Problem faced with Jtable

Question

I have a row added to JTable.I am trying to edit column 2 in it.Now i keep my cursor in the same column which is being edited (i.e the focus remains in the column being edited) & click on Cancel Button
By means of this button i clear the Jtable.i.e delete the row which is added to it.
Now i add 1 more row to this Jtable.
The same column of the newly added row displays the contents which had been edited previously.
Eg : Row consists of 3 columns Col. 1 : Name
Col 2 : Roll No
Col 3 : Place .
Assume that i add a row with name pradeep Roll No. 2 & Place - Mumbai.
I edit col. 2 having roll no. 2 & make it 3.Keeping the focus here only i click on cancel.
This row has been thus deleted.Now i add a new row..which has name : Manish Roll No : 5 & Place : Mumbai.But Column 2 shows 3 instead of 5.
I have tried Jtable..repaint();
jtable.updateUI();
jtable.lostFocus();
jtable.getCellEditor().stopCellEditing();
however still this happens...is there any way to make jtable lose focus externally.....or any other way to handle this.

Answer 1

It's the same what i have explained, though it's not real stuff..the idea is the same....yet i have clarified things below also...i have an textfield wherein i enter the main code.I click on enter & the details related to this code get added to the grid.Like in the example given be4...Let's assume i enter 1 i.e the code in the textfield & click on enter.The details related to 1 are Name : Pradeep Roll No. : 2 & Place : Mumbai.(Note that Name,Roll No & Place are column names)
This gets added to the grid.Now i change the Roll No. which is currently 2 to 3.My focus is in this column.For some reason i don't need this record & click on cancel button.
Now i enter 2 in the Textfield & click on enter. The details expected to be seen in the added row are Name : Manish , Roll No. 5 & Place Mumbai.But what is seen instead of this is Name : Manish , Roll No. 3 & Place : Mumbai.Also the focus is already in column 2.
When we edit a column the code added changes the column data & then calls
jTable.getCellEditor().cancelCellEditing().
The code on clicking cancel calls
jtable.repaint();
jtable.updateUI()
if (jtblBarCodeDetails.isEditing()) {
jtblBarCodeDetails.getCellEditor().stopCellEditing();
well.....that is it..
