I have a JTable whose every cell contains a JList. What I want to do is to make that table editable so that every item on the JList can be edited either using a JTextfield or Choosing an item from another List whenever the user right clicks on that list item in a particular table cell. I also want 2 of my table column need to be set uneditable. Here is a picture of my JTable. I want the every cell and every JList item on that cell to be editable leaving the 'Batch' and 'Break' column to be uneditable.
P.S. I don't want any spoon fed code. I just want an idea how it can be done. And I'll be really grateful if you can reference me some link on the web where I can read to learn how this type of problems can be solved. Thank you..!

I have created JTable with TableModel in which I make column Product Id as editable. This jtable is shown when i click one cashMemoBtn and if i type product id in first row and hit enter key then it is adding new empty row to jtable. But my problem is when new Empty row is added then Product Id Cell should have blicking cursor like we see in any editor OR in textfield.
I have attached my expected output screenshot here
In image you can see vertical bar which is indicating current focus but i want it should be automatic for all new rows when i add new rows.
I tried with
jTable.setEditingColumn(1);
jTable.setEditingRow(0);
But is not working as per my requirement. Please help.
Thanks in advance.
After you add the empty row of data to the table you then need to start editing on the desired cell.
The basic code would be:
if (table.editCellAt(row, 1))
{
Component editor = table.getEditorComponent();
editor.requestFocusInWindow();
}
I have a JavaFX TableView with some columns and some rows. Each column has a custom TableCell to be edited, for example: some columns use text fields, some others use check boxes, choice boxes and so on.
What I want is to edit several cells (simultaneously) in the same column by doing the following:
Select some rows in the TableView.
Click on a cell using the right mouse button.
A context menu is shown with the option "Edit All"; choose it.
Somehow I edit one of those cells and every cell in the same column whose row is selected commits the same value.
What I want to know is whether it is possible for every cell to “commitEdit” the same value. I cannot find the way of doing it.
Thanks in advance.
I have a JTable. One column in the JTable is assigned an extended TableCellEditor that displays an extended JComboBox.
There is a fixed list of 100 String objects that populates the comboboxes.
The challenge:
Design the JComboBoxes so that any selection is unique relative to other boxes? That is, if "A" is slected from the combobox in the first row, it is automatically removed from the list of each other combobox.
When a new room is added to the table, the combobox it contains should auto-populate to the first available list item.
The problem:
My comboboxes work beautifully. I can select items at will. I even have made some progress in eliminating already used items from the lists. But I can't figure out how to correctly auto-populate.
I am very confused because it appears that my combobox constructor is only called once when the table is created, not once for each row.
Is this the case? Is the constructor for a TableCellEditor only called once ever? If so, how do I modify the behavior of each combobox as it come into existence?
Thanks for your help!
If you would like specific code, please let me know. I don't know if you want me to paste in the whole classes.
When a new room is added to the table, the combobox it contains should auto-populate to the first available list item.
When you add a new row of data to the TableModel you must add the values of all columns in the row. This should not be a function of the editor. The editor allows you to change values in the cell.
I was able to get around my problem by creating an abstract superclass for my combobox that can be accessed from the tablemodel extension when it sets up its data.
I have a JTable with Customized CellRenderer and CellEditor, Intially the table is loaded with
a list of values Say with 12 rows and 5 colums, I have a JTextField at the top of the table in which I applied KeyListener and made the Textfield to display like a JComboBox with a list of values as soon as first 3 characters typed in that field, eg. Typing 'met' will display all the medicine names starting with "met", now what I want to do is I have to Implement that Textfield into the Jtable's last row's 2nd column Say 13th row in the situation I mentioned above. and after selecting any 1 medicine from the list of displayed value the JTable could Add a row dynamically and insert a new row with that search textfield, Please Suggest me an Idea and Code for this, also guide me how to apply cellrenderer and celleditor for a particular cell(Cell which contains the dynamic search textfield)...
Thanks a lot in Advance :)
Kindly let us assume jTable2 be your JTable variable name and TextField be your JTextField variable name. Then use the following code with the keylisterner of the text field to get what is wanted:-
javax.swing.table.DefaultTableModel dft= (javax.swing.table.DefaultTableModel)
jTable2.getModel();
jTable2.setModel(dft);
dft.addRow(new Object[1]);
jTable2.setValueAt(TextField.getText(),jTable2.getRowCount()-1,1);
I have a swing layout with some labels and a jTable.
On the left side, I have the jTable, and on the right side I have the labels.
I want to set the page up as a master / detail page, where the jTable is the master, while the labels act as details.
I have found a way to get the index from the jTable - my question. What kind of listener can I use to tell if the user selects a row in the table?
You need to get the JTable's selection model (using getSelectionModel()) and add a ListSelectionListener to this model.
Make sure to use convertRowIndexToModel to convert the index of the selected row to an index in the table model: if the table is sorted or filtered, the view and model indices won't be the same.
