I have one JTable which contains some columns with String and two columns for Edit and Delete. I have added ImageIcon on JLabel, and set that label in JTable for all rows. Now I want to set MouseListener for that JLabel(as there is no way to set MouseListener for ImageIcon).
How can I set MouseListener to JLabel inside JTable?
I can get which cell clicked by user, but I want to set Listener only.
Please suggest me....
As I found there is no way to add direct listner to components inside JTable. You have to go with JTable's listener only.

I have a Java connection with MySQL database. I inserted 30 variable to a MySQL table. I would like to create a graphical interface with Jframe where I can select the variables from the table using a checkbox.
I plan to do something similar as Java Swing Group of checkbox multiple selection handler
But I do not know how I can use it with NetBeans? I tried to add a newJFrame where I add a jScrollPane and I wanted to add multiple jCheckBoxes but I can add only one to jScrollPane.
Could someone let me know how I should add a group of checkboxes to jScrollPane?
You have to add a JPanel to your JScrollPane, then add checkboxes to that JPanel.
JPanel panel = new JPanel(layout);
panel.add(checkbox1);
panel.add(checkbox2);
JScrollPane scrollPane = new JScrollPane(panel);
I have a table created over AbstractTableModel. In this table I have a rows. And I need add ActionListener with parameter from column "ID from database" - viz. Image. This ActionListener should call when you double click the row.

So my question is how to get the parameter from the table ActionListener to JDialog.
Thank you for any help.

Use JTable#columnAtPoint(Point) and JTable#rowAtPoint(Point) to get the row and column values for the point the user clicked at
Use JTable#getValueAt to get the value of the cell at the given row/column position
I have a JTable inside a JScrollPane. I have put this inside a panel. As soon the panel loads I want the first row in the JTable to get the focus BUT by default the focus goes to the JScrollPane and on pressing tab the focus enters into table's first row.
I dont want to use setRowSelectionInterval(0,0) and setColumnSelectionInterval(0,0) as my requirement is different from that.
If you want to edit cell you can use,
jTable1.requestFocus();
jTable1.editCellAt(row,column);
Or else you want to just select the row, you can use,
jTable1.requestFocus();
jTable1.changeSelection(row,column,false, false);
try with myTable.changeSelection(row, column, false, false);
depends of ListSelectionModel
I have a problem in my table model to update the data I print in it.
I have the class AgendaTableModel who is the table model, and the class Screen that is the main UI, when I press the button 'Listar Contatos' the table model should appear on JScrollPane in the center of the JFrame, but it continues blank.
What should be the problem ?
You should really post the code or better an SSCCE.
Here's the Oracle's tutorial on JTable.
I'll give you some hints:
Each JTable has a TableModel associated
You don't display the TableModel but the JTable, that is a view of your model
When you add components dynamically you should revalidate the parent component, so if you are adding a JTable somewhere, try to revalidate its container.
If you are trying to add the JTable to an already existing JScrollPane (empty or containing something else), consider to instantiate a new JScrollPane rather than updating its content.
I have a list of names and associated values to create checkboxes like
["SAMABULA","CARPETS INTERNATIONAL","HRM/TRAINING"]
["091","094","003"]
How to create checkboxes with these values add these checkboxes to JScrollPane in Netbeans IDE.
This is a Swing application. I created a window from palette and added jscrollpane to that window. But I don't know how to add list of checkboxes to that scrollpane.

there are two areas
you have already JList that's contains JCheckBox(es)
then you just declare
JScrollPane myScrollPane = new JScrollPane(myList);
or you have to put your JCheckBox to JList or JPanel but for JPanel with correct LayoutManager for example GridLaoyut
thenarter add your JList or JPanel to the JScrollPane as is above mentioned
maybe ButtonGroup Component can help you with that
Not sure how to add them in NetBeans as i use Eclipse, but in code would be something like:
JCheckBox chk = new JCheckBox("[LABEL STRING]");
// add event listeners to chk
myScrollPane.add(chk);
see here for more detail and examples: http://download.oracle.com/javase/tutorial/uiswing/components/scrollpane.html
In Netbeans you just drag and drop the Check Boxes where you need them. In an Action Listener you use jCheckBox1.isSelected() in order to check if the user has checked the box or not.
