This is how the behavior in ext js.
I did it by keeping track of selected rows, on GridCellListener and
GridHeaderListener
Here is the sample code :
//selectedRowId is a simple ArrayList, which holds the row position in
grid
grid.addGridCellListener(new GridCellListenerAdapter(){
public void onCellClick(GridPanel grid, int rowIndex,
int colindex,
EventObject e) {
RowSelectionModel rowSelectionModel =
grid.getSelectionModel();
Integer rowInt = new Integer(rowIndex);
if(selectedRowId.contains(rowInt)){
selectedRowIds.remove(rowInt);
}else{
selectedRowIds.add(rowInt);
}
if(colindex != 0){
grid.getSelectionModel().clearSelections();
int[] selectedRowIdsPrem =
getSelectedRowIdsPremitive(selectedRowIds); // this function converts
list of Integer into int[]
rowSelectionModel.selectRows(selectedRowIdsPrem);
}
}
});
grid.addGridHeaderListener(new GridHeaderListenerAdapter() {
public void onHeaderClick(GridPanel grid, int colIndex,
EventObject
e) {
selectedRowIds.clear();
if(grid.getSelectionModel().getSelections().length > 1){
for(int i = 0; i<
grid.getSelectionModel().getSelections().length; i ++){
selectedRowId.add(new
Integer(i));
}
}
}
});
I am also interested to know if there is any better solution.
