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.

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 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 want to make a whole Row editable...e.g if user selected column 1 than click on edit button the table will show the whole row in editable form...it will be great if any one can give only code upon button event.

I think have to use JToggleButton, because (JButtons) simple click is immediatelly finalized in comparing with JToggleButton (has two states)
for JTable have to set proper SelectionMode and to override public boolean isCellEditable(int row, int col) {
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.
I have a JTable with 4 columns that are required. When a users finishes one cell, they can click out of the row. I want to force the user to fill in all values before they can continue. Is this possible?
Thanks
Create a popup dialog to add a new row of data to the table. Then the dialog "Save" button can check to make sure all four fields are filled in.
