Column Click

[Arun Sanker]

Hi Guys,

I have rendered a Jtable with ComboBoxes as shown in figure.The first column is a header column.

When the user selects the first column(ie: with 0 index & no Comboboxes ),I want to know that.
How will I know that the user has clicked on the first column

Thanks

You can add a ListSelectionListener to the columnModels selectionModel
table.getColumnModel().getSelectionModel().addListSelectionListener()
and listen for changes in the selection. You can use
table.setColumnSelectionAllowed() to help isolate the selection.
Or you can add a MouseListener/MouseAdapter to the table and in mousePressed look for the
column index zero with
table.columnAtPoint(e.getPoint()). The tricky part is that if you allow the user to
drag the columns around this will give the view column index. You can get the correct column
model index from the TabelColumnModel.
