Editing JList in a JTable

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..!

Jtable losing multiple row selection,when button in one of the column is clicked

I have a very basic problem with jtable. I have a jtable that has multiple columns with one of column having a button. When i click on that button a panel drops, and asks to select an option from given options. When i select that option, value replaces in one of the column.
Now, i want when i select multiple rows, and do the same thing as above, it should replace that column in all the selected rows.
Problem: Currently, my table is losing selection when i am clicking the button in one of the column in jtable after multiple row selection.
I searched google and stackoverflow a lot, but could not find anything meaningful. Anyhelp or sample code is appreciated.
Thanks

If I understood your problem correctly then the solution is fairly simple.
First of all the issue probably occurs because once you click on the button java sets a new focus on the button and therefore clearing the focus on the other rows. That won´t be a problem in a single selection because you still click into the selected row, however doing that with multiple rows in one go won´t work that way.
To solve this you need to save your previous selections in something like an ArrayList and after the whole option thing you can apply the changes to every element in the ArrayList and reload the table.
A cleaner and more intuitive approach though would be to place the button outside of the JTable.

Checkbox column editing on JTable

I have a JTable in which one column is a checkbox. I want to let the user edit the checkbox by mouse drag: if they clicked one checkbox and drag mouse into other checkbox, they will get the same result with the first checkbox clicked.

One approach is to specify ListSelectionModel.MULTIPLE_INTERVAL_SELECTION for the table's selection model, as shown here. Click and drag to select contiguous rows, or add the shift, control or command modifiers to select disparate rows. In a suitable Action, update the TableModel to reflect the selection, as shown here. The JTable will update itself in response.

How to edit multiple cells in JavaFX TableView?

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.

how to force cell editor in jtable to accept edits

i have a jtable with multiple editable cells
when someone presses the "save button" on the menu, it doesn't save the last value that is still currently being edited. (unless they tab out of the cell first)
i can check it is being edited by calling .isEditing() which returns true.
What i would prefer to do is trigger that the cell editing is complete, and it can show any validation errors, and if none, then save. (without the user having to tab out first)
can someone please point me in the right direction
thanks

You can manually call:
JTable table;
table.getCellEditor().stopCellEditing();
This should cause the table to stop editing at that cell. By overriding the stopCellEditing() method of your TableCellEditor and returning false under certain circumstances, you can indicate that the cell's value is currently invalid and thus editing cannot be stopped at that time.

when you have a jtable with multiple editable cells
when someone presses the "save button" on the menu, it doesn't save the last value then please add the below peace of code
The first is to have the table automatically stop editing and save the data. This can be done by setting a property on the table:
JTable table = new JTable(...);
table.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
It will make sure that when someone presses the any button on the menu, it saves the last edited value also.

If I remember correctly, edited/added value is present in cell editor component by default it is EditBox, BUT do not present in table model. If it is possible try to check cell editor component it should help you.
