? I tried repainting that table when I move from 3rd card to 2nd card, and when coming from 1st to 2nd card the jtable rows are removed and new rows are inserted. But still the same problem arrives?? why is it working correctly in the first time and not able to in the second time??

Swing/AWT/SWT :: JTable Sum Of A Column

Feb 9, 2015

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?

How To Print Preview A Jtable

Apr 9, 2014

I want to build a class that takes a JTable and previews on screen how it will be printed on the default printer. This is what we use to call as "Print Preview", just like MS Word, Excel, etc.

As we already know Java does not support this functionality out-of-the-box.

Based on some examples I've found googling I built two classes. The first one TestPreview.java justs shows the JTable and the second one PrintPreview.java previews how the JTable will be printed on the printer.

I have two buttons to go through the pages, "PREV" and "NEXT" and "Print' button to print the JTable. My problem is that when my JTable has too many rows and spans in more than one page PrintPreview does not work. It shows the same page again and again. Also, it does not show the entire JTable data, but only some of them and I can't figure out why.

Below is my two classes

TestPreview.java
package printpreviewdemo;
import javax.swing.*;
import java.awt.BorderLayout;

I can change this in the print dialogue however I would much prefer if I could change this programmatically. I wont post the whole program as there is a lot of code(800+ lines) but here's the print method.

Code:

public void Printtable() {
boolean fitWidth = true;
boolean showPrintDialog = true;
boolean interactive = true;
JTable.PrintMode mode = fitWidth ? JTable.PrintMode.FIT_WIDTH

How can I say the jTable, that she should scale to the size of the content?

I don`t want that the jTable is bigger than the content. For example the picture below:

pList.add(pListl);
tabbedPane.addTab("Player List",pList);
tabbedPane.setMnemonicAt(0,KeyEvent.VK_1);

Yes I am spamming entries into the result object, this is so I can test the scrolling as right now I don't have enough data for overflowing entries but will do soon.
