JTable multiple selection without using keyboard only using mouse

Question

Here is my code. I want to select multiple rows in JTable, I am using the following line:

table.getColumnModel().getSelectionModel().setSelectionMode(
    javax.swing.ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

With the above line I am able to select multiple rows using keyboard, but requirement is to select only using mouse.

Is there any thing other than this, that Java provides for multiple selection only using mouse without using keyboard?

I missread `provides for multiple selection only using mouse without using keyboard` not possible directly, because ListSelectionModel is only one dimensional, this is implemented in API only for JList and JTree — mKorbel, Jul 05 '12 at 08:14

If you have this code, you need only yo push ctrl + click multiple.

Edit: But if you don't want to use keyboard it's possible i think, try this:

How do you press ctrl only with the mouse? – JB Nizet Jul 05 '12 at 07:09

I don't think it's possible. I suggest adding an additional column to the table, containing a checkbox allowing to mark the row as selected. Of course, you won't be able to use the table selection model to know which rows are selected.

+1 and he can use the selection model if he binds the checkbox value to the selection model in his table model. – Guillaume Polet Jul 05 '12 at 07:46

Yes, you can select multiple rows without using keyboard by overriding the changeSelection function, like this:

@Override
        public void changeSelection(int rowIndex, int columnIndex, boolean toggle, boolean extend) {
            latestClickedRowIndex = rowIndex;
            ListSelectionModel selectionModel = getSelectionModel();
            boolean selected = selectionModel.isSelectedIndex(rowIndex);
            //throw new UnsupportedOperationException("Paila.");
            if (selected) {
                selectionModel.removeSelectionInterval(rowIndex, rowIndex);
                getValueAt(rowIndex, columnIndex);
            } else {
                selectionModel.addSelectionInterval(rowIndex, rowIndex);
            }
        }

I finally used this code:

JTable table = new JTable(){
    @Override
    public void changeSelection(int rowIndex, int columnIndex, boolean toggle, boolean extend) {
        super.changeSelection(rowIndex, columnIndex, true, extend);
    }
};

This way CTRL(toogle) is always pushed(true).
