Getting the Selected Cells in a JTable Component</h3>
The method for determining the selected cells depends on whether
column, row, or cell selection is enabled.
<pre>
JTable table = new JTable();
if (table.getColumnSelectionAllowed()
&& !table.getRowSelectionAllowed()) {
// Column selection is enabled
// Get the indices of the selected columns
int[] vColIndices = table.getSelectedColumns();
} else if (!table.getColumnSelectionAllowed()
&& table.getRowSelectionAllowed()) {
// Row selection is enabled
// Get the indices of the selected rows
int[] rowIndices = table.getSelectedRows();
} else if (table.getCellSelectionEnabled()) {
// Individual cell selection is enabled
// In SINGLE_SELECTION mode, the selected cell can be retrieved using
table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
int rowIndex = table.getSelectedRow();
int colIndex = table.getSelectedColumn();
// In the other modes, the set of selected cells can be retrieved using
table.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
// Get the min and max ranges of selected cells
int rowIndexStart = table.getSelectedRow();
int rowIndexEnd = table.getSelectionModel().getMaxSelectionIndex();
int colIndexStart = table.getSelectedColumn();
int colIndexEnd = table.getColumnModel().getSelectionModel()
.getMaxSelectionIndex();
// Check each cell in the range
for (int r=rowIndexStart; r<=rowIndexEnd; r++) {
for (int c=colIndexStart; c<=colIndexEnd; c++) {
if (table.isCellSelected(r, c)) {
// cell is selected
}
}
}
}
