Question

JTable row select

Asked by: John4343

How do I get a row in JTable selected when user clicks on first column in that row?

Rest of the time I want user to be able to block individual or group of cells so I have:

myTable.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
myTable.setCellSelectionEnabled(true);

>> Rest of the time I want user to be able to block individual or group of cells so I have:
What do you mean with block?
I don't know if I understand you well, but if you *don't* want users to be able to select individual cells, you should have

myTable.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);  // = selected rows shouldn't be consecutive
myTable.setCellSelectionEnabled(false);  // false instead of true = you can't select individual cells

Then clicking in whatever column of a row, selects automatically the whole row.
Is that what you want?

Sorry for lack of clarity (and delay is response).

I want user to be able to select an individual cell or a block of cells by clicking and draging across a rectangular block of contiguos cells.  In addition select a single row.  For row selection I thought I could put a select arrow in the first column which, when clicked, would select the complete row.

Then you have to add a mouselistener on the table and listen for mouse click and mouse release

The mouseevent has a point and with that one you can get the row and the column of the start/end of the drag:

JTable has the methods:
columnAtPoint(Point point)
rowAtPoint(Point point)
