HierarchicalTable singleExpansion row locking

[therodet]

As of right now, the options with the expansion of rows in a HierarchicalTable are either to have the user manually expand and collapse each row, or to have each row expansion collapse any other exapnded rows (via the setSingleExpansion function). I think it would be nice to have an intermediate option such that with singleExpansion set to true, a row can be "locked" open so that subsequent row expansions will not collapse the rows that have been locked in the expanded, but any expanded unlocked rows will be collapsed.

I can understand what you asked but do you have a good use case?

Thanks,

What I am wanting to do is to create a table that functions in a manner similar to the HierarchicalTable demo you provide where clicking on a row atuomatically expands that row showing a few basic options, and collapses the others, but with the addition that I would leave the expansion handles visible, and if the user clicks the handle to expand the row, then the row would expand with a more detailed view, and stay there until closed. I would distinguish between the two expansion methods by setting a flag in the mouse click listener.

In this case I suggest you to disable build-in singleExpanion flag and wrhite your own logic to do it in ListSelectionListener. You just need to change the code in TradingHierarchicalTableDemo to get singleExpansion feature when single clicking on row.

Code: Select all

        table.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
            public void valueChanged(ListSelectionEvent e) {
                if (table.getSelectedRow() != -1) {
                    table.collapseAllRows();
                    table.expandRow(table.getSelectedRow());
                }
            }
        });

Thanks,
